Abstract: 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.
