Some type of vessels are at sea for a special purpose
Their primary task is drilling for oil, laying cables, creating artificial islands, laying cables, installing wind turbines, or to perform different types of rock installation an so on. These ships should be able to sail the sea as efficiently and safely as possible, but should also be able to be keep position or to follow a certain track while on the job.
The typical full hull form of these type of vessels, the use of thrusters and nozzled propellers and the requirements on dynamic positioning and workability require a special approach with respect to design, calculations and model tests. Issues which are usually addressed are flow separation, dynamic positioning capability, thruster-thruster and thruster-hull interaction, moonpool oscillations, loads on legs of jack-up vessels, seakeeping behaviour at transit and zero speed and dynamic tracking.
Subsea rock installation vessel, suitable for installation of a wide range of rock sizes through a fall pipe at the side of the vessel. With a deadweight of 14,000t, a length of 154 metres and a beam of 28 metres, the vessel can operate in water depths of more than 600 metres. There is accommodation for 60 people.
