The main function of the JIS F2017 Panama Chock is to guide the mooring ropes on large vessels during the mooring process. It helps to ensure the safe and efficient connection of the ship to the mooring facilities, bearing the huge loads exerted by the mooring ropes.

Deck-mounted types (AC/AP) are installed on the deck. Type AC is made of cast steel and is often supplied with a base plate to be bolted to the plinth. Type AP is made of steel plate. Bulwark-mounted types (BC/BP) are installed on the bulwark. Type BC is made of cast steel, and type BP is made of steel plate. Their installation locations and manufacturing materials for different subtypes are the main differences.

Generally, the standard materials are as per JIS specifications. However, in some cases, if there are specific requirements, manufacturers may be able to provide customized materials. But this would need to be discussed with the supplier in advance, and it may also affect the cost and delivery time.

Sandblasting to level 2.5 removes rust, dirt, and other impurities from the surface of the chock, providing a clean and rough surface for better adhesion of the primer. The shop primer then forms a protective layer, preventing the chock from corrosion caused by seawater and other harsh marine environments, thus extending its service life.

Yes, there are multiple nominal sizes available, including 310mm, 360mm, 400mm, 450mm, and 500mm. Each size has specific dimensions for different parts of the chock to suit various vessel sizes and mooring requirements.
