ship energy efficiency fuel economy


Our Fleet Performance Department works hard to ensure that vessels under OSM management are energy efficient. Your ships need energy efficiency for four reasons:

☑️ SHIP FUEL CONSUMPTION REPORTING: We help you save fuel; you save money.
☑️ IMPROVED SHIP PERFORMANCE: We optimize the speed and effectiveness of your vessel, you save time at the sea and money.
☑️ EU MRV and IMO DCS: Our solutions are fully compliant with MRV and DCS reporting.
☑️ ENVIRONMENT: Our data helps you to create environmental and sustainability reports, so you have a full overview of your environmental adequacy, both for your own records and towards your customers.

We have the tools and competence to monitor and improve fuel consumption on ships managed by OSM. Our in-house data collection system (VRS) is tailor-made to collect all necessary data to track the environmental footprint of your ship, improve ineffectiveness, and give you necessary voyage and vessel information. Additionally, we ensure that vessels operated under OSM management are contributing to the overall goal of reducing the GHG emissions from ships.

OSM maintains an advanced data collection system (VRS) which enables us to provide you with an in-house online daily reporting system on your ship’s energy efficiency.


OSM maintains an advanced data collection system (VRS) which enables us to provide you with an in-house online daily reporting system on your ship’s energy efficiency. Our system collects data from your vessels such as the speed, distance, consumption, garbage, cargo, port calls etc. and reports to you on how to save energy. VRS provides dashboards and analysis reports.

VRS presents a clear picture of ship fuel consumption reporting by giving owners, operators and captains the total fuel utilization overview in the fleet, as well as insights into root causes on individual vessels through a highly user-friendly interface.

All the data we collect from your vessel is utilized for ship performance optimization


All the data we collect from your vessel is utilized for ship performance optimization such as:

Hull performance optimization

One of the most important factors for your ship is to be energy efficient. Increased hull friction from fouling, can give you a large loss in terms of increased fuel consumption. We monitor and assist your vessels to improve hull performance and monitor how the vessel is operated. We have strong competence in everything from choice of anti-fouling, hull cleaning technologies, and fouling risk in different conditions and areas.

Speed and consumption tables and calculator

Our expertise is also utilized to give you strong estimates on the expected consumption of your vessel on your next voyage, which is valuable for voyage planning and budget.

Daily monitoring of auxiliary and boiler fuel consumption reports

The system provides daily monitoring reports on fuel expenditure, and we assist you to reduce it.

IMO (The International Maritime Organization is a specialized agency of the United Nations which is responsible for actions to be taken to increase safety and security of international shipping and to prevent pollution caused by vessels) launched the Energy Efficiency Design Index (EEDI). The EEDI is a one-time ship performance calculation, done by class on sea trial at the delivery of a new build. All the new ships (within the requirements) in OSM have this in their EEDI Technical file and they are EEDI compliant.

IMO will also launch an Energy Efficiency Existing Ship Index (EEXI) which is an “EEDI” for existing ships. It is similar to the EEDI, but it also applies to the older ships as well. EEXI will enter into force the 01.01.2023.

The Ship Energy Efficiency Management Plan (SEEMP) is a document that should be on board on all vessels. This document is an energy efficiency management plan with measures and guidance to running ships to be energy efficient. All ships under OSM Energy Efficiency Management possess the Ship Energy Efficiency Management Plan.

The EEOI is the total carbon emissions in a given time period per unit of revenue tonne-miles. EEOI is a calculation per voyage, saying something about the different voyages transport efficiency (including speed and cargo utilization). Now IMO has launched the new operational Carbon Intensity indicator (CII) which will enter into force first 01.01.2023, which is calculating the carbon intensity per DWT mile. Vessels will based on this, receive an annual rating, A-E, Where C or better is compliant. Three consecutive years with D-rating or one year with E will require measures to improve ship performance.

In addition, there will be updated requirements related to the Ship Energy Efficiency Management Plan (SEEMP) – “Enhanced SEEMP”. The updated SEEMP Guidelines are still not published from IMO but are expected before CII and EEXI enter into force. The Enhanced SEEMP will contain annual updates on CII-rating and measures in case of non-compliance.
