[1]GSP is the general contractor within the offshore EPIC (engineering, procurement, installation & commissioning) project for Türkiye Petrolleri Anonim Ortaklığı (TPAO), the national oil and gas company of Turkey.

The installation operation was successfully completed at 00.20 a.m., the topside being safely positioned on the 101 meters steel jacket, in Akcakoca perimeter, offshore Turkey, in the north western part of the Black Sea.

The double deck topside was transported to the location onboard GSP Bigfoot 2. The platform installation was performed with the help of GSP Neptun, the 1800 tons heavy lift crane moored to GSP Bigfoot 3, the spacer barge barge P4 and GSP Bigfoot 2, the semisubmersible barge. After removing the welded seafastening, the steel double deck platform was lifted from the semisubmersible barge GSP Bigfoot 2 and GSP Neptun lowered the topside and stab cones in the jacket piles. The topside will be welded to the jacket, according to the procedures.

GSP has mobilized a complex fleet of technical and support vessels, including: GSP Bigfoot 3 (accommodation and work barge for offshore operations), GSP Neptun (heavy lift crane, 1800 tones), GSP Bigfoot 2 (semi-submersible heavy lift transport barge), GSP Queen (ROV support vessel), GSP Licorn (supply ship), Agat (AHT), P4 flat-top ocean going transport barge, and Aran.

The 101 meters steel jacket installation was followed by the pile installation with: foundation pile and conductor installation, grouting operation (the main and the skirt piles being grouted to the jacket), pile cut-off, and miscellaneous completion activities. These activities were performed according to the project schedule.

The top side installation operation will be followed by the completion activities.
