Jack-Deck for FPSO Module Installation

Technip has developed a new installation concept called the “Jack-Deck” which enables installation of topsides onto an FPSO hull in one or two “Integrated Modules” with weights of up to circa 21,000t each (See Figure 1). This installation method facilitates extensive pre-commissioning and commissioning of the modules at their construction yard. It considerably reduces the onshore hook-up and integration work required on top of the FPSO hull deck. Consequently, the overall FPSO construction schedule and cost are significantly reduced. This paper describes the “Jack-Deck” installation method and discusses the consequences on topsides layout and structural design. It also highlights the main benefits of the system.
