The wreckage of the Super Puma helicopter which crashed off Sumburgh on Friday will be brought to Lerwick tonight.
The aircraft’s remains will be taken by the salvage boat Bibby Polaris to Lerwick Harbour in time for it to be transported to Farnborough for accident investigators to analyse.
It comes as the investigation surrounding the disaster in which four people died continues.
Detective Superintendent Malcolm Stewart, who is leading the enquiry, said: “This investigation involves a number of officers from across Scotland and we currently have a team of 25 officers conducting enquiries in Shetland, with a similar number carrying out enquiries in Aberdeen.
“A number of resources from across Scotland have had to be deployed and there remains a large amount of complex and sensitive work to be carried out.
“In terms of the enquiry, officers are continuing to trace, interview and take statements from a large number of individuals, both on and offshore and this evidence will form an integral part of the ongoing investigation.
“In addition, family liaison officers continue to support the families of those who died.”
