19/49

Why are the anchors lost?

Vessel anchoring too deepFrom the rules we see that by

anchoring much deeper than 100 m it is a great risk that thewindlass will not be able to retrieve the chain and anchor

Vessel anchoring in very rough weather conditionsThe

windlass is designed for operating at a speed of about 9 m/min

which corresponds to 0,15 m/s. With heavy swells or waves the

vessel can be subjected to accelerations above 1 m/s. If the anchor

is still stuck to the bottom the windlass motor will be overloaded andcrushed

Vessel is drifting during anchoring operationsIf the vessel is

moving with a speed over ground greater than 9 m/min or 0,3 knots

while the anchor is still stuck to bottom the windlass motor will be

overloaded and crushed

June 2015 19


20/49

Windlass design criteria

The class rules are based on anchoring in sheltered areas protected from the open

Basic design criteria

Nominal anchoring depth 82,5 m

Wind 25 m/s (~50 knots)

Current 2,5 m/s (~5 knots)

Waves and swell are not

considered!

IS THIS REAL LIFE?

This is what your windlass is designed for!

21/49

design criteria (cont.)

Windlass nominal lifting force based on Grade 3 anchor chain is given through the

F = 47,5 x dc2 [N](dc = chain diameter in mm)

Nominal lifting force is sufficient to lift a free hanging anchor from a depth of 82,5 m

Mean speed between 82,5 m and 27,5 m shall be 9 m/min (0,3 knots)

The winch motor should be able to operate at nominal lifting force continuously for minutes

In order to break out the anchor the maximum lifting force shall be 150% of nomina

The winch motor should be able to hold this load for minimum 2 minutes.

reduce number of lost anchor incidents

BUT

A better understanding of current design limitations, maintenance issues and opera

reduce number of lost anchor incidents as this will:

prevent anchoring at too deep water depths or poor anchoring grounds

make sure the vessel has no speed over ground during the anchoring operation get the master to decide to leave the anchoring place before the weather gets to

make sure that the windlass brakes are correctly adjusted

make sure that the windlass bearings and gears are properly lubricated

Safe Chain Stopper (SCS)PATENTED

To increase the safety for vessels when heaving anchor,

Pusnes has developed a new chain stopper which ispatented. safe chain stop

This stopper will arrest the chain if the windlass starts to

render, i.e. when the pulling force in chain is bigger than

the pulling force of

the windlass.

Designed for chain diameters from 60 mm and upwards.
