A Damen Trailing Suction Hopper Dredger (TSHD) 1000 was launched at the Krasnoye Sormovo Shipyard on January 29, 2016. The TSHD, named ‘Sommers’, is a lead vessel of a series of three TSHD 1000s being built for Rosmorport in Moscow, Russia.
A contract signed in April, 2014 between Rosmorport and Krasnoye Sormovo Shipyard was needed in order to schedule the TSHDs for delivery in 2016.

The TSHD 1000 vessels will feature a package of dredging solutions, including dumping through bottom doors or a pre-dumping door and pumping ashore through a bow coupling unit as well as rain bowing.
All three of the vessels are expected to be tailored to meet client requirements and to operate in local climatic conditions.
The vessels will perform maintenance dredging in the basins and access channels of the ports of Ust-Luga, Big Port St. Petersburg and Tuapse.
