Development of Preliminary Mercury Management Guideline in Platform Decommissioning for Peninsular Malaysia Operations

Mercury, being highly volatile, can easily adsorb and desorb from steel parts of the
offshore platform causing safety and health risks from its vapour exposure. With its
tendency to accumulate over time, it is a threat as the platform reaches the end of its
design life. In Malaysia, the issue present is the lack of data available to properly
assess the mercury exposure conditions offshore especially during the
decommissioning process. This research was carried out to identify the mercury
contaminated platforms in Peninsular Malaysia Operations (PMO) and to assess the
risk levels of mercury on the platforms. It is also to establish a baseline for mercury
exposure in offshore platform decommissioning by analysing the decommissioning
scenario in Malaysia, the sources of contamination and the health and safety status of
workforces involved.
