Asso.subsea has announced the official signing of the shipbuilding contract for the Andromeda, the next-generation Trenching Support Vessel and sister ship to Avra.
The contract was signed following Asso.subsea’s declaration of an option included in the original shipbuilding agreement for the Avra, further strengthening our strategic partnership with China Merchants Heavy Industry (CMHI) Shenzhen Shipyard. Andromeda will be built at the same shipyard site alongside the Avra and the Cable Laying Vessel, Althea. Delivery of Andromeda is planned for Q2 2028.
Designed as a double-redundant DP-2 vessel with a record-breaking 24 MW of installed hybrid power, Andromeda ranks among the most powerful Trenching Support Vessels ever constructed.
Purpose-built to execute the most demanding trenching, ploughing and subsea intervention campaigns, Andromeda enables the simultaneous deployment of two advanced trenching vehicles, even in challenging offshore conditions, significantly enhancing project efficiency and schedule certainty.
With twin working decks, extensive deck machinery and prepared for a 4,000t under-deck cable carousel, she offers exceptional operational flexibility across dynamic cable spreads, floating wind installations, inter-array, and export cable campaigns.
“The contract signing for the construction of Andromeda reflects our proactive response to the accelerating demand for high-performance trenching solutions,” said Ioannis Togias, Executive Director of Marine Technology. “By declaring this first option and introducing a second vessel with identical capabilities to Avra, we ensure operational flexibility and parallel deployment options for our clients worldwide.”
The Andromeda stands as a cornerstone of Asso.subsea’s long-term investment strategy, addressing the increasing complexity, scale, and urgency of global offshore energy developments.
