Cameron Willis Subsea Chokes xxx The Willis Tradition In 1975, Cameron Willis manufactured the world’s first subsea choke for the Mobil West Delta Project in the Gulf of Mexico. Such early subsea chokes were based upon the design of manual surface chokes and used multi-orifice trim technology. These MOVs (Multi Orifice Valve) controlled flow via two discs with circular orifices. As one disc was rotated with respect to the other, the flow area was adjusted. By mid-2003, Cameron Willis Subsea Chokes will have been used in more than 1000 installations worldwide, utilizing state-of-the-art technology including: • Selection of Trim Styles • High Pressure, High Temperature • Retrievable Insert or Fixed Non- Retrievable Designs • Advanced Actuation and Adjustment Features • Fast Acting Capabilities. Cameron Willis Subsea Chokes are designed for use in production, water injection, gas injection and gas lift applications. Cameron Willis chokes typically provide the following functions in subsea applications: •Balance pressures from different wells to a common manifold • Reduce flowline pressures and costs •Protect against reservoir collapse during start-up •Control flow rates to extend production life •Protect subsea gate valves from high pressure drops during opening and closing (start-up and shut-down) • Fast operating benefits. Two types of Cameron Willis Subsea Chokes are available – non-retrievable insert (fixed) and retrievable insert. Non-retrievable insert chokes are designed to be permanently attached to subsea structures. Cameron Retrievable Willis insert Nonchokes are Retrievable Insert designed so Choke that the trim, actuator and retention mechanism can be retrieved to the surface. Cameron Willis Subsea Chokes can be supplied with plug and cage or external sleeve trims. Trims are available for bi-directional flow, gas injection, gas lift, water injection (typically multi-stage) or water alternating gas (WAG). This wide selection of trim gives Cameron Willis customers the ability to interchange trims to accommodate changes in field parameters.

Non-Retrievable Insert and Retrievable Insert Designs WThe “90-Day” Choke hether the application is shallow or deep water, subsea Christmas trees or manifolds, there is a Cameron Willis subsea choke available. In shallow water applications, the popular non-retrievable insert (fixed body) choke design is an ideal choice. In applications where the use of divers is impractical, the retrievable insert design offers many advantages. Fixed Non-Retrievable Insert Chokes The first Cameron Willis Non-Retrievable Insert (fixed body) Subsea Choke was installed in 1975 and today, these rugged chokes have proven to be the reliable choice for shallow water service. In the non-retrievable insert design, the choke body is permanently mounted to a subsea structure such as a Christmas tree or manifold. The choke body may also be incorporated into a retrievable skid for use with flowmeters, instrumentation, etc. To maintain or replace the choke and/or trim, a diver can be used to disconnect the choke from the structure, or the structure itself can be retrieved. The choke can be adjusted by an actuator, ROV or diver. Non-retrievable insert chokes are available in pressure ratings up to 15,000 psi, temperature ranges from -50°F to 350°F (-46°C to 177°C) and trim sizes from 2” through 6”. Cameron Willis Non-Retrievable Insert Chokes are designed for 20 years of service life and meet or exceed all API 6A and 17D requirements, as well as NACE MR-01-75 requirements. Retrievable Insert Chokes Cameron Willis supplied the first retrievable insert choke in 1991. Since then, these highly successful chokes have been installed on subsea systems in varying water depths around the world. The retrievable insert choke design allows the choke body to remain permanently fixed to the subsea structure while the trim, actuator and retention mechanism are retrieved as a self-contained package to the surface. Two types of insert retention designs – clamp-style and crown-style – are available to attach the retrievable components to the choke body. Insert retrievable chokes are available in pressure ratings up to 15,000 psi, temperature ranges from -50°F to 350°F (-46°C to 177°C) and trim sizes from 2” through 6”. All Cameron Willis Retrievable Insert Chokes are designed for 20 years of service life and meet or exceed all API 6A and 17D requirements, as well as NACE MR- 01-75 requirements. Cameron Willis Retrievable Insert Choke with Clamp Connector Manufacturing Capabilities The Cameron Willis Longford, Ireland facility has global responsibility for the design and manufacturing of all subsea chokes. In addition, the plant also manufactures subsea gate valve actuators for Cameron Offshore Systems. The plant is equipped with CNC lathes and machining centers. The facility also contains weld cladding stations, five hydrotest bays, TVmonitored hydrostatic and gas test facilities rated to 30,000 psi and in-house radiographic inspection. Cameron Willis is a business unit of the Cameron division of Cooper Cameron Corporation and utilizes the full complement of Cameron resources including sales and service centers in 21 countries and CAMSERV Aftermarket Service Centers in 11 countries. With so much global coverage, there is always a highly qualified Cameron Willis representative to help you with your subsea chokes, surface chokes, actuators and other drilling and production product needs.
