Evelyn Phase 1 and Gannet E Expansion projects

In Q1 2021 the combined Evelyn Phase 1 development and Gannet E Expansion project was sanctioned by Tailwind.

The Evelyn field will be developed with a single horizontal production well, a new valve skid local to the new well, a subsea production pipeline, a gas lift pipeline and an umbilical tied back to the Triton FPSO. Entry into the Triton production system will be via an existing riser and a newly installed (GEEBB) manifold outside of the FPSO swing-circle.

The Gannet E expansion project will be completed in two stages. First, a second subsea production line and a new manifold will be installed to increase production from the three existing Gannet E wells. Subsequently, a fourth production well is planned for 2022 to add a drainage point in the southern part of the Gannet E field. Access to the FPSO will be via an existing Triton riser.

Tailwind will execute the combined project utilising the project management expertise of existing operating partners in Triton and Gannet E, Petrofac and Dana. The Evelyn development well was drilled in Q3 2021 using the Stena Don Rig, with Petrofac as the well operator. The subsea scope of Evelyn and Gannet E will be delivered as a combined project by Dana (Triton FPSO Operator) with Technip as the Subsea EPIC contractor. The topsides modifications will be managed by Dana and completed during the 2022 Triton annual shutdown.

First oil from Evelyn and the new Gannet E flowline is planned for Q4 2022. The fourth Gannet E well will be drilled in Q4 2022 with tie-in to Triton in Q1 2023.
