Gulliver Heavy Lift Vessel, Belgium
Gulliver is a new self-propelled, DP II heavy-lift vessel being constructed by Royal IHC for DEME's subsidiary, Scaldis Salvage and Marine Contractors.
The vessel is being built at the Hong Qiang shipyard near Shanghai. It was previously referred to as Rambiz 4000, but was renamed Gulliver in April 2016.
The ship can assist with decommissioning activities, as well as the installation of offshore infrastructure and wind farms in deep water for the oil and gas industry.
An agreement was signed in January 2015 to finalise the construction and delivery of the vessel, and the keel-laying ceremony took place in February 2016.
The lifting equipment will be installed at Huisman's facility in Xiamen. Delivery of the vessel is scheduled for early 2017.
Gulliver design details
The heavy-lift vessel has been designed by Vuyk Engineering Rotterdam, a subsidiary of Royal IHC.
Optimised for offshore heavy-lift missions, the vessel will be 108m long with a moulded breadth and depth of 49m and 8m, respectively. It will have an operating draft of 4.9m and gross tonnage of 22,400t.
The vessel will offer accommodation for 78 persons, very small aperture terminal (VSAT) internet, voice over IP (VoIP) facilities, and a helideck.
The ship will be classified under Lloyd's Register of shipping notation 100A1, Crane Ship, LA, IWS, LMC, UMS, DP(AA) and CAC 3.
Equipment on-board Gulliver
The ship will be equipped with two Huisman cranes on its port and starboard. With a lifting capacity of 2,000t each, the cranes will provide the ship with a hoisting capacity of 4,000t.
The wave height of the cranes will be 1.5m, and their maximum lift height will be 78.5m above the deck. The distance between crane booms will be 34.3m.
The two cranes will also be movable up to a distance of 25m, allowing the deck to be used for cargo transportation.
Eight mooring winches will be installed at the bow and stern of the vessel. The winches will be capable of handling 44mm and 58mm anchor chains.
The vessel will feature an additional carrying capacity of 3,000t, as well as a moon pool for a remotely-operated vehicle (ROV), which will be used in the inspection of installation works on the seabed.
The ship will be classified as Ship Right (ACS (B)) as its ballast tank will be coated with anti-corrosion materials. Its fuel tank capacity will be 1,342m³, while its water ballast capacity will be 11,316m³.
The vessel will store 935m³ of fresh water and include a watermarker capable of holding 20m³ a day.
The heavy-lift vessel will be propelled by four azimuth thrusters. The aft and forward thrusters will offer a propulsion power of 1,720kW and 1,505kW, respectively.
The thrusters and DP II system remove the need for anchoring while conducting installations in deep water. The propulsion system will provide a transit speed of 7kt.
