Offshore

In view of the sizes and weights of the equipment involved in the construction of an offshore facility, the offshore industry demands highest levels of engineering, detailed planning and best equipment and manpower for the transportation and installation of critical equipment. The load outs of offshore equipment like Jackets and Decks requires detailed understanding of the heavy transport, ballasting & deballasting of the barges, mooring, tidal variations and stability calculations.

Nature of Work : Load Out of 2 Nos. of Offshore Jackets – VSEC measuing 54.5m x 30.77m x 34.51m and weighing 2559 MT and VSEB measuring 60m x 29.68m x 33.75m and weighing 2230 MT for L&T Modular Fabrication Facility, Chennai for the Additional Development of Vasai East Project (ADVEP) of ONGC.

 

Project Highlight : Freight Wings was awarded the engineering and loadout contract for the 2 Jackets of Additional Development of Vasai East Project of ONGC at Mumbai Hight. Due to the location at which the jackets were fabricated, VSEC jacket had to be maneuvered on Trailers in a zig zag way steering the jacket clear of the VSEB jacket in a semi circular path and then straight march onto the RO RO jetty. The two loadouts were executed within a gap of 25 days. The scope of work included the load out engineering including the mooring analysis, ballasting deballasting calculations, stability analysis and the entire loadout operation. Both the loadouts were carried out safely as per the schedule.

Nature Of Work : Load out of Offshore Modules including a 67.1m x 47.3m x 45.3m Jacket weighing 3200MT for GSPC’S PLQP Project with EIL as Project Management Consultants (PMC) at Kattupalli (Chennai). The scope of work also included the Ballasting, deballasting and Mooring of the barge.

 

Project Highlight : Working in a Greenfield yard, we were responsible for mooring of the 400 class barge using our customized system of mooring winches and power packs. We were also involved in the detailing of the Load out arrangements including transport girders besides advising the client on the ground strengthening for this massive movement. Besides mooring calculations, we also gave the client ballast, deballast calculations for the floating load out of the jacket and its accessories including a 1250MT flare tripod and a 148 M long Flare bridge. The ballasting & deballasting of the barge during the Load Out was done by us, using our high capacity self priming deck pumps and all the Loadouts were carried out safely, as per the client’s schedule, on our computer controlled SPMT’s.

Nature of Work : Load Out of Offshore Modules including a 49m x 26m x 26m Topside Deck   weighing 2200MT for GSPC’S DDW1 Project with EIL as Project Management Consultants(PMC) at Kattupalli, Chennai. The scope of work also included the Ballasting, deballasting and Mooring of the barge

 

Project Highlight : Since this was the first load out to be performed at this facility, we designed the mooring arrangement of the barge with our hydraulic mooring winches. We were responsible for giving ground strength requirements to the client. We also performed ballasting & deballasting of the Loadout Barge using our specialized pumps and detailed engineering. The project was carried out as per Client’s schedule and to their satisfaction.
