EPmag.com | September 2017 | 19 VALVE TECHBOOK: TECHNOLOGY SHOWCASE tion is available along with internally self-relieving seats, block and bleed capability in both the open or closed position, and explosive resistant O-rings in every valve. cameron.slb.com/wkmd6 Compact Valve Designs Offer Minimal Space and Weight As deepwater projects such as managed-pressure drilling and subsea tiebacks become increasingly common, operators are faced with the difficult task of implementing increased functionality on facil- ities or vessels with limited, expensive real estate. This presents a challenge to minimize the footprint of additional equipment without sacrificing safety, quality or performance. CORTEC is pushing the boundaries of conventional valve manufacturing by utilizing compact ball valve designs to produce turnkey manifold systems that place high levels of functionality in very small spaces. By incorporating advanced technology in raw materials, manufac- turing processes and seal mechanisms, valve per- formance can be offered at the highest level while space and weight are significantly reduced. These designs are manufactured under the framework of API 6A and certified in accordance with API 6AV1, which rates them for boarding shut-down valve service in the Gulf of Mexico. uscortec.com Keeping Operational Costs under Control With more than 10% of an offshore operating bud- get spent on chemicals, platform operators are challenged by flow assurance issues. Operators risk platform shutdowns by under injecting chemicals, leading to costs of up to $1 million per day in lost production. Conversely, over injecting a well by 5% can cost up to $90,000 per chemical, per well. Emerson's TESCOM 56 flow control valve series is specifically designed for offshore chemical injec- tions and allows users to accurately control the flow rate of chemicals over the life of the well regardless of changes in temperature, inlet and well pressure, and well flow. When combined with Emerson's Micro Motion Coriolis meter, the system can auto- matically adjust injections when well conditions change. Users can benefit from a complete injec- tion solution that cuts chemical injection costs and reduces waste and platform downtime. emerson.com Control the Valve at any Distance from Subsea Architecture The Halliburton EcoStar electric tubing-retriev- able safety valve (e-TRSV) solves the challenge to remove hydraulic actuation and its limitations from the subsea architecture. The constraints of hydrostatics and fluid friction between the control center and the wellhead when closing the valve in an emergency situation are eliminated. This enables a fully electric completion system with zero risk of exposing electronics to produced wellbore fluids CORTEC's compact API 6AV1-rated 15,000-psi boarding shut-down valve assembly supplied for Gulf of Mexico project features a 5-in. bore flowline, 1-13/16-in. bypass line and full inconel cladding.
