Marine submersible buoy systems are widely-used equipment for ocean resource development. The marine system studied in this paper consists of the buoy, battery compartment, anchor block, mooring line, and power supply cable. To study mechanical behavior obtain speed variation each component during last deployment, establishes free surface computational fluid dynamics model based on VOF method. ...

Due to the lack of sheltered area, Norwegian fish farms are expanding more exposed and remote sites. The severe environmental conditions in sites can increase risk structural failure during aquaculture operations. In present study, program FhSim is employed conduct time-domain simulations investigate responses a single-cage 1 × 4 multi-cage farm due breakages mooring lines. influences on tensio...

The Offshore Aquaculture Consortium (OAC) was created as a collaborative, Gulf-wide, interdisciplinary research and development program in response to the U.S. Department of Commerce Aquaculture Policy. OAC research has demonstrated numerous components of offshore aquaculture in the Gulf of Mexico including permitting requirements, mooring systems, cage/mooring survival during several hurricane...

In practice, the ocean waves are short-crested and three-dimensional. The primary objective of present research is to form a better understanding dynamics offshore floating wind turbines in multi-directional waves. modelled using spreading exponent function. wave directionality effect on dynamic performance semisubmersible turbine studied. waves, longitudinal response reduced whereas lateral am...

A bio-optical mooring, which was deployed for 240 days during 1987 in the western Sargasso Sea (-35øN, 70øW), provided among other things a detailed record of the seasonal distribution of chlorophyll a fluorescence and the scalar irradiance of photosynthetically available radiation. This data base was augmented by shipboard measurements of chlorophyll a concentration, chlorophyll a fluorescence...
