While in transit, the DEEP DRILLER suffers flooding in the port pump room. Both port bilge pumps are inadequate to dewater the pump room. You may supplement the bilge pumps by using the __________.
• Bilge and ballast systems layout on mobile offshore drilling units (MODUs) • Use of crossover systems to move water between port and starboard systems • Limitations of pumps dedicated to specific services (saltwater service, drill water, ballast)
• Think about which pump(s) are normally connected, through valves and piping, to spaces like pump rooms and bilges—rather than just to cargo or drilling systems. • Ask yourself: if the entire port side bilge capacity is inadequate, what arrangement would let you bring additional capacity from the opposite side into that flooded space? • Consider which choice mentions not just a pump, but also the necessary piping arrangement to reach the flooded port pump room.
• Check which pumps are normally lined up to handle bilge/ballast transfers rather than process or drilling fluids. • Verify which option provides both a pump and a means of connection to the port side system. • Confirm that the selected system can legally and practically be used for emergency dewatering of an internal space.
