Watertight hatches are required in watertight compartments below bulkhead deck or in a flush execution, which is installed on the main deck. Our watertight hatches are always measured and tested for the required water pressure, and are supplied as a completely finished and tested hatch, ready to be welded in.   The design and manufacture of our hatches are in full compliance with class regulations regarding watertight hatches and can be individually approved by all major classification societies. Which rules and regulations are applicable depends on the type of vessel, classification society and the position on the ship. This is of course based on the assumption that the approved door & hatch plan covers the approval to place this door in that specific position.
