Water Jet Cutting an Option throughout Structure's Life.

Technology advancements in recent years have enabled amazing things in offshore oil and gas developments. High-strength steels have been developed that make structures lighter and more efficient. In order to maximize the performance of the steel, techniques have been developed that make it possible to sever steel plates with no heat affected zone (HAZ). Heat affected zones occur with all hot work cutting methods (oxyfuel torch, plasma, etc.) and change the characteristics of the material around the area where the cutting or welding occurs. Those changes can affect material hardness and weldability, and can cause discoloration or distortion.

Abrasive water jet cutting technology cuts through steel without creating a heat affected zone. This enabling technology has been used on end-of-life operations for years, and recently was employed on two topsides operations for a major operator.
