Ice Control

Addressing Unique Challenges

Sometimes unique challenges that need to be addressed with custom solutions.

One example is the A30 Ship Arrest system in Montreal. This was designed to protect the A30 bridge from large ships should they stray from the designated shipping channel. While the probability was low, the impact of a huge vessel hitting a bridge pier would be catastrophic.

Our Ship arrest system will stop a 35,000-tonne ship traveling at up to 3.5 knots from hitting the bridge. Our solution to this challenge was the only one that was accepted by Hydro Quebec and the St Lawrence Seaway.


A few of the special projects we've worked on.

Ship Arrest Boom

Ship Arrest Boom

We designed a ship arrest system that was built upstream of the recently constructed A30 bridge at Beauharnois, Quebec.

Oil City

Oil City

New pontoon and buoy designed to replace a boom designed and built by the US Corp of Engineers in 1984.

Ice Boom

Ice Boom

New cylindrical pontoons designed to replace previous booms 23km upriver that did not resist frazil ice.

Bark Lake All Season Safety Boom

In summer of 2006, an All-Season Safety Boom was designed, and constructed upstream of Ontario Power Generation's Bark Lake control dam located on the Madawaska River near Barry's Bay, Ontario.

Tailrace Safety Boom at Chats Falls GS

Past attempts have been made at installing a safety boom across the tailrace channel at Chats Falls GS without much success.

Debris Booms In Arrow Lake

The project consists of the design and supply of all components for a debris boom. The boom is to be installed upstream the canal of Arrow Lake Power Plant.

Debris Booms in James Bay

Two Debris Booms were designed, and constructed in James Bay on the Rupert River upstream of a spillway and a 2.9 km long Transfer Tunnel on the Lemare River.
