Supervising the construction of new Green Hybrid Fish Farming vessels

Between the operating period 2021-2022, INSB Class was entrusted by ALMI Technical Bureau-Greece, with the technical construction supervision and certification of six (6) newly built green hybrid fish farm vessels (AVRAMAR series). The vessels were constructed using a variety of eco-friendly materials including steel and polyethylene. The diversity and quality of the used environmental materials promoted the “hybrid” allocation given to the vessels, allowing them to operate with substantially reduced carbon emissions and environmental footprint.
