Question 985 Deck Safety

The correct answer is C) 53. According to international regulations, tank ships of 500 gross tons or more on international voyages are required to have facilities to enable a connection on each side of the ship for the ship's manifold (item 53 in the illustration). The manifold is the piping system used to load and unload cargo on a tanker. This requirement ensures the ability to quickly and safely connect cargo transfer equipment during port operations. The other answer choices are incorrect because they represent different components on the ship, such as the accommodation ladder (item 51), the gangway (item 19), or the pilot ladder (item 54), which are not specifically required for the cargo handling systems on large tankers.
