The Ojika-class patrol vessel is a class of PL type patrol vessels of the Japan Coast Guard. [2][1][Note 1]

Design[]

The design of this class is generally an modified version of , a preceding 1,000-ton class PL being emphasis on air-sea rescue operations.[5]

In contrast to the Nojima, which had a helicopter deck one level higher than the strength deck, this class utilizes the end of the strength deck as the helicopter deck, and has a reinforced structure to land a large Super Puma helicopter. In addition, a well dock was installed below the helicopter deck to accommodate a high speed launch,[5] but it was not efficient as planned and discontinued after the second ship.[6]

The chimney was split into two and placed on both sides of the ship. Between these funnels, a hangar for the ROV and a preparation room for diving operations were set up.[6] With these capabilities to support divers, all ships of this class are officially certified as Patrol Vessel with Enhanced Rescue Capability (救難強化巡視船, Kyūnan-kyōka-junshisen).[2]
