Neoteric in the News: Munitions Detection Using Hovercraft

From mainstream media across the world, to highly specialized publications, Neoteric hovercraft and our customers are continuously newsworthy. The following article, published in the September 2014 edition of the Environmental & Engineering Geophysical Society's magazine FastTIMES, reviews yet another use for the Neoteric HoverTrek™ - the detection of unexploded ordnance over shallow coral reefs in the Caribbean Sea ...
Tetra Tech MEC/UXO Detection System Deploys via Neoteric Hovercraft

Tetra Tech, Inc., in collaboration with Neoteric Hovercraft, Inc., has produced a new environmentally-sensitive munitions detection system capable of accessing shallow areas where no other watercraft is able to travel and where sensitive habitat is only inches beneath the water’s surface. Tetra Tech’s in-house developed TEMA (Towed Electromagnetic Array) attaches to the company’s customized Neoteric hovercraft to permit MEC/UXO detection in areas previously accessible only by more expensive, less sensitive aircraft-based systems.
In an early prototype developmental model Neoteric hovercraft, the TEMA system
is tested and evaluated to determine the optimal pivoting and pushing system.
Richard Funk, Senior Geophysicist with Tetra Tech’s Marine Mapping Group, describes the TEMA’s unique features: “Unlike a magnetometer, the TEMA is an active sensor that can detect all metals, ferrous and non-ferrous. Its detectors are focused, so they’re not affected by nearby metal structures such as piers, bulkheads and bridges. Data from all devices – multiple high-power EM sensors, altimeters, positioning sensors and video/still cameras – is recorded in real time. The 3-meter swath coverage and the use of high-power EM units increases survey power, with lower operational costs and better detection capabilities.”

Tetra Tech has researched the use of hovercraft for MEC/UXO survey for many years, particularly for use in difficult areas for data collection, such as shorelines and surf zones. “Our goal is to push it to the next level so we can go where other people can’t go,” Funk says, “A hovercraft takes you places you can’t go with conventional craft, places that are too shallow for a boat, places you can’t walk.”

Tetra Tech selected Neoteric to manufacture their hovercraft because “Neoteric’s HoverTrek™ outmaneuvers other hovercraft on the market, and our projects demand that increased control,” said Funk. “Additionally, Neoteric has decades of experience custom-manufacturing their hovercraft to client specifications, and we were impressed by the company’s mandate that repeated testing be performed throughout the customization of our hovercraft.” The craft’s customizations include mounting points for the TEMA sensor array, mounts for the electronics modules, mounts for the pilot’s display and data collectors’ displays, a table for data collectors, TEMA battery mounts, GPS antenna mounts, and a bimini top.
Tetra Tech’s fully customized Neoteric HoverTrek™ is prepared for its final over-water testing.
The unusual maneuverability of the Neoteric hovercraft is attained through a patented fly-by-wire reverse thrust system, which makes it the only hovercraft on the market with effective brakes. As Neoteric President Chris Fitzgerald explains, “Our reverse thrust system surpasses jet aircraft in efficiency; while most aircraft deliver an average of 18 percent thrust in reverse, the HoverTrek™ delivers 60 percent. Unlike other hovercraft, the HoverTrek™ can fly backward, spin, and hover over ice and on swift water.”

Tetra Tech will deploy its new hovercraft-based munitions detection system in early 2015 to conduct Phase 2 of an ongoing MEC/UXO remedial investigation and feasibility study at a Defense Environmental Restoration Program (DERP) for Formerly Used Defense sites (FUDS) area in the Caribbean. The site was an impact range for aerial bombs and rockets, missiles, mortars and naval projectiles from 1903 until 1975.

The entire site comprises 1,030 acres; the area to be surveyed with the TEMA-equipped Neoteric hovercraft is more than 200 acres of shallow coral reefs with listed and protected corals. This area was originally excluded from the survey due to the potential for damaging the coral. By using the Neoteric HoverTrek™, which hovers nine inches above the surface of the water, Tetra Tech can now complete the survey with confidence that the coral reefs are in no danger of harm.

The pairing of the TEMA system with the Neoteric hovercraft’s low environmental footprint - less than 1/30th that of a human foot – is an excellent example of how the perfect vehicle for the job can also be the perfect vehicle for the environment, allowing personnel to work safely and efficiently while protecting sensitive habitat.

Hovercraft in Minnesota Mining Operations

When you think of vehicles used in mining operations, a hovercraft may not come to mind … unless you have the foresight of David Olson. Olson’s company, D & T Landscaping, Inc., is under contract to seed and reforest, as well as to manage environmental hazards such as blowing dust, at a major taconite mining region on the Mesabi Iron Range in Minnesota.

Some background: Taconite is an iron-bearing sedimentary rock, a low-grade iron ore. When high-grade natural iron ore was plentiful, taconite was considered a waste rock, but the industry recognized its value as the supply of natural ore diminished. After years of research, scientists and engineers at the University of Minnesota developed a way to extract the iron ore from taconite, which is mined in opencut mines, then crushed, processed into small pellets and shipped to steel mills.

David Olson explains what happens during the process: “As the rock is crushed, the residue is mixed with water and pumped into tailings ponds to dry out. As that surface dries, the dust is picked up by the wind and can be blown into nearby towns. Mining companies are strictly mandated by state and federal regulations to control environmental issues such as dust.

But how can hovercraft help solve this problem? “We need something different. We use tractors and piston bullies, but they don’t work well in a soft environment. The surface is like quicksand; it does build a crust as it starts to dry, but you can’t stand or walk on it. Our situation is basically mud,” Olson says. “We’re looking into using a liquid dust suppression agent on the tailings, and we need to be able to get out to places where our current technology doesn’t take us. I want to see if hovercraft can help us facilitate that process. ”

Olson’s first step was to take a one-day standard pilot training course at Hovercraft Training Centers in order to familiarize himself with hovercraft technology and to evaluate the capabilities of the Neoteric range of light hovercraft ...
At the controls, David Olson learns to fly a Neoteric Hovercraft at HTC,
with Senior Instructor Chris Fitzgerald providing directions as needed.
After his day at Neoteric and Hovercraft Training Centers, Olson was convinced that hovercraft would do the job. “Even if we can cover 80% of what’s not being covered today, that’s a significant improvement,” he said. And he found it to be an enjoyable experience, adding, “It’s pretty exhilarating. It’s fun! I could see myself personally wanting one. And it’s much more stable than I anticipated.”

Olson was reasonably sure after his training that hovercraft could help spread the surface sealant agent that he was considering. His next step was to arrange an on-site evaluation at a Minnesota mining site to see how the hovercraft would handle the variable, soft and sticky surface of the tailings ponds ...

The evaluation looked promising and Olson believed that hovercraft would give him the opportunity to expand the surfaces he could reach. So, working with Neoteric, a set of requirements for application rate and acreage covered per hour were developed, along with various scenarios to be evaluated for the purpose of optimizing the spraying operation. An application rate of 30 gallons per minute was deemed necessary in order to cover the vast area with which Olson must deal.

This resulted in an order for two hovercraft each capable of carrying 100 gallons of the dust suppression agent/water mixture, fuel, a pilot and a lightweight spraying system ...

Eric Whalin during the manufacturer and installation of the spraying system.

Since all off-the-shelf commercial spraying systems were too heavy, Neoteric fabricated
the special lightweight tanks used to transport and store 100 gallons of dust suppression agent
aboard the D & T Landscaping hovercraft. 

Neoteric designed, built and tested two spraying systems, one for each D & T hovercraft, in record time because the weather was rapidly deteriorating in northern Minnesota. And the entire pumping system and tank weighed just 80 pounds!

These two videos of Chris Fitzgerald testing one of the completed craft illustrates the high degree of control the Neoteric hovercraft's reverse thrust system will give D & T Landscaping ...



Finally, Chris Fitzgerald and HTC flight instructor Steve Stafford delivered the two hovercraft to Olson in Minnesota and conducted flight training for D & T Landscaping personnel at the actual taconite mining site, with the crafts’ dust suppression systems in full operation.

D & T Landscaping personnel enjoyed their flight training and were impressed with how
the hovercraft will expand their capabilities. With Neoteric President Chris Fitzgerald (left)

The Neoteric hovercraft utilized by D & T Landscaping will increase the reach and speed of their dust suppression efforts. Hovercraft expand access to areas on the mining site that are difficult for other vehicles to reach, and they operate less expensively than other vehicles. Hovercraft also move much faster than tractors or piston bullies, which can become stuck in the mud.

In addition, the hovercraft are controlled internally by D & T Landscaping without the need to rely on outside contractors to provide, for example, helicopter services. Helicopters have been used in the past by D & T to attempt to manage the blowing dust problem.

The use of hovercraft for dust suppression in taconite and other similar mining operations can protect companies from legal actions and expensive dust cleanup in nearby regions. Make no mistake, this industry is vital to Minnesota, which is the largest producer of taconite and iron ore in the United States. During World War II, one-fourth of all the steel used in the United States came from this area and Minnesota’s Iron Range currently contributes more than $1.8 billion to the state’s economy. Taconite saved Minnesota’s iron ore mining industry and is the largest employer in the central iron range region. And reports suggest that taconite reserves exist in this area to last at least the next 100 years.

Neoteric Hovercraft in Gold Mining and Coal Mining

The Minnesota project is not the first time Neoteric hovercraft have played an important role in the mining industry. In the past and present, our craft have been employed in similar mining operations, such as accessing tailings ponds at cyanide gold leaching mines in the Dominican Republic, Mexico, South  Carolina and Montana.

Neoteric craft are also utilized in coal mining operations and at coal fired power plants, which often slurry coal or residual ash for the purpose of transportation to storage or waste slurry ponds. The hovercraft are used to safely traverse the ponds’ surface for rescue of personnel and wildlife, for surveying, to check chemical levels and to transport work crews needed to position infill piping ...

Neoteric hovercraft have also proved to be a vital tool where similar conditions
and requirements exist, such as in dredging operations in Chesapeake Bay, Maryland 
(shown here) and in rebuilding barrier islands in Mississippi. See more photos ...

The Increasing Importance of Hovercraft

Maritime Reporter and Marine News magazines recently published an article emphasizing the need for hovercraft to play a growing role in maritime operations, due to their singular ability to travel where no other vehicle can go. Here are a few excerpts:

Extreme Applications Demand Specialist Small Craft

With 90% of world trade transported by sea then passing through ports and waterways, no amount of technology will replace the requirement for multiple small fast craft and skilled operators.

Mobility plus the ability to operate in shallow areas are critical capabilities for small craft. 

Rising Up: Hovercraft

Small hovercraft have a growing role to play in search and rescue, commercial and military operations around the world. Hovercraft can be a practical proposition for operations in areas inaccessible to other vehicles including frozen water, mud flats, intertidal areas, shallow rivers and flooded inland areas. Perceived to be environmentally sound, as they don’t exhaust into the water, create no wash and do not disturb the sea bed, they are also economical and do not endanger marine animals as there is no propeller in the water. 


Enjoy a few photos of Neoteric hovercraft in action around the world
that confirm these capabilities ...

Neoteric commercial hovercraft utilized in Kuwait intertidal zone
Neoteric hovercraft were used on Kuwait's intertidal zone to survey the environmental damage inflicted by the 1991 Persian Gulf War oil fires. The hovercraft was the only vehicle capable of operating on the thick mud.

Wilkes-Barre Fire Department Neoteric rescue hovercraft
The Wilkes-Barre Fire Department’s Neoteric rescue hovercraft soars over broken ice on the Susquehanna River in Pennsylvania during ice rescue practice. The craft’s 9-inch deep air cushion and patented reverse thrust enables it to safely maneuver over jagged, broken, snow-covered ice floes.

Neoteric rescue hovercraft deployed in 2014 Washington mudslide
Snohomish County Fire District 19’s rescue hovercraft were deployed from the initial alarm at the massive Oso, Washington mudslide. First responder Trent Nunemaker said, “Our hovercraft can navigate through floating debris and logs, so we’re able to cross the flooded valley and access the debris field. These Neoteric craft are able to quickly and safely access almost any environment.”

Finally, you’ve probably seen the viral video of the Neoteric craft rescuing three exhausted deer, stranded on the ice for days on Albert Lea Lake in Minnesota - but it's worth watching again! 

As the media reported, "Hovercraft are kind of a genius idea here ... Boats and jet skis are pretty useless on ice and snowmobiles fall through ice if it won't hold their weight. Hovercraft can fly over any surface, so they save many lives. If you fall through the ice, or get sucked into mud or quicksand, better hope someone locally has a hovercraft handy."
