簡介：卡梅隆DC采油樹全電化控制系統，為四井應用，其中一個樹可以調節為失效備用樹。節流管匯安裝于水深131英尺處，由11.2英里遠的平臺來控制。系統的頂部關鍵部件包括一個主控站，監控海洋系統，四個電源與通信單元，每個采油樹兩個。
Cameron’s DC Tree made a splash at the recent Offshore Technology Conference after enjoying its first installation for Total E&P Nederland B.V. in the Dutch Sector of the North Sea in September 2008. The system includes a three-well template/manifold with a two-well initial installation and the option for a third. The all-electric control system is configured for a four-well application, designed to accommodate the fourth tree as a step-out. The template/manifold is installed in 131 ft (40 m) of water and is controlled by an existing platform 11.2 miles (18 km) away. Production is piped 6.2 miles (10 km) to an unmanned platform.
Key topsides components for the system include a master control station, which controls and monitors the subsea system, and four electrical power and communication units, two for each tree.
Without the burden, limitations, and expense of hydraulics, the system delivers key advantages over conventional systems, including savings in cheaper umbilicals, host facility space and weight savings, and the elimination of hydraulic fluid costs. Additionally, step-out distance is virtually unlimited, and the system can operate in as much as 15,000 ft (4,572 m) of water.
Because it is all-electric, it provides full compliance with zero tolerance of fluid emissions, and the size of the umbilical is greatly reduced.
Cameron is using the DC Tree in conjunction with other subsea technology, primarily its high-integrity pressure protection system (HIPPS) and its multiple application re-injection system (MARS), to act as “enablers” to its subsea processing portfolio. HIPPS protects flowlines against overpressure. Equipped with intelligent safety and control systems, the system meets stringent safety levels and ensures constantly high production levels. Additionaly, HIPPS offers the flexibility to extend field layouts and to branch off new lines from existing systems, even when the pressure ratings are different.
MARS enables any process to be fitted to any well at any time. This is achieved by establishing a retrofit coaxial access port which has been compared to a USB port for a wellhead. Unplanned maintenance no longer requires major field shutdowns or infrastructure decommissioning This technology delivers a low-cost and flexible field development strategy for new and existing fields.
