An investigation has been launched after video emerged online of two men taking a speedboat underneath two oil rigs at the port of Dundee.
The footage shows the boat travelling underneath the Maersk Gallant and Rowan Norway jack-up rigs in the River Tay.
It breaches the 100metre clearance requirement for the rigs, with the Port Authority confirming it has started an investigation into the “serious incident”.
A spokeswoman said: “Safety on the River Tay is our top priority and there are byelaws in place to ensure the safety of water users.
“A Notice to Mariners was recently distributed stating that 100m clearance from the rig must be maintained at all times.
“We are currently investigating this serious incident at the Port of Dundee and we are in contact with the relevant authorities.”
The notices, issued by Port of Dundee marine manager Paddy Kelsall, state: “Vessels are requested to navigate with due diligence and caution when proceeding within the vicinity of this rig, maintaining a minimum of 100m clearance.”
The video was uploaded on Richy Boag’s YouTube page last Sunday.
The Rowan Norway weighs over 20,000 tonnes, with the Maersk Gallant weighing 15,000 tonnes.
