Question 333 Deck General

The correct answer is D) 50 psi. According to the International Convention for the Safety of Life at Sea (SOLAS), a cargo vessel of 1,000 GT or more operating on an international voyage is required to have a minimum pitot tube pressure of 50 psi from the two highest fire pump outlets when operating simultaneously. This requirement ensures that the vessel has sufficient water pressure and flow to effectively fight fires on board. The other answer choices are incorrect because 70 psi (A) and 100 psi (B) are higher than the SOLAS requirement, while 35 psi (C) is lower than the minimum pressure needed for effective firefighting on a large cargo vessel.
