<p>There are three types of offshore drilling rigs: Drillship, Semi-submersible, Jack-up rig.</p><p>As the generation of rig progressed, the operating water depth had deepened and consequently the ability of drilling equipment, redundancy and on-board capacity, had been enhanced.</p><p>The technological evolution of drilling rig made the hull and drilling equipment greater in size, which enabled deeper operation and that also led to considerable improvement in performance of major drilling equipment.</p><p>Looking back the progress of element technology in the past, we'll look into the latest specifications as of now and predict the rig of the future.</p>
