Numerous Acts of Parliament and Statutory Instruments which apply to Floating Production, Storage and Offloading (FPSO) developments in the United Kingdom Continental Shelf (UKCS), covering a wide range of issues including health, technical safety, work place safety, lifting operations, environmental protection and pollution prevention and control, are described. A comprehensive study of system...

Multimodal optimization problems pose a great challenge of locating multiple optima simultaneously in the search space to the particle swarm optimization (PSO) community. In this paper, the motion principle of particles in PSO is extended by using the near-neighbor effect in mechanical theory, which is a universal phenomenon in nature and society. In the proposed near-neighbor effect based forc...

This paper presents a numerical investigation on the harmonic structure of hydrodynamic forces fixed and simplified representative floating production, storage offloading (FPSO) vessel hull under dispersive phase-focused wave groups. The high-fidelity model utilizes two-phase flow solver in open-source toolbox OpenFOAM. A series cases were computed using model, where effects steepness, bow diam...

The standard Particle Swarm Optimization (PSO) algorithm is a novel evolutionary algorithm in which each particle studies its own previous best solution and the group’s previous best to optimize problems. One problem exists in PSO is its tendency of trapping into local optima. In this paper, a multiple swarms technique(FMSO) based on fast particle swarm optimization(FPSO) algorithm is proposed ...

In this study, an efficient method is introduced to predict the stability of soil-structure interaction (SSI) system subject to earthquake loads. In the procedure of the nonlinear dynamic analysis, a number of structures collapse and then lose their stability. The prediction of failure probability is considered as stability criterion. In order to achieve this purpose, a modified adaptive neuro ...

FPSOs are useful in newly established offshore oil regions where there is no pipeline infrastructure in place, or in remote locations where building a pipeline is cost-prohibitive. In this study, hydrodynamic analysis of FPSO is inquired based Boundary Element Method (BEM) and wave forces/moments, added mass and damping coefficients of degrees of freedom are obtained by AQWA software. FPSO moor...

This paper presents a hybrid unsupervised clustering algorithm, referred to as the Rough Fuzzy C-Means (RFCM) algorithm and Particle Swarm Optimization (PSO). The PSO algorithm features high quality of searching in the nearoptimum. At the same time, in RFCM, the concept of lower and upper approximation can deal with uncertainty, vagueness and indiscernibility in cluster relations while the memb...

Group technology (GT) is a useful way to increase productivity with high quality in cellular manufacturing systems (CMSs), in which cell formation (CF) is a key step in the GT philosophy. When boundaries between groups are fuzzy, fuzzy clustering has been successfully adapted to solve the CF problem; however, it may result uneven distribution of parts/machines where the problem becomes larger. ...

To achieve the maximum power from wind in variable-speed regions of turbines (WTs), a suitable control signal should be applied to pitch angle blades. However, available uncertainty modeling WTs complicates calculations these signals. cope with this problem, an optimal controller is suitable, such as particle swarm optimization (PSO). improve performance controller, fractional order PSO (FPSO) ...

This study explores the impact of Paris Agreement on determinants firm-level capital structure decisions listed contractor-owned Floating Production Storage and Offloading (FPSO) companies in oil gas (O&G) industry from 2000 to 2019. The identified various financing structures between FPSO due their individual institutional characteristics. Tangibility, profitability, market-to-book (growth), s...
