Ulstein Design for Heerema
After having developed the concept and basic design for Heerema’s new monohull vessel, Ulstein Group´s Dutch based design company, Ulstein Sea of Solutions (USOS), has now also been awarded the further engineering of the vessel with the selected shipyard, DSME of South Korea.
In February 2010, USOS was contracted by Heerema to design their new deepwater construction vessel, for which an LOI was signed between Heerema and DSME mid July 2010. On 24 August the LOI was turned into a building contract with DSME for the design, construction, testing, commisioning and delivery of this impressive vessel, a record breaking time for development and award of such a vessel.
The self propelled DP3 Deepwater Construction Vessel is a customized version of the Ulstein SOC 5000 vessel design. The Heerema vessel features a revolving heavy lift capability of 4,000 tonnes, deepwater lowering equipment up to 3,500 metres and a pipelay tower for J-lay and Reel-lay operations via a moonpool. The hull configuration is specially designed for fast transit speeds and optimum motion characteristics in operation.
The vessel is DP3-class equipped with 2 x 6500 kW and 4 x 3200 kW thrusters allowing for a transit speed of 12-14 knots.
Following the contract award to DSME by Heerema, USOS signed a contract with DSME on 13 September for further vessel engineering and integration of the mission equipment designed by Huisman. “The work will be executed by a dedicated project office in Vlaardingen where engineers from DSME and Ulstein Sea of Solutions work closely together. The central location of the Ulstein Sea of Solutions office, close to Heerema and Huisman, is important to have good communication and flow of information required to shorten the timeline in the early phase of the construction of such a vessel,” said Van Leeuwen.
Main dimensions of the vessel:
Length, o.a 693.9 ft
Beam, moulded 151.5 ft
Depth, moulded 52.8 ft
Operating draught 36 ft
Service speed 12-14 kn
Installed power 6 x 7,370 kW
