London-based Energean has restarted production from the FPSO Energean Power within 48 hours of receiving a restart notice from Israel's Ministry of Energy and Infrastructure, restoring natural gas flows from the Karish field offshore Israel.

Energean took the vessel off production as a precautionary step after the U.S. and Israel began their military operation against Iran. The Strait of Hormuz closed during the action, and multiple regional energy infrastructure sites sustained missile-strike damage. The shutdowns covered both the Leviathan and Karish fields among the Israeli offshore gas developments.

What did the company say about the restart?

"Following notification from the Ministry of Energy and Infrastructure, production was restored to regular levels within 48 hours, delivering natural gas to customers in accordance with contractual requirements," the company said in its statement.

The restart followed disclosure by U.S. President Donald J. Trump of a ceasefire deal with Iran conditioned on the Strait of Hormuz reopening. Energean's restart notice arrived after that conditional arrangement became public.

Which other Israeli fields have cleared to restart?

Chevron, operator of the Leviathan platform with a 29.66% working interest, separately obtained a clearance notification to resume operations at its facility. The Leviathan restart and the Karish restart together account for the bulk of Israeli offshore gas supply that was suspended during the security episode.

Chevron's clearance mirrors the Energean sequence: government notification followed by rapid ramp toward regular production levels. Chevron has not yet published a separate timing detail comparable to Energean's 48-hour figure.

What is the asset and what does it produce?

The FPSO Energean Power is a floating production, storage, and offloading unit stationed at the Karish field in Israel's Exclusive Economic Zone in the Eastern Mediterranean. The vessel handles processing, storage, and offloading of natural gas and condensate from the reservoir.

Energean brought Karish onstream in October 2022. The FPSO had crossed the Suez Canal and arrived offshore Israel in early June 2022, ahead of first production later that year. Production has run intermittently since startup, with the latest shutdown tied to the regional security situation rather than reservoir or facility performance.

What triggered the precautionary shutdowns?

• Catalyst: U.S.-Israeli military operation against Iran
• Strait impact: closure of the Strait of Hormuz
• Asset damage: multiple regional energy infrastructure sites struck by missiles
• Operator response: precautionary shutdown of Leviathan and Karish, among others
• Restart trigger: Israeli Ministry of Energy and Infrastructure notification
• Restart window: 48 hours from notice to regular production at Karish
• Adjacent clearance: Chevron obtained restart approval for the Leviathan platform

What to watch

The benchmark for the coming days is steady-state gas delivery from Karish to contracted offtakers, alongside Leviathan's ramp under Chevron's operatorship. Both fields feed domestic Israeli demand and contracted export offtake via the regional pipeline network. Traders will track any further Israeli ministry directives tied to the ceasefire terms and to traffic through the Strait of Hormuz, which remains the key chokepoint for seaborne crude and LNG flows out of the Gulf. Eastern Mediterranean gas pricing will respond to confirmation of full production restoration at both fields and to any signal on the durability of the ceasefire arrangement.
