B63J AUXILIARIES ON VESSELS
Introduced: September 1968
Description
B63J encompasses auxiliary systems and equipment installed on ships and waterborne vessels to support primary operations. This subclass covers devices for vessel propulsion assistance, maneuvering, stabilization, and onboard utilities such as anchoring systems, mooring equipment, and auxiliary power generation. The classification includes technologies for improving vessel handling, safety, and operational efficiency but excludes primary hull structures (B63B) and main propulsion machinery (B63H), which are classified separately.
IPC and CPC are identically structured here. All 5 subcodes exist in both systems.
3 shared codes have differing titles between IPC and CPC.
