Marine order 12—Construction—subdivision and stability, machinery and electrical installations

Marine order 12 implements internationally consistent standards for construction of vessels in relation to: 

• subdivision and stability
• machinery and electrical installations.

It also sets the additional requirements for Regulated Australian Vessels that are offshore supply vessels.

International vessels visiting Australian ports may be subject to a port State control inspection to ensure they meet these standards.
