Morphology

patrol + ship

The meaning is directly and transparently derived from combining 'patrol' (an activity/unit that monitors or guards an area) with 'ship' (a vessel); together they denote a vessel used for patrol duties. This noun–noun composition follows common patterns (compare 'patrol boat', 'patrol car') and is likely immediately comprehensible to a B1 learner who knows both words.

Etymology

Patrol ship: The compound patrol ship names a ship which 'patrols', moving along an area to watch and guard it. Imagine a small boat sailing slowly along the coast with crew looking for trouble; that image explains why the phrase means a boat sent to monitor and protect a place.
