At OBS we enjoy solving problems for our customers.
At OBS, we have integrated our R&D, design, engineering, prototype workshop, and test facilities. This strategic colocation enables rapid progression from initial concept through prototyping to preliminary testing. Our innovative company culture is underpinned by a motivated, adaptable, and highly skilled team, all thriving in a positive, supportive, and inclusive work environment.
Our test facilities are located in a separate 100 m2 building. The facilities are equipped with test systems for a variety of pneumatic and hydraulic test purposes, and with integrated possibilities of measuring and logging a wide range of parameters.
Operating hydraulic systems subsea, particularly at significant depths, necessitates the storage of hydraulic energy in accumulators, which utilize the compressibility of gas for energy storage. However, at elevated pressures, the compressibility of most viable gases diminishes, requiring larger accumulator volumes for deeper waters. Additionally, accumulators must be pressurized to substantially higher levels than the actual hydraulic system requirements, as any consumption reduces the pressure within the accumulators.
The DGP concept innovatively leverages ambient pressure rather than opposing it. Energy is stored by creating a near-vacuum void and subsequently exploiting the differential between the ambient pressure and the void to generate hydraulic energy. Key components, including a pump to create the void and an intensifier pump to amplify the pressure, have been developed.
