Rockwater 2 Fact Sheet


Information gathered from Halliburton Subsea


The Rockwater 2 is a multi-purpose diving support vessel built in 1984 for diving, construction and intervention work. In 1999, the vessel was lengthened, side sponsons added and many vessel systems upgraded.
The vessel fittings include a 150t/250t crane (offshore/harbour capacities) on the port side and a 100t crane sited on the starboard side of the main deck. A 4-point mooring system is serviced by winches at the bow and stern of the vessel.
Diving services are supported by an 18 man saturation diving spread and a 16 man hyperbaric lifeboat. The diesel electric plant includes 5 main generators, 4 in one engine room and 1 in a separate engine room. One emergency/harbour diesel generator is also located in a separate room.
Dynamic Positioning (DP) is provided by the Kongsberg SDP 512 computer control system, with dual control computers and a third monitoring computer. These receive information from a range of reference and sensor systems, and control the functioning of the thrusters; three tunnel thrusters at the bow and two azimuth thrusters aft.
Fully air-conditioned accommodation is available for 106 people. Rockwater 2 is equipped with a helideck certified to take a S61N. The helideck is protected by a foam monitor and fixed water monitors.
