  • Patent number: 9469957
    Abstract: 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: Grant
    Filed: February 23, 2014
    Date of Patent: October 18, 2016
    Assignees: China National Offshore Oil Corp., China Offshore Oil Engineering Co.
