Abstract:
Complex system design is increasingly adopting risk and reliability analysis for safety,
efficiency and sustainable development purpose. Approach population and urban
development expand in landscape island countries or countries with long coastlines, city
planners and engineers resort to land reclamation to ease the pressure on existing heavilyused
land and underground spaces use risk based design for reliable purpose. Risk based
design has also been used on system that use fill materials from seabed, system hills, deep
underground excavations·, and even construction debris, engineers are able to create
relatively vast and valuable land from the sea. Through risk based design of aquaculture
industry is one of the fastest producing sectors in the world. Seaweed farming has become
an economically important natural resource for Malaysia since 1978, when it was first
introduced to Sempoma, east coast of Sabah on a commercial scale. It has develop the
aquaculture activities in Sabah as a second largest contributor from marine aquaculture
which produce 60% from total value of exported fisheries product at RM114 million
(1994-1997). Considerable interest exists in developing open ocean aquaculture in
response to a shortage of suitable, sheltered inshore locations and possible husbandry
advantages of oceanic sites. Adopting the concept of very large floating structure in
aquaculture farming in offshore environment is like to produce more aquaculture product
like seaweed. All being property and support for growing aquaculture industry. Risk
analysis study of offshore aquaculture ocean plantation system is very important to
determine the system functionality and capability that meet sustainable and reliability
requirement. The research qualitatively assesses system risk and quantifies mooring
failure probability, maximum force and required number of mooring as well as associated
cost.
