"SEPIA"' was alike
Two S-class sisters "SEPIA" PHKW, and "SERENIA" GHLE were also taking part in this experiment.
Did have the same equipment.
So did the "ALUCO" GCJU, "ARIANTA" GCNU, and "AMORIA" GCXU
The program was intended to detect changes in the performance of ships at sea almost immediately in London.
Even though a vessel is on the other side of the world.
The cause of these changes should be isolated.
A system of high-speed transmitting and analysing of information was developed by Shell International Marine Ltd and MIMC.
New instruments for recording vital data on board ships and new wireless transmission equipment was installed.
An air-conditioned crew cabin aft housed a specially built data logger.
Its clock speed was about one cycle per second.
Output was in the form a 5 unit telex code punched paper-tape.
Ships performance data was transmitted daily into Shell Centre London.
This data is fed into computers.
The system should assist Shell in improving the efficiency of its oil tanker operations.
A ship's performance changes as a result of deterioration of the boilers, marine growth and corrosion on the hull or damage to propellers.
The only means of measuring the ship's performance until now (1964) is the "measured mile".
For large tankers there were only two places suitable for making the measured mile runs,
one off Scotland and the other off the coast of Malta.
The whole aim of Shell's approach to the transmission and analysis of voyage data has been precision and speed.
To obtain reliable data great attention has been paid to the installation of the most accurate and reliable instruments possible.
For example, Shell's research laboratories have modified the design of a torsion meter so that its measurements can be fed directly to automatic data recording equipment (data logger) on board.
The data are transmitted to the GPO radio station at Bearley, Warwickshire or to the Dutch PTT station Scheveningenradio.
The signals are then sent on by land line to Shell Centre in London.
An exceptionally high degree of transmission accuracy is absolutely essential in such a system, which must operate over great distances under adverse conditions of interference, noise or fading.
A new type of automatic error-correcting equipment was developed by MIMC, "Autospec" .
This system requires no extra transmission path for requesting repetitions, as compared to the Dutch SITOR.
Teleprinter signals are changed into a special code and fed into the ships radio transmitter.
At the receiving end, Shell Centre London, the Autospec terminal can determine whether an error has occurred and, in the majority of cases, automatically correct the error.
