Modified Cutter Suction Dredger receives new classification
Damen has delivered a customised cutter suction dredger for a Van Oord project in the Caspian Sea. This CSD650-18 M Cutter Suction Dredger, named the Ural River, is the first of its kind in the 650-range and was acquired in January 2015 with a substantial list of modifications. The vessel, with its 700kW cutting power, is a modular dredger with a total of 8 pontoons: a main pontoon with the engine room and controls, side pontoons for storage/bunkering of fuel and water and flotation and a spud carriage pontoon. The list of customised items included all the winches, safety provisions (plans, MOB, tags etc.), the internal management system, the connection points and the fire-fighting installation in the engine room. All crew service members and warranty engineers received BOSIET (Basic Offshore Safety Induction and Emergency Training) and helicopter escape training. Certification documentation needed to be well defined as the classification of the dredger was significant. Generally this type of dredger is used in sheltered areas but in this case a specialised team of Van Oord, Bureau Veritas and Damen received approval for an update to the design, permitting coastal classification, allowing the vessel to operate further from shore. The Ural River’s dismountable design allowed for road and sea transport to the Caspian Sea, bringing with it its own challenges such as permits, licenses and a long transport period for spare parts.
