Sea trialling
Before commencing system setup, make sure that:

The vessel is securely moored (jet commissioning may produce large thrust forces)

All controls are set to zero speed (transfer enable icon will display on the station
control panel).

Gearboxes (if installed) are in neutral.

No fault alarms are active (fix any alarms before continuing).
After the vessel has been launched, but while it is still moored, check the following:
Control checks

Set the dual lever module to full ahead. Check that the throttles give full on with 100% throttle demand.

Check the throttle range while in backup.

Check that the engine start interlocks operate when a control input device is not at the zero speed
position.

Check that the gearbox drive and backflush relays operate when activated (if a gearbox is installed).
Engine checks
For each engine:

Start engine.

Make sure the engine idle speed is acceptable.

Make sure the gearbox activates when pressing the gearbox button.

Check the JHPU oil level every few minutes during initial operation.

Visually check for any oil leaks.
