Further delays to the GBP 70 million ferry port scheme of the Manx government in Liverpool UK are likely due to recent poor weather, according to the Manx infrastructure minister.
Construction of the new ferry terminal at the Princes Half Tide Dock was due to be completed in June.
Chris Thomas said the House of Keys marine work to protect the quay wall had been delayed by high winds creating a "testing environment".
He added there was also a risk the project could again go over budget.
Costs have spiraled over the last 4 years as the estimated completion date has slipped back.
Initially, Tynwald approved a budget of GBP 38 million for the new terminal back in 2019, when ministers hoped it would be finished by the end of 2020.
The COVID crisis and other issues saw costs double and also led to delays.
Mr. Thomas said ~30% of the scour protection work in the river, designed to limit damage to the quay walls caused by ships, had been completed. However, high winds earlier this month had made it difficult to use the crane needed for that part of the project, he added.
Once finished, the site is expected to accommodate up to 1,000 passengers sailing between the Isle of Man and the United Kingdom.
In an update to the House of Keys, Mr. Thomas said that though buildings on land were "progressing well", the delays to marine works meant the scheme might not be ready by the summer.
Some MHKs raised concerns this might have a "knock-on impact" on the ferry schedules of the Isle of Man Steam Packet.
According to Mr. Thomas, his department had been in "regular dialogue" with the public ferry operator to minimize disruption.
