Floating Regasification Terminals - Selection Marinisation of Regasification Equipment for Offshore Use

摘要

This paper presents an overview of existing regasification technologies, discusses key marinisation issues and theirrnadaptability and design for offshore use as well as consideration of the environmental impact. To assist in the development of arnhigh level CAPEX critical for early project feasibility studies, key cost drivers associated with marinisation will also berndiscussed.rnIn the context of rising global energy demand and lack of space for shore-based regasification terminals, the use of floatingrnregasification developments are on the rise. The success of floating regasification terminals lies in the design of thernregasification and process equipment, which needs to maintain high availability at the required regasification rate whilst underrnthe influence of offshore environments and ship motions. Furthermore, for floating regasification facilities that arernpermanently moored offshore, the regasification equipment will also need to withstand the harshest marine environments. Thernregasification equipment therefore needs to be designed for offshore operations and survivability.rnMarinisation is a common approach used in the design of offshore floating production facilities (FPSOs) and extending thisrnconcept to floating regasification involves adapting existing and proven shore/land based regasification equipment for thernoffshore environment. In addition to ensuring operability, requirements for high availability influence the equipment layoutrnand placement on deck to minimize repair downtimes.rnThis paper is targeted towards projects or developments centered around permanently moored, offshore floating regasificationrnterminals. The number of such terminals currently planned or in development is on the rise in South East Asian countriesrnwhere the main purpose is to provide base load regasification where gas demand is constant and set to increase on a year-byyearrnbasis. In contrast with the Atlantic floating regasification terminals, where only seasonal demands are required to be met,rna base load terminal calls for a stricter requirement in terms of availability and offshore survivability, and hence the approachrnto marinisation for base load terminals is different to that for seasonal load terminals.
