A marine underwater energy storage system operates fully when engineers are able to enter the powerhouse to do maintenance on hydro turbines. A submarine must be designed to connect to the energy storage system to transfer people safely. However, the energy storage system is exposed to biofouling which causes high surface roughness over time. The increasing surface roughness has a negative effect on connecting and sealing the underwater energy storage system. The seals are made of rubber and the underwater energy storage system is made of steel on which barnacles and sponges will grow. For perfect alignment and sealing, the barnacles and sponges need to be removed leaving a lower surface roughness. In this study, experiments are taken to investigate the working principle of sealing rough surfaces and to simulate hydrostatic pressures at a depth ranging from 30 to 50 meters. Three different rubber O-ring seals are used and sandpaper is used for replicating the surface roughness. The surface roughness after removing biofouling is found and its effect on different seals. Additionally, the squeezing pressure on the seal is found needed to achieve an acceptable leakage rate.
