INFORMATION TO BIDDERS

1. INTRODUCTION

Kochi is the commercial capital of Kerala and today it is the

largest and the most modern city in Kerala. Across its bay and on

the islands are the villages of Vypeen, Bolghatty and Vallarpadam.

Bharat Petroleum Corporation Limited (Kochi Refinery)’s SPM terminal

is located in the Arabian Sea off Puthu Vypeen, which is an

extension of Vypeen formed by sand deposition from sea and is

located about 12 km N.W of Ernakulam town. Puthu Vypeen area is

under administrative control of Cochin Port Trust (CPT). Shore Tank

Farm (STF) has been constructed at the 70 Ha of land allocated to

BPCL (KR) by CPT.

The salient features of the weather and oceanographic conditions

prevailing in Kochi region are described in the following section.

2. GENERAL CLIMATE

The climate of Kochi region according to Koppen’s classification is

tropical monsoon climate with seasonally excessive rainfall and hot

summer. The region is characterised by annually recurring seasons or

periods, which divide the year into three parts.

The period from March to the end of May is the hot season. This is

followed by the southwest monsoon season, which continues till the

middle of October.

From the middle of October begins the northeast monsoon season,

which lasts till the end of February, although the rains associated

with the North-East monsoon ceases by December and the rest of the

season is generally dry.

The climate is pleasant from September to February. Summer months

from March to May are uncomfortable due to high temperatures and

humidity.

3. WIND SPEED AND DIRECTION

Average wind conditions near Kochi show that the highest wind (10.9

km/hr) occurs in the month of May and lowest (6.7 km/hr) in

November. Wind speed on some days may have higher values (12 to 20

km/hr) during pre-monsoon and monsoon months. In general winds are

quite strong during afternoons when the thermal circulation is best

developed and week during night / early morning.

The predominant wind direction in the region is NE-E in the morning

and W-NW in the evening throughout the year indicating diurnal cycle

of winds due to land-sea breeze effects. Only during July, August

and strong monsoon period, prevailing conditions do not permit the

diurnal cycle of winds to exist.

The Environmental conditions for 1 year period are presented in

Table-1 for reference.



15

4. AIR TEMPERATURE

Average air temperature over the region showed a variation from

23.2º C in January to 31.4º C in April.

Temperatures begin increasing after February. March and April are

generally the hottest months when the mean daily maximum temperature

is 31.4º C and the mean daily minimum is 26.0º C.

With the onset of the southwest monsoon by the end of May, day

temperatures decrease slightly and the whole of monsoon season is

more pleasant.

After the end of September, day temperatures increase gradually, and

the heat in the post monsoon and northeast monsoon seasons are

nearly as intense as in summer.

The highest maximum and minimum temperatures ever recorded were

34.6º C in May and 17.8º C in January respectively.

The month-wise distribution of mean maximum and minimum temperatures

and also the highest and the lowest temperatures recorded are

presented in Table-2.

5. RELATIVE HUMIDITY

The air is highly humid throughout the year, the relative humidity

being generally over 70%.

6. CLOUDINESS

Skies are heavily clouded to overcast in the southwest monsoon

season. In the pre-monsoon month of May and post-monsoon months of

October, November and few days in December, the skies are generally

moderately to heavily clouded. In the other months, clear or

lightly clouded skies are common.

7. RAINFALL

The southwest monsoon at Kochi generally sets in during the last

week of May. The rainfall in the southwest monsoon months, June to

September constitutes about 65% of the annual total of 305 cms. June

and July are the rainiest months when 44% of the annual rainfall is

received. The rainfall gradually decreases after July. A good amount

of rain, mostly as thundershowers, occurs in May and in the post-

monsoon season.

On an average there are 132 rainy days (that is, the days with

rainfall of 2.5 mm or more) in a year.

The heaviest rainfall in 24 hours recorded was 253.2 mm on July 28,

1933.

The monthly distribution of average rainfall, the average number of

rainy days and the heaviest rainfall recorded in 24 hours in each

month are presented in Table-3

8. DEPRESSIONS AND CYCLONIC STORMS



16

From the records of India Meteorological Department during the past

104 years from 1891 to 1994, it was observed that a total number of

28 depressions (winds up to 33 knots) and cyclonic storms (winds up

to 47 knots) might have acted in the area with strong winds, heavy

rains and also moderate to high sea wave conditions. There are only

two storm seasons:

October, November and December, when majority of the storms affected

the region (89%). Only one storm affected the region in October

(originated in the Arabian Sea). All the other storms that affected

the region are in November and December (originated in the Bay of

Bengal).

May, when few storms affected the area (11%).

9. VISIBILITY

The visibility or the transparency of the atmosphere generally

refers to the maximum horizontal distance at which objects can be

clearly seen and distinguished. Monthly average visibility in the

area was more than 4 km during majority period of the year. There

was not a single instance when the visibility was less than 1 km. In

general, low visibility was observed in the month of January.

10. SPECIAL WEATHER PHENOMENA

Convective activity is essential for the occurrence of

thunderstorms. With the advance of summer, thunder activity becomes

pronounced due to ground heating. Since sufficient amount of

moisture is present in the atmosphere, a good number of

thunderstorms occur in the summer months and the post-monsoon and

early northeast monsoon seasons (64 days in a year). Being a coastal

region, the ground heating is not sufficient for the thunderstorms

with hail.

Squall is the gustiness of wind in association with thunderstorm,

dust storm etc. The squall speed may reach 30 to 40 knots. The

climatological data shows that the area may experience squall in

association with thunderstorms in about 1.6 days in a year,

especially in June and July.

The other special weather phenomenon such as dust storm and fog also

does not occur in the region.

11. WAVE CLIMATE

The wave activity in the region corresponds with the seasonal winds.

During fair weather season from October to April, the significant

wave height is about 0.5m for most of the time and wave heights

exceeding 1.0 m are very rare. During rough weather season from May

to September, the significant wave height exceeds 1 m for most of

the time.

The wave periods vary from 3 to 11 seconds with frequently occurring

wave period of 7 to 8 seconds during both of the above seasons. The

waves usually approach the coast from southwest and northwest

directions.



17

The Environmental data regarding wave height is presented in Table 1

12. OCEAN CURRENTS

The ocean currents near Kochi are predominantly due to tidal

variations. The highest currents value recorded varies from 45 to

110 cm/sec during spring tides and 32 to 64 cm/sec during neap

tides.

The Environmental data regarding ocean current is presented in Table

1

13. SPM LOCATION

SPM location as established are as under:

EASTING 614191.00 m

NORTHING 1105284.90 m

WATER DEPTH 30.0 m

Seabed Features: SPM site seabed surface sediment is sandy clay. The

seabed slope at VLCC location is about 1:500.

inspections shall be carried out after detaching floatation units).

A) Visual inspection

(1) External check:



47

Attention to be paid to:

• Serious damage to hose cover and body (cuts, gouge or tears etc.)

• Permanent deformation of hose body.

• Cracks or craze on hose surface.

• Damage to flange surface.

(2) Internal check:

Look into the end of hose assembly for irregularities in the lining or nipples by utilizing

a flashlight.

• For linings:

• Blisters, bulges, cracks or separation.

• Tear, cuts or gouges.

• For Nipples:

• Cracks

• Excessive corrosion.

B) Hydrostatic test:

Each hose shall be tested with water to pressure rating of the hose being tested. The

procedure is as follows:

• Lay out the hose as straight as possible on supports that permit the hose to be

elongated freely.

• Put blind flanges on both ends and fill with water, vent to remove all air and apply a

pressure of 0.7 bar (10 psi).

• Measure the overall length of the hose assembly (X).

• Increase the pressure over a period of five minutes from 0.7 bar (10 psi) to one-half of

the rated pressure, hold this pressure for 10 minutes, then reduce the pressure over a

period of five minutes to zero.

• Raise the pressure over a period of five minutes to rated pressure and hold for 10

minutes.

• Before releasing the full test pressure measure the overall length of the hose assembly

(Y) to ascertain the temporary elongation and record the increase as percentage of the

original length (X) measured at 0.7 bar (10 psi).

• Reduce the pressure over a period of five minutes to zero.

• After an interval of at least 15 minutes, raise the pressure again to 0.7 bar (10 psi).

• Measure the overall length of the hose assembly (Z) to ascertain the permanent

elongation, record the increase as a percentage of the original length(X) measured at

0.7 bar (10 psi).

• Reduce the pressure to zero and drain the hose.

Examination of elongation:

(i) Temporary elongation (%) (T) = Y-X x 100

X



48

(ii) Permanent elongation (%) (P) = Z-X x 100

X

C) Vacuum test:

• This test shall be carried out on hose removed from service for hydrostatic pressure

tests.

• Seal off both ends with transparent plexiglass plates of sufficient strength, using putty

as a sealant or by bolting up using a soft rubber gasket. One plate shall be fixed for

connection to a vacuum source. Lay a flashlight in this end with its beam directed

towards the opposite end. An inspection mirror using sunlight may also be

manipulated from outside the plates to provide a proper light source.

Apply a vacuum of atleast - 510 millibar gauge (15 inches of mercury) and preferably

- 680 millibar gauge (20 inches of mercury) for a period of 10 minutes. Examine

inside of the hose by utilizing a light source in one end and directing it's beam to the

other end.

intelligent pig considering the declared minimum bore negotiating capability of the

intelligent pig only shall be repaired by the owner in the presence of the contractor’s

representative. Consequent to such repair, the intelligent pig supplied by the contractor

should be able to negotiate the line. During repair of dents in a particular section, no

standby / idle charges shall be paid on this account. After repair of defects, if contractor

feels, he may run gauging pig or caliper pig to re-ensure smooth passage of intelligent pig

at his own risk and cost.

4 Owner shall make its best endeavour to carry out any repair recommended by the

contractor on the basis of the caliper survey to ensure a smooth passage of the intelligent

pig. Contractor shall determine whether or not to run another caliper or cleaning pig with

Schedule and need based inspection Exhibit-B

1. Buoy Body, Deckhouse and Turret

I. General

The buoy, deckhouse and turret, and associated equipment should be subject to a general inspection at

regular intervals as specified by Engineer in Charge.

In NORMAL operation conditions check the following:

• General condition of SPM buoy, deckhouse and turret conditions.

• General condition of the installed piping.

• General condition of the mooring lugs.

• Visible damage or corrosion.

The working condition of the bilge pump should also be checked.

I. Buoy Draft and Trim

The draft of the buoy is to be monitored daily. However a visual inspection of the freeboard and trim

should be undertaken every time the SPM buoy is utilized. These readings are to be carried out in calm

sea conditions using the buoy’s draft marks. Any significant changes in draft are to be investigated

against the as-built draft figures as causes could include a leak in the buoy or a fault in the anchor chain

system. A general inspection is to be carried out above and below sea level. Any paint damage in the

SPM system shall be reported by the contractor to the Engineer in charge at the earliest.

During the underwater part of the inspection, the condition of the anodes is to be checked and also their

attachment to the buoy structure. The anodes are to be cleaned if necessary.

The amount of marine growth on the buoy and chain stoppers is to be checked. Excess growth is to be

removed using high pressure jetting system to ensure free rotation of the chain stoppers. Excessive

amount of marine growth may also affect the buoy freeboard and trim.

The fenders on the boat landing structure are to be inspected for wear or damage.

• SPM Buoy Body Compartments

The nine (9) watertight compartments in the buoy are to be sounded and inspected. The compartments are

accessible through a manhole and a fixed cat ladder. The sounding pipe enables checking the

compartments for water without opening the manholes. Before sounding, the compartment must be

depressurized by opening the vent plug. They are located next to the manholes in the buoy body, marked

with an `S’. Every month all water tight compartments shall be checked for any water/moisture presence.

Presence of water inside the compartments/ballast tanks shall be drained out.

Damage to the topcoat paint may be “touched up” as required with the provided paint if the undercoats

remain intact. Should the undercoat paint be damaged, the affected area must be completely retreated in

accordance with the paint specification as per SPM Supplier’s manual.

Detailed reports of inspections/findings and recommendations shall be submitted on completion of testing

of buoy.

The following inspection procedures are to be followed:



82

WARNING

Compartments may initially be pressurized. De-pressurize compartments via the venting plug’s prior

opening manhole cover. Venting plugs must be removed cautiously. Refer the Operating manual of

SPM Supplier before entering the compartment.

Step Action

1. Loosen and partially unscrew the vent plug, next to the sounding pipe and adjacent to manhole

cover.

2. When overpressure is equalized, remove sounding plug from the pipe.

3. Check if water is in compartment by using an appropriate line with indicating paste. Alternatively,

a small weight on a line may be lowered down the sounding pipe. Listen for the impact sounds of

the weight against the buoy bottom plate and hear of there is any sign of water in the compartment.

Repeat until you are sure of your conclusion, in case of doubt go to step 5.

4. After inspection, renew the plug O-rings as required and re-install plugs.

5. Remove the manhole cover and ensure the compartment is ventilated with fresh air and is gas-free.

6. Using a torch or suitable lamp, enter the compartment via the cat ladder fixed in the compartment, and carry out a thorough inspection of the compartment interior. Ensure that all safety precautions are taken as per Supplier’s Operating manual

7. Undertaken remedial work when necessary. Water inside the compartment may be removed with the bilge pump facility.

8. After completion of the inspection renew the manhole seal and reinstall the cover. Make sure that the bolts are tightened properly to re-assuring a watertight closure between buoy body and manhole cover.

9. Any paint damage shall be reported and shall be painted at the earliest.

� Buoy Body and Deckhouse The access doors to the deckhouse are to be checked on a two weekly basis, in accordance with the checklists reproduced in this manual. Hinges are to be greased and door seals checked and repaired or replaced. Toolbox hatch hinges and locking device requires little greasing regularly. The deckhouse drains, located inside the deckhouse next to the chain hawse pipes are to be checked and the scuppers cleaned. The ventilation louvers are to be checked and cleaned at regular intervals to maintain a free passage of ventilating air. Inside the buoy body, in way of the overboard piping, the structure and profiles shall be checked yearly for any fatigue cracks, and paint damage that could indicate fatigue cracks. Thickness survey and buoy body/deck house/turret/water tight compartments/ballast tanks shall be carried out every year using UT-meter without damaging the coating (contractor shall keep a working UT-meter with him for doing this activity. Buoy body/deck house (external)/solar panels shall be cleaned with fresh water every month or less. Damage to the topcoat paint may be “touched up” as required with the provided paint if the undercoats remain intact. Should the undercoat paint be damaged, the affected area must be completely retreated in accordance with the paint specification as per SPM Supplier’s manual.

CAUTION

Any serious salt build-up shall be rinsed out.

• Turret Maintenance for the turret is limited to checking the structure for corrosion and repairing damage to the paint system on a regular interval and also checking the cathodic protection.



83

Damage to the topcoat paint may be “touched up” as required with the provided paint if the undercoats remain intact. Should the undercoat paint be damaged, the affected area must be completely retreated in accordance with the paint specification as per SPM Supplier’s manual. The turret seal between the turret and the buoy body is located at the bottom of the buoy body. The seal is below the water level and is not accessible from the top of the buoy. In general the turret seal requires no maintenance.

• SPM Buoy Body Manholes Covers Maintenance requirements for the manhole covers at the buoy compartments involve regular checks for leakage, seal maintenance and lubrication of fixing bolting.In the event of structural damage or leakage in any one or more compartments, the OWNER shall be informed.

• Buoy Trim Change If it is evident that during a maintenance visit or when preparing the SPM buoy for loading operations, that the draft or trim of the CALM buoy system has changed. Sound all buoy compartments for leakage. If any water is detected, following instructions as stipulated at the “Yearly basis” inspection/maintenance instructions. On a Monthly Basis: Sound all buoy compartments for leakage.

• Measure buoys freeboard, trim and record results and compare with as-built data.

• Check condition of sounding pipe O-ring seal. Replace as required.

• Check tightness of manhole covers.

On a Six Monthly Basis:

• Complete all Monthly maintenance tasks listed above. On a Yearly Basis:

• Complete all Monthly and Six Monthlies maintenance tasks listed above.

• Inspect interior of watertight buoy body compartments. Entering the buoy body compartments require special safety precautions Pump out any water from the compartment and carry out any remedial work as required.

• Replace all manhole cover seals.

• After inspection, close the compartment. It is recommended to inspect the buoy body compartments one-by-one and close them immediately after completion of the inspection activities.

CAUTION

Re-installation of manhole covers requires special attention on re-ensuring that the gasket is replaced and that the bolts are tightened properly to establish a watertight connection between buoy body and manhole cover

• Check effectiveness of watertight connection by air leak testing procedure.

Air Leak Test Procedure Apply a slight overpressure of 2 psig to the compartment via the sounding pipe and a pressure gauge/valve the test assembly. Apply a soap solution around the manhole cover seal; hold the pressure for several minutes and check for bubbles indicating leakage through the seal. In case of any air leakage re-tighten the bolts until it is full closed/ watertight.

Pneumatic Winch and Lifting Beam

• Winch The winch is to be decommissioned and to be preserved after completion of use or maintenance activities. The winch is located, within the deckhouse. The winch is to be checked every months for good working order with special attention given to:

• Air line lubrication system

• Air motor

• Gear box



84

• Wire In order to comply with the supplier’s maintenance instructions references are made to the winch MRB. MRB of winch will be provided to successful bidder and all the maintenance as mentioned in MRB shall be done by the contractor. Details of maintenance carried out shall be mentioned in the monthly report.

CAUTION

Air Filter Unit. Preventing that salted air moisture is building up on the inside of the air motor we advise to remove the air filter unit and to seal of the pen ended connection with a suitable plug. Winch wire rope is to be lubricated/ preserved/cleaned with supplier’s recommended lubrication brand every three months.

• Lifting Beam The lifting beam with hoisting eye plate shall be visually inspected for wear and corrosion on a monthly basis. The sheaves shall be treated with BP Energrease LS-EP2 or equivalent on a monthly basis. The wire shall be treated with Shell Malleus Fluid C or equivalent on a monthly basis.

Main Bearing Greasing Special attention should be given to maintenance of the main bearing, as repair or replacement is a major operation. The supplier’s recommended grease should always be used and should never be mixed with

other brands, unless approved by BES. The buoy should be rotated ±40 degrees during the greasing operation. If, during a routine maintenance inspection of the grease system, defective parts are found, they are to be replaced immediately.

CAUTION

To avoid contamination or water ingress, fresh grease must be stored in an on-shore warehouse in a closed container. Under no circumstances should the grease be stored on the SPM system. The next following illustration shows the greasing point in the upper and lower bearing rings. The greasing points are marked UBG and LBG.



85

Figure : Position of Upper and Lower Main Bearing Greasing Points The tension in the bearing stud bolts is to be checked annually in accordance with the procedure outlined in SPM Supplier’s Operating manual. If the inspection shows that any bolt is tensioned to less than 70% of the specified pre-load all bolts are to be checked. Re-tensioned and a further inspection made after six months. If no further loss of pre-load is shown at this inspection, yearly inspections may be reinstated. Immediately after installation, all bolts should be checked and, if necessary, re-tensioned. A subsequent inspection of at least three equally spaced inner and outer bearing ringbolts is to be undertaken after six months of operation. If no loss of pre-load has occurred, the yearly inspection routine may be initiated. To compensate for settling phenomena, it is necessary to inspect and re-tighten the bolts using the same bolt tensioner at the initial assembly. This inspection is to be undertaken no later than 4 weeks after the initial tensioning.

WARNING

When welding on the SPM buoy is required ensure that NO current passes through the main bearing. Four equally spaced earthing cables shall be used to connect the rotating the geostatic part during welding. The buoy body shall be in the locked position. The cables must be connected prior to the commencement of welding, see sketch below. Cable size: four (4) cables of 95 mm

2 L = 2 m



86

Eight (2x4=8) earth bosses are welded next to the main bearing support structure.

Figure: Position of Earthing Cables during Welding The seals are of vital importance as it prevents water and dirt from entering the main bearing. The seal must be checked regularly and very carefully to avoid possible problems with the main bearing at a later stage.

• Grease Sampling

References are also made to the SPM maintenance and operation manual On a yearly basis, grease sample should be taken from the main bearing with the help of required sample collection tools and sent for analysis, with a reference sample of clean, new grease.

A total of twelve grease sampling ports are provided on the buoy – six on the upper bearing ring and six on the lower bearing ring. The points are coded as UBGS and LBGS. An analysis of extruded grease is an effective method of monitoring the condition of the bearing and rollers, the presence of ferrous metals and other particles in the used grease indicating that the wear may be uneven and remedial action required. The results from the grease analysis shall be entered into the maintenance records. Bearing degradation is dependent upon a variety of factors, including the number of rotations, axial wear, and the actual site conditions. It is vital to ensure that the grease samples are not contaminated in any way by dirt, seawater, or foreign particles. Contamination of samples will, inevitably, produce spurious analysis results. Care should be taken when installing a new sample tube to ensure that dirt or foreign particles are not trapped within the tube. Grease sampling and collecting equipment are to be arranged by contractor. Swivel Bearing Greasing



87

Special attention should be given to maintenance of the swivel bearing, as repair or replacement is a major operation. The supplier’s recommended grease should always be used and should never be mixed with

other brands, unless approved by BES. The buoy should be rotated ±40 degrees during the greasing operation. If, during a routine maintenance inspection of the grease system, defective parts are found, they are to be replaced immediately.

CAUTION

To avoid contamination or water ingress, fresh grease must be stored in an on-shore warehouse in a closed container. Under no circumstances should the grease be stored on the SPM system. The next following illustrations show the greasing point in the upper and lower bearing rings. The greasing points are marked UBG and LBG.

Figure: Position of Upper and Lower Swivel Bearing Greasing Points

Electrical System and Navigation Aids



88

The system is to be checked as per check list for good working order with special attention given to:

• The solar panels, cleaning of the surface of the solar panels improves the reception of sunlight and increases the power generation.

• The fog horn.

CAUTION

All personnel on the buoy must be in the possession of ear protection equipment to be used during testing of the fog horn. The provision for testing the fog horn is provided on the fog horn control panel MC-408-932-UA.

• The battery load.

• The marine light and the availability of spare bulbs.

• The load monitoring system

• Visible observation for damage of the cable runs and watertight boxes.

For maintenance instructions, reference should be made to suppliers documentation provided in the Reference manual of Ocean Technical Systems Ltd., Slip ring and Navigation Aids I&O Manual.

• Electrical Components Associated with Electrical Systems

The electrical component, associated with the electrical systems require special maintenance attention. Make sure that the control cabinets and electrical boxes are dry and free of moisture and seawater. The equipment shall be inspected and checked in accordance with the inspection checklist included in the O&M manual of SPM.

• Navigation Equipment

Marine lights shall be visually inspected and subjected to a function test. Carry out a function test by covering the marine lights photocell with a cloth and confirm that the light illuminates. Check that there are spare white marine light bulbs available.

• Safety Equipment The general condition of the life buoys and the fire fighting, safety equipment must be inspected once every three months. During this inspection the function of life buoy light must be checked. Replace the battery if necessary. Safety equipment should be re-certified as & when due for renewal.

CAUTION

Buoy light should be checked for watertight enclosure. Fire Extinguishers shall be serviced/ replaced at regular intervals. Due date is mentioned on fire extinguisher. Contractor shall provide the details of expiry date in Inspection report. Piping System

• General The buoy piping condition is to be checked on a regular basis, as indicated in the Checklists in the Appendices of this manual. Flanges are to be free of seepage and stud bolts tight and free of corrosion. An overall inspection of the piping system is to be undertaken after each offloading/loading. Each inspection shall, ensure that the flanges, valves, flexible joint and swivel are free from leakage, seepage or damage.

• Product Swivel Regular inspections are to be made to detect leakage or oil seepage at the flange connections. Refer to manufacturer’s maintenance data for details. The swivel bearing is to



89

be manually greased via the six grease points/nipples located on the fixed forged flange between the bearing bolts. Swivel bearing manufacturer : Rothe Erde. Grease : BP Energrease LS-EP-2 Quantity : 70 grams/greasing point.

Rotate the buoy ±40 degrees during the greasing operation.One leak detector plug is located on the fixed forged flange. Minor leakage through the leak channel may occur during pumping of product through the swivel. Dismantling of the swivel may be required if the product fluid is found to be leaking during inspection. The swivel seals may be replaced on-site, if the swivel unit is first dismantled. To replace the seals, it is necessary to disconnect the rotating part of the swivel and raise it to obtain the necessary clearance to reach the seal grooves. Should a seal change be required, it will be necessary to shut down the product system, closing the turret valves and ensuring that the system is completely flushed, vented, and certified free of hydrocarbons. The piping may be vented through the vent plugs on top of the buoy piping. Swivel seal replacement should be executed following a approved procedure and should be witnessed by a BES specialist. Contractor shall monitor the level in the leak recuperation before and after discharge of each tanker. This shall be kept in a separate format in addition to pre-berthing/post-berthing checklist and shall be submitted along with monthly report.

• Valves on the Buoy Body and in the Turret All ball valves on the buoy are geared, manually operated, by rotating their hand wheels. The valves are to be operated, OPEN/CLOSE or visa versa and are normally locked in the OPEN position. At least every three months checks for corrosion or oil seepage at the flange connections are to be conducted. Maintenance of valves is to be undertaken in accordance with the supplier’s instructions. References to the valve MRB Supplier Valves & Controls.

Floating Hose Strings and Submarine Hose Strings

• Inspection and Testing of the Floating Hose Strings Inspection and testing of the floating hose strings shall be in accordance with the manufacturer’s recommendations and the OCIMF Guidelines. Periodic inspections of the individual hoses are required to maintain. Hoses that pass all applicable visual, vacuum and pressure testing may be retained in service. Reference should be made to:

• OCIMF “Guidelines for the Handling, Storage, Inspection and Testing of Hoses in the Field, Second Edition, 1995”.

A routine visual inspection of the hose strings is to be made prior to first connection to the tanker manifold. The floating hose strings are to be examined by a service craft/dinghy. Inspections of the hose strings are to comply with the OCIMF & Owner requirements The hoses and winker lights are to be inspected.

• Routinely at least once per month.

• After any period of severe weather.

• After any disconnection/reconnection of the hoses at the tanker mid ship’s manifold.

• After any other external event that might cause damage to the hose strings.

The entire length of the hose strings is to be examined from SPM flange to tanker manifold on the outer surface and at the end couplings and joints for damage or traces of oil seepage. Particular attention is to be given to the first-off-the-buoy hose, the tanker rail hose (including the butterfly valve) and the breakaway coupling. The support chains should be checked for adequate tension.



90

The purpose of the inspections is to detect:

• Signs of damage to the hose or connecting flanges.

• Abrasion, cuts, tears or any other deterioration to the hose outer carcass.

• Signs of leakage from connecting flanges.

• Corrosion of flange nipples or flange bolts or loss of coatings which could result in corrosion.

• Signs of bending/kinking of the hose below the acceptable bend radius.

All inspection results are to be documented. A record of inspection carried out is to be made available to the Owner Report shall be submitted in the specified format along with monthly report. Any damaged hose section is to be reported immediately. Damage found is to be repaired, and if considered critical, the damaged section is to be replaced before any service operation is undertaken. Insignificant damage is to be justified as such to the satisfaction of the Surveyor. Damaged hose sections will be examined for possible repair or tested for future reference. Minor hose repairs such as superficial abrasions outer carcass or replacement of corroded flange bolting may be undertaken with the hose in-situ. Records of repairs are to be kept with the inspection records and made available to the Owner In-situ pressure testing of the hoses should be undertaken approximately every six months/as & when required depending upon local environmental conditions. Testing after periods of severe weather should also be considered. The test is to consist of raising the internal pressure of the hose to 12.5 Kg/cm2, and holding this pressure for a period of three hours. Visual inspection of the hoses should only commence when the pressure is stabilized . Operator should refer to the hose manufacturer’s instructions for the maintenance and inspection recommendations for floating hoses.

• Inspection and Testing of the Submarine Hose

The submarine hoses may be tested in situ at intervals recommended by OCIMF (leak test every six months). As a minimum, testing is to include visual and hydrostatic testing. Inspections of the hose strings are to comply with the requirements of Owner and OCIMF . The hoses are to be inspected by ROV/diver in bad weather

• After completion of every tanker operation and prior to commencement of tanker berthing operation

• After any significant storm.

• After any other external event which might cause damage to the risers. The purpose of the inspection is to detect:

• Major damage to the end flanges/floats/FADs.

• Abrasions, cuts, tears or other deterioration of the outer carcass or the floats.

• Signs of leakage from flanges.

• Corrosion or loss of coating which could lead to corrosion.

• Bending or kinking from the allowable bending radius.

• Displacement from the installed position.

• Excessive marine growth.

• Missing bolts/nuts on the flanges Every three months, hoses are to be cleaned with high pressure jetting system/other suitable equipment for removal of marine growth The entire hose length from SPM flange to the PLEM shall be inspected. The mid section of the hose strings should be checked to ensure that there are no abrasion/contact from the buoy mooring chains. Excessive marine growth on the hose strings shall be removed with soft brushes. The junction between the hose carcass and the hose end nipples should be checked for signs of disbandment, tearing or other damage caused by excessive movement. All inspection results are to be documented and video results of visual surveys maintained. Contractor shall take videography of Subsea hose and umbilical as and when requested by Owner and submit the CD/DVD to Owner for further review. ( 4 copies) Damage found is to be repaired, and if considered critical, the damaged section is to be replaced before any service operation is undertaken. Insignificant damage is to be justified as



91

such to the satisfaction of the Surveyor. Repair to significant carcass damage is possible, but must be undertaken on the surface with special tools. In the event of significant damage, the hose should be replaced and the damaged hose inspected to determine if repair is viable. Minor repairs can be undertaken in situ. Configuration of the under buoy hoses shall be carried out every Month and the results shall be plotted on a graph sheet/CAD with all the relevant data’s as specified by the Engineer in charge. Any discrepancies shall be rectified by adjusting the position of floats/adding new floats. Adjustments shall be verified again to ensure the required configuration.

Inspection and Testing of Hoses on Shore

The requirements for onshore inspection and testing of hoses varies according to location, use and the product carried by the string. In accordance with the current OCIMF guidelines, it is recommended that individual operators establish a statistical database of wear, damage and failure frequency rates by comprehensive testing, including burst testing. Such tests will determine the appropriate retirement criteria and an on-shore testing cycle. Until a database has been established, the hoses should be brought on shore for inspection and testing to the following schedule.

Type of hose Initial test interval

Floating 1 – 3 Years

Submarine 1 – 3 Years

Tanker Rail 6 Months to 1 Year

First off the Buoy 6 Months to 1 Year

In accordance with OCIMF guidelines, the following hose areas should be inspected on shore:

• Hose covers to be cleaned and checked for damage. Where damage has occurred, the extent should be determined and, if minor, repaired. If damage is extensive, hoses should be retired.

• Hoses to be checked for distortions, bulges or longitudinal ridges indicating a damaged carcass. If apparent, damaged areas should be marked and examined under pressure. Hoses with leaking tubes or ruptured reinforcements should be retired.

• All hose fittings should be cleaned and checked for damage and corrosion.

• A visual inspection of the interior hose liner should be made for damage or distortion.

In accordance with the current OCIMF guidelines, the following hose tests should be undertaken on shore:

• Hydrostatic test.

• Electrical Continuity test.

• Vacuum test.

These tests are to be undertaken in accordance with the test procedures outlined in the OCIMF “Guidelines for the Handling, Storage, Inspection and Testing of Hoses in the Field, Second Edition, 1995”. Operator should also refer to the hose manufacturer’s instruction for the maintenance and inspection recommendations for hoses. References are made to MRB. All arrangements and activities necessary for testing hoses On-shore and Off-shore shall be contractor’s responsibility. New hoses/bolts/nuts/gaskets/FADs are in the scope of owner and all other materials required for testing are in the scope of contractor.

• Testing of Retired Hoses

Destruction testing of retired hoses should be given consideration. These tests, either pressure bursting or sectioning will assist in determining hose service life and the required frequency of onshore testing or replacement. Double carcass hoses may be burst to test the



92

effectiveness of the secondary carcass containment and the effectiveness of the primary carcass leak detection system. Retirement decisions are often subjective. Experienced inspection personnel, good record keeping and selective hose burst testing will help in the making decision process.

• Excessive cover and or flotation damage.

• Excessive fitting corrosion.

• Exposed helical wire.

• Fluid leaking from cover/fitting interface.

• Permanent bore deformation e.g. kink, blister or bulges.

• Excessive elongation during pressure test.

• Lining collapse, blister or fluid drawback at fitting nipple end during vacuum test.

• Activated secondary carcass of double carcass hose.

Contractor shall have necessary tools and tackles to conduct burst test. Space will be provided by Owner for conducting the test. Disposal Dispose of hose in a land fill site or as advised by the local waste authority.

WARNING

Do NOT burn flexible hoses!

• Breakaway Coupling The coupling requires periodical maintenance or special inspections when installed in the hose string. Parting gap shall be measured at regular intervals. The unit should, however, be serviced when the hose string is renewed or brought on shore for testing. A full strip-down inspection is recommended after 36 months of service. Following the 36 months inspection/service, the following refurbishment actions are recommended.

• Cleaning

• Re-sealing

• Re-test valve assembly

• Re-set device

• Re-pressure test

• Re-paint assembly

Resetting the coupling after a hose parting or service may be undertaken without specialist tools. Hydro testing procedures and closure test procedures are provided in the manufacturer’s instructions. Procedures for full refurbishment of the coupling are provided in the manufacturer’s spare parts kit. For details of this specific safety equipment, notice to the supplier’s recommendations which are provided in the MRB. Refurbishing of MBC will be done by Owner Maintenance. Contractor shall handover the old MBC at the location specified by Owner and shall take the new MBC from ware house.

• Anchoring System Once a year, a visual inspection shall be made of the anchoring system. Special attention shall be paid to the first two chain shackle links beyond the chain stoppers. To monitor the material wear on these shackles, shackle measures are to be taken when:

• Installation is completed, and

• Once every year. The monitoring of the wear of the chains may give the operator of the SPM buoy facility some indication on the mooring condition. Measurements are to be recorded and kept for reference purpose. Figure given below shows the location where to measure. Every year, condition of one or two anchor chains at touch down portion of sea bed shall be thoroughly checked by the diver.
