Title
(EN) Preloading to reduce loads and save steel on topsides and grillage of catamaran systems
(ZH) 用于在双体船系统的干舷和格排上减少负载及节省钢材的预加载
Abstract
(EN)
The present invention reduces loads and saves steel on topsides and grillage of a catamaran system by creating an upward, lifting force from a barge to the topsides to offset a sagging bending moment of the self-weight on the topsides during transportation. The present invention can reduce the span of the supports on the topsides on the catamaran float-over barges and move the reaction forces toward inner edges of the float-over barges. The upward force can cause a reduction of stress on the topsides' and grillage's members caused during the topside offloading and transportation. The stress reduction can result in the members withstanding the additional dynamic load caused by a catamaran system without increasing member sizes adequate for an offloading operation. The reduction results in a significant savings, given the size of a typical topsides for a Spar hull or other offshore structure.

本发明通过产生从驳船(115)到干舷的向上提升力以在运输期间偏移干舷上自重的下垂弯矩从而在双体船系统(100)的干舷(110)和格排(125)减少负载和节省钢。本发明可减少双体船浮托式驳船上的干舷上的支架的跨距,并且将反作用力朝向浮托式驳船的内部边缘移动。向上的力可导致在干舷卸载和运输期间所引起的干舷构件和格排构件上的应力减小。在没有增加足以用于卸载操作的构件尺寸的情况下,应力减小可导致构件经得起由双体船系统所引起的附加动载荷。若给定用于Spar船体或其它离岸结构的典型干舷的尺寸,则该减小使得显著节省费用。
