Energy Construction Vessels (ECVs)


A new generation of ECVs built to take on a versatile range of renewables infrastructure operations.

Our two ECVs, currently under construction for delivery in 2028, bring together precision and versatility, delivering a new level of capability to a wide range of subsea and infrastructure projects.


Designed to support complex operations, our ECVs enable seamless execution of tasks across the full renewables infrastructure project lifecycle, including:


  • Cable (power and  data) inspection, maintenance & repair work​
  • Cable lay (power and  data) with varying work scope modes​
  • Subsea installation via crane​
  • ROV launch and recovery​
  • Offshore crane lifts​
  • Walk-to-work project support


This adaptable platform ensures reliable performance no matter the mission scope.

Our ECVs maintain the mobility and fuel efficiency of a smaller vessel, while the hybrid battery system enables cleaner operations and enhances overall operational performance.

Crew Transfer Vessels (CTVs)


The global leader in the Tier-1 24-PAX CTV market, with one of the world’s most environmentally advanced fleets.
