  • Generator
  • Firewater pump system
  • Seawater uplift
  • Macerator and reverse osmosis unit

Mezz Deck 1

  • Collaboration Room
  • Permit Office, OIM/Team Leader Office
  • Open Plan Office Area
  • Laundry, mess and Locker Rooms
  • External area containing air compressors and vendor skids

  • Medical Centre
  • OIM team leader & medic living quarters
  • Kitchen/cold Storage area and dining area
  • Auditorium and Gymnasium
  • Helicopter Departure Lounge

Mezz Deck 3

Weather Deck

LER (Equipment Room) and HVAC Plant Room

The Cygnus QU Module has a Helideck sized for a Sikorsky S61 or EC225 helicopter that is linked by bridge to the PU platform.

Additionally, the module includes:

  • One ram Luffer crane
  • 800kw diesel emergency generator
  • Seawater lift and filtration system
  • 230kw instrument and plant air system
  • 530m3 diesel driven firewater pumps
  • Inert gas generator
  • Two 90 person TEMPSC life boats (Totally Enclosed Motor Propelled Survival Craft)


BGEN worked under challenging conditions, due to a reduction in timescale and a growth in work scope. However BGEN successfully overcame these challenges to substantially complete the build prior to the sail away of the module. The final project is worth in excess of £10 million,
completed within 240,000 project hours and with a peak labour force of 235 men.

The quality of the work and the high level of construction completion is a testament to the skill and hard work of all those involved and to the excellent teamwork between all the parties at site.
