Unique vessels – Special capabilities and focus
More than 90% of our current CO2 emissions come from fuel consumption onboard our vessels. Additional emissions sources include seafarers’ travel, transport of goods and heating and electricity to our offices and yard facilities. As our vessels account for the vast majority, we will focus our initial efforts here.
Our vessels have powerful engines and perform a variety of work scopes. Our anchor handlers specialise in towing and mooring operations. These vessels perform a variety of work scopes, including long-distance ocean towing, anchor-handling work and other activities within mooring work scopes, as well as long periods of precision station keeping in a specific location (dynamic positioning operations), and periods of navigating “light ship” to/from work locations. Whilst careful planning can significantly reduce fuel consumption, the diverse nature of these different operational work scopes increases this complexity and challenges us to find solutions to optimise our fuel consumption in a variety of situations. Nonetheless, we have challenged ourselves to put a focus on decarbonisation across all our operations, no matter the work scope.
At Maersk Supply Service, we took a significant step forward in our decarbonisation journey during 2018. At that time, we introduced a program to increase the awareness of energy efficiency amongst our workforce – with a special focus on providing our seafarers with the awareness and tools to best manage our fuel efficiency. On some vessels, we reduced fuel consumption by more than 10% compared to similar types of operation modes. Whilst more work can be done, we are proud to have seen a significant improvement in the first 1+ years of this initiative.
We have also placed a strong focus on technological solutions to this global challenge. Our teams have been focused on vessel upgrades, such as the installation of hybrid battery solutions, more efficient (variable) frequency drive retrofits, and the use of biofuels where feasible, as examples. With a sharp focus on innovation, we are committed to achieving more in this space. Some of the key elements that we are focusing on are illustrated below:
