Don't know how accurate this will be but probably worth a look at.

Mark Fooks, a young OS, one of two who survived the sinking of the POOL FISHER, in November 1979, went to the pool in Liverpool when he was ready to go back to sea, and said , "Give us the biggest ship you have got, the small ones sink under me,"
They gave him the DERBYSHIRE, he and a few others flew to Japan to await the arrival of DERBYSHIRE, she did not arrive, so they flew home again. Lucky a econd time.

This programme was shown on UK TV around November time last year. The ships crew are all portrayed by actors and without giving anything away it is well worth watching.

watched this programme three nights ago, found it to be very well presented and informative. amazing to see the complex equipment used and the clarity of the photos obtained from those depths. if the rest of the series are as well put together as this episode it's going to be a good series.

Hi John.
Didn't they find that the beams that were to run the length of the ship only went halfway and were joined amidships? allowing the ship to bend in the middle.

All ships bend and large bulk carriers are always hogged or sagged. Around the 30's and 40's, Greek and other ship owners were known to permanently hog vessels with the view of putting the Plimsol line higher so they could load more cargo. We carried out an experiment at DBCT loading large coal carriers using a laser beam down the deck and measuring the deflections of the deck, the results were quite frightening, showing that the length of the ship showed a series of waves up and down. some quite large.
I think it was a series of P & O bulker's which were fitted with recording strain gauges amidships as an experiment by some expert body. Don't know of the results.
When only part loading coal ships it was quite common to have them shift between berths and ports with over a metre hog or sag.

[John Arton]

Believe there was always questions regarding the junction between the longitudinal framing of the cargo hull part and the transverse framing aft for the engine room.
In 69 the Beaverfir was fitted with strain guages consisting of metal strips fitted to the deck that weren't connected to mechanical counters in a unit housed in the she wheelhouse. We would record manually the counter readings and send off the sheets to the British ship research society who had fitted the gear. They were on board after finishing the installation and on shifting berth in the Vic. docks, were horrified at how the readings altered, saying that we must be daft to actually go to sea on the ship.

John, you are correct in my mind.
My close friend, a master mariner but died about 20 years ago, was on a sister ship of the Derbyshire and he recounted to me long before any more recent evidence, that they were forever welding up cracks in that area and inspecting for cracks on a very regular basis.
I can tell you his name and some background as I believe you may be about the same era as him and he did his tickets at SSMTC
