EPL installation for EEXI compliance in shipping
The Energy Efficiency Existing Ship Index (EEXI) requires shipowners to improve the energy efficiency of their vessels. A commonly used solution to comply with this regulation is the implementation of an Engine Power Limitation (EPL) or Shaft Power Limitation (ShaPoLi) system.
Normec Verifavia supports shipowners with EPL and ShaPoLi supply and installation, ensuring your vessel complies with the EEXI requirements without unnecessary operational impact. Thanks to our technical expertise and international partner networks, we guide the entire process: from system selection to implementation.
Mechanical EPL
A mechanical Engine Power Limitation is a simple and cost-efficient solution.
Characteristics:
- Relatively low costs and quick installation
- Direct mechanical limitation of engine power
- Simple technology without complex electronics
Limitations:
- Adjustments to power require manual intervention
- Less flexible for future adjustments
- Changes may require additional technical modifications
ShaPoLi system
A Shaft Power Limitation (ShaPoLi) system offers a more advanced and flexible solution.
Characteristics:
- Electronic control of shaft power
- Possibility of temporary overrides in emergency situations
- Adjustable settings via software
- Integration with digital monitoring and performance platforms
Limitations:
- Higher investment costs
- Longer installation time than mechanical EPL systems
Our approach
Choosing and implementing the right system requires a good balance between technical feasibility, costs and operational performance.
Normec Verifavia supports you with:
- Selection of the most suitable EPL or ShaPoLi system
- Procurement and planning through reliable international partners
- Installation according to manufacturer specifications and industry standards

Frequently asked questions
-
EPL limits motor power mechanically, while ShaPoLi controls shaft power electronically. ShaPoLi generally offers more flexibility and digital integration capabilities.
-
Not always. EPL is a commonly used solution, but depending on the vessel, other technical measures or efficiency improvements may also be used.
-
Installation time depends on the type of system and vessel. Mechanical EPL systems can often be installed faster than ShaPoLi systems.
-
Yes. ShaPoLi systems can often be connected to performance monitoring and digitization tools to improve operational efficiency.
-
Yes. We offer support throughout the life cycle of the system, including training, operational guidance and technical support.
-
The choice depends on several factors such as timeline, budget, long-term strategy and the operational profile of the vessel. A Mechanical EPL is often the best choice when quick implementation and cost efficiency are important.
A ShaPoLi system offers more long-term flexibility, with advantages such as adjustable settings, improved efficiency and possibilities for digitalization and integration with monitoring tools.
-
Installation time varies by system type:
Mechanical EPL: usually about 2 to 3 weeks
ShaPoLi: usually 5 to 8 weeks, as it is an electronic system with additional cabling and integration.
The exact schedule depends on the vessel type and technical configuration.
-
Yes. Normec Verifavia provides extensive training for the crew, tailored to the specific EPL or ShaPoLi system installed onboard. The training includes, among other things:
Safe operation of the system
Emergency procedures
Correct documentation and recording of usage
This ensures the crew can operate the system safely and efficiently.
-
Both systems primarily require routine maintenance according to the manufacturer's guidelines. This maintenance can usually be performed by the ship's crew.
For ShaPoLi systems, periodic maintenance or component replacement may be required after several years. The exact requirements vary from system to system and always follow the manufacturer's recommendations.
-
Normec Verifavia offers two services that both relate to Overridable Power Limitation (OPL) systems such as EPL and ShaPoLi, but with different objectives.
OPL Supply & Installation Service
This service focuses on the technical implementation of the system onboard. This includes:
Selection of the correct EPL or ShaPoLi system
Procurement and supply through reliable partners
Installation and testing onboard
Crew training
Guidance throughout the entire implementation process
The objective is to make vessels technically compliant with EEXI regulations.
Onboard Management Manual (OMM) for OPL
This service focuses on operational and regulatory documentation for vessels where an EPL or ShaPoLi system has already been installed by another party.
It includes, among other things:
A verifiable compliance framework for the use of the system
Procedures for activation, deactivation and emergency situations
Guidelines for recording, reporting and operational management
Full alignment with IMO Resolution MEPC.335(76)
This ensures that the system is not only technically installed but also used correctly and in accordance with international regulations.
