Regulation expertise
General Overview
It’s time to respond to ever-tightening regulations. The International Maritime Organisation’s immediate reduction targets as well as longer-term global zero carbon shipping goals demand that shipowners promptly invest in green shipping technology. Norsepower can help with this.
Our product is available today – and delivers third-party verified results: 5–25% of fuel savings and emission reductions, and even more in good conditions. The fuel savings are translated directly to emission reductions – and the current and upcoming regulation loves emission reductions. The upside consists of fuel savings as well as savings in regulation-related costs, but also direct regulatory rewards. We are here to help!
CII
The Carbon Intensity Indicator (CII) is a ship rating system by IMO (International Maritime Organization. The CII rating determines the required annual emission reductions on a scale of A, B, C, D or E – a bit like power consumption in household devices. A ship rated D or E for three consecutive years will need to submit a corrective action plan to climb back to C or above. If this sounded a bit complicated, don’t worry – here is a nice image from DNV that might help:
Norsepower Rotor Sail™ helps to reduce ship’s fuel consumption and CO2-emissions and therefore improves its CII rating. Additional CII benefit can be achieved with voyage optimization by further cutting the fuel consumption, but also on the same time increasing the distance travelled by the vessel.
Norsepower is an expert in this regulation and has, in its part, participated in drafting it. With Norsepower Rotor Sails™ and our deep domain knowledge we will optimize your fleet to be future-proof and maximize your advantage against your competition. Let’s start today!
EEDI – for newbuilds
The EEDI (Energy Efficiency Design Index) an IMO regulation and is used to calculate a vessel’s energy efficiency. The EEDI Index calculation is based on emissions, capacity, and speed into account.
Norsepower Rotor Sail֭™ is considered an innovative propulsion technology in EEDI regulation. There are specific guidelines on how to calculate the EEDI-benefit of wind propulsion systems in MEPC.1/Circ.896. Norsepower has developed a method, “E-cal”, that complies with the regulations and has been validated by DNV. Norsepower Rotor Sail™ is very cost effective and powerful way to reduce ships EEDI.
The mathematical formula is quite complex:
But we have good news for you: Norsepower is an EEDI expert. As the pioneer of the in-dustry, we have been present when the legislation was drafted – and we even have a DNV-approved E-Cal method; a way to make wind propulsion related EEDI calculations simple and accurate. In practice this means that you will save time and optimize your investments to your fleet.
FuelEU Maritime
FuelEU regulation by European Commission came into effect in 2025. It sets maximum limits for the yearly average greenhouse gas (GHG) intensity of the energy used by ships above 5,000 gross tonnage calling at European ports, regardless of their flag. The targets cover not only CO2 but also methane and nitrous oxide emissions.
The use of wind propulsion is rewarded in FuelEU regulation. Reducing GHG-intensity of the fuel enables the ships with Norsepower Rotor sail™ to comply with the regulation. This is done without using expensive fuels. Even pooling option for the additional compliance with other, non rotor sail vessels of the fleet, exists.
In practice the FuelEU defines, what kind of fuel you can use – and Norsepower can help you to optimize the situation, as your product is calculated in to the formulas.
It is worth noting that the GSF (Global Fuel Standard) will be an enhanced, global version of FuelEU regulation. We are currently in talks with IMO to make sure that this legislation will reward for concrete, measurable emissions reductions – not just having something untested that happens to look like a sail on your deck. Be it EEDI or GSF, just contact us when you need simple, proven solutions.
EU ETS
Large ships (over 5000 gross tonnage) entering EU ports are included in the EU’s Emissions Trading System (EU ETS) . In practice, this means that the more the ships produce GHG emissions, the more they need to buy expensive emission allowances.
Norsepower Rotor Sails™ reduces ships emissions which means that less of our cusomers’ money needs to be spent on allowances.
The system covers 50% of emissions from voyages starting or ending outside the EU – and 100% of emissions between EU ports. The EU ETS applies to CO2 emissions, with CH4 (methane) and N2O (nitrous oxide) emissions included starting from 2026. Here’s a nice timeline image from DNV:
Shipping companies are required to surrender allowances for a portion of their emissions during an initial phase-in period. For 2025, 40% of their emissions reported in 2024; for 2026, 70% of their emissions reported in 2025 – and from 2027 onwards, 100% of their reported emissions. But you don’t have to worry; Norsepower, as the foremost EU ETS wind propulsion expert in the world, will help you throughout this journey.
