APPENDIX – D


BUOYANCY MATERIAL

The boat is to be fitted with sufficient buoyancy material to enable the satisfactory swamp test to be undertaken. The quantity and arrangement of Buoyancy proposed shall be forwarded to IHQ-MoD(N) for approval. Material

The buoyancy materials shall be of polystyrene (expanded with a substantially closed cell structure) and shall have the following physical properties: Density : Not more than 0.08 x 10 Kg/m3

Water absorption : Increase in weight of raw material (i.e. not encapsulated) after complete

immersion in water to a depth of 1.2 Metre (4 feet) for 24 hours not to exceed

25% measured on a block 76mm x 305mm x 305mm (3in x 12in x 12in).

Shaping and Forming :

The buoyancy material may be pre-formed in moulds or may be made up from pieces of the material

stuck together, however if difficulty is found in providing the reserve of buoyancy these methods may

be augmented by “in situ” foaming in the boats structure, subject to prior approval of IHQ-MoD(N).

Blocks made from pieces of the material are to be stuck together with General purpose Epoxide Adhesive.

The surfaces of each block of material and the exposed surfaces of the in situ foaming shall be given two spray coats of Waterproofing Compound.

After fitting the material, all block and “in situ” foaming shall be protected by either a GRP laminate not less than 2.5 mm thick or by 6 mm plywood with fastenings not more than 75 mm apart. The plywood shall comply with APPENDIX – A.

The fitting arrangements shall be such that the blocks will remain in place and contribute to buoyancy in the event of the boat being swamped. There shall be a clear distance of at least 75 mm between the material and exhaust pipe and other sources of heat. In these positions the material shall be secured with aluminium straps. Because of its higher melting point a polyurethane based material is only preferred in these positions.

PROCEDURES FOR TESTS AND TRIALS

1. Following inspections/trials/tests would be conducted:-

(a) In Line Inspections (ILI) (b) Technical Tests and Trials (c) Pre-Dispatch Inspections (PDI) (d) Joint Receipt Inspections (JRI)

2. In Line Inspections. This would be carried out by the Naval Overseer at the builders premises during

construction of the boats and involve scrutiny of the methodology of construction, raw materials and

dimensional checks.

3. Builders Responsibilities

3.1 The builder shall prepare and forward to the Naval Inspecting Authority, a programme of trials before

commencement of trials.

3.2 The builder shall arrange for the attendance of Reps. of their subcontractors during the trials.

3.3 The Builder shall lift or slip each boat after completion of all tests to enable examination of underwater

hull and fittings.

3.4 The Builder shall be responsible for the provision of any spare parts, tools, equipment, etc. required

during trials. Builder shall be responsible for replacement of any item/equipment damaged or found to be

defective during trials without prejudice to any of the spare gear provided. The Builder shall also make good at

his own expense, all defects found in the construction, fittings, machinery and electrical installations before the

boat is accepted.

4. Sequence of Tests & Trials

4.1 Unless prior IHQ-MoD(N) approval is obtained, the tests and trials shall be carried out in the same

sequence as they are described in the following paragraphs. Wherever possible, the inclining experiment, shall

immediately follow the weighing test.

5. Swamp Test This test shall be carried out only for the first boat of the particular contract.

5.1 The boat is to be fitted with sufficient buoyancy material to enable the satisfactory swamp test to be

undertaken. The quantity and arrangement of buoyancy proposed shall be forwarded to NHQ for approval. The

object of this test is to ensure that the boat will remain afloat, stable, upright at normal trim and with at least 10%

reserve of buoyancy after it has been filled with water. This ensures that there is a positive freeboard all round

the boat when it is swamped, thus enabling it to be pumped or baled out.




YEAR 2011

ISSUE 4



5.2 Preparation

(a) The boat shall be as complete as possible, but any structure/equipment that would suffer from immersion in water during test shall not be fitted but represented by ballast of impervious material eg. cast iron pigs. This ballast shall be arranged to represent the combined weight and CG of the missing items in the boat.

(b) The total weight to be compensated is made up of the weights in air of items which would be above water with gunwales completely awash, and the weights in water of items which would be below water in this condition.

(c) The compensating ballast will usually be immersed during the test and allowance must be made for its affective loss of weight in water. Suitable density corrections shall be made depending on the water used to swamp the boat.

(d) The weight of an item in water can be readily determined if the item is regularly shaped. If it is not, a reasonable estimate of its watertight volume should be made, based on measurement of its principal dimension from which an approximate loss of weight in water can be found.

(e) The boat shall be weighed just prior to the swamp test, and the weight recorded. The compensating ballast should then be placed abroad and arranged so that its CG is in the correct position, as calculated.

5.3 Test

(a) The ballasted boat shall be placed in a sufficient depth of water allowing it to sink to the gunwales without grounding. It shall be held on slack lines, and if the water is deep, precautions shall be taken to prevent the boat from sinking completely.

(b) The drafts forward and aft, and the density of water shall be recorded prior to swamping.

(c) The boat shall then be swamped until the gunwales are awash, drafts recorded. Finally, the ballast shall be added progressively until it is equal to 10% of the total weight of the boat and drafts recorded. The boats should maintain positive freeboard in this condition.

5.4 Report of Swamp Test

As soon as possible, after the test, the boat builder shall forward the following detailed report to

IHQ-MoD(N) through the Naval Overseer.

(a) The weight of boat is prepared for swamp test (without compensating ballast).

(b) Calculation of weights of compensating ballast and position of its CG.

(c) Draughts of boat just prior to test (with compensating ballast aboard).




YEAR 2011

ISSUE 4



(d) Draughts of boat with addition of 10% of weight of boat as ballast.

(e) SG of water in which swamp test was conducted.

(f) SG of water used to swamp the boat.

(g) An amount of total buoyancy provided in the boat by means of buoyancy tanks in cubic meters/feet.

5.5 If during the course of the test, serious doubts arise as to the adequacy of boat's buoyancy or stability,

the matter shall be reported immediately to IHQ-MoD(N). If when swamped, the boat has excessive

heel or trim, or is unstable, does not have atleast 10% reserve of buoyancy, the matter shall be

investigated and corrective measures taken. The swamp test shall be repeated until satisfactory results

are achieved.

6. Drop Test All the boats shall be subjected to this test. The completed boat with compensating

ballast for full complement, machinery and fuel shall be drop tested, as per the requirements of SOLAS

1983, by dropping the boat in water from a height of 3 meters. After the drop test the boat shall not uffer

from any residual deformation/defect.

7. Impact Test All the boats shall be subjected to this test. The completed boat with compensating

ballast for full complement, machinery and fuel shall be subjected to an impact test as per the

requirements of SOLAS 1983. For this test, the boat shall be subjected to a lateral impact against a

steel impact the boat shall not suffer from any residual deformation/defects.

8. Deflection Test All the boats shall be subjected to this test. The completed boat with compensating

ballast for full complement, machinery and fuel shall be subjected to a deflection test as per the

requirements of SOLAS 1983. For this test, the boat shall be supported at the ends and a load equal to

twice the mass of the boat shall be placed at the centre. The boat shall not have any residual deflection

on removal of the load.

9. Weighing Test All boats of the contract shall be weighed using a certified weigh-bridge. The boat

shall be complete in all respect except that no crew, fuel or stores shall be onboard. Once weighed no

further items or fittings shall be placed onboard until all tests and trials are completed. The report shall

include list of items/fittings not on boat at the time of test and shall quote their individual weights.

10. Inclining Experiment

10.1 The first boat of the contract shall be taken up for Inclining experiment. The boat shall be as complete

as possible. The boat shall be in the same condition as weighed in the weighing test with all fuel tanks

completely empty. Any loose item/equipment shall be properly secured during the test. Procedure of

calculating weight and position of compensating ballast is explained at para 20.

10.2 The inclining ballast shall be divided into four equal parts, the total amount being regulated, so that no

appreciable change in water-plane area occurs when the boat is heeled.




YEAR 2011

ISSUE 4



10.3 The minimum length of pendulum shall be 1.5m. Mean density of water in which the boat is floating

shall be measured and before the experiment begins, the drafts forward and aft shall be recorded.

10.4 During the experiment, a careful watch shall be kept to ensure that the mooring lines are slack and are

not in any way affecting the behavior of the boat.

10.5 The Builder shall prepare a report as placed at para 21 of the experiment and forward the same to NHQ

duly authenticated by the Naval Overseer.

11. Floatation Test All the boats shall be subjected to this test. The boat shall remain afloat after

loaded with weights representing equipment and full life saving load of men with all complements. The

free board in this condition shall be measured and forwarded to IHQ MoD(N).

11.1 The boat shall remain afloat for a minimum period of two hours and leakages if any are to be rectified

by the Builder.

12. Lowering/Hoisting Trials All the boats shall be subjected to this test. Lowering/Hoisting trials

with full equipment/ stores/ complement of boat shall be carried out by both Bridle and Davit lifting

arrangements. Final acceptance of the boat is subject to satisfactory performance of lifting arrangements when

hoisted onboard the ship designated (ultimate consignee) by Naval Headquarters both from single arm & twin
