Abstract

The global demand for energy and power, particularly fossil fuel is constantly shooting
up despite the economy breakdown happening worldwide. Oil and gas specialists have
since been improving their engineering techniques on the designs of offshore
platforms for instance, to create economical and sustainable ways to conduct their
exploration and production activities. This is due to the fact that these structures are
often subjected to high flow velocities, induced by waves and currents. When
hydrocarbon from the seabed is extracted for an extended period of time, there might
be reduction in pressure, which causes the seabed to cave in. In other words, seabed
subsidence can happen due the reservoir compaction. A platform experiencing
subsidence promotes reduction of air gaps, which eventually allows the waves to
attack the lowest decks. Wave-in-deck phenomenon for fixed jacket platforms at
shallow water condition has been reported as a notable risk to the workability and
reliability of these structures.
