«We are proud to announce that the shipbuilding contract for the construction of the TSV Avra, a next-generation Trenching Support Vessel, has been officially signed. The Avra will raise the bar for trenching capability in floating offshore wind and subsea cable industries, while setting new standards in sustainability.
The shipbuilding contract was signed during a ceremony held at our headquarters in Elefsina, Greece. This milestone marks a strategic collaboration with China Merchants Heavy Industry (CMHI) Shenzhen Shipyard for the vessel’s construction, while delivery is estimated approximately in the end of 2027.
The Avra will be the second new building vessel announced in just a few months, following the recent reveal of our newest Cable Laying Vessel Althea, underscoring a period of significant strategic investment and fleet expansion for the company.
More than just another addition to the fleet, the Avra is a game-changer. A double-redundant DP-2 unit with a record-breaking 24 MW of installed hybrid power, she solidifies her position as the most powerful purpose-built TSV to date, engineered to handle the most complex projects in the harshest environments.
What Truly Sets the Avra Apart:
While versatile enough for cable repair and laying, Avra’s primary mission is to set new standards for trenching operations. Her powerful propulsion system is designed to support the operation of a pair of the most advanced trenching vehicles simultaneously, even in adverse weather conditions, thus accelerating project timelines and ensuring operational reliability.
Key Market Differentiators:
The Avra represents a cornerstone of Asso.subsea’s fleet expansion, directly addressing the increasing demands of global offshore energy infrastructure projects.»

Key Market Differentiators:
- Unrivalled Power & Capacity: With 24MW hybrid power and over 180T bollard pull, Avra is designed to operate with heavy trenching, ploughing and boulder clearance tools simultaneously, maximizing efficiency.
- Multi-purpose capability: With a 4,000t under-deck cable carousel capability and twin working decks, Avra can support a wide range of projects including dynamic cable spreads, floating wind installations, inter-array and export cable operations with maximum efficiency.
- Designed for Energy Transition: Methanol and bio-fuel ready, equipped with a large battery hybrid system and cold-ironing capability, reducing her environmental footprint from day one.
- Full Operational Scope: With extensive deck machinery, including a 150t offshore/subsea crane and dual heavy-duty A-frames, is positioned as a multi-role powerhouse, supporting the entire lifecycle of subsea energy projects.
