AB  - The prospect of aquaculture is likely to be
more located far offshore, generating lesser conflict and
higher nutrient assimilation capacity. Aquaculture
structure also potentially available for ecotourism. This
article presents the design of steel structure offshore fish
cage, not only for fish farming but also for ecotourism.
The design is proposed based on the oil and gas standard
and code practice. To ensure the operational safety of
both mariculture and ecotourism, the structural strength
and mooring design needs to comply with the applicable
standards. There are several sides of buoyancy frame.
Each consists of K-Brace steel structure. These buoyancy
frames form the floater shape. The shape is then equipped
with adequate supporting structures on the topside to
provide strength for aquaculture operation and ecotourism
activities. The mooring system used is a rectangular array
system and the study of fairlead position variation is
performed. The initial design of the structural and
mooring system of novel structure that able to
accommodate offshore aquaculture farming as well as
ecotourism is proposed. With these combined functions,
the designed structure is adequate to withstand the loads
exerted. Further works should be performed to check the
fatigue performance of the structure.
