In the world of offshore oil and gas, safety and durability are paramount, but older installations can often hold hidden hazards. Asbestos, once hailed for its heat resistance and fireproofing abilities, was widely used across offshore rigs, production platforms, and support vessels. From insulation in engine rooms to fireproofing in living quarters, asbestos-containing materials (ACMs) provided essential protection in extreme conditions.
However, the very properties that made asbestos invaluable also pose serious health risks. When disturbed, asbestos fibres can become airborne, leading to severe respiratory illnesses and cancers. We walk through the common circumstances where offshore installations might contain asbestos, the typical applications in each area, and why it’s critical to manage these materials safely.
The marine industry is now prioritising the identification, management, and safe removal of asbestos containing materials to mitigate the health risks associated with this once invaluable material.
Why was asbestos used in offshore installations?
Asbestos was used extensively in offshore installations due to a number of advantageous properties it held.
- Heat Resistance: for managing high temperatures in machinery and processing equipment.
- Fireproofing: crucial in preventing the spread of fire in high-risk environments.
- Durability: withstands harsh offshore conditions, including saltwater exposure and mechanical stress.
- Insulation: thermal and acoustic insulation in living quarters and operational areas.
health & safety impact of ACMs in offshore installations
Today, we are now aware of the significant health concerns asbestos can pose, leading to significant change in the marine sector.
- Exposure Risks: inhalation of asbestos fibres can cause serious diseases like asbestosis, lung cancer, and mesothelioma.
- Regulatory Actions: strict regulations now govern the use, handling, and removal of asbestos in offshore environments.
- Management & Removal: Offshore installations often undergo asbestos surveys to identify ACMs, document them in hazardous material inventory lists (IHM), followed by management plans or removal to ensure safety.
Where is asbestos most commonly found offshore?
Asbestos was commonly used in offshore installations, with varying specific applications and reasons for its use. This widespread use highlights the importance of proper asbestos management and the transition to safer materials in the industry.
