In response, Wightlink contracted Ekspan to remove, refurbish and re-install the
linkspan approach ramp. These works had to be carried during specific night shift
closures (Sat 23:00 - Sun 06:00) enabling the ramp to still be operational during theday causing minimal disruptions to ferry crossings.

The first night shift involved a team of Ekspan operatives to remove barriers to the
approach ramp. The hinge assembly was cut from the linkspan by gas torch enabling the final lift and removal of the linkspan approach ramp, which weighed over 10 tons.
Once removed, the ramp was transported back to Ekspan works for refurbishment.
During this closure, temporary barriers were positioned in place of the ramp gate
barrier and temporary ramp sections (4 no. bespoke trench mats) were installed.

Refurbishment of the linkspan ramp involved; removal of antiskid, existing hinge
bracket assemblies and damaged barrier fixings; repair and replacement of pivot
plates, pins, brackets and connections where necessary; trim and welding of new
bracket assemblies; shotblasting of both ramp sections and remedial work required
to steel structure. A full paint system was applied followed by re-application of anti- skid to all upper surfaces.

Removal of the temporary barriers and temporary ramp sections were carried out
during a second night shift, followed by the re-instatement of the refurbished linkspan approach. Works here included site preparation and welding of the new bearing assemblies to the existing linkspan. Grease pipes were installed on a final visit in between ferry arrivals/departures, when tidal conditions were deemed suitable, allowing the new hinge assembly to be lubricated and maintained.

 

Despite the very tight working constraints, Ekspan successfully delivered this installation on time and with no disruption to ferry services.
