Clean Landing — SBIR- STTR Success Story

A Mobile Cleaning, Recovery, and Recycling System Gets Naval Aircraft Carriers and Municipal Parking Lots into Shipshape

A Navy aircraft carrier idles in the middle of the ocean, readiness compromised by foreign object debris (FOD) across its flight deck. Debris and hard particles have built up from aircraft and ground-support activity. Even something as routine as moving planes from the hangar deck to the flight deck can spread debris or spill grease and jet fuel. Given that jet engines have powerful intakes that can suck up the debris, the risk of damage to aircraft engines becomes too significant to allow takeoffs and landings. Even a bit of spilled grease or fuel can be dangerous if aircraft slip into each other on the rolling deck of a carrier in high seas.

In order to get the carrier fully operational, the Navy calls on Triverus, a Palmer, Alaska-based small business that has produced advanced cleaning technology since 2001. Triverus ships their five-ton Mobile Cleaning Reclaim Recycle System (MCRRS, pronounced “McChris”) to the vessel overnight. MCRRS starts immediately cleaning the deck using water-jet technology, integrated air recovery, and waste-water recycling. Within a short time, the flight deck is spotless, and the ship certified as mission ready.

University of New Hampshire Stormwater Center invites Triverus to Durham, NH Campus


Before Triverus MCV Cleaning — Water Running Off         After Triverus MCV Cleaning — Water infiltrating


In the summer of 2019, the University of New Hampshire Stormwater Center invited Triverus to their campus in Durham, NH, to determine the effectiveness of the Triverus Municipal Cleaning Vehicle (MCV) in cleaning and restoring percolation rates to pervious surfaces.  UNH has several generations of pervious pavements, each installed when major changes or advancement in pavement design or installation occurred.  While each plot is still in use, predictably, percolation rates deteriorated over time.  By the summer of 2019, all their pervious paved surfaces were non-functional.  Over the period of a week, the MCV performed trial cleanings on five such plots. Every treated test plot showed restoration of acceptable percolation rates, even after up to 15 years of non-functionality.  UNHSC published a full review of the process and results of testing in the parking lot of their Alumni Center.  That study is attached here.

Palmer Company’s Cleaning Machine Deployed to Navy Flightdecks

PALMER, Alaska (KTUU) — Technology pioneered in an Anchorage garage and produced in Palmer is making its way onto Navy aircraft carriers.

Since the early 2000s, Triverus has been working on a machine that efficiently cleans flight decks and removes everything from grease and oil to debris.

“That can get sucked into jet engines and destroy planes awfully quickly, so what the Navy does right now is what’s called a FOD walk where they just send sailors out to one end of the carrier and they literally walk multiple times a day and just stare at the flight deck and pick things up,” Triverus manufacturing manager Nathan Green said.

The current methods used to clean flight decks inhibit the Navy’s ability to respond immediately when aircraft need to be deployed.

Triverus won a contract from the Navy to build 43 mobile recycling cleaning systems. Each machine costs $850,000.

It works by using pressurized water, magnets and a vacuum to remove debris from the flight deck. The debris is then filtered out and the water recycled.”

Palmer Business Sends First Military-grade Machine Overseas

“A Palmer manufacturing company is sending its first piece of military-grade machinery overseas.

The Triverus product is called MCRRS, short for Mobile Cleaning Recovery Recycle System. It’s basically a high-tech water vacuum designed to clean debris from flight decks on Navy aircraft carriers.

Each machine takes about one month to make and costs around $850,000.

The company has made a handful for the U.S. military. Now it’s filling its first order for the Italian navy.

CEO Hans Vogel said Triverus shows large-scale manufacturing is possible in Alaska.”

Aircraft Carrier Cleaning Machine


Triverus Ships First Production Aircraft  Carrier Cleaning Machine


Palmer manufacturing company Triverus LLC has completed its first of four MCCRS (Mobile Recovery Recycle System) for the US Navy. The machine uses patented technology to restore the necessary friction on flight deck surfaces and dramatically reduce pollution runoff into the ocean.

President/CEO Hans Vogel stated “Our team has worked with the Navy for 10 years in the R&D phase to meet all specifications and create a state of the art hard surface cleaning machine built right here in Palmer Alaska”

The Navy’s long-term plan is for Triverus to build up to 40 machines over the next 6 years, all of which will be made in Palmer according to Vogel.

Triverus also has a second manufacturing plant in Burlington, Vt. where they make the MCV (Municipal Cleaning Vehicle) a smaller machine tailored for storm water pollution prevention and high efficiency cleaning of parking facilities, airports and industrial applications. Minneapolis International Airport has five MCVs just for cleaning their parking garage.

Eric McCallum, an investor and partner in Triverus points out “ It’s a critical time to show Alaska can export technology and manufacturing, not just natural resources.

Aircraft Carrier Flight Decks

The Naval Surface Warfare center put out a call about 15 years ago for new technology to clean flight decks. The accumulation of fine debris on decks is a threat to aircraft. oil and other contaminants can make the surface too slippery for flight operations.
