Which I-VMS devices are approved?

MMO commissioned independent tests in 2022 in response to concerns that type approved devices did not meet the agreed specifications. On conclusion of those tests, two devices remain type approved: the Fulcrum NEMO and the Succorfish SC2. 

No other vessel monitoring device should be purchased or installed, and no other vessel monitoring devices will comply with the requirements of the statutory instrument (due in 2024) applying to English waters.

A plan has been developed to support those yet to purchase a device and those that purchased a device that is no longer type approved to obtain their choice of type approved device.
