Egypt Refloats Drone-Damaged LNG FSRU Energos Winter After 14-Hour Salvage Operation
Our take

The recent incident involving the Energos Winter, a floating storage and regasification unit (FSRU) damaged by a drone attack off the coast of Egypt, underscores a concerning escalation of risk within the global energy infrastructure. The successful refloating of the vessel after a 14-hour salvage operation is a testament to maritime engineering capabilities, but the attack itself highlights vulnerabilities previously considered remote. This event, coupled with recent disruptions like the halting of grain terminal operations at Russia’s Novorossiysk port after a Ukrainian strike [Grain Terminals At Russia’s Novorossiysk Port Stop Operations After Ukrainian Strike Causes Damage & Kills 3] and the ongoing challenges faced by even the largest cargo ships navigating depth restrictions [Depth Restrictions Limit Cargo Capacity Of Largest Cargo Ship To Call Port Everglades], points toward a new era of operational complexity and potential instability in key maritime corridors. The proximity of the attack to a nearby LNG carrier, the GasLog Salem, further emphasizes the cascading risk inherent in these incidents.
The use of drones in this context represents a significant shift. While maritime security has long considered traditional threats like piracy and sabotage, the accessibility and relative ease of deploying drone technology introduces a novel and rapidly evolving challenge. The Energos Winter incident isn't an isolated case; it follows a pattern of increasingly sophisticated attacks on critical infrastructure, including the aforementioned incident in Novorossiysk. This also echoes advancements in autonomous maritime technology, as exemplified by the U.S. company's 3D-printed drone boat [U.S Company 3D Prints Drone Boat Using Robot Arms To Deposit Materials Layer By Layer], demonstrating the potential for both beneficial and malicious applications of unmanned systems at sea. The fact that this occurred in a region vital for LNG transit adds another layer of urgency. The Suez Canal, a critical artery for global trade, relies heavily on LNG transport, and any disruption to this flow has far-reaching economic consequences.
The implications for the LNG sector and broader maritime industry are substantial. Security protocols will undoubtedly be scrutinized and likely strengthened, potentially leading to increased operational costs and delays. The existing reliance on vulnerability assessments, often focused on traditional threats, will need to be significantly expanded to incorporate the dynamic risk posed by drone technology. Furthermore, the incident necessitates a more integrated approach to maritime security, involving enhanced intelligence sharing between nations and the development of robust counter-drone measures. Data-driven risk assessments, utilizing real-time ocean intelligence and integrated data ecosystems, will become increasingly crucial for anticipating and mitigating potential threats. The ability to calibrate security responses based on empirical data and longitudinal trends will be paramount in protecting critical infrastructure.
Looking ahead, the question isn’t *if* similar attacks will occur again, but *when* and *where*. The proliferation of drone technology and the increasing geopolitical tensions in key maritime regions suggest that this is likely just the beginning of a new era of maritime risk. The challenge will be to adapt quickly and effectively, leveraging technological innovation and fostering global collaboration to safeguard the vital arteries of global trade and energy supply. The long-term impact on insurance premiums, shipping routes, and the overall cost of LNG will require careful monitoring and proactive risk management strategies.


Egypt’s Damietta Port Authority has refloated the LNG floating storage and regasification unit (FSRU) Energos Winter and moved it to an anchorage about 10 nautical miles from the port after a 14-hour salvage operation with SMIT Salvage.
The Marshall Islands-flagged vessel was damaged in a drone strike at Damietta on July 29.
The attack caused an explosion and fire on board, which also spread to the nearby LNG carrier GasLog Salem. Both fires were brought under control and no deaths or injuries were reported.
Energos Winter later ran aground outside the port’s entrance channel. Egyptian authorities confirmed that the incident was caused by a drone strike but have not identified who was responsible.
Six tugs used in the refloating
SMIT Salvage prepared a technical plan for the operation after inspecting the vessel and carrying out engineering calculations using vessel data.
The refloating work took place on Aug. 6 in rough sea conditions. Capt Yasser Abdel Latif Ahmed and senior port pilots boarded the vessel to help coordinate the operation.
The first attempt used four tugs: the 70-tonne-bollard-pull Fahmy and the 60-tonne Hedaya, Saleh and Suleiman.
Energos Winter also released ballast to reduce its draft. The tugs were able to move the vessel, but could not completely free it from the seabed. Strong winds and the vessel’s exposed hull area of about 5,000 square metres made the operation more difficult.
Two more tugs, the 60-tonne Hamza and 50-tonne Abu Zeid, were then added. This increased the combined nominal bollard pull of the six tugs to 360 tonnes.
The salvage team changed its approach and pulled Energos Winter astern, at a right angle to the navigation channel. The bow was kept pointing north to prevent the vessel from moving towards shallow water.
The change worked and the FSRU was freed from the seabed.
Vessel moved to offshore anchorage
After being refloated, Energos Winter was towed at about three knots for roughly five hours to a designated anchorage around 10 nautical miles from Damietta.
The vessel anchored at about 20:00, and the operation was completed at around 22:00, about 14 hours after it began.
On July 29, the day of the drone attack, Energos Winter had left its berth in the inner harbour at about 14:00 before running aground just outside the entrance channel.
It was roughly 1,000 to 2,000 yards offshore. The grounding was not made public at the time and its cause was not disclosed.
The Damietta Port Authority and the vessel’s owner later brought in SMIT Salvage to carry out the refloating and towing operation.
Energos Winter LNG capacity
Energos Winter is owned by U.S.-based Energos Infrastructure and managed by Singapore-based Wilhelmsen Ship Management.
The FSRU can store 138,250 cubic metres of LNG. Energos Infrastructure develops and operates floating LNG import, storage and regasification infrastructure and has a fleet of 13 LNG infrastructure vessels.
