1.0 INTRODUCTION

1.1 GENERAL:-

The Regional works Commander, Coast Guard region (NW), Gandhinagar

intended to construct Coast guard station at vadinar, Gujarat. The Construction of

Coast guard Jetty at OOT Vadinar is to be carried out as a deposit work by Kandla

Port Trust. Kandla Port Trust has accepted the proposal for the constructing of a

Jetty length 175 m along with approach road to the jetty of length 275 m. IIT

Madras, Chennai agreed to prepare Detailed Project Report (DPR) and Feasibility

study for the project. The site visit was made on 16th and 17th June 2014 with the

officials of Indian Coast Guard and Kandla Port Trust. On basis of the

requirements and specification of Indian Coast Guard –Vadinar the Detailed

Project Report for construction of Coast guard Jetty at OOT Vadinar is prepared.

1.2 SITE LOCATION & PORT LIMIT :

Vadinar is small coastal town located in Jamnagar district of the state

of Gujarat, India. The offshore oil terminal of the Kandla Port Trust (K. P. T.) is

located in Vadinar and contributes in a large way to the total earnings of this

major port. Vadinar is now notable due to the presence of two refineries which are

close by - one promoted by Reliance Industries and the other by Essar Oil Ltd.

A salt production unit is located in Vadinar. The famous Narara Island, which is

part of Marine National Park, is situated 7 kilometers away from town. Two

single-buoy moorings (SBM) of the Kandla Port Trust offshore oil terminal of

the Indian Oil Corporation are located at this port along with a similar buoy of the

Essar refinery.

2.0 SITE CONDITION

2.1 Metrological Data

In 1988, India Meteorological Department introduced the 16 parameter power

regression and parametric models and started issuing forecasts for the southwest

monsoon rainfall over the country as a whole. IMD introduced new statistical

forecasting system based on ensemble technique for the south-west monsoon

season (June to September) rainfall over the country as a whole. The local area

forecast station is situated at Rajkot which takes care of all kind of Meteorological

functions.

2.1.1 CLIMATE

Vadinar has a hot semi-arid climate, there are three defined seasons. The summer

season lasts from March to May and is extremely hot, humid, but dry. Rainy

season with extremely erratic monsoonal rainfall that averages around 630

millimeters. Tropical cyclones sometimes affects the region during this period.

The winter season is from October to February remains hot during the day but has

negligible rainfall, low humidity and cool nights to be by far the most comfortable

time of year.

2.2 OCEANAGRAPHIC DATA

Oceanographic data of vadinar is obtained by several studies conducted by Indian

Oceanographic Data Center in and around coast of Jamnagar, Okha and Dwaraka. The

data’s are classified as Sea water temperature, salinity tides, wind, wave, current, sea bed

level and they are as follows

2.2.1 SEA WATER TEMPERATURE

Actual sea surface water temperatures close to shore can vary by several degrees

compared with these open water averages. This is especially true after heavy rain, close

to river mouths or after long periods of strong offshore winds. Offshore winds cause

colder deep water to replace surface water that has been warmed by the sun. The average

mean sea water temperature is 280 C at vadinar coast.

The main activity of harbour tug is providing assistance to vessels entering /

leaving the harbour, turning of the vessel in the harbour and the berthing /

unberthing operations. The coast guard vessels are capable of self-berthing and

there is no need of tugs for berthing activity. However if required K.P.T shall

provide tugs on rental basis / free of cost depending on its administrative policies.

9.2 Pilot-cum-Survey Boats:

Pilot boats transfer pilots to and from the incoming / outgoing vessels. It is

recommended to provide one all weather type pilot launcher. The pilot launch

should be a twin screw with 15 to 20m overall length and of steel construction. The

speed range shall be 15-20 knots. This pilot launch will be provided with survey

equipment and it can be used for hydrographic surveys and for buoy lights

maintenance. It is observed that K.P.T has already deployed Pilot-cum-Survey

Boats &it is recommended to use those boats, if necessary one Pilot-cum-Survey

Boats shall be engaged specifically for Coast guard if only the traffic for existing

K.P.T berth is high.


[Type text]

9.3 Channel Marker Buoys

10.0 Conclusion and Recommendations:-

The Proposal for Construction of Jetty at off Shore oil terminal, vadinar has been

finalized as 175x 13m landing jetty and 275x9m approach jetty. The location of jetty

shall been on a reclaimed earthen structure of 60x 100m. The parking area shall

primarily serve as waiting bay and movement will be regulated into operational area.

The administrative building, port building and other amenities shall be in the

prescribed reclaimed area limits. This Detailed Project Report cum feasibility report

has been prepared on the basis of the data furnished by the client, observations on site

visit, considering IS codal requirements and client requirements, the construction of

Coast Guard Jetty and it’s allied infrastructure are feasible. The proposal and Cost

estimation proposed by IIT Madras are only for project feasibility and for obtaining

project grants. For execution of work a detailed design should be carried out, and the

cost estimate shall be based on the detailed design. IIT Madras strongly recommends

to conduct a fresh soil investigation near the proposed jetty and reclamation area at

the time of detailed design since the soil investigation data available are very old. A

fresh bathymetry shall also conducted at the approach channel and near the berthing

areas.
