A view of Smiths Dock at North Shields, sent to me by Kevin Blair. No date on the photo so not sure whether it might actually have been A&P at this stage.
RFA Tidepool, in steam, is inboard of Lloydsman well illustrating how large a tug she was. Maybe she is involved with the rig on the left.
Tidepool A76 and sister Tidespring A75 both out of Hawthorn Leslie, were the first RFA's designed to carry a helicopter, Wessex, complete with 2 hangars and ample flight deck. The vertrep, vertical replenishment, now became a common practice.
