MARINE

Safely managing explosive, toxic, and environmentally damaging vapors from oil or petrochemicals in confined spaces is an ever present challenge for marine transportation.

NANOVAPOR’S PATENTED SYSTEM

TankSafe, when activated with NanoVapor’s patented Model ST-1000 delivery unit, reduces the amount of time spent reaching a safe LEL, increases the amount of time that VOCs stay suppressed, and produces no hazardous byproducts.

 

The delivery unit is portable and compact, weighs only 100 lbs (45 kg) and is designed to be intrinsically safe with an ATEX Zone II rating with no electrical or moving parts.  It has been specially engineered to use compressed air to activate and inject TankSafe in order to form an effective evaporative barrier at a molecular level.  This molecular suppression stops further fuel vapor formation and can be optionally applied further for long-lasting suppression.

For inland-marine and ocean-going vessels, the ongoing need for repairs, maintenance, or inspections often requires many hours or days to safely drain, purge, and gas free fuel oil or cargo tanks.  This can be particularly disruptive when unscheduled repairs are involved. In the marine transportation business, safety and time often work against each other as operators seek to improve overall efficiency by reducing the vessel downtime related to unscheduled and scheduled tank maintenance, repairs, and inspections.

 

WHY NANOVAPOR?

NanoVapor’s vapor suppression technology directly addresses these challenges this by greatly reducing the time needed to achieve and maintain safe vapor levels in both fuel oil and cargo tanks. Our systems are becoming available for marine applications, bringing the dramatic improvements in workplace health and safety made possible with nanotechnology. 

SAFER AND FASTER PURGING & GAS-FREEING

We address maintenance-related disruptions at the source by more quickly reducing tank LEL to safe levels—even when fuel or heel remains in the tank—avoiding altogether the need to drain, purge, and gas free tanks before starting hot work on nearby areas. 

VOC concentration is quickly suppressed to safe LEL levels that cannot ignite, while ambient oxygen levels are maintained for safe confined space entry.  Because our system eliminates flammability risk without removing oxygen, it is equivalent to purging and gas freeing at the same time.  

 

For tank inerting, conventional processes typically work by lowering the oxygen levels in the tank.  Unfortunately, this also introduces the risk of worker unconsciousness or death due to asphyxiation. Because our suppression inerting works without removing any oxygen, it provides a safer alternative for workers when tank inerting or entry is required.

 

PROVEN IN MARINE USE

We’ve adapted our suppression nanotechnology for marine use, resulting in a portable and simple to use delivery system and proprietary liquid suppressant engineered specifically for marine tanks.  The ST-1000 delivery unit can be powered using onboard compressed air, and has been successfully tested in actual marine use on both inland-marine and ocean-going vessels.  In degassing a 30,000-bbl barge, NanoVapor saved more than 50% of the time required to purge vapors to the target safe LEL level needed.  It worked even faster to purge and inert a heavy fuel oil tank on a bulk cargo vessel—safe LEL levels were quickly reached in less than 30 minutes without needing to drain any of the fuel oil or sludge that remained in the tank, and these safe levels were maintained for several hours while the nearby hot work was carried out. We can help you reach the same results.

 

NO RESIDUE OR CLEANUP

NanoVapor’s liquid suppressant leaves no detectable residue behind as only about 1 ounce of the engineered molecular suppressant is needed to gas free 100 cubic meters of tank volume.  In addition, all of our TankSafe suppressant is fully biodegradable, so there is no hazardous waste requiring any cleanup when the job is done.
