Abstract

As exploration for new oil and gas sources goes deeper into the ocean and farther from shore, valves in service to that industry will have new pressure, temperature and durability requirements. Deep and ultra-deep prospects will continue to eclipse mature shallow water hydrocarbon production, which has seen a decline in capital expenditures in recent years. Thanks to major technological improvements and deep water exploration and production successes, the definition of deep water have changed over the last decade passing from a threshold of 200 meters to over 1,000 meters.

What was considered deep 20 years ago is now considered shallow and the greatest potential is now represented by fields located at depths of over 1,000 meters? In fact, most new projects under development today range between 1,000 and 3,000 meters. These deeper water projects together with increased distances from shores and increasingly harsh environments represent the next frontier in exploration, production, and transmission. As far as valves, many new challenges in the high-pressure, high-temperature subsea environment exist, including the need to develop special alloys, coatings, elastomers, and thermoplastics that can withstand the rigors of ultra-deep operation.

This paper presents the modeling, simulation, pressure testing, and Hyperbaric testing of a subsea ball valve manufactured in Hawa Valves India Pvt. Ltd. A Hyperbaric chamber built to simulate pressure condition at a 3000m depth of water. Description of the test specimen is 2- inch ball valve test medium is water and nitrogen and the rated pressure is considered as per the ASME B16.34 and test medium of the hyperbaric test chamber is water. Design water depth pressure is considered as 330bar. Obtained results not only provided people with the access of understanding the hyperbaric pressure testing of sub-sea valves and also provide a brief understanding of the testing procedure.
