ABB Azipod® OY, FinlandCruise
liner with two MW Azipod® units.
Azipod® is a podded propulsion drive, azimuthing through 360°. The
AC motor drives a fixed-pitch propeller directly.
Ship propeller brakes:
One pneumatic brake BSAA 100-P-100 is used for each Azipod®
unit.
When the ship propeller is to be stopped due to repair of the
electrical AC motor inside the pod, the brake needs to be
activated.
Steering brake:
The steering system consists of two hydraulic motors, which
activate a steel evolvent tiller ring.
One pneumatic brake BSAA 100-P-100 is used for holding the steering
unit. |
Stolt-Nielsen Inc. USA
Svendborg Brakes was selected when Stolt-Nielsen ordered
propeller shaft brakes.
Several diesel/electrical powered ships have been fitted with the
Monospring version of our BSAH 300 brake with a hydraulic
unit.
The solution stops the propeller shaft turning when the ship engine
is stopped but the ship is still moving.
There are 2 brakes and a hydraulic unit used for this project
fitted to a total of 8 ships.
Svendborg Brakes also produced the discs and modified the mounting
hubs to suit. |
Roxboro, South Carolina,USA

approx. 35,000 N. The brake is used as a steering brake on the
Azipod, with more than 50 brakes delivered for similar projects
since year 2000. |
