Total North Alwyn Platform
1: BOP Panel System Upgrade
System Design, Manufacture, Assembly, ATEX Certification, In-house Testing & FAT.
Monitor Systems were approached by KCA Deutag RDS to design and manufacture a BOP control panel upgrade for the Total North Alwyn Platform.
The BOP control panel upgrade incorporated a Drillers control panel, Lifeboat control panel, Toolpushers control panel and a Barrier enclosure.
Lifeboat’s BOP Control Panel. Made from 316 stainless steel, (1000 x 800 x 300mm) the enclosure was rated to IP66, (ensuring protection against water and dust). The control panel was designed and manufactured suitable for use in a Zone 1 area.
The BOP control panel features a number of illuminated pushbuttons, indicator lamps, meters and switches for functions such as choke, kill, upper/lower rams, shear rams, annular, annular & manifold pressure regulators as well as monitoring various alarm conditions, pressure and flow rates.
Driller’s BOP Control Panel. Made from 316 stainless steel, (1000 x 700 x 300mm) the enclosure was rated to IP55, (ensuring complete protection against water ingress). With the same facia design and controls as the Lifeboat BOP control panel, the Driller’s BOP control panel features the same configuration of illuminated pushbuttons, indicator lamps, meters and switches for safe operation and control.
Toolpusher’s BOP Control Panel. Made from 316 stainless steel, (500 x 500 x 220mm) the enclosure was designed for Safe Area use only. With a similar graphical facia, the smaller BOP control panel also features a range of pushbuttons, indicator lamps and meters for safe and efficient operation.
HPU Barrier Enclosure. Made from 316 stainless steel, (300 x 300 x 220mm) the enclosure was designed suitable for installation in Zone 2. The HBU Barrier enclosure contains the I.S (Intrinsically Safe) barriers to provide power & signal to the I.S Flowmeter.
Hazardous Area Classification. The Driller and Lifeboat BOP control panels were designedfor use in Zone 1 (explosive mixture) gas environments.
The Toolpusher’s BOP control panel and HPU barrier enclosure were designed specifically for safe area use.
Facias / Graphical Overlays. All graphical overlays were reverse printed on polycarbonate. An additional graphic overlay was supplied for the Drillers, Lifeboat and Toolpushers control panel, giving the option to swap between 13 5/8” and 20 3/4” riser configurations. The additional overlays are easy to position and are secured automatically.
2: Platform Control Room Remote Console
Monitor Systems Engineering was approached by Petrofac to discuss the feasibility in designing a communications console to remotely control the Dunbar Platform from the central control room of the North Alwyn Bravo Platform.
The new console houses all communications and interface equipment to enable a safe and effective operator station. It facilitates the data communications between the two North Sea platforms by utilising an existing subsea fibre optic infrastructure. The new remote console includes CCTV, UHF, VHF and telephone hot-lines for full communications, accessibility and control.
When installed and commissioned in the central control room of the North Alwyn Bravo platform, the new control console will provide operators with full remote access to the Dunbar telecommunications systems.
ABOUT: The Alwyn facilities were initially designed for a service of 20 years and to extend an efficient and safe operation beyond 2020, the company Total launched in 2004 an enhanced inspection and maintenance programme. In addition, major works have been completed to reduce the emission profile of the hub.
Thirty years ago, first oil was produced from the North Alwyn platform in the UK North Sea. The Alwyn field, located 440 kilometers North-East of Aberdeen was brought on-stream in November 1987. North Alwyn is currently one of the largest oil and gas processing platforms in the UK North Sea acting as a gathering hub for nearby fields.
