Established in 1993 Alkyonis Co. is the result of a nautical family’s passionate work consisting of three brothers, Ioannis, Manolis & Stavros Kouremetis. Their experience in the marine industry traces its roots back to 1959 and “TRITONIS S.A.”, one of the main ship repair companies in Greece. The business continues till today with Alkyonis Co. being the leader in marine insulations. The company performing marine maintenance and repairs, for almost 30 years has expanded well beyond the confines of the shipping industry.


Alkyonis Co. is a premium provider of marine insulation services operating in the commercial marine, defense, yachting, and cruise sectors. Since 1994, we have been proudly serving the Hellenic Navy, being in constant co-operation and accomplishing significant projects and long-term contracts on surface ships and submarines. We also provide teams to attend commercial vessels and yachts worldwide, both on a planned and emergency basis, while our work includes awarded projects.
