An essential aspect of Catenary Anchor Leg Moorings (CALM) buoy structures are the components hydrodynamics like waves, underwater current, and wind. In this study, numerical investigations on CALM were carried out. Firstly, motion study free-floating was conducted in ANSYS AQWA. Then an Orcaflex-coupled model system with submarine hoses Lazy-S configuration, presented. It attached to six moori...

Recent design challenges in ocean observations, energy storage, offloading/discharging, and loading operations both the offshore-renewable industry have led to advances application of catenary anchor leg moorings (CALM) buoys. Due different seabed profiles, soil stiffness environmental conditions, there is need for numerical assessment investigate behaviour submarine hoses, based on structural ...

The advances observed in the offshore-renewable industry include recent development of a deep draft paired column semisubmersible platform developed for application on dry trees Gulf Mexico (GoM). These developments led to innovation Paired Column Semisubmersible by Jun Zou Houston Offshore Engineering. This paper presents detailed investigation mooring line analysis two different configuration...

The paper aims to design and simulation of a wave energy harvesting system commonly known as point absorber for Ennore port located in the coastal area Chennai, India. geographical condition India, which is surrounded by three sides with seas ocean, has enormous opportunity power production through system. converter device two-body floating its both parts are connected take-off unit acts spring...

The dynamic responses of a new structure combining barge-type floating offshore wind turbine and an aquaculture cage is investigated numerically. First, 5 MW with (FOWT-AC) designed the numerical model established in ANSYS-AQWA. FOWT-AC then checked, natural periods six degrees freedom motion satisfy recommendations DNV specification. Based on reasonable model, comparison study between FOWT und...

Floating offshore wind platform (FOWP) has become the economically favored option for supporting turbines in deep waters. It is urgent to propose new concept designs FOWPs that can be effectively deployed. Additionally, extensive use of steel such platforms significantly escalates costs, necessitating optimization utilization. Motivated by these challenges, a V-shaped floating semi-submersible ...

The floating photovoltaic (FPV) array, which consists of tens or hundreds rows systems, exhibits great economic and environmental benefits. An FPV array arranged in the ocean will be subjected to combined action wind, waves, currents during installation, service, maintenance processes; however, systematic research this field is still lacking. As a representative study on hydrodynamic characteri...

This work presents the Water Energy Point Absorber (WEPA), which is a heaving single-buoy point absorber optimized for specific site off west coast of Sardinia Island. The aim study to present optimization process undertaken identify best configuration in terms performance and cost. carried out thanks simulation tool developed Matlab-Simulink environment verified through commercial software Orc...

How to improve the power generation of wave energy converters (WEC) has become one main research objectives in field. This paper illustrates a framework on use back propagation (BP) neural network predicting capture frustum cone shaped floating body. Mathematical model single body is derived, and radius, semi-vertical angle, mass, submergence depth, take-off (PTO) damping coefficient, stiffness...
