Brittany Ferries has celebrated the second milestone in the build of its next ship Honfleur with the keeling laying - the lifting into place on the slipway of the hull sections of the LNG cruise ferry.
The first milestone was the steelcutting ceremony which preceded the construction of the hull sections. Coins were also placed in Honfleur’s keel by representatives of Brittany Ferries and builders FSG as a token of good fortune.
“Technology has transformed the way we design hulls,” says Heike Billerbeck, head of ship theory and hydrodynamics at FSG. “Over the last 20 to 30 years we’ve reduced wave resistance by between a third and a half.” Heike and her team spent around three months creating a digital model of Honfl eur’s hull, and testing it using computational fl uid dynamic software. This allowed them to visualise the size and angle of the bow wave and wake the ship will create: smaller waves mean less wasted energy. They also created animations of how Honfleur will perform in heavy seas as well as calculating exactly how much power the ship will need to sail at a given speed, ensuring she meets effi ciency targets set by Brittany Ferries.
The shape of the hull has a signifi cant impact on a ship’s manoeuvrability in port and its stability at sea. A good design reduces vibration that can sometimes be felt from the propeller which means Honfl eur will be a more comfortable ship, as well as being better for the environment.
