Causes and consequences of odours from marine growth organisms.

Abstract

From the Executive Summary: “After years of immersion, the subsurface section of offshore oil and ga platforms will have variable amount of marine growth of uneven thickness attached to them…During decommissioning, metal jackets are cleaned of marine growth, cut into pieces and recycled. During this process, the marine growth can emit substantial odours to lead to public concern…The report identifies the circumstances where odours emitted during the cleaning process are likely to be more intense…Mitigating the problem during decommissiong will call for rapid removal of marine growth and spraying odour suppressants when odour levels are high. However, the best approach will be the use of preventive measures such as clamp-on devices on jackets prior to removal for the physical cleaning of the top ca. 20 m of marine growth prior to decommissioning to land…”
