Damen launches ice-class TSHD for Rosmorport

The Song Thu Corporation shipyard in Da Nang, Vietnam is building the vessel under Russian Maritime Register of Shipping (RMRS). Following delivery, the 2,000m³ TSHD will maintain navigation depths and provide safe shipping in the Arkhangelsk Seaport basin and approaches.
FSUE Rosmorport awarded the contract to Damen following an open tender in 2013. Damen’s project manager Harrold van Vliet said the shipyard had tailored the TSHD 2000 design to meet the high specifications required to operate in the severe weather conditions of Russia’s northern region, with air temperatures ranging from -30°C to +40°C. “The Severnaya Dvina has a reinforced bow with ICE 1 notation so it can continue dredging in waters approaching freezing point, and then relocate with icebreaker support. During the engineering phase we held regular design review meetings with the client to ensure we delivered exactly the capability they required.”
Fitted with a complete Damen Dredging Equipment dredge and instrumentation package, the 80.35m-long and 16.2-wide vessel is designed for efficient operation and ease of maintenance, including a 600mm trailing pipe and hydraulic winches, a low pressure Damen inboard dredge pump for the efficient hopper loading, telescopic overflow and five rod-actuated bottom doors. Its dredging draught is 5.1m and accommodation is offered for a crew of twelve.
