Designed by EFINOR SEA CLEANER, theUSV (Unmanned Surface Vehicle) Sea Cleaner is a modular, autonomous maritime drone designed to meet the major environmental challenges of our time.
Made from robust, lightweight aluminum, it can be used in harbors, coastal areas and offshore, with optimum efficiency in the face of marine pollution.
Its mission: to actively contribute to a cleaner, safer maritime future.
The USV Sea Cleaner is a truly multi-mission tool. Thanks to its modularity, it can be equipped with various interchangeable modules adapted to the needs of public and private players:
Versatile and twin-engined, it navigates in both directions, and can be remotely operated on sight, by remote control or autonomously. Its detection and navigation capabilities enable it to comply with international regulations (Colreg).
Every year, over 8 million tonnes of plastic end up in the oceans. Hydrocarbons also continue to threaten biodiversity and the environment.
The USV Sea Cleaner provides an agile, fast and effective response to these challenges: compact, mobile and easy to deploy, it enables a concrete reduction in the environmental impact of maritime activities.
The USV Sea Cleaner meets the needs of :
A subsidiary of the EFINOR group, a recognized specialist in the nuclear, defense and shipbuilding industries, EFINOR SEA CLEANER focuses its expertise on the protection of marine environments and the ecological transition.

Commissioned for use by the Grand Port Maritime de Marseille (GPMM), the 100% electric pollution control vessel developed by EFINOR Sea Cleaner is fully in line with the strategy to decarbonize port activities.
After nearly two years of operation, the teams have embarked on a structured operational monitoring process in direct contact with users in order to capitalize on feedback from the field.
This approach aims to gain a better understanding of the actual operating constraints, everyday conditions of use, and operators' expectations in a complex and highly demanding port environment.
EFINOR Groupe M shipyards will participate in EUROMARITIME, a major event for players in the maritime economy, which will be held from February 3 to 5.
On this occasion, the group will exhibit at the Normandie Maritime stand (Hall 1 – G83) and present its full range of expertise in workboat construction, environmental solutions, and naval engineering.
