UK general exemption for ROUVs between 2.5 and 4.5 metres

The UK Maritime and Coastguard Agency published Maritime Guidance Note (MGN) 705 introducing a new General Exemption specifically for Remotely Operated Unmanned Vessels (ROUVs) that are between 2.5 metres and less than 4.5 metres in overall length. This exemption permits eligible vessels to operate without requiring certification from the Maritime and Coastguard Agency (MCA) or its authorized delegates, provided they meet certain conditions. The exemption aims to simplify regulatory requirements for smaller unmanned vessels and came into effect on 31 December 2024.

Applicability and Scope

This exemption applies to ROUVs, defined as vessels operated remotely with no crew on board, that fall within the specified size range. It offers a streamlined process for compliance, ensuring proportionality in regulations for smaller vessels while maintaining safety and operational standards.

Background and Existing Pathways

Before the introduction of this exemption, operators of ROUVs under 24 metres in load-line length had three main regulatory pathways:

1. MGN 702: A General Exemption for ROUVs under 2.5 metres in length, allowing them to operate without MCA certification.
2. Case-by-case assessments: Vessels could apply for Load Line Certification through the process outlined in MGN 664.
3. Workboat Code Edition 3 certification: ROUVs under 24 metres could undergo surveys and obtain certification under this code.
