AUGUST 4, 2016 — In what it calls a "quantum leap within the offshore & heavy lift industry," Serooskerke, Netherlands, headquartered Holding OOS International Group B.V. yesterday confirmed that it has signed a fixed contract for the engineering and construction of two new semi-submersible heavy lift & accommodation vessels —OOS Serooskerke and OOS Walcheren— with China Merchant Industry Holdings.
They will be built at the CMHI (Jiangsu) shipyard in Haimen, China, and will be similar to the company's 138 m x 81 m DP3 Semi-submersible Crane/Construction/ Accommodation Vessel OOS Gretha, delivered by CIMC Raffles in 2012.
"Today's Oil & Gas economic situation does not hold us back," said Leon Overdulve, founder and owner of Holding OOS International Group BV. "The fact that we decided to continue with our plans by introducing niche products to the Oil & Gas/Wind Industry in the current market situation, shows our strong long-term commitment, as well our trust in this great novel concept."
OOS will equip the new SSCVs with two Huisman heavy lift cranes, with a total dual lifting capacity of 4,400 tons per vessel.
The cranes can be utilized for the (de) commissioning of subsea structures, foundations, moorings, floating and heavy lift platforms for offshore wind structures in deep water.
Between projects the vessels will have a transit speed up to 12 knots.
They will provide hotel services for 750 people, in mainly single and twin cabin. These hotel services will be utilized during the preparation work prior to the execution of actual heavy lifting projects
OOS says that by proving both hotel and heavy lift capability simultaneously, the vessels offer a new turnkey solution for the oil & gas/offshore wind market and that their technical and commercial benefits have been demonstrated by its first SSCV, OOS Gretha, presently working for Petrobras, in Brazil.
The SSCVs will be equipped with a state-of-the-art enhanced dynamic positioning class 3 (DP3) 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.
Separately, Kongsberg Maritime reported today that it had signed EPC contracts with China Merchants Heavy Industries (CMHI) relati worth more than NOK 520 million, covering deliveries to the two vessels.
Kongsberg Maritime together with its wholly owned subsidiary Kongsberg Maritime Engineering (KME) will execute the project.
KME will provide all engineering, procurement and project management while Kongsberg Maritime will supply a "Full picture system" delivery.
The Kongsberg contracts include supply and integration of the electrical, telecom and integrated control systems, project management, interface management and engineering services at all stages. In addition, a significant technology scope of supply includes; switchboards, frequency converters, automation, navigation & DP systems, radio and satellite communications, networking and on board entertainment, safety technology and monitoring systems such as the advanced environmental monitoring system.
The engineering and construction phase is estimated to be three years for the first vessel with the delivery of the second vessel coming nine months later."
We are very pleased that we can supply a tailor made EIT (Electrical, Instrument and Telecom) solution for the shipyard and owner with a large scope of both in-house and procured technology," says Egil Haugsdal, President, Kongsberg Maritime.
