Controlling differential pressure is the key to reducing wall thickness and costs for deepwater gas export systems. With new fields regularly being developed in ultra-deep waters and increasingly remote locations, long-distance export solutions for natural gas that cannot be flared are becoming project-critical. A new concept has been unveiled that could dramatically cut pipeline construction and installation costs while also representing a viable economic alternative to existing transportation options such as floating LNG units. According to DNV, its deepwater gas pipeline concept could enable huge savings on the costs of constructing and installing such lines by reducing the amount and thickness of steel used without compromising pipeline safety and integrity.
