The doors shall be classified into groups according to their area of application, as follow: Group A´watertight doors in the bridge front bulkhead and the unprotected bulkhead of deckhouses/superstructures, and deckhouses that enclose machinery openings; Group B´watertight doors in the deckhouse bulkheads partially protected or in the bulkhead of deckhouses/superstructures, and not around machinery openings, watertight and airtight doors below weather deck; Group C´airtight /gastight doors in the aft end bulkhead of the bridge, forecastle, and deckhouses at the weather deck level; and Group D´weathertight doors in the deckhouse above the weather deck level.
