Pipe-in-pipe technology adapts to changing needs in deep and shallow water

Over the past two decades, the pipe-in-pipe (PiP) product has become an essential part of the subsea field development engineer's "tool box." Due to its high insulation performance, it minimizes heat losses from the transported fluid to the environment that more traditional subsea coatings cannot provide. In 2014, Technip installed its 50th PiP via the reel-lay method; the first project was in Australia in 1989. Along the way, the company has advanced the technology at various points.

Smart valve system provides interventionless completions

The artificial lift method of gas lift is an increasingly popular means of boosting production from wells with lagging reservoir pressure. The method injects a compressed gas into well annulus between the production tubing and casing. The industry need for lower risk, interventionless alternatives to gas lift valve changeouts prompted Baker Hughes to develop a smart gas lift valve that could function as a dummy valve during completion operations and then convert to a live valve, without the need for a well intervention. This is achieved through the use of a disintegrable barrier or plug made of nanostructured composite material.

Industry addressing challenges of deepwater, data management
