Fuel and compliance costs for offshore workboat in North Sea

Operating an offshore workboat in the North Sea area until 2050 will impose significant financial and operational pressure due to tightening environmental regulations and mounting compliance obligations. Modelling of compliance costs shows a clear tipping point in 2040, with FuelEU Maritime becoming the dominant driver, although FuelEU currently applies to vessels above 5,000 GT only. Results for a large offshore workboat operating year-round in the North Sea show that the maximum projected cost exposure could reach up to $250 million between now and 2050.

Business case for a Feedermax containership with a shore power battery

This case study evaluates a mobile shore power battery barge designed for a 1,730 TEU containership in the Port of Rotterdam. An average power demand of 329 kW and a peak demand of 1 MW is assumed. This results in the requirement of two 20-ft containerized batteries integrated into a Low Voltage Shore Connection (LVSC) system. Estimated savings for the ship reach €500 per 24-hour period, primarily due to reduced FuelEU compliance costs, which could exceed €600,000 over 10 years.

Choosing the right fuel: a brief guide to future prices and compliance costs

This case study analyzes 10 marine fuels using an HFO-equivalent model to determine their full lifecycle costs, including fuel prices and regulatory compliance costs, from 2025 to 2050. The results highlight a critical tipping point in 2040, driven by the FuelEU Maritime regulation increasing carbon intensity reduction targets sharply from 14.5% to 31%. This blog provides shipowners with guidance on how to navigate these evolving cost scenarios and maintain competitiveness to ensure future-proof investments.

FuelEU & EU ETS compliance costs for a 3,000 TEU Panamax containership

This case study determines the costs of compliance for a 3,000 TEU Panamax containership with respect to FuelEU and EU ETS. Estimated annual compliance costs for business as usual range from $2.5M in 2025 to $23M in 2050. Two different pathways are evaluated to determine mitigation options and OPEX costs: shore power and wind-assisted propulsion. Savings for shore power are approx. $400k per year in 2025, savings for wind-assisted propulsion are approx. $600k in 2025.

FuelEU pooling with full electric chemical tanker

This case study determines the effects of pooling a fully electric small-sized chemical tanker with similar type vessels in the context of FuelEU Maritime. The results show that a single electric ship can include up to 69 ships in its pool in 2025, each ship consuming 2,555 mT MDO per year.

What is the average shore power demand of a container ship?

Accurate estimates of containership power demand are becoming increasingly critical due to stringent regulations, such as FuelEU Maritime, in combination with technical complexities. Ship power demand varies significantly depending on size, onboard equipment installed, and operational profile. These uncertainties places considerable pressure on terminal owners, port authorities, and developers to design and implement shore power infrastructure. This blog aims to provide guidance on this issue.

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.

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.
