Damen launched 2000 m³ ice class hopper dredger for Russian customer Rosmorport


First Trailing Suction Hopper Dredger in 30 years

This month Damen Shipyards Group launched ice class Trailing Suction Hopper Dredgers TSHD 2000 for Russian Port Agency FSUE “Rosmorport”.
Song Thu Corporation shipyard in Da Nang, Vietnam is building the Damen TSHD 2000 under Russian Maritime Register of Shipping (RS). Following delivery, the 2,000 m³ Severnaya Dvina will maintain navigational depths and provide safe shipping in the Arkhangelsk Seaport basin and approaches.

The launching ceremony on 9 November was attended by the Consul-General of the Russian Federation in Da Nang Andrey Brovarets, FSUE “Rosmorport” General Director Andrey Tarasenko, representatives from RMRS, Damen and from Damen's business cooperation Song Thu Corporation shipyard.

FSUE “Rosmorport” awarded the contract to Damen following an open tender in 2013. Project Manager Harrold van Vliet says Damen tailored the TSHD 2000 design to meet the high specifications required to operate the vessels 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 vessel is designed for efficient operation and ease of maintenance, including a Ø600 mm trailing pipe and hydraulic winches, a low pressure Damen inboard dredge pump for the most efficient hopper loading process, telescopic overflow and 5 rod-actuated bottom doors.

   • Hopper capacity: 2,000 m3
   • Trailing suction pipe diameter: Ø600 mm
