How many P-100 pumps are on board?

The correct response is based on the standard practice in naval engineering where P-100 pumps, which are portable and diesel-driven, are typically included for emergency dewatering and firefighting operations on board vessels. The presence of five P-100 pumps on a ship ensures that there are sufficient resources to handle multiple scenarios simultaneously, thereby enhancing the safety and operational capability of the vessel in emergency situations. Having this number allows for redundancy in case one or more pumps become inoperable, ensuring that the ship can effectively manage flooding or provide firefighting support as needed. The choice of five aligns with operational and safety protocols typically employed in maritime practices for effective emergency management.
