英国惠特比渔船整体吊装下水操作

对于船厂来说,其中一大挑战在于如何将造好的船舶放入水中。 近日,沙伦氏(Sarens)在拥有悠久历史的英国渔村惠特比完成了一艘拖网渔船的整体吊装下水操作。



对于一艘长26米、宽8米、高12米、重250吨以上的船来说,这不是一件容易的事情。并且,由于现场空间狭小,精密的工程设计和规划都是必须的。为了进行吊装操作,沙伦氏(Sarens)动员了TC2800-1, 这台吊机起重能力强、稳定性高、且占地面积小,因此被运用进了紧凑的场地内。TC2800-1配置有42米主臂、30米超起背杆和200吨超起配重。
事实上,船体的重量和形状是不规则的,因此团队需要配备专门的装置来分散重量,以便于控制平衡和保证安全提升。 在正式操作的前一天,团队还进行了一次吊装测试,以确保一切将按计划进行。
拖网渔船被吊起后平缓且精准地逆时针旋转,直至水面之上。然后渔船被缓慢地放入水中,安全、成功地完成这次操作。

One of the challenges that shipbuilders face is getting the vessel into the water once building has been completed. Sarens was asked to launch the brand new trawler, Guiding Light, in the historic fishing town of Whitby in the UK.
For a boat 26m long, 8m wide, standing 12m high and weighing over 250T, this is no easy task. Precision engineering and planning was a necessity due to the tight confines of the build yard. To execute the lift Sarens rigged the TC2800-1 as it had the capacity, stability, and its small footprint could be engineered into the tight confines of the yard. The TC2800-1 was rigged with 42m main boom, 30m superlift back-mast, and a 200T superlift counterweight.
The fact that the shape and weight distribution of this type of object are irregular meant that Sarens came armed with specialist equipment designed to disperse the weight, facilitating a controlled, level, and safe lift. The day prior to the installation operation, a test lift of the trawler was preformed to ensure that everything would work as per plan.
Once the full weight of the trawler was taken by the TC2800-1 and the 200T superlift counterweight was active, the trawler was slowly and precisely slewed anti-clockwise until directly over the water. The trawler was slowly lowered in the water, releasing the weight from the crane and completing a safe and successful lift.
