Latest Patents

One of Lacey's notable inventions is the "Ram-type tensioner assembly having integral hydraulic fluid accumulator." This advanced tensioner assembly is engineered to deliver tensile force from a floating vessel to the blowout preventer stack located on the sea floor. By compensating for vessel motion caused by wave action and heave, this invention maintains a variable tension to the riser string, minimizing the risk of compression and potential failure. The assembly features a cylinder, a stop tube, and a ram that works in tandem with a gas transfer tube, creating a pressurized air-over-hydraulic fluid system.

Another significant patent is the "Portable drill string compensator." This design incorporates a closed system with a hydraulic fluid accumulator and air pressure vessels, allowing for effective tensioning support of a drill string. By facilitating a secure connection between the drilling vessel and the drill string during ocean level fluctuations, her design ensures operational continuity even amid challenging marine conditions. The accumulator’s unique structure and two-port design enhance fluid communication, promoting overall system efficiency.
