• Pod rotation speed• DP – Dynamic positioning• Pod RPM Blanking at various angles• Pod seal and bearing problems

AZIPILOT Workshop WP 4Earlier Gareth said –

“When conducting a series of crash stops from an initial speed of 13½ knots trials showed the quickest way to stop the vessel is by turning the pods through 180º inboard maintaining full positive rpm.”Which way is inboard? Is the propeller pulling or pushing?

Where is he squirting the water?

• Many pods pull

• But some push and others do both at the same time!

Let’s look at some specific questions……

So, how do we train Ships Masters?

…….and also how do we train the Pilots?

AZIPILOT

AZIPILOT Workshop WP 4

How can we get the industry to standardise terminology for all ACD vessels?

AZIPILOT

AZIPILOT Workshop WP 4

Do we need controls with feedback, if we attempt something (operationally) undesirable?

AZIPILOT

AZIPILOT Workshop WP 4

Are verbal commands for pods (especially multi-pods) just too complicated?

AZIPILOT

AZIPILOT Workshop WP 4

Do ACD vessels require specialist 'certificated' training, as for DP (Dynamic positioning)?

Or only for multi podded vessels?

AZIPILOT Workshop WP 4

How can a Pilot know that a Master is 'competent' in handling a ACD vessel?

How can a Master know that a Pilot is 'competent' in handling a ACD vessel?

AZIPILOT

AZIPILOT Workshop WP 4

On the face of it, ACD vessels should be easier to handle than a conventional vessel, but are they?

AZIPILOT

AZIPILOT Workshop WP 4

For a traditional seafarer, are ACD vessels intuitive to handle?

AZIPILOT

AZIPILOT Workshop WP 4

How do port authority's 'control' the movement of ACD vessels in extreme weather events?

AZIPILOT

AZIPILOT Workshop WP 4

Should each ACD vessel develop and promulgate a 'safe operating envelope'?

If so, what criteria would determine a 'safe operating envelope'?
