Immersion pontoon IVY passes final test and receives approval
The immersion pontoon IVY has passed its final tests and is now approved by the Danish Maritime Authority. Therefore, the contractor Femern Link Contractors (FLC) can begin preparing to immerse the first tunnel element into the dredged tunnel trench off Lolland’s coast this spring.
The special vessel IVY is comprised of two distinct units: IVY 1 & 2. Prior to the transportation and immersion of a 217-metre-long standard tunnel element, each end is securely attached to IVY 1 & 2, which provide buoyancy. For the handling of the 39-metre-long special elements, IVY 1 & 2 are joined to form a single vessel, facilitating the immersion process. Together, IVY 1 & 2 are equipped with 23 kilometres of steel wire spread over 66 winches, enabling them to submerge tunnel elements to depths of up to 40 metres with exceptional precision.
