Mariners are advised that from 8th April 2024, structural repair works are due to commence on Bullhole Berthing Structure in the Sound of Iona. This will include the use of divers for underwater repairs. Works are expected to complete in 3 weeks, weather permitting.


Works will be undertaken by the workboat “Port Servicer” pictured below. There will also be a small safety boat in attendance. The vessel will maintain a listening watch on VHF CH 12 and will display an Alpha Flag during diving operations.



While works are ongoing, mariners navigating in the vicinity of the Bullhole Berthing Structure are requested to do so with caution, regulate their speed to minimise the effects of wash and stay well clear.

Unless otherwise promulgated, if this NTM is still marked as ‘Active’ it remains in force.

Further details can be obtained using the contact details below.
