This invention discloses a new type of force bearing cylinder which does not use any piston and its related parts for pushing/pulling its stroke. The pistonless cylinder uses ordinary liquids, e.g., fresh water or seawater, as its hydraulic fluid. The pistonless cylinder can work as a hydraulic or pneumatic cylinder interchangeably without a need for any modification, and is basically maintenance free during its service life. As one example of its applications, the disclosed pistonless cylinder can be used for deepwater pile grippers in offshore platform installation.
