Officials for Argentina's Port of San Lorenzo are blaming the absence of tugboats for recent allisions, causing "billions" in damages.

"One of the biggest problems ... are that nowadays in the Port of San Lorenzo, the assistance of tug boats for vessels' mooring and unmooring is not compulsory," a port official told TradeWinds.

"In spite of being a service of accessible cost and offering security for navigation, the terminals that make up the port reject its mandatory use with the purpose of reducing port costs."
