BOKOR TOPSIDE INSTALLATION: SURGICAL PRECISION
boskalis at a glance ANNUAL REPORT 2020 – BOSKALIS
The semi-submersible heavy transport vessel Forte completed an incredibly precise float-over installation offshore the Malaysian part of Borneo in August 2020. The accurate positioning of the 11,238-ton Bokor CPP-A topside was the climax of a major project involving colleagues from various disciplines at Boskalis.
The preparations included fitting out the Forte with a dynamic positioning (DP2) system that automatically controls the position and course of the vessel with thrusters and an advanced control system. The system can be used not only in joystick mode but also in auto position and auto track modes. All three methods were used during the different phases of the float-over to achieve the required accuracy. The specific conditions on the Bokor project, and particularly the limited space for maneuvering the Forte at the offshore location, were the immediate reasons for installing the DP2 system. “Without DP2, tugs and anchor handlers would have been required to anchor and position the Forte. In this case with dynamic positioning we could execute the operation safer, faster and more efficient,” explains Ronald Goetheer, operations director Heavy Marine Transport.
