In order to perform ocean-bottom seismographic observations around the Japan trench, new pressure vessels were designed, constructed and tested. One type is for deep ocean-bottom operations at depths in excess of 6000m. The other type is for a monthly operation on the shallow sea-bottom at depths of about 2000m.
