Shipbroker Fearnley Offshore Supply reports that Norwegian shipowner Siem Industries has placed an order with Mawei Shipyard, a subsidiary of Fujian Shipbuilding Industry Group, for two offshore support and construction vessels (OSCVs). Delivery is expected in 2029 and 2030, though the construction cost of the new vessels has not been disclosed. According to Clarksons data, the order includes options for two additional vessels.
Reports indicate that Norway’s Sirius Design & Integration is responsible for the conceptual design and complete basic design of this OSCV class. Based on Sirius’s construction support vessel design, the OSCVs will have an overall length of 144 meters and prioritize operational flexibility, energy efficiency, and future-proof systems; they will be equipped with a 400-ton crane.
Recently, Mawei Shipyard has secured contracts for several new vessels in the offshore engineering sector. In addition to the 2+2 OSCVs from Siem Industries, Union Vega Offshore—a joint venture formed by the British shipowner Union Maritime and the Norwegian shipowner Vega Maritime—has placed an order with the shipyard for 2+4 platform supply vessels (PSVs), with delivery expected to begin in 2028.
Designed by Breeze Ship Design, this PSV measures 84 meters in overall length and features a battery-hybrid propulsion system, a moon pool, 900 square meters of deck space, and accommodation for 44 crew members. The design includes provisions for the future installation of a 50-ton Active Heave Compensation (AHC) crane, thereby enhancing its operational flexibility and capabilities.
The official website states that Mawei Shipyard, formerly known as the Fujian Mawei Shipyard, was founded in 1866 under the name Fujian Shipbuilding Bureau and was China’s first mechanized shipbuilder. In 2016, Mawei Shipyard relocated to Culu Island in Lianjiang. The facility covers an area of approximately 1,060 mu and features a medium-sized offshore engineering dry dock (280 meters long, 82 meters wide, and 13.5 meters deep), equipped with one 700-ton gantry crane, three outfitting piers, and 1,326 meters of berthing line.
