The oil and gas industry, as a whole, is considered to be a stream of activities from the upstream activities (getting natural resources from the ground) to the downstream activities (purifying Ocean tow of jackup drilling units book for use as fuel or plastic and other things).Offshore drilling is very much an upstream activity.
On the barge's deck are steel posts that extend above the water line. A drilling platform rests on top of the steel posts. These rigs are typically used in areas with calm water.
A jackup is a rig that sits on top of a floating barge. A ship tows the barge to the drilling site. Once positioned, the jackup can extend legs down to the sea floor. An oil platform, offshore platform, or offshore drilling rig is a large structure with facilities for well drilling to explore, extract, store, and process petroleum and natural gas which lies in rock formations beneath the seabed.
Many oil platforms will also contain facilities to accommodate their workforce. Most commonly, oil platforms engage in activities on the continental shelf, though.
Ocean Tow of Jackup Drilling Units: Inspection and Certification of Floating Detention Facilities: Initial and Subsequent Inspection of Existing, Uncertificated Offshore Supply Vessels, Including Lifeboats: Determination of Cold Water Areas: Fire Drills and On-Board Training: As technology developed, and drilling moved into deeper water, explorers designed platforms from concrete and/or steel, with legs anchored securely into the seabed.
This photo shows a steel jacket ready to tow out to deepwater. Once the jacket is set into the. The first truly offshore MODU was the Mr. Charlie, designed and constructed from scratch by Ocean Drilling and Exploration Co. (ODECO) headed by its inventor and president, "Doc" Alden J.
Charlie (Fig. ) was truly a purpose-built submersible barge built specifically to float on its lower hull to location and, in a sequence of flooding the stern down, ended up resting on the. safety and integrity of jack-ups deployed in the marine renewable energy industry.
Nature of the guidelines This guidance is intended to be relevant to all organisations contributing to the operation of jack-ups, but it is particularly relevant to jack-up owners’/operators’File Size: 2MB.
Offshore drilling is a mechanical process where a wellbore is drilled below the seabed. It is typically carried out in order to explore for and subsequently extract petroleum which lies in rock formations beneath the seabed.
Most commonly, the term is used to describe drilling activities on the continental shelf, though the term can also be applied to drilling in lakes, inshore waters and. A concrete island drilling system (CIDS) features a reinforced concrete caisson. 23 Drilling equipment is placed on the deck of a barge to drill in the shallow waters of bays and estuaries.

Determination of Cold Water Areas Fire Drills and On-Board Training. Generally, the only alternative to a shell pad is a shallow water jack-up or a submersible rig. And in some instances, it is impractical to tow these mobile rigs to the location because of the necessary dredging.
A possible solution to this problem, devised by Chain Jacks, Inc., is a jack-up. Drilling terminology deals with major rig components, processes and equipment required to drill and case a well.
Definitions in this module range from abnormal pressure to penetration rate and zip collars, and many are augmented by color photographs or high-quality definitions have been reviewed by technical experts in the field of drilling.

Alexander Kielland platform --fatigue failure of one brace, overload in 5. A Wet Ocean Tow is defined as an afloat move lasting more than hours which does not satisfy the requirements of an Extended Field Tow.
In this condition, the Jack Up Unit is afloat on its own hull with its legs raised as with a Field Tow, but, for many Units, additional precautions must be made.
A drill ship is a vessel with a drilling rig and station-keeping equipment for drilling oil fields in deepwater. Drill ships have a larger payload capacity than semi-submersible drilling vessels, but face shortcomings in terms of their motion characteristics.
Figure illustrates a drill ship. A jackup rig is a mobile, self-elevating drilling platform equipped with legs that are lowered to the ocean floor until a foundation is established for support, at which point the hull is raised. Where oil rigs go to die. Ina rig called Ocean Viking had been idly and unhopefully prospecting in this region, when a worker named Stale Salvensen, down on .This results in a bifurcation of the drilling fleet for both the jackup and floater rig classes and is evidenced by the higher specification drilling rigs generally operating at higher overall.
