Multifaceted design
Designed to operate both in deep and shallow waters – preserving depth in the main waterway between the Gulf of Gdansk, through the Vistula Lagoon to the Elbląg River – the vessel’s challenging design specification includes an air draft of 9.1 meters and the ability to work in very shallow waters with a minimum dredging depth of 5 meters.
The vessel’s wheelhouse and accommodation were placed at the front to ensure it could pass the Trasa Unii Europejskiej bridge. And due to weather conditions in the area, the vessel was designed to withstand temperatures of at least -10°C while dredging, and -20°C while in transport.
C-Job collaborated closely with Holland Marine Technologies, who supplied the dredging equipment, to agree interfaces and integrate the equipment to strict tolerances.
The Ursa’s design and details were completed to tight deadlines, with different engineering phases performed simultaneously which required precise project management and communication between C-Job, the client, suppliers and shipyard. The TSHD has a capacity of 950 m3, is 62.75 meters long, and has two propellers. It features one suction drag arm with a maximum dredging depth of 18 meters.
