  • Publication number: 20250340283
    Abstract: STAXLINK™ is a duct system and method for conveying exhaust gas from an exhaust pipe of an emissions source to a purification unit during an Emissions Reduction as a Service (ERaaS) operation. Example emissions sources include oceangoing vessels and buildings structures. The duct is temporarily installed onto the emissions source without a crane. The duct is supported by the emissions source itself for the duration of the ERaaS operation.

  • Publication number: 20240367762
    Abstract: A novel emissions control watercraft (STAXcraft) solving a long-felt but unsolved need regarding disadvantages associated with prior-art emissions servicing watercraft, the disadvantages selected from the group, but not limited to, the use of tugboats, securing or mooring servicing watercraft to a serviced vessel, additional expenses and time-delays and inefficiencies of land-based approaches, increased toxic emissions, increased greenhouse gases (GHG) emissions, danger from falling cargo, tanker safety, alongside mooring in narrow channels preventing other OGV's to pass safely, and cargo tank emissions.
