Remotely operated vehicle operation procedures

1 Scope

GB/T 46413-2025 is the Chinese national standard covering operating a remotely operated vehicle - the pre-dive checks and the launch and recovery through the splash zone, the tether management and the umbilical, the pilot's watch, the emergency recovery of a snagged vehicle, and the records of each dive. First edition, in force from 1 May 2026. Issued on 5 October 2025, it has been in force since 1 May 2026.

This document specifies the pre-operation preparation, operation procedures, and emergency procedures for remotely operated vehicles (ROVs). This document applies to underwater operations of remotely operated vehicles (ROVs) in marine fields such as offshore oil and gas, offshore wind power, and rescue and salvage. Other ROV applications... The underwater operation of the watercraft should be carried out in accordance with the guidelines.
