How to decarbonize your ship - general cargo ship with battery hybrid

This case study examines a general cargo ship with an auxiliary engine of 116 kW that is outfitted with a battery to make it a ‘battery hybrid’ while at berth. The battery pack powers the ship for several hours while idling or moored and is recharged using the auxiliary engines. Cost savings generally occur with an average engine load below 50%, but are mostly dependent on engine maintenance costs, spares and consumables as well as total battery pack costs.

How to decarbonize your ship - Inland Waterways + Shore Battery

This is a case study on the ‘Skoon Skipper’, a general cargo large Rhine vessel, with an average of 40 [kW] power demand while moored to which a shore battery is applied. Batteries can help you comply with shore power regulations where no infrastructure exists with limited to no CAPEX investments. CAPEX is €0 for this case study as the battery pack is rented at an estimated €400 dayrate. Purchase cost for battery pack are approx. €350.000. This case study is powered by our preferred partner Skoon.

How to decarbonize your ship - Large Fishing Trawler

This is a case study on how to decarbonize a fishing trawler - the Jacobus Maria - using shore power, battery hybrid EES and biofuels. 20% CO2 reduction is achieved, half of which stems from the use of biofuels (HVO). The hybrid battery pack is economically not feasible with the assumptions used and the operational profile. The Jacobus Maria has 1 MW installed engine capacity. Total cost would be at least €1M. 10% CO2 reduction can be achieved with approx. €50k.

How to decarbonize your ship - RoRo Passenger with hull coating

This is a case study on how to decarbonize a ro-ro passenger vessel by applying Ecospeed to its hull. Ecospeed is a hard, non-toxic coating which provides long-lasting protection for all ship hulls. The hypothetic vessel is called ‘Lady Ice Cold’, a ro-ro operating in North-Western Europe with 33 MW installed engine capacity. Ecospeed reduces carbon emissions by 9% - 16% with a total CAPEX of €390.000.

How to decarbonize your ship - Full Electric Tugboat

This is a case study on how to decarbonize a tug by making it full electric. It is an homage to Damen’s electric tug ‘Sparky’. In practice, fully electrifying a vessel means to install a - very large - battery pack, in this case at least 3 MWh. This would also be the largest cost component, outweighing switchboard modifications, inverter and other electrical equipment. Cost reductions in OPEX/dayrate are high, between 50% to 90% in extreme cases.

How to decarbonize your ship - Inland Waterways + Solar PV

This is a case study on how to decarbonize an inland waterway ship with solar PV technology. Flexible solar PV panels from Wattlab are placed on an inland ship’s hatches in order to reduce fuel consumption while idling or moored. In some cases, the auxiliary generators can be switched off, resulting in an expected CO2 reduction of 26% - 100%.

How to use the Decarbonize tool for your ship

After selecting your ship type and pressing start, you can check your ship details and customize your operational profile. Choose the amount of sailing days, increase or decrease power demand, change your specific fuel curve and more!
How much do you need to decarbonize? To which rules and regulations do you need to comply? Check out what you need to do and set your ambitious (or not so ambitious) targets here - we don’t judge!
Decarbonize! Choose up to three preferred carbon reduction measures: a shore power measure, a measure that prevents the combustion of fuel, and a measure to change your fuel. Compare different technologies and play around with the fuel costs to see how they impact your dayrate!
Customize your business case and determine how other ways of financing, different assumptions or the fuel price benefit your investment. This section is specially designed for the CFOs among us!
Input your email and receive a Price Indication PDF with a comprehensive overview for your vessel. The report includes a detailed cost breakdown for your technology and more background information on your preferred decarbonization measures. Contact the helpdesk at any time for support!
