WÄRTSILÄ OFFERS EEXI COMPLIANCE THROUGH POWER LIMITATION

Friday, November 26, 2021 

Wärtsilä has launched a new series of power limitation solutions that enable compliance with the IMO’s Energy Efficiency Existing Ship Index (EEXI) regulation, which the company believes completes its range of solutions for IMO environmental regulatory compliance, covering both newbuild and retrofit projects.

The EEXI regulation comes into effect in 2023 and stipulates the minimum energy efficiency level for existing ships already in service. Wärtsilä’s new power limitation systems allow owners to meet this requirement, despite the tight implementation schedule. Wärtsilä’s environmental offering includes various energy efficiency solutions that enable compliance with the IMO’s Carbon Intensity Indicator (CII) requirements, which form part of the IMO’s strategy for reducing greenhouse gas emissions from shipping.

For meeting the EEXI requirements, three macro areas are relevant, namely Power Limitation, Energy Efficiency technologies, and Fuel upgrades. With the introduction of these latest power limitation solutions, Wärtsilä covers all three areas with proven solutions, and can thus recommend the optimal choice for meeting the specific needs of owners and operators.

Giulio Tirelli, Director Business Development, Wärtsilä, said: “With this latest launch, Wärtsilä once again emphasises its commitment to supporting customers in their decarbonisation efforts in line with the global targets set by the IMO. We can offer a complete set of opportunities for complying with the existing and upcoming regulations.”

The power limitation upgrades being launched by Wärtsilä are verified and approved systems. They comprise Engine Power Limitation for four-stroke engines, Engine Power Limitation for two-stroke engines, Shaft Power Limitation for vessels with a CP propeller and a Wärtsilä Propulsion Control System, and Power Limitation specifically dedicated to diesel-electric installations.

The upgrades effectively limit the engine or shaft power during normal operation, regardless of the power train combination and control system arrangements. The set limits of the solutions can all be overridden from the bridge. This is a mandatory feature stipulated by the IMO / MEPC guidelines, as are the monitoring and recording functions. The system data is stored in accordance with the regulations for inspection purposes.
