What We Do

ESNA is an independent ship design company for high-performance vessels. We specialize on air cushioned catamaran/Surface Effect Ships (SES), where we have unique world-leading competence.

Our strategy is to complement yards with design packages and the special air cushion systems and equipment, allowing any yard to build safe, cost efficient and reliable Surface Effect Ships.

We operate at the crossroad between advanced military and commercial high-speed craft technology, and the markets for offshore renewable energy and maritime operations. 

Who We Are

The founders have more than 40 years extensive experience with design construction and operation of Surface Effect Ships.

Our main advantage in the high-speed ship market is our employee’s unique experience, competence and enthusiasm for innovative naval architecture, and a great network of cooperation partners and suppliers. ESNA can deliver vessel designs that will be fit for purpose for many years to come. 

Our Vision

We believe in a close cooperation with all stake-holders when designing vessels. That includes the customers, ship-owners, vessel operators, shipyards, classification societies, flag states and suppliers.

We are enthusiastic about state-of-the art vessel solutions and technologies and are dedicated to find the right solutions for our customer: Cost efficient and fit for purpose solutions, tailored for their requirements.
