Manufacturing accuracy

Class II, Class I and Class S.

Every propeller and blade leaving Fundilusa is manufactured and verified to an ISO 484 accuracy class agreed with the customer, and checked against it before the classification society signs it off. The class sets the permitted deviation on pitch, blade thickness, section geometry and blade-edge form.

ISO 484 · Medium accuracy

Class II

The working standard for general merchant tonnage, where the duty is steady and the priority is robustness and cost per delivered ton.

  • Bulk carriers
  • Tankers
  • Feeders
  • Tugs
ISO 484 · High accuracy

Class I

Tighter tolerances on pitch and section geometry, specified where fuel efficiency and vibration behaviour are contractual and the propeller has to hit its design point.

  • Container ships
  • Ferries
  • Offshore
  • Ro-Ro
Highest grade
ISO 484 · Very high accuracy

Class S

The tightest tolerance band in the standard. Specified when noise, vibration and cavitation have to be held to a minimum, and when the blade has to survive loads far beyond open-water service.

  • Naval & military
  • Icebreakers
  • Research
  • Cruise

Class S in practice

Where the tolerance band gets narrow.

Class S is not a different alloy: it is a far narrower tolerance on the same casting, held through pattern making, casting simulation, CNC machining, hand finishing and dynamic balancing. Getting there consistently is a question of process control, not of a single machine.

It is the class Fundilusa supplies for the work where a propeller cannot be average: naval and military programmes, where radiated noise is a design requirement in itself, and icebreakers and ice-class tonnage, where the blade has to take impact loading that no open-water propeller ever sees.
