Heerema signs LOI with Jurong Shipyard for semi-submersible crane vesselVessel & ROV News // March 30, 2015
Heerema Offshore Services has signed a Letter of Intent regarding the engineering and construction of a semi-submersible crane vessel (NSCV) with Jurong Shipyard Pte Ltd, part of Sembcorp Marine.
Heerema Offshore Services will equip the vessel with two cranes each of 10,000 tonnes lifting capacity. The cranes, designed and under construction by Huisman Equipment, will provide heavy lifting capacity to install and remove offshore facilities and can also be utilized for the installation of subsea structures, foundations, moorings, and floating structures in deep water.
The NSCV will be self-propelled with a transit speed of 10 knots, with power generated by means of dual fuel engines – MGO and LNG. Stationkeeping is by means of dynamic positioning (DP3) or a mooring system. With a length of 214m and a breadth of 97.5m the NSCV will be the world’s largest crane vessel.
In a statement, Heerema said the introduction of the NSCV "will enable HMC to meet customers’ demand for lifting capacity beyond what it can currently offer," and noted that the ship's large, reinforced work deck will increase efficiency when installing or removing offshore facilities.
Jan-Pieter Klaver, CEO of Heerema Marine Contractors, said: “Our Letter of Intent with Jurong Shipyard represents the next critical step in our plans to introduce the NSCV to the market.
"The fact that we decided to press on with our plans in these times of low oil prices, shows our belief in the offshore oil and gas industry."
Heerema Marine Contractors currently already owns four of the world’s largest crane vessels: SSCV Thialf, DCV Balder, SSCV Hermod, and DCV Aegir as well as a range of anchor handling tugs and transportation barges including the H-851, the world’s largest barge.
