In the last decades, many efforts have been made to solve multimodal optimization problems using Particle Swarm Optimization (PSO). To produce good results, these PSO algorithms need to specify some niching parameters to define the local neighborhood. In this paper, our motivation is to propose the novel neighborhood structures that remove undesirable niching parameters without sacrificing perf...

This study entailed the estimation of wind loads performed using computational fluid dynamics (CFD) simulations for four typical offshore vessels and a Floating Production, Storage, Offloading (FPSO) shuttle tanker in side-by-side configuration on offloading. For all vessels, under heading condition, meshes were used to carry out verification validation (V&V) check numerical uncertainty. Th...

Nowadays with increasing production and exploration activities offshore, the FPSO system has been widely adopted globally because of its unique design adaptability to these offshore environmental conditions. This research project aims provide station-keeping characteristics an in West African region, by analysing spread mooring for multiple load cases, different offset, draught conditions loads...

Recent studies were carried out to determine the variation in safety factors (between the applied loading and the capacity) of FPSOs currently operating in the UK Sector of the Central North Sea, and designed using either a class rule type approach or a more advanced hydrodynamic – FE type approach. Results from these studies seem to indicate that the safety factor in both cases is similar, sin...

Floating, Production, Storage and Offloading “FPSO” have become a popular choice since 1980s for marginal and fast-track developments where subsea pipeline is not an economic or feasible solution for export. Field development usually starts with a concept selection procedure which is constituted from a sequence of multi-disciplinary decision making tasks. As limited data is availabl...

In offshore locations with harsh environment, the operation of cylindrical floating production storage and offloading (FPSO) becomes more challenging. Poor motion performance can severely affect structural safety, mooring system's strength riser's operation. Therefore, interceptor plate installation above heaveplate is proposed in order to improve FPSO's especially heave responses. A set 1:100 ...

Real-time monitoring of the mooring safety floating structures is great significance to their production operations. A deep learning model proposed here, based on long short-term memory (LSTM) artificial neural network. Firstly, numerical simulation carried out with single-point system a Floating Production Storage and Offloading (FPSO) as training data LSTM. Then LSTM performed. Finally, takin...
