The SSH Controllable Buoyancy Solution was invented by company founder, Phil Pritchard, in response to the increasing challenges and opportunities identified within the offshore oil and gas, renewables and salvage industries. It has been brought to life, and to market, through the collaboration of industry and academia and with the benefit of Innovate UK grant funding. 

We have successfully taken the initial concept through a number of technical challenges and delivered a working prototype system which provides the platform for developing and delivering a range of novel lifting systems and solutions.

The company enjoys the protection of a number of globally granted patents.

Inventor of CBS and founder of the company. After graduating from university Phil assumed a career as freelance IT Consultant undertaking contracts with large, “blue chip” clients throughout Europe and the Middle East. Latterly, he became interested in the potential of applied buoyancy after reading an article in the Financial Times on sunken wrecks. He successfully created and led the collaboration of leading industry and academic partners who brought his invention to life, and which now provides for the foundation for the company’s supply chain. His ambition is for Smarter Subsea Handling to become the supplier of choice of subsea heavy lift systems and services to offshore contracting companies.
