Holding OOS International Group, with its headquarters in Serooskerke, confirms it has recently signed a fixed contract for the engineering and construction of two new build Semi-Submersible Crane Vessels (SSCV) with China Merchant Industry Holdings (a fully owned subsidiary of the China Merchant Group).
“The order of the ‘OOS Serooskerke’ and the ‘OOS Walcheren’ is a result of an innovative and unstoppable Dutch spirit,” says Léon Overdulve, owner of OOS International. “We took a quantum leap within the Oil-, Gas- and Wind Industry.”
OOS will equip its two new SSCV’s with two heavy lift cranes, with a total dual lifting capacity of 4400T per vessel. The heavy lifting and service cranes will be provided by Huisman Equipment, which can be utilized for the (de)commissioning of subsea structures, foundations, moorings, floating and heavy lift platforms for offshore wind structures in deep water.
A total of 600T can be heave compensated installed or removed at 3000 meters water depth.
The two SSCV’s offer a new turnkey solution for the offshore market having both hotel and heavy lift capability simultaneously. In between projects they will have a transit speed up to 12 Knots.
These unique technical and commercial benefits have been efficiently proven with the first SSCV unit named ‘OOS Gretha’, presently working for Petrobras, in Brazil.
The SSCV’s will be equipped with a state-of-the-art enhanced dynamic positioning class 3 system from Kongsberg. Kongsberg will also provide system switchboards, frequency converters, automation, navigation & DP systems, radio and satellite communications, networking and on board entertainment, safety technology and monitoring components such as the advanced helideck system.
The SSCV’s will also be equipped with STX-MAN diesel engines and Thrustmaster thrusters fitted with a condition monitoring system.
In addition, the units will provide hotel services for 750 people in mainly single and twin cabins built to the highest standards following ABS habitability requirements. These hotel services will be utilized during the preparation work prior to the execution of actual heavy lifting projects.
“Today’s oil and gas economics does not hold us back,” says Leon Overdulve. “The fact that we decided to continue with our plans by introducing these niche products in the current market situation, shows our strong long-term commitment, as well our trust in this great novel concept.”
The engineering and construction phase is estimated to be completed in Q2 2019 for the first SSCV (‘OOS Serooskerke’) and Q3 for the second SSCV (‘OOS Walcheren’).
