The Marine Management Organisation (MMO) has announced the resumption of its Inshore Vessel Monitoring System (I-VMS) programme, confirming a renewed partnership with CLS UK Ltd to complete the nationwide rollout of tracking devices for England’s under-12 metre fishing fleet.
The decision marks a significant step forward in the UK’s fisheries monitoring strategy, aimed at improving compliance, spatial planning, and sustainable fishing practices across coastal waters.
New Agreement Secures Replacement Devices for Fishing Fleet
Under the updated arrangement, CLS UK Ltd—formerly known as Fulcrum Maritime Systems Ltd—will supply type-approved tracking devices designed to transmit vessel location data directly to the UK Vessel Monitoring System Hub.
The MMO confirmed that all affected vessels will receive replacement devices at no additional cost, particularly those impacted by previous disruptions linked to SC2 device data transmission issues.
Officials said the move is intended to provide stability to the sector after a period of uncertainty, ensuring continuity in the government’s wider rollout of mandatory tracking technology.
Government Pushes Ahead with Mandatory Monitoring Plans
The resumption of the programme forms part of preparations for upcoming legislation that will make I-VMS devices compulsory for all under-12m fishing vessels operating in English waters.
The MMO stated that the initiative is designed to create a more reliable framework for fisheries oversight, helping regulators better understand fishing activity and strengthen enforcement where necessary.
Authorities say the system will also support long-term environmental goals by improving how marine resources are managed and monitored.
MMO Emphasises Fairness and Industry Cooperation
Speaking on the renewed rollout, MMO Director of Operations Peter Clark highlighted the importance of accurate data in shaping sustainable fisheries policy.
He said vessel monitoring information would play a crucial role in improving compliance systems, marine spatial planning, and sustainable fishing operations across the industry.
Clark added that the organisation values the cooperation of fishermen throughout the transition process, noting that their patience and engagement remain essential as the programme moves toward full implementation.
Enforcement Approach to Remain Balanced During Transition
The MMO confirmed that its compliance and enforcement strategy will continue to be “measured and pragmatic” during the rollout phase.
Officials stressed that fishermen should be able to operate safely and legally without facing unnecessary disruption, confusion, or administrative burden while the system is fully implemented.
The organisation also urged vessel owners not to take any immediate action, including removing or disabling existing tracking devices, as further instructions will be issued directly to those affected.
Support Channels Open for Fishing Operators
To assist with the transition, the MMO has advised fishermen to contact its I-VMS support team with any questions or concerns via email or telephone during standard working hours.
The regulator also confirmed that regular updates will continue to be published on the official government guidance page as more details become available ahead of the full legislative rollout.
