The Coast Guard is revising existing safety regulations for facility and vessel vapor control systems (VCSs) to promote maritime safety and marine environmental protection. The revisions promote safe VCS operation in an expanded range of activities now subject to current Federal and State environmental requirements, reflect industry advances in VCS technology, and codify the standards for the design and operation of a VCS at tank barge cleaning facilities. They increase operational safety by regulating the design, installation, and use of VCSs, but they do not require anyone to install or use VCSs.

Envent attends the CTAC Committee meeting in Washington DC on May 7 & 8.  The end result of this meeting was the attached Policy Letter from the United States Coast Guard on the Safe Operation of Mobile Vapor Control Systems.  The USCG provided the attached Policy Letter clarifying that CFR 154 safety equipment,  shutdowns and controls requirements will not be replaced by a man standing nearby ready to push the mushroom as some competitors seem to have been hawking.  Customers now have the piece of mind and clear guidance that the USCG wants things done safely.  Envent will provide that safety system in our prepacked Envent EMECS and Envent Dock Safety Unit (DSU).

The 3 Most Common Areas of Concern your Provider Should Address before You Sign on the Dotted Line

We at Envent have been in the business of mobile vapor and water treatment for over 20 years.  We are fully aware that degassing jobs at refineries and petrochemical plants, two of the most technically sophisticated places on the planet, require a zero tolerance policy for mistakes. It’s the way it should be, and there is no substitute for just plain doing things “the right way.”  Degassing and vapor control is too important to be left in the hands of an inexperienced operator, so we thought we would let you in on the three most common concerns we address from our customers so you can ensure that you, too, are in more than capable hands when you decide on who to hire for the job.

As professionals in the industry, we are all aware of the science behind those ‘no cell phone’ warning signs stationed so predominately, almost like guarding sentinels, at filling stations across the country. We know that the very clear and well positioned regulatory dictates are not just the product derived from an overzealous gas attendant’s aversion to our technology obsessed society but are actually a warning to those not privy to the rules of static electricity and flammable vapors that their most beloved and coveted mobile device could be the catalyst to igniting said vapors and act as an enabler to extremely hazardous conditions. This everyday occurrence of being reminded to not use our mobile devices while filling our gas tanks is definitely worth remembering if you are using vacuum trucks to control vapors when tank degassing at factories and other large facilities. The technique of grounding and bonding during a degassing operation is a practice that can safely control the accumulated static charges and prevent workplace accidents. We at Envent Corporation keep a strict adherence to workplace safety and employ preemptive tactics to avoiding hazardous situations when grounding and bonding. We have included a few of our approaches for your reference.

Welcome to the latest, greatest addition to the Envent fleet of industry-leading equipment: the EMECS 42 Marine Vapor Control System, better known as the MVCS.

Envent designs and builds its equipment to set new standards for the industry, and the MVCS is no exception. Our MVCS mobile system is the first in the nation to be certified by the United States Coast Guard for gasoline loading.  (It fully complies with all sections of 33 CFR 154 Subpart E.)

Here’s the lowdown on our MVCS.  The machine can support a transfer rate of 4,000 barrels per hour, and its redundant safety systems are prepared to handle a wide range of “unexpected” occurrences, including barge overflow alarms, enrichment system, oxygen analyzers, pressure monitoring, and relief valves.  The system includes an interlock that shuts down the loading pumps in the event of any unexpected condition at the MVCS or the vessel.
