Maersk Triple E-Class

The Maersk Triple E-Class

Welcome to the dedicated page for the Maersk Triple E-Class, a series of some of the largest and most advanced container ships in the world. These vessels are renowned for their impressive size, efficiency, and environmentally friendly design.


Name: Maersk Triple E-Class
Type: Container Ship
Year Built: 2013 onwards
Builder: Daewoo Shipbuilding & Marine Engineering, South Korea
Owner: Maersk Line
Specifications: 165,000 GT, 1,312 ft length, 194 ft beam, 52 ft draft
Capacity: Approximately 18,000 TEU (Twenty-foot Equivalent Units)
Speed: 23 knots (maximum)

Construction and Design

The Maersk Triple E-Class was designed to be the most efficient and environmentally friendly class of container ships. The “Triple E” stands for Economy of scale, Energy efficiency, and Environmental improvement.

Key Features:

  • Hull Design: The hull is optimized for maximum cargo capacity and fuel efficiency, with a U-shaped design that allows for more containers to be stacked and reduces the resistance through water.
  • Engine Efficiency: Equipped with twin-skeg engines and two propellers, the ships are designed to operate at slower speeds, which reduces fuel consumption and emissions.
  • Environmental Impact: The ships incorporate numerous green technologies, such as waste heat recovery systems and energy-efficient engines, reducing CO2 emissions by 20% per container moved compared to previous models.

Operational Role

The Maersk Triple E-Class ships are a key component of Maersk Line’s global operations, primarily serving the Asia-Europe trade route. These ships play a crucial role in the efficient and reliable transportation of goods across the world’s oceans.

Key Routes:

  • Asia to Europe: The primary route for Triple E-Class vessels, facilitating major trade between these regions.
  • Other Routes: Occasionally deployed on other global trade routes depending on demand and operational requirements.
