A novel concept of a floating wind-solar-aquaculture (WSA) system, combining multiple megawatt (MW) vertical-axis wind turbines (VAWTs) and solar arrays with a floating steel fish-farming cage, is presented. Meanwhile, the offshore solar energy is also drawing more and more attention from the academic communities.

Subsequently, coupled dynamic analysis is performed for the production risers using the dynamic analysis software OrcaFlex.Results and discussion evaluate the impact of the dynamic behavior and stress of the production risers as well as the cost.ĪBSTRACT Both offshore wind energy and offshore aquaculture are developing rapidly and moving into deeper waters to acquire better resources. Hydrodynamic data such as added mass and damping coefficients, forces and motion Response Amplitude Operators (RAOs) of the Spar are first obtained using the simulation software MOSES through uncoupled analysis. The production risers are modeled on Spar floater subjected to environmental conditions in the Gulf of Mexico. The basic cost comparison is carried out briefly to assess their suitability in deep waters.

This paper serves to analyze and compare the dynamic behavior between different kinds of production risers (Steel Catenary Risers, Flexible Dynamic Risers, and Free Standing Hybrid Risers) and their impact on the floating production platform (floater) in an actual field environment. A key factor is a dynamic behavior as it may lead to increased loads on the platform (floater), especially under severe environmental conditions.

offshore projects planning and execution (2)Ībstract As the oil and gas industry moves towards deep waters in search of hydrocarbon, production risers are unequivocally affected by it.

Publication type: Conference Proceedings (inc. Discussions will compare and evaluate mooring analysis results of three different types of spar platforms (Classic, Truss, and Cell). Coupled dynamic analysis will then be carried out for the spar platforms and their mooring configuration using dynamic analysis software Orcaflex. Hydrodynamic coefficients and RAOs (Response Amplitude Operators) will first be obtained using hydrostatic and hydrodynamics analysis software MOSES. Spar platforms tested will be subjected to actual environment conditions in the Gulf of Mexico. This paper compares and analyses the motion response of the three different types of spar platforms in an actual field environment as well as the effects of mooring lines. For spar platforms to operate efficiently in deep water, it is important for the platform to have superior station keeping abilities. Each generation of the spar is designed to improve the functionality of the previous one with a reduction in cost.

Spar platforms have been improved over the years, from the first conventional classic spars to an improved variant, the truss spars and then the recently developed cell spar. Since the installation of the very first spar platform, spars have become increasingly popular due to its high stability. Alternative links are provided below where available.
