A question of intervention

摘要

The market for light well intervention vessels has both opportunities and pitfalls for new players in equal measure. The best way of defining the well intervention market, specifically the light well intervention (LWI) market, is when well operations and maintenance (except drilling) are carried out on a live well without a riser. Well intervention is used to increase the productivity and lifespan of wells and has been proven to add years to a well's productive life. Typically, these types of operations have been performed from a drilling rig, but in an effort to reduce costs, LWI methods using a monohull vessel have been in development for some time. The benefits of this method include being able to move quickly from one well to another, which reduces production downtime, and also the lower dayrate costs of a monohull vessel compared to a drilling rig (especially for deep water).
