The UK will spend more than £100m chartering extra ferries to ease "severe congestion" at Dover, in the case of a no-deal Brexit.
Over the last few months, additional ferry contracts were awarded to French, Dutch and British companies.
The contingency plans allow for almost 4,000 more lorries a week to come and go from other ports, including Plymouth, Poole, and Portsmouth.
Lib Dem leader Sir Vince Cable called the move "complete madness".
"The government has the power to stop "no deal" at any time but instead is spending millions on last minute contracts," he said.
"The fact that this money is predominantly going to European companies is nothing short of ironic, reducing Britain to a laughing stock on the global stage."
The Department for Transport (DfT) said the awards were "a small but important element" of its no-deal planning.
