Whessoe S.A., based in Calais, France, was founded in 1961 by Whessoe Plc., a UK based holding company, focusing on heavy engineering and tank gauging instrumentation and safety systems.
In 1991, the heavy engineering division, today known as “WHESSOE Oil & Gas”, was split off from Whessoe Plc and has continued under various different ownerships, today being the Saudi Arabian AL RUSHAID GROUP division.
Therefore, Whessoe S.A. is NOT related to the engineering & construction company known as WHESSOE Oil & Gas Ltd.
Since the earliest days of liquid gas storage, Whessoe S.A. has been at the cutting edge of technological development of instrumentation and safety shut-off valve systems for LNG and LPG storage, ensuring that all hazardous aspects within the industry are known and controllable. In close cooperation with leading gas companies, new technologies have been developed and extensively tested for endurance, accuracy and reliability in the harsh environments, associated with liquid gas storage. Our highly accurate instrumentation, control platforms and safety shut-off valve systems are installed worldwide to help protect investments in personnel, environment, equipment and product.
