Maersk overhauling chartered fleet in fuel-saving push

October 9, 2025 |

In Denmark, A.P. Moller – Maersk announced it is retrofitting around 200 vessels in its time-chartered fleet, working with 50 shipowners to install fuel-saving and cargo-boosting upgrades aimed at lowering the cost of moving each container, also known as slot cost.

According to Maersk’s Head of Asset Strategy and Strategic Partnerships at Maersk, Ahmed Hassan, “By working closely with our partners, we aim to implement solutions that not only reduce emissions but also enhance the overall competitiveness of our fleet.” The effort supports the company’s target of a 35% absolute reduction in scope 1 greenhouse gas emissions by 2030 from a 2022 baseline.

So far, more than 1,500 individual upgrade projects have been completed across these ships, with 1,000 more underway. The upgrades include replacing bulbous bows and propellers to reduce drag and improve thrust, as well as adding heat recovery systems and shaft generators to cut fuel use.

Other changes aim to carry more cargo per trip, such as raising lashing bridges, strengthening hulls for deeper drafts, and improving the ships’ loading software. Hassan called the cost-sharing model “a win-win,” noting owners get longer-term vessel value while Maersk reduces emissions and fuel bills.
