Summary

  • PISCES Cable System Limited has been formed by Equitix, McMahon Design and Management (MDM) and Orange to deliver a planned subsea system connecting Galway with Saint-Hilaire-de-Riez, Sopelana and Carcavelos across Ireland, France, Spain and Portugal.
  • The project is currently reported at approximately 3,125 km and 16 fibre pairs. The marine route survey was completed in August 2026, while engineering and permitting are underway and deployment is expected in 2028.
  • Those milestones establish delivery progress, not a functioning route. Construction approval, completed landing and backhaul, contracted capacity, service availability and proven route diversity remain unestablished by the evidence.

PISCES has crossed an important institutional threshold. On 14 October 2026, Equitix, MDM and Orange announced the formation of PISCES Cable System Limited, a joint venture established to deliver the project, with Carine Romanetti appointed chief executive. The system is planned at approximately 3,125 km with 16 fibre pairs. Its intended landing points are Galway in Ireland, Saint-Hilaire-de-Riez in France, Sopelana in Spain and Carcavelos in Portugal. Orange plans a new landing station at Sopelana.

The delivery model is more developed than the project was at its earlier preparation stages. Investment is being made through Equitix Infra Ireland, Equitix's Irish greenfield infrastructure fund, whose anchor investor is the Ireland Strategic Investment Fund, alongside Equitix, Orange and MDM. The announcement establishes a financing and delivery structure, but it does not disclose total project capital expenditure, partner ownership percentages or individual capital contributions. Those figures should not be inferred from the existence of the joint venture.

The physical preparation has also advanced. Elettra Tlc and Orange Marine completed the marine route survey in August, according to the joint-venture announcement. Engineering and permitting are now underway, and the project is expected to be deployed during 2028. The European Commission's March 2026 project description had characterized PISCES as approximately 3,000 km with a planned 16-fibre architecture and an open-access model. It also described SMART monitoring capabilities as subject to assessment or planning.

Those capabilities therefore remain part of the project's stated development scope rather than evidence of an already deployed monitoring system.

The regulatory evidence illustrates the difference between preparation and authorization. An Irish Maritime Area Regulatory Authority amendment report concerns the survey activity in Irish waters. Weather delays moved the relevant Irish-waters survey window to 1 February–30 June 2026, while Licence Condition 37(i) restricted permitted activity during that period to limit disturbance to fish spawning. This demonstrates that survey work was subject to defined marine conditions. It does not demonstrate that construction permission has been granted. A survey permit is evidence for route investigation, not a construction approval.

The European Union's financial contribution must be read with the same precision. The European Commission's CEF Digital 2024 award document lists “24-EU-DIG-PISCES Phase 3”, with McMahon Design and Management Limited as the applicant and an award of €18,932,210. The amount is specifically a Phase 3 award to MDM. It is not the total cost of PISCES, not a statement of all EU funding received across every project phase, and not evidence of the private capital split among the JV participants.

The grant establishes support for a defined phase; it does not by itself establish that the complete project financing package is disclosed or sufficient for every subsequent stage.

The commercial proposition is equally clear but still prospective. PISCES is intended to provide a high-capacity, open-access and scalable dark-fibre connection between Ireland and continental Europe. Orange Wholesale describes it as an intended route alternative to connectivity transiting the United Kingdom. That strategic objective matters because the value of an additional physical path depends on whether it can provide customers with a usable alternative when another path is impaired. But the statement of intent is not proof that such route diversity exists today.

The distinction is especially important for resilience claims. A subsea cable becomes an operational route only when the physical marine segment connects into functioning landing infrastructure, terrestrial backhaul, interconnection and customer capacity arrangements. The current evidence does not establish completed landing and backhaul systems, signed capacity contracts or a service date. Nor does it demonstrate that traffic has actually been carried over PISCES. Until those conditions are evidenced, the project should be described as infrastructure moving toward route diversity rather than route diversity already delivered.

The project should therefore be evaluated through separate gates. The first is the existing grant and project-support stage: the Phase 3 CEF award demonstrates EU support for a defined activity. The second is financing: the JV and Equitix Infra Ireland establish a private delivery structure, but the total capital requirement and contribution split remain undisclosed. The third is permitting: engineering and permitting are underway, while the existing marine record concerns survey authorization rather than construction approval.

The fourth gate is construction. Cable deployment must move from preparation into actual installation. The fifth is landing and backhaul, where the marine asset must become part of an end-to-end terrestrial connectivity path. The sixth is capacity contracting and access, where the open-access proposition must translate into capacity that customers can actually procure. The seventh is operational route diversity, where traffic can use the route and its independence from existing paths can be evaluated in practice.

This sequence prevents several different forms of progress from being collapsed into one headline. JV formation is not construction. Survey completion is not a deployed cable. A grant is not total project financing. A permit for survey work is not construction authorization. A 2028 deployment target is not a guaranteed service date. And a planned direct Ireland–continental Europe route is not yet demonstrated resilience.

The 2028 target is nevertheless a useful forward milestone. It provides a timetable against which engineering, permitting, procurement and construction progress can be measured. The appropriate question is not simply whether 2028 remains the stated target, but whether each prerequisite is advancing in a sequence that makes that target credible. A project can remain formally on schedule while a later landing, backhaul or commercial dependency still prevents usable service.

PISCES now has a dedicated delivery company, named leadership, a reported completed marine survey and engineering and permitting activity underway. These are substantive signs that the project has moved into execution. The remaining uncertainty is not whether the project has advanced, but how far the evidence can support claims about the eventual connectivity outcome.

For operators, the practical distinction is straightforward. PISCES should be tracked as a developing infrastructure option, not booked as existing resilience. The decisive evidence will accumulate when construction is authorized and executed, landing and backhaul are completed, capacity becomes contractable, service is activated and actual traffic can use a path that is meaningfully distinct from existing alternatives. Only then can the strategic claim of a new Ireland–continental Europe route be converted into an operational resilience claim.
