Catcher Hook Up & Commissioning

23rd October 2017

Executive Summary

• Vessel arrived in Nigg on 8th October and was deployed in the field on 18th

October

• Removal of cone plate and hook-up with the buoy have been completed
• Hook-up of risers ongoing; hook-up of umbilicals plus reinstatement of

equipment and leak testing of pipework will follow

• Commissioning activities are running in parallel
• Introduction of hydrocarbons after flushing of gas export line and final

rotation testing

• Forecast for first oil remains on track for before year end
• Field ramp up will be over 3-4 month period with Catcher being the first field
• n line followed by Varadero and Burgman
• Full field plateau production of 60kbopd will be achieved at this time
• Expected to trade in line with Brent

• Geostationary pipework will be reinstated along with

power, instrumentation and shipside structures

• Production lines will be connected to the swivel
• Hook-up equipment such as buoy bumper bars, hang-
• ffs and sheave arrangements will be removed

• Swivel stack (270t) in sail away location to allow buoy

installation

• Will be skidded to the centre of the turret, aligned

with the buoy, mated and bolts tensioned

Catcher Commissioning

October 2017 | P5

• Where possible equipment was leak tested, commissioned and

systems accepted by operations in Singapore prior to sail away

• The voyage and movement of the vessel and equipment

requires them to be re-tested ahead of the introduction of hydrocarbons

• Vessel activities:

– Pipework: Nitrogen/helium testing; and Deluge testing – Tubing: Leak testing – Electrical & Instrumentation: Pig tail termination & tests; and Removed equipment reinstated and tested

• Subsea activities

– Completion of umbilical core flushing – Gas export riser dewatering – Tree & manifold valve function testing

• Final activities

– Testing of offloading hose connection – Final rotation test

• Ready for the introduction of hydrocarbons from Catcher field

Gas export line – commissioned prior to start up Teekay shuttle tanker

Catcher Commissioning & Production Profile

October 2017 | P6

• Catcher is the initial field on production due to it’s ability to produce oil in a stable fashion for the first stages
• f the FPSO plant commissioning
• Each field will be brought on in the following manner

– Well clean up (initial clean up restricted by rig surface equipment) – Well test through the subsea multi-phase meters – Restricted rate to manage gas rates through commissioning period

• Following gas train commissioning completion and the introduction of Burgman fluids the plant will be run at

60 kbopd
