Only in that it seems likely to have been supplied - most likely by H&C - for use at the Royal Navy's fleet refuelling station at Hoy, Orkneys.
Probably used to move around whatever stuff that big crane was out there to lift. It was a naval fleet refuelling station.
An enquiry to the visitor centre might yield more information?
However thee was a great deal of activity at Lyness Naval Base - construction and laying of submarine nets, torpedoe filling, fuel storage and more. Here is a photo suggesting three cranes were in use at the boom yard (net construction):
The info in the Orkney's Railways link above seems to have been taken from this article in IRS, which lists locomotives and cranes but sadly not rolling stock:
Orkney is well worth a visit, plenty to see and do and eat. There are also some narrow gauge survivors, which when I was there in the late 90s were taken outside for display during summer. Not sure how they run the museum now, I should go back and find out.
I am not sure which year these were taken but Britannia was at Thurso/Scrabster on her last tour.
