Shotover Jet mechanical staff carry out checks daily.
The mechanics themselves get assessed throughout the year by either our Maintenance Manager or Workshop Supervisor who audit their checks to ensure compliance.
Our jet boats are audited annually by two independant parties - an internal expert whom has over 10 years' experience and an external Maritime New Zealand authorised specialist.
Every year we put together a comprehensive jet boat refit programme which predetermines when jet boat engines and jet units will be rebuilt. At regular intervals, we strip, fully check and refit all of our jet boats.
We have introduced a computerised critical parts tracking system which ensures the integrity and safety of critical componentry in our jet boats. Every critical part of the jet boat that could cause failure of a vital function is tracked so we know how and when it is serviced and/or replaced. For example, in addition to daily visual inspections, the tracking system requires crack testing on steering nozzles every 500 hours and that, irrespective of whether there is any damage, the steering nozzle is replaced every 2,000 hours. The system is computerised, and ensures that no critical component is overlooked during the maintenance programme.
In October 2001 we introduced Reliability Centred Maintenance (RCM). This is a maintenance methodology used in the airline industry to improve engine efficiency and reliability. RCM allows Shotover Jet to raise the standard for the jet boating industry and assist in the maturing and development of our maintenance processes. The initial training of our mechanical staff started in October 2001 and was carried out by Price Waterhouse, the official licensees for RCM.
