Ports: Three “suitors” claim the drilling base in the Ionian Sea

The selection of a support base for offshore drilling in the Ionian Sea is not a routine port activity but a project of high added value.

In practice, it represents a form of “hidden value,” often proving as significant as the extraction activity itself, as the development of such operations is accompanied by an extensive ecosystem of supporting services, ranging from specialized engineers and geologists to shipping, port and industrial infrastructure. Logistics, technical support and maintenance services also play a critical role, alongside a range of essential functions such as towage, anti-pollution and safety services, as well as provisioning, catering and personnel accommodation, all of which ensure the uninterrupted and safe execution of operations.

Beyond the energy output, the real economic footprint lies in port management and in the broader service network that will develop around the drilling activity, including logistics support, crew transportation, equipment maintenance, and materials storage and handling. As market sources noted, the port ultimately selected will not merely serve a supporting role but is expected to evolve into a fully-fledged energy hub. In this context, three ports in Western Greece—Patras, Igoumenitsa and Astakos—are competing to host the base.

Each offers distinct competitive advantages, ranging from connectivity to international networks to industrial infrastructure and geographic proximity to prospective reserves.

It is also noted that the project’s ownership structure, initially comprising 75% Energean Hellas and 25% HELLENiQ Upstream, is being reshaped following a farm-in agreement, with ExxonMobil acquiring a 60% stake, Energean 30% and HELLENiQ Upstream 10%.

Energean will retain the role of operator during the exploration phase, while, in the event of a commercial discovery, ExxonMobil is expected to assume responsibility for the development phase.
