ABSTRACT

The materials used for offshore aquaculture floating structures in seaweed farming usually have less durability due to oceanic environmental factors. This affects the production of seaweed and increases the cost of production due to the breakdown of the structures. The floating structure of seaweed farming can be improved by choosing a suitable material based on the material properties such as strength, and safe working load. Structural assessment of the components of floating structures for seaweed farming has been investigated. Past materials used by farmers are reviewed to assess suitable material for offshore structures and the hydrostatic analysis is carried out to determine the pressure and dynamics load that the structures can withstand such as wind and current. Finally, reliability analysis using Fault Tree Analysis is conducted to determine the probability of failure of the structural components based on different events. This study has shown that high-molecular polyethylene is a very suitable material for offshore structures.
