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.

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.

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.

Project BOEI - Lunch and Learn

On behalf of the Province of South-Holland, Sustainable Ships has been project leader of 'Project BOEI’, a techno-economic feasibility study on the electrification of tankers off the coast of Scheveningen, Netherlands. The study was performed with consortium members InnovationQuarter, Bluewater, Knutsen, EOPSA, Rijkswaterstaat, Campus@Sea, Port of Rotterdam, KVNR and Cavotec. This lunch and learn is the recording of the close-out session in which main findings were presented.

Project BOEI

Project BOEI is a techno-economic feasibility study on behalf of the Province of South-Holland on the electrification of tankers at the Scheveningen anchorage. The goal is to identify the most feasible technical solutions and risks, in addition to cost and emissions reduction estimation. Primary drivers are reduction of NOx and CO2 emissions. Total costs for all scopes combined is €14M (~€12M for infra and ~€2M for ship). E-anchor and subsea cabling are approximately 50% of all cost. Break-even price parity for shipowner and provider of power is at around €0.20-€0.25 per kWh.

Ship-Based Carbon Capture Techno-Economic Guide

This blog provides techno-economic guidance for the use of SBCC onboard your vessel, including operational impact, logistics and of course the costs for implementation. Key points include the following; SBCC is applicable to virtually all ship types, sizes and fuel type but LNG is preferred. SBCC produces 2 m3 of CO2 per day per MW. SBCC costs €115 per ton CO2, is a CAPEX dominated technology and costs €175k per MW.

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.

COSCO 700 TEU Full Electric Container Ship

The N997 has two propulsion motors with a capacity of 900 [kW] each and a total battery capacity of 50 [MWh] - best estimate currently available. The 120 meter long ship has a fully electric drive, can carry up to 700 TEU and is able to swap battery packs en route. The vessel is designed for Chinese inland and coastal waters, covering over 600 nautical miles of routes on the Yangtze River.

MoU for North Star Support Vessels on Offshore Wind

Maersk’s Stillstrom and North Star have signed a Memorandum of Understanding (MoU) to accelerate the adoption of offshore charging and vessel electrification technologies for Offshore Support Vessels (OSVs) in the offshore wind sector. Offshore charging hubs will enable the vessels to recharge their battery systems using wind energy while in the field.

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.

Neste Renewable Diesel Handbook

Neste Corporation calls its own HVO product “Neste Renewable Diesel”. The common acronym “HVO” comes from the terms “Hydrotreated Vegetable Oil”. It meets the requirements of EN 15940 for paraffinic diesel fuels and is allowed as a blending component in EN 590 B7 diesel fuel. It is a high quality fuel that can be used to enhance the properties of the final diesel blend. No modifications to vehicles required and it has the same torque and maximum power as with fossil diesel fuel in modern engines.

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.
