The Panama Canal has received the 'Cerro Ancon', the last of the 14 tractor tugs of its new fleet.
The new tugs replace the canal's older "mule" tugging system, which featured locomotives affixed to the concrete locks.
The new tug fleet will allow the canal to be more efficient and improve capacity as the third set of locks nears completion, said the Panama Canal Authority (ACP).
The tugs were built in Spain by shipyard Astilleros Armon. The vessels have been arriving one-by-one since mid 2013, with the Panama Canal now having a fleet of 46 vessels.
"The additional capacity will allow for the assisting of Post-Panamax vessels that will be transiting through the new locks, which will not require locomotives as used in the existing locks," said the ACP.
The new tugs are named after several geographical landmarks in Panama.
