How to decarbonize your ship - RoRo Cargo + shore power + FuelEU
This case study determines the impact of FuelEU Maritime on a shore power refit for a RoRo Cargo ship under multiple loading and operational conditions. Pending on the amount of days connected to the grid and the average load while moored, it is estimated that shore power can save €250,000 per year.
How to decarbonize your ship - battery hybrid + varying engine load
This case study also 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. Again the battery pack powers the ship for several hours while idling or moored and is recharged using the auxiliary engines. This time however, engine load is varied in different loading scenarios to determine the impact of different operational profiles on the business case.
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.
Impact of FuelEU Maritime on shore power business case
This is a case study that determines the impact of FuelEU Maritime on a shore power refit business case up to 2050, taking several ships and varying input parameters to determine the impact under multiple conditions. As FuelEU Maritime will make shore power mandatory in 2030 for passenger- and containerships, this tool will help to determine the impact of that regulation on your business case.
How to decarbonize your ship - Feeder + Shore Power
This is a techno-economic case study that provides guidance for decarbonizing a feeder by means of a shore power refit. Shore power will be made mandatory by 2030 for these ship types as per FuelEU Maritime regulation. A step-by-step approach is given to estimate costs, analyse technical feasibility, and create a business case for the shore power refit in general.
Optimize your FuelEU Maritime pooling strategy
The FuelEU Maritime pooling mechanism is complex. The FuelEU Pool Tool makes it simple. Use this tool to compare cost impact of FuelEU, EU ETS and the fuel itself when pooling up to ten different ships. Blend different quantities of fuel, change fuel properties and compare the cost outlook until 2050 to make your very own FuelEU pooling strategy.
FuelEU compliance penalty for all fuels
FuelEU is complex. The FuelEU Case Maker makes it simple. Use this tool to compare cost impact of FuelEU, EU ETS and the fuel itself for up to five different cases. Blend different quantities of fuel, change fuel properties and compare the cost outlook until 2050 to make your very own FuelEU strategy.
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.
