Karish Update - FPSO Arrival In Israel

London, 6 June 2022 - Energean plc (LSE: ENOG, TASE: אנאג) is pleased to announce that the Energean Power FPSO has arrived on location in Israel.

The FPSO was transported by two tugs from Sembcorp Marine's Admiralty Yard in Singapore to Israel. The 5,532 nautical mile-long journey took 35 days, crossing six seas and passing through the Suez Canal.

Energean will immediately commence hook-up and commissioning operations, which includes risers and jumpers installation as well as the commissioning of the sales gas pipeline. Energean expects approximately three - four months of commissioning before first gas, which remains on track for Q3 this year.

Mathios Rigas, Chief Executive Officer of Energean, commented:

"I am delighted to confirm that the Energean Power FPSO has arrived on location in Israel. This marks a major step forward in delivering first gas from Karish which remains on track for Q3 2022. We look forward to continuing our progress through Karish first gas, the commercialisation of the newly defined Olympus Area and contributing to energy security and competition of supply for the region."
