BC Ferries Quathiaski Cove Docking Pontoon
Marine Structures
The new Quathiaski Cove terminal was designed to use existing components that were left over from the old Bear Cove terminal. The main components, pontoon, ramp, and apron, had to be reworked to suit the new design. The biggest challenge of the project was getting the existing steel components onto dry land to carry out the addition and modification work.

The pontoon being hauled out. Note that the port side cradle catwalk had to be removed (you can see the bolt holes on the deck) to accommodate the pontoon width. Also note the close clearance between the pontoon and the storage buildings that the Point Hope crew are watching. February 10, 2010 ![Working scaffolding surrounds the shore side of the pontoon]()
Working scaffolding surrounds the shore side of the pontoon where we had to cut out damaged areas where the old mooring piles had crushed the structure. Portions of the bulkhead, stiffeners, deck, and side plates had to be replaced. February 15, 2010 ![Installing support steel for a new pedestrian walkway on the starboard side of the ramp.]()
