Reliability Case Notes No. 5: Report on water leak in Autosub6000 charge blanking plug. Burton blank No 82530-12-5502-3212-0000 NR. Southampton, UK, National Oceanography Centre Southampton, 7pp.
(National Oceanography Centre Southampton Research and Consultancy Report, 66).
The blanking plug, Burton Part No 82530-12-5502-3212-0000 NR, which blocks off the charge lead on Autoub6000 leaked water during two missions on the JC027 cruise. An investigation showed fibres had become trapped inside the connector which would have caused a leak. Measurement of the plug and connector shows the secondary seal around the pins and sockets to be marginal. Care to avoid debris being trapped and better tools to aid tightening the connector will avoid a repeat of the problem.
