Decarbonization

Sep 1

Explore decarbonization pathways for your ship by comparing technologies, CAPEX, OPEX and more

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!

First Aid for a Sustainable 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.

First Aid for a Sustainable Ship - Hopper Dredger + Methanol

This is a case study of a trailing hopper suction dredger with 14MW installed power - the ‘Happy Hopper’ - which is converted to methanol combustion. This case study is inspired by the amazing work done by Van Oord. With the given assumptions on emission factors for methanol, 93% CO2 reduction is achieved. CAPEX for a methanol refit of this size is approximately €6M+, of which roughly €5M is intended for engine refit only. OPEX will be greatly increased unless methanol price is below €500 per mT.

First Aid for a Sustainable 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.

First Aid for a Sustainable Ship - Ro-Ro Passenger

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.

First Aid for a Sustainable 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.

First Aid for a Sustainable 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%.

Making the Impossible Possible

This blog sketches a vision on how to convert the largest crane vessel in the world - Sleipnir - owned by Heerema Marine Contractors, to a zero-emission vessel. Several promising carbon reduction measures are combined which are technically viable and based on matured technology including electrification and BES, solar panels, synthetic fuels, CCS and possibly hydrogen combustion.

Overview of Shore Power Sockets and Plugs - IEC/IEEE 80005

IEC/IEEE 80005 is the main standard for shore power. This standard categorically divides shore power plugs and sockets into low voltage shore connection systems (LVSC < 1 MVA) and high voltage shore connection systems (HVSC > 1 MVA). LVSC systems are governed by IEC/IEEE 80005-3 for operability and IEC 60309-5 for dimensions. HVSC systems are governed by IEC/IEEE 80005-1 for operability and IEC 62613-2 for dimensions.

The State of Methanol as Marine Fuel 2023

This blog is a state of the use of methanol as marine fuel as “quick” reference for shipowners. Key points include costs for retrofitting the ship and engine, range between € 250-€650 per kW, elaboration on IGF code for low flashpoint fuels and technical considerations for conversion and working with methanol. Availability for methanol is good, but bunkering for large vessels mostly non-existent. Methanol price per kilogram is historically lower than regular MGO.

Marine Exhaust Gas Heat Recovery Systems

Marine exhaust gas heat recovery systems can be a useful measure to reduce fuel consumption by 5% for typical cases, with up to 15% for favourable engine and ship characteristics. As a rule of thumb, heat exchangers become more efficient and cost-effective the larger your engine becomes. Conversion of heat to electricity is recommended for diesel-electric vessels, as well as the use of engine cooling water instead of exhaust gas heat.

Overview of Ports’ Sustainable & Shore Power Ambitions

Most ports have the ambition to become carbon neutral by 2050. This typically excludes vessel emissions and focusses on Scope 1/2 port operations only. A significant portion of ports around the world have signed shore power declarations to ‘deploy shore-side electricity by 2028 where possible’, including all large North Sea ports, Los Angeles, Montreal and all large Japanese ports. Cruise and container vessels are the primary target for most ports’ regulations and EU will start taxing vessels via EU ETS from next year onwards.

Specific Fuel Consumption [g/kWh] for Marine Engines

Specific Fuel Consumption (SFC) of marine engines ranges between 155 and 200 g/kWh on optimal load settings, mostly dependent on engine speed (low, medium, high). Specific fuel consumption increases dramatically for approach at low power (30% Pmax) and especially at idle (7% Pmax).

What is the carbon footprint of steel?

Weighted average carbon footprint of steel is 1.85* tons CO2 to 1 tonne steel produced according to Mckinsey and the World Steel Association.
