Reviving A Global Shipping Pier: Innovative Work at Quonset’s Port

Posted by Kimberly Walters on September 26, 2024

The Port of Davisville, located in North Kingstown, Rhode Island, has a rich history as a former Naval Air Station dating back to World War II. The Quonset Development Corporation (QDC), responsible for overseeing port operations, is undertaking a major project to rehabilitate Pier 1. Originally built during the 1940s, the pier has served its purpose for decades but now requires significant updates to support ongoing port activity.

J.F. Brennan Company (Brennan) was selected as the prime contractor for the project, tasked with carefully demolishing and reconstructing portions of the pier. “The overall objective is to allow the Port of Davisville to berth an additional car carrier on the south berth of Pier 1,” said Brennan Senior Project Manager Alex Baittinger. “The improvements we’re making will extend the life of this pier easily into the 2070s.”

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.

Portadam Installation at Hydro Dam: Innovative Solutions for a Changing World

Posted by Sam Stemper on March 04, 2024

We were contracted to replace flashboards and perform apron scour repairs at a hydroelectric dam along the Rock River in the Upper Midwest. Our client is a privately owned entity that owns and operates 80+ hydroelectric facilities throughout the United States.

The project’s significant goals involved increasing the dam’s retainage capacity, protecting the existing spillway structure, and providing an aesthetically pleasing spillway for the community's residents. This project was scheduled for the summer months when flow rates are at their lowest, mainly due to the volatility of the Rock River and the need for a slow-moving current to keep our divers safe.

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.

Repairing Fish Guidance Nets at a Hydropower Dam

Posted by Lauren Collins, Senior Project Manager on January 20, 2023

Our Pacific Northwest crew mobilized at a hydroelectric facility to repair a fish guidance net at Upper Baker Dam. Upper Baker Dam is 1 of 2 hydroelectric dams on Baker River, near Concrete, WA. The entire Baker River Hydroelectric Project covers nearly 300 square miles.

Upper Baker Dam, a 312-foot-high concrete gravity dam completed in 1959, has a floating surface collector system responsible for attracting and safely holding juvenile salmon for downstream transport around the dam. We supplied dive and topside support teams to assist the prime contractor with the recovery, disassembly, and installation of a new floatation collar on the existing barrier net. This is an essential repair to ensure safe fish passage around the dam.

Underwater ROVs: What Are They and How Are They Used?

Posted by Joe Baldoni on August 02, 2022

ROV stands for remotely operated vehicle. They are highly maneuverable unoccupied machines used to observe and work underwater, often in areas that are deemed too dangerous for commercial divers. ROV pilots can operate them from a nearby shore or boat.

Remotely operated vehicles are versatile tools commonly used in our industry to inspect, monitor underwater structures, and perform complex work tasks in depths divers cannot access. Although, more recreational ROVs are available with advancements in technology. These revolutionary machines are utilized by many industries to reduce costs to clients and keep divers safe in unknown or dangerous conditions.
