GEPS Techno

GEPS Techno was created in 2011 by three founders from the shipbuilding and offshore sectors.

Their ambition: to supply energy offshore, far from the grids, to support development of the Blue Economy.
Their idea: to offer hybrid systems that exploit all the renewable energy resources available at the location in order to solve the challenges of autonomy, intermittency and uneven distribution of offshore resources.
They are creating an agile company capable of both integrating existing technologies and rapidly developing new ones.
In 2012, the first buoy incorporating a unique wave motor system, capable of both producing energy and stabilising movements, was launched.

Test programmes followed and new prototypes integrating and hybridising up to four different sources of marine energy were launched for even greater reliability and autonomy.


Since 2016, GEPS Techno has been developing and optimising anti-roll tank architectures for vessels seeking greater comfort and operability. To date, some thirty ships have been equipped with tanks designed by GEPS TechnoStabInSea was founded in 2022. 

The question of operability arises at the ship design stage where volume is reserved in the architecture for the future integration of one or more tanks.

Based on GEPS Techno’s expertise and tools, StabInSea offers a tailor-made approach for naval architecture offices. The question of operability arises at the ship design stage where volume is reserved in the architecture for the future integration of one or more tanks.

StabInSea offers to support naval architects with a stabiliser design study , both to meet the operability requirements defined in the specifications, but also to limit the volume to what is really useful. Adapted tank shapes can also be studied, in particular to leave free passage (equipment, personnel passage, etc.). The result is a less cluttered, lighter and more efficient vessel.

StabInSea has developed digital tools proven by tank and sea trials.
These tools permit the study of different tank architectures and positions in the vessel or structure, to model open area fluid behaviour and define movement impact on the overall system.
The analysis takes into account the fluid’s non-linear effects and permits the coupling of the {tank+ship} or {tank+structure} system to be established with greater accuracy. Many iterations are possible to seek an optimal solution.



Building on the success of its solutions for vessels, StabInSea also designs passive stabilisation systems for offshore structures.

Several customer studies have shown that free-surface fluid motions can stabilise an FPSOa floating wind turbine, or even the nacelle of a land-based wind turbine. The architectures are adapted to the characteristics of these structures and permit the periods of dynamism to be filtered out.

StabInSea’s digital tools provide the flexibility to study these unique cases.

The expected gains can be truly significant: structure weight reduction, anchoring simplification, production performance enhancement, increase of installation weather window, etc.
