The ferry company DFDS - which wants to take over from Condor - is carrying out berthing trials in both St Helier and St Peter Port today ( 3 October).
DFDS is one of three companies whose bid to take over the Channel islands passenger and freight operations is being considered by the governments of Jersey and Guernsey.
An announcement is expected soon.
A statement from Jersey's government said the trials had been commissioned 'as part of ongoing testing of contingency plans for a number of possible risks, of which supply links naturally form a key part."

The Seven Sisters normally operates the Newhaven to Dieppe cross Channel route.
It is 469 feet or 143 metres long and can carry 600 passengers, around 220 cars and 50 trucks. It was commissioned in 2006.
The Danish shipping and logistics company berthed a longer freight vessel in both ports in December 2023.
The Finlandia touched the wall of St Peter Port harbour during that trial.
