Gibdock secured its first dry docking contract from Technip. Wellservicer, a multi-role diving support vessel with subsea lift capability, has undergone an intensive and relatively complex class renewal docking at the Gibraltar yard, and has been delivered back to Technip, ready for work.
Gibdock staff undertook Technip’s Integrated Safe System of Work (ISSoW) program, a course specific to the marine sector exemplifying the standards set for the owner’s fleet. All manual workers engaged in the project passed level 1, with Gibdock management undertaking level 3.
The 111.4m long, 9158gt DP-class 3 Wellservicer arrived at Gibdock on May 6 and was undocked on June 17. After several days of afloat repairs and sea trials, she returned to the yard for mobilization work, before leaving for her next assignment in Canada.
The main scope of work included an extensive overhaul of the ship’s three tunnel thrusters and three azimuthing thrusters, which were removed to the yard’s workshops, disassembled and put through a rigorous maintenance program before rebuilding. Gibdock engineers worked in close collaboration with Technip’s supplier, Rolls Royce. It also included removal of the two small deck cranes and their replacement with two brand new five ton capacity units. This required deck plate modification, including work to under deck stiffeners.
Other tasks included an upgrade to the fire line system, which involved fitting new pipework, and the erection of a significant amount of scaffolding. This was required in order to safely gain access to the helideck, and to carry out necessary works to the under deck supports.
