Decarbonising our operations

We all have a role to play when it comes to climate action. As a leading vessel owner and operator, we believe we can have a meaningful impact on protecting our planet by reducing our carbon emissions – but it is also clear that we need to coordinate and combine our efforts across the industry to succeed.

For this reason, Maersk Supply Service is taking an ‘All Steps Matter’ approach to reducing our emissions, proactively pursuing initiatives internally to decarbonise our fleet and operations, while also engaging collaboratively with our clients and stakeholders. We believe that even incremental measures are can add value to the overall effort.

Ambitious targets

Reduction in carbon emissions by 2028 (from 2018 baseline)

Our approach


Optimising the way we operate our vessels to reduce our emissions


Investing in fleet upgrades, both existing and developing technologies


Cooperative action with our clients and stakeholders for the greatest impact


Optimising our operations

Decarbonisation is not just a question of implementing new technologies. It requires a new emissions-oriented approach to how we operate our vessels. Through dialogue between our offshore crew and onshore colleagues, we continually run behavioural campaigns, seminars and webinars to educate, inform and share best practice throughout our organisation and reduce our emissions.


We are continually investing in a number of fleet upgrades to improve our environmental footprint, from Variable Frequency Drives and energy storage systems to hull cleaning solutions and Vessel Performance Management Systems. While we go as far as we can with existing technologies, we are also exploring emergent solutions.

The world’s first hybrid-electric anchor handler

In 2022, our Norwegian-flagged anchor handler Maersk Minder was retrofitted with a container-based battery system built by Wärtsila.

Customer collaboration

Besides proactively pursuing initiatives internally to decarbonise our fleet and operations, we are also engaging collaboratively with our clients and stakeholders.

No one individual, company or organisation can solve the climate crisis alone – the scale is global and it will require a collective effort to devise a global solution. But through partnerships and urgent cooperative action, we believe we can make a real impact.

10 Principles to Decarbonise the OSV Industry Whitepaper

Leading the OSV industry towards a net-zero future

We have been proud to participate in the Forum for Decarbonising the OSV Industry, engaging directly with major players in the offshore energy sector such as Chevron, Shell, TotalEnergies, Equinor, and ABS. The Forum aims to foster dialogue among vessel owners and charterers, enabling us to leverage a collective and focussed effort to reduce OSV carbon emissions. In 2022, the Forum published its first whitepaper, containing ten agreed-upon principles for concrete actions that can be taken across the industry.

ECO Offshore: supporting our customers with the option of biofuel

Biofuel has been successfully trialled aboard our vessels as a viable alternative that does not compromise on safety or performance. We are therefore delighted to be able to offer our customers the option of adding ECO Offshore to their contracts: a carbon-neutral operation using sustainable fuels, providing a green option to decarbonise their operations and value chain.
