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

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

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
