Wärtsilä Shaft Power Limitation

Preparing for Energy Efficiency Existing Vessels Index

By December 2023 all existing merchant, cruise and ferry vessels, above 400 GT* and which engage in international trade, must comply with the requirements of the IMO’s Energy Efficiency Existing Ship Index (EEXI), which defines a minimum energy efficiency level for vessels.
*falling under MARPOL Annex VI

Wärtsilä Shaft Power Limitation is an upgrade package for vessels with Wärtsilä controllable pitch propellers that will enable compliance with the new requirements. The fully integrated solution can be installed as an add-on to Wärtsilä systems and has been designed in collaboration with some of the major classification societies.

Key benefits

  • Ensure compliance with EEXI requirements
  • A standardized and cost-effective solution
  • Integrate with existing Wärtsilä propulsion controls system
  • Does not limit operational flexibility for ships with multiple shaft lines or multiple engines per shaft, or those with PTO and/or PTI systems
