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.

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.

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.

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.

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.

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.

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.

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.

The Corvus BOB (Battery On Board) is a standardized, class-approved, modular battery room solution available in 10-foot and 20-foot ISO high-cube container sizes. The complete system comes with battery, monitoring system, HVAC , TR exhaust, plus firefighting and detection system. The plug and play battery room simplifies integration into any system integrator’s power management system on board a ship. The battery cells have passive thermal runaway protection, and are type-approved according to DNV.

On May 10th, Port of Amsterdam awarded the contract for the realization of shore power at Cruise Port Amsterdam (CPA) to Powercon A/S and with BAM as subcontractor. Dick van Veen and Rick van Akkeren - BAM Business Unit Heavy Duty Charging - explain in detail about the project and the challenges that they are facing. Building the infrastructure that can host large cruise vessels and support the heavy electrical equipment is therefore a daunting task, all of which is discussed in this video.

During the lunch and learn, current forum Director Syb ten Cate Hoedemaker will exchange knowledge and experience from the usage of batteries within the shipping and offshore industries. You will learn which batteries will suit your vessel, plus discover the costs and payback for different operational modes. Which battery suits your vessel, your needs, your operational profile? This is the key question discussed in this lunch and learn with Maritime Battery Forum.

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.

Damen’s first all-electric harbour tug, the RSD-E Tug 2513, is a high-powered tug with 70-tonnes bollard pull, capable of manoeuvring even the largest vessels. It can undertake two or more assignments before being recharged, which takes just two hours. The battery pack size is 2,800 kWh, resulting an approximately 1,400 kW of charging power required. The battery pack is design for the vessel’s 30 year lifetime.

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%.

Watch this lunch and learn by EOPSA together with General Electric, in which we discuss the onshore and vessel aspects of shore power, including microgrids and using the Decarbonizer to determine the costs for shore power for your vessel.

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 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.

Ports are the start and end of every vessel’s journey. Because of this, onshore power supply undeniably plays a big part of the decarbonization of the maritime industry. Creating a network of onshore power supply in ports around the world is a tremendous but necessary task. One of the companies providing the technology for this transition is ShoreLink. Watch this lunch and learn by Shorelink, presented by Levan Chikviladze, to learn more.

Join Frank Nieuwenhuis, CEO of Econowind, as we discuss the VentiFoil®, sails of the 21st century. These devices can be installed on board existing vessels or newbuilds to reduce fuel consumption (or make you sail faster!)
