The Ojika-class patrol vessel is a class of PL type patrol vessels of the Japan Coast Guard. [2] [3] [Note 1]

Design

The design of this class is generally a modified version of Nojima (PL-01), 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]
