Abstract:
The expansion of near-shore aquaculture is becoming more difficult because of multi-use
issues and environmental impact concerns, the feasibility of moving aquaculture into the
open ocean is being studied. However, natural disasters such as hurricanes and storms can
cause severe damage to the integrity of structural floating system. To avoid mooring
system failure, selecting an appropriate breaking strength for mooring lines is becoming
an important issue in marine aquaculture industry. The study evaluates the secure of a
mooring system based on environmental loadings. To enable the optimum design and
performance a mooring system in the energetic open ocean, numerical modeling
techniques and model testing are being utilized. The numerical model employs the
analysis approach in which wave and current loadings on anchor, buoy and lines elements
that drive the system dynamics. The validity of numerical evaluation was then compared
with model experiments carried out in the Towing Tank at Marine Technology
Laboratory, UTM. Understanding these differences will help to establish appropriate
safety factors when designing large marine offshore farms using the model.
