ECONOMIC REPORT 2013

• Construction works to be completed over a
three-year period from 2013 to 2015. A flotel
(floating hotel) will be on location for ten
monthstoprovideadditional accommodation
over the various phases of construction.
At their peak, the upgraded facilities are
expected to produce 55,000 boepd from the
MAR fields and the annual average will be
some 35,000 boepd
The BLP has four significant elements (jacket,
deck, bridge and flare), requiring the design,
procurement, construction and commissioning of
over 17,000 tonnes of materials and equipment.
The jacket includes three caisson riser systems
to facilitate the tie-in of the Cayley and Shaw
pipelines and umbilical lines, whilst providing
spare risers and a J-tube for future developments.
The deck houses state-of-the-art process
facilities for separating the hydrocarbon streams
from Cayley (gas condensate) and Shaw (oil and
associated gas), produced water treatment and
water injection. The development uses existing
oil and gas export subsea facilities, although gas
will now be exported through a new rigid caisson
riser system located on the BLP.
Subsea isolation valves (SSIVs) are being installed
on all new production and gas lift pipelines and
will be contained within a single structure to the
north-west of the BLP.
The subsea field developments of Cayley and
Shaw require 100 kilometres of pipelines to be
procured, assembled and installed to tie-back
seven subsea wells from three drilling centres.
Some 600 kilometres of control hoses and
tubing will be manufactured into umbilical lines
contained within pipeline bundles to distribute
hydraulic fluids and chemicals across the fields.
Key Facts
•
TSE UK and its co-venturer, Marubeni, will invest
£1.6 billion in the MAR project
•
MAR encompasses four fields in Palaeocene-aged
reservoirs (Montrose, Arbroath, Arkwright and
Brechin), four fields in Jurassic-aged reservoirs (Wood,
Godwin, Cayley and Shaw) and a Zechstein-aged
reservoir (Carnoustie)
•
The fields are located approximately 210 kilometres
north-east of Aberdeen
•
Since production started in 1976, over 270 million boe of
oil and associated gas have been produced
•
The MAR project will unlock 100 million barrels of
reserves when it comes on-stream in 2016 and will create
or sustain more than 2,000 jobs during construction,
fabrication, installation, subsea engineering and drilling
•
Oil is exported via the Forties Production System (FPS) to
Cruden Bay and then on to Grangemouth
•
Gas is exported via the Central Area Transmission System
(CATS) to Teesside
•
The project was the first to be awarded a BFA
