| Summary: | Malaysia is underlain by soft soils. This soft soil has the possibility to amplify the
seismic waves from distant earthquakes in subduction zones such as: Sulawesi and
Sumatra that approach the bedrock of Malaysia. However, the fixed offshore structures
in Malaysian waters are not designed to undertake the seismic loadings. Therefore, a
study of offshore platform integrity under seismic loadings in Peninsular Malaysia
Operation (PMO), Sabah Operation (SBO) and Sarawak Operation (SKO) is necessary
to perform to minimise casualties and fatalities of Malaysian offshore platforms
although Malaysia is at least 600 km away from the active earthquake zone. Thus,
three representative platforms, which are Duyong in PMO, Tukau in SKO and
Kinabalu in SBO are selected for this research. Malaysian offshore structures design
based on PETRONAS Technical Standard (PTS) have been lacking of seismic waves
consideration in the structural design. However, recent earthquake tragedies happened
far away from Malaysian waters have been felt by Malaysian offshore structures.
These incidents created a conflict on the assumption stated by PTS where Malaysia is
located at seismically stable zone. |
