Harvey Gulf International Marine has accepted the delivery of its second, large-capacity, multi-purpose support vessel (MPSV).
The 103.6-metre-long vessel, Harvey Blue-Sea, is a "best in class" Jones Act-qualified vessel designed to safely perform field development activities.
Harvey Gulf officials said Harvey Blue-Sea can perform subsea installations and removals, inspection, repair and floatel services. It can be equipped to lay umbilicals and cables and perform well-intervention and hydrate remediation operations.
She is equipped with a 250-tonne knuckle boom and active heave compensated crane equipped with 4,000 metres of wire.
The crane's winch is below deck, expanding its lifting capacity and enabling loads of 107 metric tons to be delivered to water depths of 3650 metres.
Harvey Blue-Sea has 150 berths, all in one- or two-person rooms, 1,200 square metres of deck space, and a seven-metre diameter moon pool.
It also has a S61 (heavy) helideck and meets ABS DP2, SPS Code and MLC 2006 certification requirements.
Harvey Gulf now owns and operates the two largest US-flag construction vessels in the Gulf of Mexico, having taken delivery of the sister vessel Harvey Sub-Sea in July 2017.
