Steering module
The steering module is outfitted in advance
Structure to weld the block to hull
The slewing part for attaching the propulsion module
Slewing bearing
Seals and greasing lines
Steering gear rim
Steering gear motor/gear turrets
Factory acceptance tests are performed before delivery
The slewing bearing oil space is filled before delivery to
avoid corrosion

Welding the steering module
Practical at the point at which the ship’s hull is ready to
receive the forces from the steering module
Bottom of the hull ready
Upper deck ready, or supports installed underneath
Strain of hull to be avoided afterwards
Shipyard’s Chief Welder is expected to lead the work
Welding according to shipyard’s standards and
following ABB’s instructions
ABB supervisor inspects all phases of work
Most important is to keep the steering module shape round
Welding order is crucial, regular measurements

Installation of the propulsion module
After the steering module is welded
Lifting of the propulsion module according to ABB
instructions
Different possibilities for lifting

Transport wagon
Hull block wagon
Shipyard performs under ABB supervision
Installation made according to ABB instructions

Piping and flushing of oil lines
Must be done before connection to the systems
Executed according to ABB Azipod pipe treatment and flushing instructions
Cleanliness is crucial to ensure operation of the system
Turbulent flush to be achieved in piping
Requires an adequate flushing unit on the shipyard
Oil samples taken to prove acceptable results
Surrounding and connection ambient cleanliness is essential
