Part I of this new practical book therefore analyses each professional area relating to decommissioning. As well as these professional disciplines and agreements, Part I contains chapters on UN law, OSPAR regulations, government policy, offshore contracting, health and safety and technical issues. These topics are further examined using a case study from a completed North Sea decommissioning project. Part II provides an international comparative analysis. It features coverage of how international laws on decommissioning are implemented in the major oil-producing jurisdictions around the world.
