Abstract
A system of floating canal sections that connect end-to-end along a route to form a shipping canal and contain brine to prevent freezing. The canal sections of the present invention resemble floating dry-docks that are filled with the brine solution rather than with normal sea water. Sections can be floated into place and connected. Sections can be anchored to the sea floor. A typical section can be around 1000 feet long, 150 feet wide and about 50 feet deep. The sections can be manufactured anywhere and towed to the Arctic and connected. The use of brine prevents pollution if there should be a leak.
Claims18
A canal system comprising:
- a plurality of floating canal sections connectable end-to-end, each containing a brine solution of sufficient concentration to prevent freezing down to at least −19 degrees C.;
- each canal section adapted to be towed to a location and connected to a previous section to form a continuous passageway;
- wherein, when said canal sections are connected end-to-end, they provide a continuous brine, all-year ship channel that resists freezing and allows ship traffic.
A method for creating a shipping canal in waters with a tendency to freeze comprising:
- providing a plurality of elongated floating canal sections each configured to hold a brine solution of sufficient concentration to prevent freezing down to at least −19 degrees C., and each having a gate at each end;
- towing each canal section into position and connecting said canal sections end-to-end to form a shipping canal;
- opening said gates;
- filling said plurality of canal sections with the brine solution.
An all-year ship canal configured to provide a northwest passage across Arctic seas comprising:
- a plurality of floating end-to-end canal sections sealed from ambient sea water containing a brine solution of concentration sufficient to prevent freezing in Arctic seas in winter, each canal section configured with a gate at each end and towed into position, each canal section adapted to be anchored to the sea floor.
