Reminders of the skillful work, once common place, now almost forgotten:

Two drawings of a Liberty ship engine. Originally designed by North Eastern Marine, the design was taken to America by Harry Hunter of NEM who, with Cyril Thompson from J.L.Thompsons, presented the design to the United States Maritime Commission in October 1940. The original ship plans that Cyril took were those of the Empire Wave but on 16th November the Admiralty sent a telegram to Cyril and instructed him that the ship size was to be increased and this is when the Empire Liberty design was commissioned as the basis for the Liberty ship. The North Eastern Marine engine was the one used in Empire Liberty.
Returning to England on the Western Prince, the ship was torpedoed on 14th, 250 miles south of Iceland and sank (by u96 commanded by Kovettenkaptitan Lehman- Willenbrock). The survivors in lifeboats were picked up by Hogarths Baron Kinnaird.
The Captain of the Western Prince, nine crew and six passengers were lost.

"Those were the days my friend, we thought they'd never end......." but now we really are history. Swans, just one of the outstanding shipbuilding and engineering concerns on the Tyne. Who can remember ships two or three abreast at Palmers and leaning over the handrails before daylight in winter and the whole river lit up by ships and shipyards. No body really objected to the din or all the buzzers signalling the start of the day's work. The noise meant work and work meant money in the days when money had to be earned. Who now cares about the thousands of skilled men that made flat steel into thousands of ships, those that outfitted them and those who drew the plans and designed them. Salt of the earth.

Not strictly North East Maritime but the Doxford connection is there and there might by some Swires men about. Its 58 years ago this week. The ship is the Scotts built Taiyuan for Swires (China Navigation), with it's Doxford 67LBD5CS engine, yard and engine number 725. On 5th Dec. 00.07 hrs, in Sydney, the 3rd engineer started the engine for the beginning of the voyage when he heard a loud thump in the vicinity of no2 cylinder. Water was seen coming from the piston rod gland drain cock, but when the upper piston was removed only the lower piston crown was filled with water and no evidence of where it came from. The hydraulic lock caused a crank web shrink to slip by 5/8" (16mm). There was no other visible damage and on 13th December Cockatoo Dry dock agreed to attempt the repair. Brine was piped through the journal until it was minus 25 degrees F. Three torches were used to heat the web which was under the load of jacks. After 20 minutes the web jacked back into alignment. Unfortunately it wasn't exactly right and had to be done again. A misalignment of 14 thousandths and seventeen thousandths of an inch was accepted on number 2 and 3 journal respectively. After a quay trial, the ship then had a sea trial on the 28th then sailed on the 30th December. The Superintendent engineer was J.C. Murie and the chief engineer was J.W. Hawkrigg. With the detailed description came this lovely hand drawn sketch which is just too big to scan on my A4 scanner. The sketch isn't signed. the quay trial revealed the source of the leak was a cylinder lubricator injector quill.

It is indeed, the figures look like they have come from a Lowry painting!
Cheers, George
