Offshore Decommissioning

What Does Decommissioning Entail?

As offshore facilities and vessels reach the end of their operational life, responsible decommissioning becomes a critical phase in the asset lifecycle. ABS supports owners and operators in navigating this transition with a focus on safety, sustainability and regulatory alignment.

The global energy transition has intensified the need for environmentally conscious operations. Offshore decommissioning presents complex challenges, from aging infrastructure to the removal of assets with compromised structural integrity. These activities carry risks to both personnel and the environment, including potential injury and the release of hazardous materials. Whether at the project site or recycling yards, maintaining asset integrity is essential to protect people and ecosystems.
