SCHIEDAM, Netherlands -- Tideway and Royal Boskalis Westminster have awarded contracts to Huisman for the design, build, and commissioning of stone dumping systems. The systems are capable of accurately dumping stones in water depths of up to 2,000 m (6,562 ft).
The systems will consist of a gimballing tower and hang-off module, preventing buckling of the self supporting pipe string as a result of vessel motions. From a pipe storage facility, the pipes are transported by a crane to a buffer position and subsequently inserted into the tower with an automated pipe loading system.
In the tower a headclamp and rollerboxes provide smooth handling and coupling of the pipe sections, attaching each pipe section with high speed.
Delivery of the systems is planned for the second half of 2010 and start of 2011.
Huisman will also deliver skiddable and heave compensated umbilical winches, moonpool hatches, ROV cursor frames, hydraulic/nitrogen systems, and four control cabins.
