Andrew Area Development - Andrew Platform - Kinnoull drill-centre (Update 22-05-2012) BP Exploration Operating Company wish to advise that as part of the Andrew Area Development (AAD) Project, a series of four pipeline bundles and a controls umbilical will be installed from the Andrew Platform to the Kinnoull drill centre. The development comprises the tie-back of three production wells at Kinnoull via a 4-slot manifold towhead and bundle system to the Andrew host platform, terminating in a caisson riser. The bundles will be installed using the controlled depth tow method (CDTM) and will be towed to site from Sinclair Bay, Wick. Once in location each bundle will be sunk into place by flooding the carrier pipe. The tow fleet for each bundle will comprise two Lead Tugs and a Trail Tug, accompanied by the ROV Support/Survey vessel (RSV), a flooding vessel and a Guard Vessel. All four bundles have now been installed. Appurtenance removal for all four bundles will be carried out by DSV in July 2012. The 44” caisson riser was towed to the site by two tow tugs, lowered to a wet store area, then installed on the Andrew jacket by DSV. This scope commenced with clamp installation in mid March and final caisson installation completed early April 2012. The date for installation of the umbilical is currently envisaged to be July 2012 with trenching planned for completion in August 2012. Tie-in spool installation between the four bundles by DSV is envisaged to commence in July 2012. Further activities to be completed in 2012 and 2013 include riser umbilical installation, Andrew and Kinnoull tie-ins and pre-commissioning. Key co-ordinates:

BP Decommissioning – Hutton F ie ld (Update 04-05-2012) BP’s pipeline & structure decommissioning operations have recommenced in the NW Hutton Field (NWH), located in block 211/27a. The pipelines involved comprise 13km of trenched 10” gas line (PL147) that runs from NWH to the Ninian tee and 13 km of untrenched 20” oil line (PL148) that runs from NWH to Cormorant A. The latter includes 3 crossings. The structure is the Subsea Safety Isolation Valve (SSIV) at NW Hutton. In 2011, PL148 (20” oil export line from NW Hutton to Cormorant Alpha) was trenched from KP12.287 at the edge of the Cormorant A 500m zone to KP 6.916 – some 6kms, or approximately 50% of the pipeline. The trench start and end positions are as follows: Start: 61° 06.146′N 01° 04.854′E (KP 12.287 : End 61° 06.311′N 01° 11.606′E (KP6.196) The trench is approximately 0.5m wide and 0.6m deep and has not been backfilled. Some small boulders and pre-existing minor (oil industry and non-oil industry related) have been moved away from the immediate vicinity of the pipeline, and are planned to be removed in 2012. The three crossings located on the pipeline, and the remainder of the pipeline from KP 6.916 at NWH remain in their original condition.

Gryphon Area – Re- instatement Pro jec t (New 23-02-2012) Maersk Oil North Sea is engaged in re-instating facilities in the Gryphon, Tullich and Maclure fields that were damaged last year, when during a storm the Gryphon A Floating Production Storage and Offtake (FPSO) vessel lost anchors and was forced off station.

Re-instatement work will commence on 3rd March 2012 and continue until 19th October 2012. Several construction vessels will be involved in the work including the Skandi Arctic, DSV Wellservicer, FUGRO Symphony, and the Skandi Achiever. The Gryphon A FPSO is expected back on station during mid-July.

Guard vessels will be used during all periods when the work is incomplete and a construction vessel is not on site.

Location Coordinates Gryphon 59°21.653' N 01°34.159' E South Gryphon (subsea field) 59°20.338' N 01°32.487' E North Gryphon (subsea field) 59°22.104' N 01°32.556' E Maclure (subsea field) 59°22.069' N 01°36.264' E Gryphon Sub Sea Cluster 59°21.006' N 01°33.012' E

Skippers of fishing boats and other vessels are requested to keep clear of these locations until completion of the work. For further information, please contact: Shona Campbell, Subsea Project Manager, Maersk Oil, Tel: +44(0)1224 242175, email: [email protected]

I thaca Energy – Athena F ie ld Development (Update 13-02-2012) Mooring, STP buoy, structure, MWA and flexible flowline installation works have now been completed. The associated seabed construction work is now progressing within the next period, trenching infield continuing with diving tie-in works. The Athena Field will be developed by means of a subsea tie-back to the BW Athena FPSO (Floating Production Storage Offloading) which will lie about 2 km South West from the Athena Drill Centre location. The initial development (works described further on) consists of 4 production wells and 1 water injection well. The FPSO will be turret-moored and freely weather-veining. Oil export is via shuttle tanker. The BW Athena FPSO will provide the host production operating services for Athena including provision of oil and gas processing, produced water treatment and disposal, electrical power, subsea control and chemical injection, water injection.. Mooring and STP Buoy System Description The STP Buoy is a mooring line tethered buoy utilised to locate the BW Athena FPSO at the Athena site. At the centre of the STP buoy is a turret, the outer section of the buoy is free to rotate around the turret. The outer part of the buoy, when pulled into the FPSO, allows the FPSO to rotate or weathervane around the geostationary turret.

The STP Buoy mooring system comprises of 9 off mooring lines consisting of a Spiral Strand Wire Rope section and a Studless chain section connected to Suction Anchor Piles. The Suction Anchor Piles and chain section will be installed first and the STP Buoy c/w Spiral Strand Wire Ropes will then be towed to the Field and connected to the pre-installed mooring chains. STP Mooring Arrangement:

STP Mooring Buoy circa 7.4m Dia x 14.1m tall 9 off Mooring Lines comprising of 200m Spiral Strand Wire Rope & 715m R4 Studless Chain 9 off Mooring Anchor (Suction Piles), 6 off Dia 5m x 13m, 2 off Dia 6.5m x 10.5m & 1 off Dia 5m x 10.5m

Subsea Facilities Description The subsea flowline system will comprise an 8” insulated production flexible flowline, 3” service flexible flowline and 8” water injection flexible flowline. The flowline systems will run between the Riser Base structure and subsea manifold at the Athena Drill Centre. Flowlines and umbilicals will be trenched to approx. 1m below the seabed with the untrenched ends protected by concrete mattresses. Rigid spools and controls jumpers will be connected between the subsea manifold and the wellheads. These will be protected by concrete mattresses. All dynamic products will be secured over a Mid Water Arch System. During the construction phase, if construction vessels are not on site, the infrastructure will be protected by a guard vessel.

Banff Oil Field – 3nm Exclusion Zone (Disconnection of FPSO/FSU) (New 25-04-2012) Please be advised that the Banff FPSO and Apollo Spirit FSU are off location until summer 2013. There is a 3nm exclusion zone in force with a guard vessel “Victoria May” patrolling the area. The centre of this exclusion zone is at 57°00.00’N 001°17.50’E. This exclusion zone is in place due to the significant oil & gas structures below the surface, which may pose a risk to fishing activities. The exclusion zone will remain in place for some time yet whilst activities are undertaken to secure the area both underwater and on the seabed. For further information, please contact: Bob Walker, Teekay Petrojarl, Tel: +44 1224 793415, Email: [email protected]

Snagging Hazard – Obstruc t ion (New 17-01-2012) Please note that there is an vibro-corer obstruction which is 3.5 m high and 1m width increasing to 4m wide at it's base, which is expected to be flush to the seabed, there is approximately 100m of 16mm wire rope attached to the corer. Weight in air is 1.25t, although it is our expectation that the core barrel will be extended 3m into the seabed, and that the object is thus firmly anchored to the seabed.
