Ouest Sécurité Marine, ensuring safety for all mariners

For 15 years, Ouest Sécurité Marine has been providing know-how and expertise in maritime safety for the protection of mariners.

We focus on the safety of mariners

Ouest Sécurité Marine was created in August 2007 further to the merger of maritime cooperatives specialised in liferaft maintenance activities. Since then, OSM has continued to grow by diversifying its strategic areas of activity: overhaul, trading, installation, training and by increasing its territorial presence (6 service centres on the Atlantic coast).

This growth was achieved based on two major assets: support of the French maritime cooperation and a major partnership with Survitec Zodiac, the world leader on the market.

Data from the Institut Maritime de Prévention (French maritime security institute) show that the mortality rate in the fishing sector is 7.2 times higher than in the construction sector with 7.24 deaths per 10,000 fishermen per year.

“It is the responsibility of Ouest Sécurité Marine to provide appropriate solutions and guarantee safety for all those who live by and from the sea.”

Our sectors of activity

At sea, it is mandatory to comply with safety standards.
Ouest Sécurité Marine is present in several sectors to guarantee the safety of mariners.


Ouest Sécurité Marine equips seafarers sailing alone or with a crew, in order to guarantee a maximum level of safety during fishing operations.

Passenger transport

There are many safety issues in the passenger transport sector. Ouest Sécurité Marine ensures maritime security for passenger boats.

French Navy

They look after our safety, we look after theirs! Ouest Sécurité Marine provides on-board liferaft maintenance services complying with a high level of operational requirements for the French Navy.


Ouest Sécurité Marine is a major partner for the State and our administrations. Customs, Maritime Affairs, Gendarmerie, Phares et Balises (Lighthouses and beacons), SNSM (French lifeguard and lifeboat institution), firemen: they trust us all year round.

Service ships

Our ports are the entry points for part of the international trade. We work with all port professionals: mooring, pilotage, towing, dredging, bathymetry, etc.

Shipping companies

The many sea workers in the sector perform a wide variety of jobs. From diving clubs to wind farm maintenance vessels, and nature conservation associations, they all trust us with their equipment.


Nothing beats a grand boat. We work with shipyards to design and integrate the liferafts and lifesaving equipment, so that distress situations at sea can be anticipated before the hull even touches the water.

Offshore racing

High-tech boats, pushed to their maximum performance, far from the coast: we are at the skippers’ side to tackle any difficult situation.

Leisure boat owners

Ouest Sécurité Marine services survival equipment for leisure boat owners: liferafts, lifejackets, suits, beacons. Skippers deal with their shipchandler or directly with us, we work behind the scenes, at your side.
