A.P. Moller – Maersk has rolled out a large-scale efficiency upgrade programme across its time-chartered container fleet. The initiative targets around 200 vessels operated by 50 different shipowners, aiming to reduce fuel consumption, improve cargo capacity, and cut greenhouse gas emissions.
Driving Sustainability and Cost Efficiency
The programme supports Maersk’s goal of reducing Scope 1 emissions by 35% by 2030 and achieving net-zero emissions by 2040. While transitioning to green fuels remains the long-term goal, retrofitting existing vessels offers immediate environmental and economic benefits.
Over 1,500 retrofit projects have already been launched, with another 1,000 planned by 2027. Key upgrades include:
- Propeller and bow replacements to improve hydrodynamics
- Pre-swirl devices for thrust optimization
- Waste heat recovery systems to reduce fuel use
- Shaft generators to lower auxiliary engine demand
- Structural changes to enhance cargo capacity and fuel efficiency
These upgrades are customized per vessel and are designed to lower operating costs by improving fuel efficiency and increasing container throughput.
Maersk is collaborating with shipowners to share retrofit costs, creating a mutually beneficial setup. Owners benefit from upgraded assets, while Maersk improves operational performance and sustainability.
Strategic Timing and Industry Impact
Many of the chartered vessels were built for higher-speed operations. As Maersk now operates at lower speeds for fuel efficiency, there is untapped potential in retrofitting older ships for current performance needs.
This programme allows Maersk to remain competitive while aligning with global emissions targets—without waiting for new, low-emission vessels to be built.
By 2027, Maersk aims to complete this extensive retrofit effort. The initiative marks a key step in balancing short-term efficiency gains with long-term decarbonization goals, reinforcing Maersk’s leadership in sustainable shipping.
