The boat MSC OSCAR, which can carry 19,224 containers and is four football fields long, is registered in Panama

"It is the most efficient ship on the planet," said Diego Aponte, general manager of the Mediterranean Shipping Company (MSC). "It carries 35 percent more cargo, but uses 35 percent less fuel. The efficiency gains are, therefore, enormous."

The AMP said it "is proud that the the world's largest container ship carries the national flag of Panama."

The agency said this was achieved through its efforts to strengthen security and modernize its merchant marine processes in compliance with international conventions.
