2023年8月6日 · Jackup rig consists of a buoyant hull with retractable legs. The number of legs varies depending on design, three or four being the norm. Jackups are mobile, and vessels can tow them between locations with the legs fully extended above the hull.

Jack-up rigs are used to drill wells in shallow waters, typically less than 400 ft of water, and can be used to drill wells to a Total Depth (TD) of 30,000–35,000 ft. Due to their mobility, jack-up rigs can be used to drill exploration wells, appraisal wells, and development wells.

2018年8月5日 · A Jack Up is a type of offshore drilling rigs. It is made up of a hull, legs, and a lifting system and a jack up rig can be towed to the offshore site, and then lower its legs into the seabed to lift up the hull, providing a stable work deck which is strong enough to cope with the required environmental loads.

2021年4月26日 · Today, jack-up barges are the most common type of offshore platform and can be found across the world’s oceans- from the Gulf of Mexico to the Pacific Rim. How Do Jack Up Barges And Standalone Platforms Function? A jack-up barge is comprised of 4 main parts: 1. The buoyant and water-tight hull on which machinery and deck space is located, 2.

2023年12月15日 · A jack-up rig, also known as a self-elevating unit, is a type of mobile offshore drilling platform.

2015年6月25日 · The jackup-type mobile offshore drilling unit (MODU) has become the premier bottom-founded drilling unit, displacing submersibles and most platform units. The primary advantage of the jackup design is that it offers a steady and relatively motion-free platform in the drilling position and mobilizes relatively quickly and easily.

2021年6月18日 · Jacked-up rigs are floating drilling rigs with three or four movable legs which can elevate when the rig relocates from one location to another. Jack-up rigs are commonly used when drilling oil from deep-sea reservoirs.

2021年3月19日 · Jack-up drilling rigs are mobile offshore drilling units, or MODUs, pronounced "moe-dooz". Semi-submersibles and drillships handle deep water drilling of up to 12,000 feet of water, but MODUs excel in shallow and coastal areas of 400 feet or less.

2019年1月28日 · The jack up drilling rigs are designed in such a way that there are three poles that enable the oil rig base to either get hoisted up or stay afloat in the water. This is the main USP of a jack up platform.
