Nope - Olympus = huge 20000hp plus turbine. Tyne - much smaller engine (~6000hp) used for cruise speeds, because turbines work best and most fuel efficient near their max rating.
T21, T42 and early T22 had 2 x Tyne, plus 2 x Oly. Stooging around? One or two Tyne flashed up. Max chat/release the hounds? Flash up the Oly's.
I posted this in # 17108, above, when the discussion was about fishing:
In the book ‘Hearts of Oak - a collection of Royal Naval anecdotes’ - one CD Stanford (apologies rank at the time not known) tells a dit about the Cod War, entitled ‘Cod War Recovery’.
“HMS Exmouth was on passage to a well earned visit to Liverpool.
Just off the north Wales coast we received a signal to proceed with all despatch to Faslane, offload boats, onload stores and then make best speed to a position south-east of Iceland to replace a frigate badly damaged by a collision with an Icelandic gunboat.
Exmouth was a Type 14 - a small, lightly armed, ASW frigate. She was also the testbed for the marinised Olympus gas turbine engine, controllable pitch propellers, and a new ergonomic Bridge which gave control of everything. She had unique, incredible acceleration and deceleration, unknown in any other warship at that time.
When we arrived on station the score sheet read Iceland 7 UK 0, and we were met by some very battered frigates which had not been designed to act as fenders between trawlers and gunboats. So into the fray.
On the first day ‘Baldur’ closed at speed to see off our diminutive ship. She set up her usual tactic of paralleling course before sideswiping our quarter with her strengthened transom.
We waited until her stern was closing and within ten feet of our side, then went to 100% power on the gas turbine. She was left for dead - confused, bemused and wallowing.
She tried again on several occasions; each time we out-manoeuvred her with ease.
The word soon got round and ‘Thor’, ‘Odin’ and ‘Aegir’ all tried their hands, but to no avail.
Modern marine engineering technology had won the day.”
