Why we do it.

Our objective is to support the subsea working environment by making it less hazardous. We aim to help preclude any loss of life or injury during underwater operations and to prevent harm to the environment both subsea and otherwise. With every product we design, testing exercise we undertake or customer we serve, safety and the mitigation of risk is of the utmost importance.
