At OBS Technology we enjoy solving problems for our customers.
OBS Technology have collocated R&D, design and engineering, prototype workshop and test facilities. This enables fast turnaround from initial idea through prototyping to initial testing. A motivated, flexible and highly skilled team in a positive, supportive and inclusive work environment provide the basis for our innovative company culture.
Our test facilities are located in a separate 100 m2 building. The facilities are equipped with systems for a variety of pneumatic and hydraulic test purposes with integrated possibilities of measuring and logging a wide range of parameters.
Operating hydraulic systems subsea, especially at depth, requires the hydraulic energy to be stored in accumulators. These employ the compressibility of gas as energy storage. However, the compressibility of most viable gases is reduced at elevated pressures thus requiring larger accumulator volumes at deeper waters. In addition, accumulators need to be pressurized to a significantly higher pressure than the actual requirement of the hydraulic system as any consumption reduces the pressure in the accumulators.
The DGP concept works with the ambient pressure instead of against it. Energy is stored by creating a volume of void at near vacuum and subsequently exploiting the differential between the ambient pressure and the void to provide hydraulic energy. Key components such as a pump to create the void and an intensifier pump to amplify the pressure has been developed and is presently under test.
