Scope of service

Alfa Laval takes responsibility for the entire Alfa Laval Touch Control retrofit process. This includes:

  • Overview of existing setup 
    Either through pre-inspection or with the assistance of the vessel’s crew, our experts assess the current setup (with or without MGO conversions) to eliminate risks and ensure success.
  • Engineering and reclassification
    Based on the pre-inspection and/or information provided by the vessel’s crew, our experts undertake the necessary engineering work. We also manage the reclassification of your vessel or vessel series with the upgraded control system.
  • Hardware exchange
