Inventions and devices

In our previous posts we uncovered a number of inadequacies in the expert analysis carried out during the 2004 Gaul RFI.

More recently, we have highlighted some serious flaws in the RFI analysis pertaining to the Gaul’s sinking scenario.
Yesterday, we raised doubts as to the quality of the information put forward by the RFI panel of experts in their paper: ‘The Loss of the M.F.V Gaul’ which was presented to the Royal Institution of Naval Architects in 2006.

Today, we would like to go back to that same paper and question why a door self-closing mechanism, similar to the one pictured below, was mentioned only in that document, while the 2004 RFI report, the transcripts of evidence or other related sources do not seem to include any reference to such a device.

“8.3(c) Flooding of liver plant

Subsequent to the model testing, it was found although the door from the factory to the liver plant room……………. The door was partially shut by a self-closing device…”

The answer may be quite simple: without such a device, which would have allowed floodwater to become trapped inside the liver plant room (and thus change the stability behaviour of the vessel), the vessel-sinking scenario chosen by the RFI experts would have been less plausible.

Apart from the lack of evidence as to the existence of a self-closer, it is also important to note that the door to the liver plant room on the factory deck was a weathertight door to which - naval architects know it is neither standard shipbuilding practice nor stated norm - self-closing devices are not fitted because they do not work correctly.
