{"id":91,"count":14,"description":"A Trailing Suction Hopper Dredger is a self-propelled vessel, used for\u00a0maintaining or deepening waterways,\u00a0or to dredge sands\u00a0to replenisch beaches or to be used for construction purposes on land, thereby using powerful\u00a0pumps and deploying one or two suction pipes fitted with a draghead,\u00a0which are\u00a0lowered onto the seabed, whilst moving slowly forward. The dredged materials are held in its hopper,\u00a0to be discharged at the intended\u00a0location, often many miles away from the dredging area, 1) through its bottom-doors, mounted in the keel of the vessel, 2) to pump these ashore, sometimes over distances of more than one\u00a0kilometer, by means of a quick coupling mechanism, usually\u00a0mounted at the bow of the vessel, or 3) spraying the material\u00a0over a short distance, also known as rainbowing.","link":"https:\/\/www.vlmaritime.com\/nl\/product-category\/dredgers-nl\/hopper-dredgers-nl\/","name":"Hopper Dredgers","slug":"hopper-dredgers-nl","taxonomy":"product_cat","parent":47,"meta":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.9 -
