Heerema Marine Contractors (HMC), based in Leiden, The Netherlands, has released a few more details of the US$1 billion deepwater construction vessel it announced last December.
It will enable HMC to operate in remote areas and ultra deepwater. Once the vessel enters the market in 2010, says HMC, it will secure construction capacity for at least another three decades. The conceptual design was prepared in-house by Heerema Marine Contractors: The new vessel will be 220 meters long, 88 meters wide and 44 meters in depth. To cut travel time between projects, it will have a maximum speed of 20 knots: up to four times the speed of HMC's current deepwater construction vessels. There will be facilities for 550 people, upgradeable to 750.
Payload is 25,000 tonnes and the power generation capacity will be of 75 MW. The Dynamic Positioning Station keeping system will be of NMD Class III.
The dual crane capacity of 15,000 t will enable HMC to continue installing the largest and heaviest fixed and floating structures to date. The new J-Lay tower and deepwater lowering construction means that HMC can install pipelines and structures from 200 - 3,500 meters water depth with a maximum of 32 inches O.D. The tension capacity will be 2,000 t: this is double the capacity of HMC's Balder.
HMC says that the new vessel's design and speed, will make offshore construction in the Arctic feasible. The placement of the cranes, the J-Lay tower and other installation equipment, as well as the structural quality of the hull and thrusters, are well suited for the Arctic.
This summer will see the long-lead ordering of key components, such as the cranes and J-Lay Tower. Options are currently being discussed with possible suppliers.
