Lifeboat crews were called out over fears there was a person in the water close to the harbour – only to discover it was a buoy.
RNLI Aberdeen lifeboats the Bon Accord and the James Bisset Simpson were launched after a member of the public reported spotting a person or object in the water in the Bay of Nigg.
Coastguard UK passed on the call which came in at around 10am yesterday, and the lifeboats were launched at 10.20am.
The object was seen at the entrance of the new Aberdeen Harbour Expansion project, south of Girdleness Lighthouse.
Crews were stood down after it was discovered that the incident was a false alarm, and that the item was actually a mooring buoy.
A spokesman for the UK Coastguard said: “The call came in at about 10.12am and essentially lifeboats were sent out to identify the object.”
Nine volunteers took to the all-weather and inshore lifeboats and set off to answer the call.
The caller stayed on the phone and guided the inshore lifeboat directly to the object which had sparked their concern.
Crews were able to identify the object as a mooring buoy.
Coxswain Robbie Coull said: “It was helpful that the caller stayed in position and on the phone: this allowed us to confirm positively that the object seen was in fact the buoy.”
The call was Aberdeen’s 22nd launch on service in 2018 and has been classed as a “false alarm with good intent”.
The lifeboat crews were stood down at 11.30am.
Meanwhile, Aberdeen Lifeboat crew recently joined forces with Aberdeen Coastguard Rescue Team to practice some core skills.
The coastguard team received a lecture from Aberdeen’s Lifeboat training co-ordinator on mooring and berthing before being given the opportunity to practice tying up the all-weather lifeboat in a range of different scenarios around the Granite City’s harbour.
For the final part of the training, the coastguard team went out in the Severn class lifeboat and had the chance to experience things on “the other end of the radio”.
