Publication number: 20150240439Abstract: A new pneumatic load transfer and shock absorbing system is disclosed. The pneumatic system includes a layer of air-bags to perform two basic functions during a floatover installation operation: 1) lifting the platform deck from the support to create additional air gaps at the mating surfaces, and the heave motions of the lifted platform deck may be reduced; 2) performing as a shock absorbing device with variable vertical stiffness easily controlled by the air-bag internal air pressure during the mating operation and the separation operation.Type: ApplicationFiled: February 23, 2014Publication date: August 27, 2015Applicants: China Offshore Oil Engineering Co., Ltd., China National Offshore Oil Corp.Inventors: James Lee, Wen Jun Zhong, Han Jun Yin, Xin Zhong Li, Mo Fan, Xiao Hong Zhou, Yuan Lang Cai, Xiao Long Yang, Xiao Wei Zhang, Liang Wang

Publication number: 20150093202Abstract: A new jacket design method is disclosed, especially for deepwater water heavy jacket applications. The method utilizes a special type of air bags, called Ship Launching Air Bags (SLAB), to provide low cost temporary buoyancy used for jacket installation purpose only. A designer only needs to satisfy the jacket stiffness for the resistance of environmental and gravity loads without the consideration of jacket reserve buoyancy. The required jacket reserve buoyancy could be increased with the utilization of temporally attached SLABs during the jacket installation.Type: ApplicationFiled: October 1, 2013Publication date: April 2, 2015Applicants: China Offshore Oil Engineering Co., Ltd, China National Offshore Oil CorpInventors: James Lee, Han Jun Yin, Zhi Gang Li, Wen Jun Zhong, Xin Zhong Li, Jin Lin Hou, Mo Fan, Xu Jia, Yu Jie Yuan, Huai Zhou Huang
