Appraisal of Mega Float - Floating Offshore Remote Terminal (FORT) on Catenary Mooring for Deep Water

With the development of offshore fishing and deep sea exploitation intensifies, floating offshore remote terminal (FORT) which having many advantages can better adapt to the complicated environment of deep sea in numerous offshore platform. Due to the hull likely to to resonance phenomenon, FORT has more intense motion compared to other hull form types. Therefore, the main challenge of FORT in the deep sea operation is to design effective mooring system. This paper introduced the dynamic response by utilizing the computational effort associated with time-domain simulation of single anchor leg mooring (SALM). The influenced or the effect of significant wave height (SWH) over the structure is discussed. It is shown that a comparison of different SWH value in terms of their stability properties is sufficient and adequate; relative merit is assessed through comparison of full systems that have been designed to minimum cost, and to common performance specifications. It is found that single point or catenary systems, can outperform both static and dynamic solutions at the preliminary stage. Moreover, the results indicated that the position ability and mooring strength of SALM system whose intermediate material is studless chain of catenary mooring system on the premise that satisfies API specification at the same time.

Mega Floats: Floating Offshore Remote Terminal (FORT) towards Sustainability Life Cycle Assessment

The life cycle model of Mega Float: Floating offshore fishing terminal (FORT) for deep sea fishing industry is presented in this paper. FORT is a totally new concept of a mega float for deep sea fishing application. It is aimed at increasing productivity through reducing travelling time to fishing ground by providing critical support services such as loading and unloading and minor maintenance and repair of boat and equipment at sea close to the fishing ground. The immediate concern is surely on its life cycle cost and techno-economic viability. The system is huge and remotely located far offshore and hence the element of sustainability and environmental friendliness and safety are some of the major investment issues. Immediate cost consideration includes the relatively high initial/acquisition cost and operation and maintenance costs and the intention is to at least self-sufficient by generation income from the services offered. Therefore, hybrid algorithm of cash flow and life cost cycle is applied in FORT implementation. The new derivation of the mathematical model for FORT application is developed to life cycle assessment principle [1-3]. The algorithm requires data that could be best produced based on forecast demand and projected cost. For ease of use the lengthy algorithm will be presented in a computer-based package.
