During the long-term service condition, mooring line of deep-water floating platform may fail due to various reasons, such as overloading caused by an accidental condition or performance deterioration. Therefore, safety under transient responses process should be evaluated in advance, during design phase. A series time-domain numerical simulations for evaluating changes a Floating Production St...

Fuzzy clustering is an important problem which is the subject of active research in several real-world applications. Fuzzy c-means (FCM) algorithm is one of the most popular fuzzy clustering techniques because it is efficient,...

this paper presents an efficient hybrid method, namely fuzzy particleswarm optimization (fpso) and fuzzy c-means (fcm) algorithms, to solve the fuzzyclustering problem, especially for large sizes. when the problem becomes large, thefcm algorithm may result in uneven distribution of data, making it difficult to findan optimal solution in reasonable amount of time. the pso algorithm does find ago...

Feature selection is the process of removing the irrelevant features from the datasets and fuzzy clustering of microarray data are the most fascinating machine learning techniques in the real world. The main objective of this paper is selecting the independent components of the microarray data using Independent Component Analysis in order to improve the effectiveness and accuracy of the Fuzzy P...

The extraction of oil and gas from deep water is one of the most important challenges of the oil and gas industry today. FPSO is one of the leading platforms for deep waters. This study discussed the performance of FPSO deck modules under loads exerted on the hull of the ship. Modeling of the studied module was executed by SACS software and the effect of support using neoprene in the function o...

This paper presents a novel improved fuzzy particle swarm optimization (IFPSO) algorithm to the intelligent identification and control of a dynamic system. The proposed algorithm estimates optimally the parameters of system and controller by minimizing the mean of squared errors. The particle swarm optimization is enhanced intelligently by using a fuzzy inertia weight to rationally balance the ...

This paper present a new computationally efficient improved stochastic algorithm for solving multi-area DC Optimal Power Flow (DC-OPF) in interconnected power systems. This algorithm is based on the combined application of Fuzzy Logic strategy incorporated in Particle Swarm Optimization (PSO) algorithm, hence termed as Fuzzy PSO (FPSO). Multi-area DC-OPF calculations determine optimum generatio...

In this paper, a new side-by-side mooring bay designed by Keppel Offshore & Marine Technology Centre is investigated, and its global performance and dynamic stability are compared against those of the traditional SPM-mooring system. The multi-body systems include SPM buoy with a turntable and mooring system, a VLCC FPSO, oil tanker, and the hawsers/fenders and yokes between them. A time-domain ...
