SES-X Hull Technology Concept

The patented SES-X hull technology significantly reduces energy consumption and CO2 emission compared to conventional hulls. The unique solution is a combination of catamaran and monohull, gaining the upside from both. Increased comfort and incomparable seakeeping capabilities are additional benefits. The technology is compatible with conventional propulsion systems.

International Patented Hull Technology

SES-X hull is the next generation Surface Effect Ship (SES) solution, introducing an air cushion between the water and the vessel

IMPROVED ENERGY EFFICIENCY

The air cushion lowers the wet surface area of the hull which reduces water friction – enabling high speed and zero emissions

REDUCED WAKES

The vessel is lifted out of the water and has a very low draft, which reduces wake wash – often being a problem in protected/inland waters

IMPROVED COMFORT

The air cushion acts as an air damper, improving comfort by less wave-induced motions, enables higher speed in rough waters

Superior energy efficiency

UNIQUE HULL SOLUTION

The SES-X hull is a combination of several current vessel types – having the stability and deck space of a catamaran, the hull volume of a monohull, and the seakeeping and efficiency of a hovercraft.

SIMPLE BUT EFFECTIVE TECHNICAL SOLUTION

The solution is essentially a regular v-shaped hull, with a hollow bottom section, a rear enclosing flap and an air fan in the bow. Compared to regular SES technology, SES-X solution does not include problematic and high-maintenance “skirt” enclosing the cushion. Compared to hydrofoils, SES-X solution is simpler, safer and more robust. Off-cushion, the vessel operates essentially as a regular monohull.

INTRODUCING SUSTAINABLE SOLUTIONS TO THE
HIGH-SPEED DOMAIN

For conventional vessels, the water resistance and fuel consumption increase exponentially with speed. This has resulted in that zero-emissions vessels typically have only been available for slow-speed vessels. SES-X opens up for zero-emissions also for high speed vessels with game-changing energy efficiency and simplicity.
