![]() from the seabed is referred to as a dredger ship or more commonly a dredger.ĭredgers are of great importance, as they serve the purpose of ensuring the necessary safe bottom clearance for safer voyages. In a more general sense, a ship equipped with an excavation tool that is capable of weeding off depositions such as sand, gravel, sediments, etc. The first discussions about a newbuild dredger took place in 2015 and the ship was delivered at the end of 2018.A marine vessel fitted with a device(s) to scrap or suck the sediment deposition over a sea bed is known as a dredger (The device used for excavation and scraping of the sea bed is called the Dredge). The conclusion reached in 2015 is that a refit will become too complicated. The technical feasibility turned out to be a major challenge, partly due to the space in the engine room, the positioning of the LNG tank and the welding and cutting on deck while dredging on LNG. Conoship participated in the feasibility study ‘Dredging on LNG’ (TKI Gas) as early as 2013 and then, together with Van der Kamp, set up the feasibility study ‘Refit TSHD Rhine Delta to LNG Dual Fuel/electric installation’. The process of building this ship has had an intensive preliminary phase. 300 m3 and 4 Dual Fuel main generator sets, will be maintenance dredging in ports like Rotterdam, but also the mining of sand and gravel. The main purpose of this dredger, that incorporates an LNG tank of approx. This innovative LNG fueled Trailing Suction Hopper Dredger with a capacity of 5,500 m3 for dredging company Van der Kamp BV from Zwolle, The Netherlands is built in 2017/2018.
