On Monday, August 12, 2019, Weeks Marine, Inc. christened the most highly automated and multifunctional ocean-going U.S.-flag vessel in its category, J.S. Chatry, at a ceremony in Houma, LA. Invited guests and selected media representatives toured the 310 ft. dredge, followed by a program introduction by Eric Ellefsen, President, who spoke about Stephen Chatry’s contributions to the company, saying, “His steady leadership has been the key to the Weeks Dredging Division’s growth over the last two decades.” Among the guest speakers were Louisiana State Senator Norbert (Norby) Chabert who welcomed the J.S. Chatry to the Louisiana dredging market, and the Coastal Protection and Restoration Authority’s (CPRA) Chairman, Chip Kline, who mentioned that he was pleased to hear that the J.S. Chatry’s first project would be in the Mississippi River at the Hopper Dredge Disposal Area.
Richard Balzano, Deputy Maritime Administrator at the U.S. Maritime Administration, commented, “the U.S.-flag maritime industry is thriving today, due in part to the creativity, leadership, and entrepreneurial spirit of companies like Weeks Marine and all its partners.” Rich Weeks, CEO, also spoke, honoring his father Dick for being the mainstay of Weeks Marine during its first hundred years and for laying a sound foundation for the next hundred. He thanked Weeks’ many partners and suppliers and closed by thanking Steve for his 21 years of service to Weeks Marine and for helping the company achieve sustainable growth. Steve’s daughter, Amanda Chatry, closed out the program by breaking a ceremonial champagne bottle over the dredge’s 8.5’ cutterhead.

INTRODUCING J.S. CHATRY
The $60 million investment in this new oceangoing 30-inch hydraulic cutter suction dredge will strengthen Weeks Marine’s presence in the national coastal restoration and protection market, one of the fastest growing in the dredging industry. The dredge, named for J. Stephen Chatry, Vice President and head of Weeks’ Dredging Division, embodies the technical advances of modern dredging.
The most cutting-edge U.S. vessel in its category, J.S. Chatry will be able to dredge a wide variety of materials, including cemented sediment, clay, and sand, all while meeting federal environmental standards. The ability to dredge nearly all types of soils and rocks that are ill-suited for trailing suction hopper dredges and mechanical dredges gives cutter dredges an advantage over their counterparts.
“I am very happy and proud that our newest dredge is named for Steve. He is a lifelong Louisianan and has been a key member of our team as we have grown the business in Louisiana and throughout the United States,” said Rich Weeks, CEO.
J.S. Chatry will be powered by GE’s Tier IV diesel engines, and boasts a total installed horsepower of 22,264 with 3,000 hp on the cutter-head. The 310-foot-long, 72-foot-wide dredge is a testament to technical and engineering advances, which are highlighted when compared to one of Weeks’ first cutter suction dredges, Venture, built in 1958.

“The power electronics and automation in the J.S. Chatry are a huge step forward. These advances allow precise control of the dredge functions which help us maximize productivity. It also has a more efficient sliding spud carrier built into the hull,” said Shane Harris, Senior Project Manager/Senior Electrical Engineer. “And the Tier IV (emission standard) hits the highest EPA rating for environmental efficiency compliance requirements,” said Harris. Charlie McCaskill, Vice President in the Dredging Division, noted some of the technological advancements over the Venture, including more than twice the dredging depth, three times the pumping distance, four times the swing power, five times the cutter power, and a walking spud system versus one that is fixed. Another noteworthy advancement of J.S. Chatry is its ability to work offshore. “One of our design parameters was to build a vessel that has better seakeeping ability,” McCaskill said. “As sea conditions worsen, a dredge will obviously have to stop digging at some point. We wanted a vessel that could continue working in rougher sea conditions compared to the other dredges in our

fleet.” When the dredge is not at sea, J.S. Chatry is equipped with a walking spud carriage for efficient work in inlets and navigable waterways. In October 2019, J.S. Chatry joined ongoing dredging work at the Head of Passes project in the Mississippi River Ship Channel near Venice, LA. Weeks Marine will dredge 12 million cubic yards from the existing Hopper Dredge Disposal Area, to create an additional thousand acres of wetland in the Delta Wildlife Refuge, Pass A Loutre Wildlife Refuge, and the New West Bay marsh creation area. “J.S. Chatry is the next advance in technology, efficiency, and productivity,” said Eric Ellefsen, President. “I am excited about what it means for both Weeks Marine and for the capacity of the nation’s dredging industry.” The coastal protection and restoration markets are growing, and the addition of the J.S. Chatry is a strategic decision to further our commitment to the dredging industry.
INTRODUCING J.S. CHATRY
Expanding into Dredging Weeks Marine expanded its operations to include dredging around the 1950’s, utilizing its cranes initially used for stevedoring operations - to move into the new market. It wasn’t until later that the company acquired its first cutter suction dredge, Venture, built in 1958. The use of suction dredges can be traced back to 1867, when French engineer Henri-Emile Bazin suggested the use of pumps for dredging rivers, leading to the development of the first suction dredges that were used in building the Suez Canal. Suction dredges became more common following the successful completion of this vital channel in 1869. By the end of the 19th century, the cutter head was developed to deal with harder soils and rocks, overcoming the limitations of traditional suction dredges.

Weeks’ Canadian subsidiary, McNally International, Inc., has been awarded a subcontract for the Cherry Street Lake Filling (CSLF) Project, one part of a much larger revitalization program for the Port Lands of Toronto. This area, immediately east of downtown Toronto, represents over 1,000 acres of under-utilized real estate. The program will seek to restore the mouth of the Don River and create a new river valley for channeling flood waters. As part of this project, new wetlands will be created along with a new community called Villiers Island. McNally’s subcontract represents approximately $6 Million of the $65 Million CSLF project, which in turn is part of the overall $1.25 Billion Port Lands Flood Protection Project. Figure 1 shows the concept rendering of the proposed finished product, with the front face of the revetment we are working on highlighted in blue. McNally’s subcontract involves the placing and shaping of aggregate materials for this revetment stretching from the end of the existing Keating Channel to the outer edge of Pier 35, covering a distance of approximately 325 meters. Included with the revetment work is the installation of fish gate structures and marine landscaping. Figure 2 shows the status of the work in November 2018. In this image, you can see the core stone starting to take the shape of the revetment and the reclamation fill being placed by others behind it. The inside slope of the revetment was completed first and covered in geotextile so that the reclamation fill could be placed prior to McNally completing its work. The revetment installation began with several large cargo vessels bulk placing core stone near the revetment site. After this, a total of approximately 25,000 cubic meters of core stone was relocated and/or shaped to form the base of the revetment. This is a significant increase over the contract quantity of only 10,000 cubic meters due to issues with the placement accuracy from the cargo vessels.
CHERRY STREET LAKE FILLING PROJECT
Figure 3 “Drowned Tree” with concrete anchor
As the bulk placement was not within the contract, a significant change order was negotiated for the increased quantity, thus increasing the project budget. After areas of the core stone were approved, subsequent layers were placed consisting of an additional 11 types of material totaling over 15,000 cubic meters. These layers include armor stone for protection of the revetment, habitat stone for fish habitat, and landscaping materials such as beach gravel. The level of detail required by the architects is significant, with various cross sections and layers, some of which will not be easily visible to the public. Unique to this project are some of the marine landscaping requirements, which include the planting of Drowned Trees and placement of Rootwads around the structure. Figure 3 shows the design for the Drowned Tree, which is a dead tree with a concrete anchor buried in the core stone to hold it upright. Figure 4 shows the mock-up of the Rootwad, which is a tree trunk with the roots still attached, anchored by boulders. The purpose of these is to create a natural looking wetland similiar to what is seen in Figure 5.

Work remains on schedule with the bulk of the in-water work completed in September 2019 with final shore work finished in October. However, the overall project will still have several more years before it reaches completion. With this remaining work, there may be potential for additional marine based contracts to bid on depending on the final designs for the remaining sections.

Healy Tibbitts Builders A WEEKS MARINE COMPANY
COLLABORATION OF DIVISIONS
Weeks Tugboat Carolyn Fully compliant with Subchapter M regulations A joint effort by Weeks’ Marine Services Division, Regulatory Compliance, and Healy Tibbitts Builders, Weeks’ Hawaiian subsidiary, has successfully brought the Hawaii-based tugboat Carolyn into Subchapter M compliance. The U.S. Coast Guard’s (USCG) Subchapter M regulations govern the design, construction, equipment, safety protocols, certification, records, and operation of towing vessels. Weeks Marine continues to lead the way in achieving compliance with these enhanced safety standards for its towing fleet. In January 2019, a team comprised of Ronnie Clifford, Safety & Compliance Officer - Towing, Steve Brunswick, Regulatory Compliance Officer, and Kevin Pointer, Regulatory Compliance Specialist, traveled to Hawaii and met with John Juettner, Equipment Manager, Jeremy Aguiar, Deckhand, Cristian Caicedo, Marine Operations Manager, and Captain Scott Cooper of Healy Tibbitts to begin the evaluation for Subchapter M regulations. The week-long visit consisted of extensive time spent aboard the Carolyn and a deep dive into the vessel’s operations and records. Together, they were able to gather clear objectives and action items to ensure the Carolyn would be ready for its USCG inspection to determine Subchapter M compliance in March 2019.
Following the visit, Marine Services and Healy Tibbitts worked tirelessly to create a Health and Safety Manual and other necessary documents for compliance with Subchapter M regulations. The vessel also underwent its dry docking requirement, whereby a towing vessel must be dry docked twice within a five-year period to further ensure that the vessel meets the applicable safety standards. In March 2019, Ronnie Clifford returned to Hawaii with Chuck Cobb, Regulatory Compliance Supervisor, and Bryan Rolig, Regulatory Compliance Specialist, to train the crew of the Carolyn, including running through drills and readying the vessel for its upcoming inspection with USCG. The USCG inspector acknowledged the excellent condition of the vessel and routed the Certificate of Inspection (COI) to the Captain of the Port for approval. As a result of the collaborative efforts of Marine Services, Regulatory Compliance, and Healy Tibbitts, the Carolyn was issued its COI in May 2019 and is in full compliance with Subchapter M. Other vessels in Weeks’ fleet that have been issued their COI in 2019 are the Elizabeth, Katherine, Thomas, and Alexandra.

Tappan Zee Bridge Tarrytown, New York
WEEKS MARINE, INC. Âˇ FALL 2019
WEEKS 531 working in close quarters between the new and old Tappan Zee bridges.
Weeks Marine played a significant role in building the bridge pier protection system for two main piers of the Tappan Zee Bridge in 1998 and later in its demolition and disposal in 2018. Spanning the Hudson River in New York, this vital thoroughfare connected Rockland and Westchester counties and served hundreds of thousands of travelers each day. Weeks Marine, with joint venture partner Grow Tunneling (now a part of Kiewit), constructed the bridge pier protection system from designs provided by URS Greiner from 1998 to 2000. A total of 56 precast T-beams were installed on a foundation of 96, 48-inch diameter pipe piles. These steel piles were driven up to 140-feet into the riverbed, with the final capacity of each pile between 500 and 750 tons. Once all the precast was in place, closure pours were made to connect the precast. Watertight cofferdams were installed around the post-tensioning ducts. The bundled tendons, ranging from 206-feet- to 361-feet-long, were installed and jacked to 360 kips (1 kip equals 1,000 pounds-force). A mini-batch plant was set up on the barge for grouting the tendons. Following the post-tension work, Weeks and the Grow Tunneling teams installed handrails, ladders, stairs, and ultra-high-molecularweight polyethylene facing on the exterior of the fenders, completing the project.

On October 6, 2017, the Tappan Zee Bridge was officially retired after 62 years of service and the new 3.1-mile state-of-the-art, twin-span Governor Mario M. Cuomo Bridge was opened to the public. Weeks Marine returned to the site of the iconic bridge, now standing beside the newly constructed bridge, to demolish and remove the pier protection system. The planning phase and removal of the precast fender panels and supporting steel piles at the main span of the Tappan Zee Bridge presented unique challenges for Weeksâ€™ engineers and 15-member demolition crew. One pre-demolition issue was how to gain access to sections of the fender system located beneath the low-lying bridge. An engineer-designed ballast barge with a forklift-like structure, one of the largest ever to be built by Weeks Marine, was the answer. When the ballast tanks were filled with seawater, the end of the barge with the forks sunk below the fender structure. Two tugs then slid under the fender structure and the ballast was reversed by pumping it back to the other end.
TAPPAN ZEE BRIDGE
This action enabled the section to be towed from beneath the bridge to a crane, which then lifted the section onto a deck barge. Engineers also had to calculate how to safely move the 300 to 450 ton sections onto the barge. The solution led to a company first – the deployment of the W531 to metro New York. Based in Louisiana, the 500-ton capacity Clyde 42 floating crane is one of the largest in the company’s fleet and was towed to New York just for this job, according to Dru Kish, Project Manager. “The 420-foot-long, 100-foot-wide working-offshore crane sits 19 feet out of the water and can house up to 100 workers,” Kish said. “It was the first time it was in the Hudson/New York area for Weeks Marine. It normally works in the Gulf region.” Engineers wanted to ensure that the W531 would fit in the tight space between the new and old bridges. Rhino 3D technology was used to accurately and effectively position the crane between both bridges. The 3D model demonstrated that the boom and its A-frame could, in fact, rotate 360 degrees without colliding into either bridge.

Once work began, employees of the subcontractor Cutting Technologies International, Inc. (CTI) used a diamond-encrusted wire to cut through the concrete. “Once the cut was made, a diver would put the wire around the pile at its base and cut it off,” according to Ed Soehngen, Project Superintendent. The special barge was then moved into position to access one of the 16 cut sections to be removed from under the bridge. “The CTI crew really did a fantastic job for Weeks given the challenges they faced,” noted Kish. After all the concrete sections had been removed, divers experienced several problems above and below the river’s surface. Extreme cold weather which created large ice chunks on the river prohibited divers from accessing the pilings for six weeks. After conditions improved, sandy sediment at the mudline sank back into place every time divers tried to create the necessary angle to cut the pilings. The solution was to utilize a clamshell bucket on a crane to excavate an area around the pilings, enabling divers to access the piles at the required elevation.

A total of 17,500 tons of concrete, steel pipe pile, and steel beams from the superstructure were used to create five artificial reefs around Long Island. Working in cooperation with the New York Department of Environmental Conservation, a reef barge transported materials to GPS-specific locations and offloaded them to create artificial habitat and spawning sites for aquatic life. New fishing opportunities were established at Fire Island, Hempstead, Moriches, Rockaway, and Shinnecock reefs during the 15-month reclamation project. “I’ve said many times that this is a real win-win for everyone,” said Ed O’Donnell, Transport and Disposal Superintendent. “It creates an aquatic habitat and repurposes materials that meet federal standards that would otherwise end up in a landfill. The fishermen really love this, too.” An additional 84,000 tons of concrete was crushed into tiny pieces and used as fill at North American Aggregates, a subsidiary of Weeks Marine based in Perth Amboy, NJ.
TAPPAN ZEE BRIDGE
The concrete recycled at the site helped rehabilitate and meet Federal Emergency Management Agency standards for restoration of shoreline destroyed during Hurricane Sandy and to raise grade at the Perth Amboy site. With the demolition and removal of the fender structure now complete, this project has come full circle for Weeks Marine. Weeks Marine employee Frank Campion was fortunate to be involved with the original build as well as the demolition of the fender system. “It was interesting to build and to deconstruct, and I actually thought I’d never be around to see it come down,” Campion said. “It’s not often you get to be involved with both ends of a project.”

North American Aggregates’ (NAA) transformed the vacant site in Perth Amboy, New Jersey purchased in 2016. The new material processing plant has been under construction since June 2018 and officially opened in October 2019. During construction, the site was strategically utilized to continue the processing of sand, and the plant can now process 1,500 tons of material per hour, tripling the current production rates. The process begins with NAA’s trailing suction hopper dredge, Eleanor, mining virgin source aggregate from the Ambrose Federal Navigation Channel. The ocean mined sand is then transported to the Perth Amboy facility where it is drawn into the process stream. It is then conveyed to specialized heavy-duty wet screens, blending and mixing stations, rinsing areas, and stockpiled over two reclaim tunnels and product load-out areas. The state-of-the-art material processing plant is equipped to be a one-stop-shop for aggregate supply.
The fleet of 982M wheel-loaders cuts loading time by one third.
Developments will continue in Perth Amboy with the addition of two new E-cranes, currently in fabrication in Belgium. Utilizing electricity for operation, the E-canes will increase unloading the Eleanor in under five hours.
