ABSTRACT:

Macro-algae farming have become one of the natural resources which are economically important. Macro alage are used as food in many Asian countries, and extracts for use as food additives (gelling agent, preservative etc.) and in other industries (textiles, pharmaceuticals, biomass energy etc.). The existing cultivation systems for macro-algae are not environmentally, socially and economically sustainable. Lack of suitable platform for large scale cultivation and potential coastline disturbance necessitates the need to develop novel deployment technology for deep and opens water cultivation. Macro-algae are useful biomaterial for food, food supplement, gels, solar cell, clean animal feeds, biomass energy, pharmaceutical, fracking product. To avoid mooring system failure, selecting an appropriate breaking strength and limit state for mooring lines is necessary, this paper describe multiple interacting mooring system design that account for forces and environmental loadings on the system. The paper describe evaluation of optimum mooring performance in wave, wind induced current loadings on mooring components, analysis of anchor, buoy, riser elements and compensator sinker that are involved in the multiple mooring system dynamics are presented. The paper also discuss establishment of appropriate safety factors and coefficient for the design of very large offshore aquaculture floating structure.
