Latest Patents

John J Macan holds a patent for a "Sea-floor shoring cellar and method of installing same." This invention provides an implantable sea-floor shoring cellar designed to house drilling equipment, such as a blowout preventer stack, partially below the sea floor. This design allows for oil well drilling by drill ships in shallow water areas where the distance between the sea floor and the drill ship is insufficient for normal positioning of the blowout preventer stack. The shoring cellar features a substantially cylindrical retainer wall assembly with an annular air ejector assembly, including ejector nozzles mounted within the retainer wall assembly adjacent to a lower opening. Additionally, a plurality of discharge tubes are mounted over the ejector nozzles to remove earth loosened from the sea floor during the cutting of an opening below the retainer wall assembly, enabling the assembly to be lowered without interference into place.
