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.

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.

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.

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.

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.

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%.

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.
