Major Works for M/S Technip France

Fabrication of Caisson Gate for Surya Dock of Naval Dockyard Vizag

This caisson gate measuring 23x15x6 Mtrs 320 Ton steel structure with 334 Tons Ballast weight is fabricated on the shore without docking facility. This was an achievement as there were apprehensions about the success of this project till the newly fabricated Caisson gate was tried in the dry dock for its purpose.

The project was done under IRS classification and certification. The modulars were fabricated at our works in Kakinada and transported to Yanam where the complete assembly was undertaken on shore alongside the Godavari River, which joins the sea. The fabrication was completed in record time frame of 12 months. The Gate was towed to Vizag by sea in Horizontal position. The Ballast made of Iron Bricks, Iron scrap billets and Cast Iron blocks totaling to 340 Tons was added manually and the gate was made vertical. Thereafter the complete ballast system piping and air system for de-ballasting was installed and the trials were conducted in Dry Dock. As the gate is required to be under saline environment the gate has been duly protected with adequate sacrificial anodes and underwater paint scheme The Fact that the trials of the gate to check the seating of the Caisson for the Dry dock was successful in the first instance, proved that structure was built with utmost quality standards and professionalism.

Sea Fastening Activity

Sea fastening for all the equipment was undertaken for loading and sea fastening of spools on Barge with necessary arrangements for Cairn India Ltd, , Technip France and UK for their Sub sea activities and, Sea fastening of Christmas Tree for RIL and sea fastening of diving equipment for Deltek and Adsun Offshore.

The major activity has been the sea fastening of spools on Barge Triton for Cairn India Ltd. The activity involved.

The Backup Stanchions were installed by fabricating from ISMB 250 beams and wooden fenders were provided for each stanchion on the Barge. Base Plate of 20mm Plate was used for the footing and welded to the deck
Wooden Dunnage was provided on the Barge as sleepers for each lot of spools being secured.
On Placement of the spools on the Barge, the lashings were arranged
Each lashing consist of 16mm Usha Martin Make wire rope, wire rope clamps and thimbles, Sea linker make 3.75, 4.75, 6.5 and 8 Ton Shackles as er the load requirement and sea linkers make 12” and 18” Turn Buckles.

Sea Fastening for Technip :

The sea fastening activity was undertaken for M/S Technip France for their 3 campaigns with RIL during the years 2007 to 2011.

The main activity for sea fastening involved

Pre fabrication of gussets for the main equipment at work shop.
Pre fabrication of shims in Work shop
Preparation of lashing material for sea fastening
The lashing consisted of Approx 21 Mtr of wire rope, 04 Nos turn buckles, 8 Nos shackles of 3.75/4.75 Ton capacity depending on the tonnage of equipment and required number of thimbles and wire rope clamps.
One end of the lashing was fastened to the equipment and the other end was fastened to the deck or nearest available securing point.
The Pad plates were of 100x 100 mm size and were fabricated from 14mm MS Plate. The Pad plates were welded on to the deck after removal of wooden sheeting from the deck.
Test certificates/material certificates were provided for wire ropes. Shackles and Turn Buckles,

Sea Fastening for Diving Equipment for Cairn India Ltd.

We have been undertaking the sea fastening activity for diving operations for last 15 to 20 years for our client Cairn India When ever the diving operations are planned, the sea fastening of the diving equipment like compressors, cylinder racks, Diving containers, A brackets, etc., were undertake by us.
