Operational Update:

Completion of Turret Mooring System Installation

Hurricane Energy plc, the UK based oil and gas company focused on hydrocarbon resources in naturally fractured basement reservoirs, is pleased to provide an operational update in relation to the EPS development of the Lancaster Field.

The turret mooring system, including the newly-constructed buoy for the Aoka Mizu FPSO, has been successfully installed at the Lancaster field, subject to final classification society approval. The operation utilised the Normand Installer offshore construction vessel, together with associated support vessels.

The completion of this operation is a critical milestone required to allow the installation of the subsea umbilical, risers, and flowlines ("SURF"). SURF is the last phase of the offshore installation programme in preparation for the arrival of the Aoka Mizu FPSO at the Lancaster field. The buoy will now sit submerged below the surface, held in place by 12 mooring lines connected to piles, until the FPSO's arrival.

Dr Robert Trice, Chief Executive, commented:

"We are delighted to have completed this weather sensitive turret mooring system installation. The SURF installation campaign is due to commence shortly, with the mobilisation of subsea equipment expected to begin in the coming weeks. We look forward to providing further updates in the run-up to first oil, which remains on track for 1H 2019."
