Our Projects - Moosonee, Ont.

Temporary Floating Docks, Marine Railway and Ferry Cradle:

Riggs Engineering was engaged by Ontario Northland to propose and design temporary floating docks for the ferry Niska, which provides service to Moose Factory Island and design a marine railway and ferry cradle for winter storage of the ferry at the Moosonee terminal.

The designs included 3-D hydrodynamic modeling of 50 km of the Moose River and a sediment re-suspension study taking into account peak tidal currents with and without boat/ferry motion. A design of underwater structures to withstand ice scouring and impacts was also undertaken, as well as soundings of the Moose River between Moosonee and Moose Factory Island.

Riggs Engineering provided the following services:

- Detailed design of the floating docks, marine railway and ferry cradle.

- Plans and specifications for all three contracts.

- Contract administration and residential site services.
