The Catcher Field comprises three discoveries all located in Block 2819 of the UK Continental shelf, namely Catcher, Varadero and Burgman in a water depth of approximately 90m which is characterised as being an oil field with relatively low Gas Oil Ratio(GOR). Each Field is to be located as a subsea tie back to a new Floating, Production, Storage and Offloading (FPSO) vessel, exporting oil by shutter tanker and gas by new 10" pipeline connected to the existing fulmar gas line as is illustrated in the figure
There are three potential drill sites, the Catcher drill centre shall be located approximately 3.6km east, the Burgman drill centre shall be located approximately 3.8km south-west and the Varadero drill centre shall be located approximately 4.0km north of the FPSO.
Premier Oil UK Limited awarded Subsea 7 for completion of major piling operations for these drilling templates through 2 phases:
Phase1 (2015) :
To install 3 drilling templates- Catcher 1,
Burgman 1 and the PLEM
Phase 2 (2016):
To Install 4 drilling templates- Catcher 2,
Burgman 2, Varadero 1, Varadero 2 and also
install 3 Gravity Based Structures(GBS)- Catcher GBS, Burgman GBS and Varadero GBS.
The Dawson Contract Piling Ltd supplied piling equipment and personnel to Subsea 7 UK Limited, to carry out piling works on these structures with the following specs.
Working from Skandi Acergy vessel for 2015 campaign and on the Normand Oceanic vessel for the 2016 campaign in approximately 90m water depth the primary hammer, a Dawson HPH15000, successfully drove all forty piles to finished level. This was the biggest project undertaken in the North Sea by Subsea 7 and DCP which lasted 2 years and was judged as a very successful campaign.
