How Brennan Brought Lake George Canal Back to Life! [with video]

Posted by Sam Crawford, Project Manager on July 29, 2024

Brennan embarked on a vital restoration project for the middle section of the Lake George Canal. The primary goal was to protect aquatic organisms by separating them from contaminated sediment through a multi-layer sediment cap.

Initial Site Challenges

Hydrographic surveys revealed areas of varying slope and stability as the first layer of cap material was placed over the canal bottom. These issues were attributed to soft underlying sediment within the canal footprint. The success of this project hinged on effective collaboration between Brennan and the U.S. Army Corps of Engineers (USACE) to address these types of challenges.

Solving A Shore Power Problem: 6,100 Feet of Cable Delivers Clean Energy to Pier 66 in Seattle

Posted by Kimberly Walters on July 17, 2024

With the president of a leading cruise line committing to going green, offering shore power became essential for places like Pier 66. The purpose? For cruise ships to switch off their engines while docking and use electricity instead, conserving fuel and reducing emissions. This change would lead to cleaner air for Seattle and other ports adopting the same practice.

Procuring a Power Source for Pier 66

Pier 66 lacked a power source at that time, so the Port of Seattle began procuring one. The solution involved laying submarine cable on the seabed alongside Seattle's shore, linking Pier 66 to renewable energy from Seattle City Light. Here's how we did it.

Underwater Acoustic Deterrent System: Upgrades to Protect the Great Lakes from Invasive Carp

Posted by Kimberly Walters on January 18, 2024

We are at the Lock and Dam 19 facility in Keokuk, Iowa, operated by the U.S. Army Corps of Engineers (USACE). Our team replaced an 18,000-LB, 105-FT underwater soundbar with wet-mateable connections (cables and speakers that can be connected and disconnected underwater). This underwater acoustic deterrent system (UADS) upgrade allows divers to replace individual speakers if underperforming rather than continuing to remove the entire system.

Why? The U.S. Geological Survey (USGS) is spearheading a 3-year study to reduce the number of invasive carp moving toward the Great Lakes. It is the only study on the Mississippi River evaluating a deterrent for invasive carp.
