CMHI to build two vessels for OOS

CMHIChinese shipyard China Merchants Heavy Industry (CMHI) won a contract to build two new semisubmersible combined accommodation and crane vessels for Dutch firm Overdulve Offshore Services (OOS).

The OOS Serooskerke (named after a village in the Netherlands) and OOS Walcheren (a former Dutch island, now part of the mainland, and where Serooskerke village is) will be capable of lifting and positioning with two 2200-tonne capacity cranes, with combined 4400-tonne capacity, using Huisman Equipment supplied cranes. The cranes will be used for decommissioning subsea structures, foundations, moorings, floating and heavy lift platforms for offshore wind structures in deep water.

The vessels will each provide and provide beds for 750 people on board, and will be DP-3 system and able to perform subsea lifting in up to 3000m water depth, says OOS.

The engineering and construction phase is estimated to be completed in Q2 2019 for the first SSCV (OOS Serooskerke) and Q3 2019 for the second SSCV (OOS Walcheren)

“The achievement of this contract with CMIH Shipyard will provide the end-client with a bespoke solution for the oil and gas /wind market, resulting in significant cost reductions. Today’s oil and gas economics does not hold us back,” says Leon Overdulve, founder and owner of Holding OOS International Group.

“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 currently has two semisubmersible accommodation crane vessels, the OOS Gretha and OOS Prometheus, built at CIMC Raffles in 2012 and 2013. OOS Gretha, which is working offshore Brazil for Petrobras, has 618 beds and two 1800-tonne cranes, and OOS Prometheus has 400 beds and a 1100-tonne crane.

CMHI recently awarded Kongsberg Maritime contracts worth NOK 520 million for work on 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 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 and 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 and the delivery of the second vessel will be nine months later.
