INVESTIGATIONS are continuing into the North Sea helicopter crash which claimed four lives - including an oil worker from Moray.
Sarah Darnley (45) was one of those killed when a Super Puma went down off the coast of Shetland on Friday.
The other three victims were Duncan Munro (46), from Bishop Auckland, Gary McCrossan (59) from Inverness and George Allison (57) from Winchester.
A total of 18 people were on board the CHC helicopter - 16 passengers and two crew, which went down off the coast of Shetland shortly before 6.30pm.
Fourteen people were taken to the Gilbert Bain Hospital in Lerwick for treatment, including the two members of crew. Five were discharged and nine detained overnight either for observation or suffering from exposure.
Sarah is survived by her parents Anne and Edmund Darnley, of Elgin, her sister Angela and nephew Nicholas, also of Elgin.
Her mother Anne said: "We are shocked by the sudden loss of Sarah, who was a fun-loving free spirit who will be sorely missed."
Born and brought up in the Elgin area, Sarah attended Elgin High School and moved to Aberdeen when she was 19.
"She enjoyed her job," added her mother. "She had great camaraderie with her colleagues and over the years she made some fantastic friends whom she was able to visit in various parts of the world including South America and Thailand.
"Sarah lived life to the full, she was easy going and a one-off. She will be deeply missed by all who knew her.
Assistant Chief Constable of Police Scotland, Malcolm Graham, said: "Our sympathies are very much with the families of those affected at this difficult time.
"This incident has resulted in a large-scale response from a number of different agencies who have worked closely together to deliver a swift rescue operation.
"We will now be carrying out an investigation to establish the circumstances in due course."
Shetland area commander, chief inspector Angus MacInnes, confirmed the news. He said the operation had been hampered by difficult weather conditions but the recovery was made this afternoon.
Specialist divers were brought in to help with the search and Aith and Lerwick lifeboats have been at the scene again today assisting recovery efforts.
He said: ""The North Sea is an extreme environment which has posed challenges for the recovery operation, not least the weather conditions.
"Friday’s incident has had a huge impact on those who work or have relatives in the oil and gas industries but also the communities in Shetland and Aberdeen. There is a tangible sense of mourning and shock in the area and there is unlikely to be anyone who hasn’t had this on their minds over the last few days.
"The quick and coordinated response by the Maritime and Coastguard Agency (MCA), RNLI and other emergency services may have prevented further loss of life in this already tragic incident.
"The response to Friday’s incident has included hundreds of people from a variety of organisations including the MCA, RNLI, RAF, Police Scotland, the local NHS, local authority and the offshore industry itself.
He added: "In the north of Scotland we have had responsibility for the policing of the offshore industry for several decades and regrettably we have considerable experience and expertise in dealing with this type of event.
"We have well-rehearsed plans in place to quickly respond should the worst happen and the public should be assured that we have made the full resources of Police Scotland available.
"This will continue to be the case as we move forward with our investigation into the cause of this tragedy."
