LA CROSSE, Wis., December 21, 2020 ― Nelosca Technologies (Nelosca) officially announces the asset acquisition of New England-based Specialty Diving Services, Inc (SDS). The acquisition combines two established union companies that specialize in commercial diving and heavy marine construction.

The Interstate Island Avian Habitat Restoration Project is listed as one of the many Areas of Concern (AOC) projects within the Great Lakes. Interstate Island is a small parcel of land located within the Duluth-Superior Harbor along the St. Louis River Estuary. Due to rising water levels, the island has shrunk in size by half in recent years, and along with-it important wildlife habitat has disappeared. The need to restore the rare avian habitat on Interstate Island has been a priority for years, and it came to fruition in 2020.

102 years of lateral earth pressure and deterioration at Pisgah Dam caused its existing spillway wall to lean. Partnering with private dam owner Otter Tail Power Company, Nelosca ensured their hydropower dam received necessary repairs. The project included concrete demolition and the replacement of the dam's north spillway wall over two years.

LA CROSSE, Wis., October 28, 2020 — Nelosca Technologies (Nelosca) announces certification in occupational health and safety management, quality management, and environmental management, in accordance with the International Organization for Standardization (ISO).

The Federal Energy Regulatory Commission (FERC) regulates the transmission and wholesale sale of electricity in the United States. An important duty of FERC is to monitor conditions of the more than 1,700 non-federal, electricity-generating dams in the US. They also set standards that hydropower project owners must follow to ensure the safety of the general public. This includes mandating regular inspections of hydropower projects to certify they are in sound condition and comply with the Commission’s safety standards. Owners not in compliance with the Commission’s inspection standards risk losing their power generating license.

(La Crosse, WIS – August 12, 2020) – Specialty marine construction firm Nelosca Technologies, Inc. (Nelosca), announces its 4^th consecutive certification from international research and analytics organization Great Place to Work®.

95% of its employees consider Nelosca a great place to work, compared to just 59% of employees at a typical U.S.-based company. Nelosca’s high-ranking status among other companies is compounded this year by the changes in safety, travel, and essential work protocol brought about by the COVID-19 pandemic.

As a leader in inland waterway dredging, Nelosca Technologies (Nelosca) serves as a success story for hydraulically dredging and pumping sediments over long distances and changing elevations. The goal of most dredging projects is to maximize efficiency, which means maximizing the average percent solids in the pipeline. However, there is a fine balance between maximizing percent solids and surpassing critical velocity to transport dredge slurry. Therefore, a dredge operator must understand the importance of critical velocity and how it varies as the material in the dredge cut changes.

Critical velocity, in this case, is the minimum speed at which sediment and water (slurry) must be pumped to prevent the sediment from settling and subsequently plugging the dredge pipeline. Plugging the pipeline is the bane of any dredging operation and one of the few things that will set a dredge operator trembling in their boots. After all, if a pipeline gets plugged, the dredge must shut down, which means the entire project stops.

In industries like marine construction, the penalty for skipping or rushing through “simple” industrial rigging inspections or “ordinary” storage practices can be catastrophic for all of our equipment and tools, but most importantly for the people involved. 

For example, Nelosca uses endless and synthetic slings (straps or tie downs) to hoist and secure all kinds of materials: from piping and equipment, to dredges and other vessels. Reliable slings are critical to the work we do. We must ensure they are in excellent working condition before we use them and maintain them for our teammates who must safely use them next. Here are a few important questions we answer from curious customers and our own people.

As the sun on the dredging season in the Midwest inland areas began to set, operations were starting to heat up on the east coast for Nelosca Technologies (Nelosca). For a third straight year, Nelosca has had the opportunity to procure work in the milder maritime climate throughout New England during the winter months. These months are key for in-water work on the east coast as they provide opportunities to revitalize salt marshes, re-nourish beaches and restore navigation outside of the fish migration and spawning windows. Generally, this work has been undertaken in and near the coastal salt marshes adjacent to the smaller resort communities.

Nelosca Technologies, Inc. (Nelosca) recently won a contract with AECOM Energy and Construction (AECOM) for remediation work on LaGrange Lock and Dam on the Illinois River. The contract required us to partake in major gate and concrete rehab while supplying wireless internet access not only to our own Nelosca office trailers, but also to prime contractor AECOM and the United States Army Corps of Engineers (USACE) for the duration of the multi-year project.
