Government Authorities & International Agencies

Setting appropriate compliance standards is a first step in establishing the conditions for successful decommissioning – balancing minimising risk of environmental impact against the cost and technical and Health & Safety risks of operations. RESL has extensive experience in assisting regulators in setting suitable standards and guidelines with the aim of providing a flexible approach which allows specific project challenges to be managed without additional unnecessary costs. This often has benefit for both the operator and the local legislator and economy.
