Tuna vessel retrofit.

APINA modernises the refrigeration installation of active tuna and fishing vessels so they comply with the F-Gas regulation, gain efficiency and access the demanding European fresh market.

With more than 40 vessels equipped and 40 years of experience in the sector, we know how to work on an existing installation —in dry dock or in port— while minimising downtime.

We replace obsolete refrigerants with natural refrigerants (ammonia NH₃, CO₂) or new-generation low-GWP freons, compliant with the European F-Gas regulation and the Kyoto protocols. We always start from a prior thermal study of the installation to ensure the change improves performance, not just legal compliance.

We adapt the installation to obtain the classifications required by the classification societies (Bureau Veritas, DNV-GL): approved components, safety logic and documentation. The result is a vessel that returns to the water certified and ready to sell in the most demanding markets.

We pre-assemble as much as possible in the factory to reduce time on board, work in confined spaces and deploy our technical service to any port in the world. A clear roadmap: study, proposal, execution and commissioning.
