The story of the Madrid Maersk
The Madrid Maersk was the first container ship ever delivered with a capacity above 20,000 TEU, opening the 20k club in April 2017. Lead ship of Maersk's second-generation Triple-E class, it doubled down on the design philosophy that made the original Triple-E famous: capacity and fuel efficiency prioritised over top speed, with a hull and engine layout optimised for the slow-steaming era. Its eight years of verified MRV data make it one of the best-documented ships of the 20,000 TEU generation.
