Oceans have a vast abundance of fossil fuels that still needs to be tracked. With the onshore reserves depleting at a faster rate by constant scooping and drilling operations, the oil & gas companies have increased their operations in the offshore to meet the global demand of crude oil. Offshore drilling and platform development have gratified billions of tones of hydrocarbons to the market over time. The important factor that needs to be considered in offshore drilling operations is that these operations are challenging and require a lot of revenue investment.

The offshore operations start with locating the oil and gas reservoirs by deploying survey vessels for seismic surveys. Once the potential site is identified, oil companies are called for auctions and are asked to submit their bids for a particular block. After the block is acquired, the oil companies employ the offshore drilling units for subsequent drilling or workover operations. The offshore drilling unit is a large structural vessel capable of engaging in drilling and well intervention operations for the exploration for or exploitation of resources beneath the seabed.

There are several types of offshore drilling units available in the market. The reason for so many types, sizes and capabilities of offshore units involves the different technical, economic, government and safety aspects that are required to be fulfilled in a specific drilling program. A single unit cannot serve all the requirements; hence the oil companies need to choose the unit wisely.

  • Fixed Platform Unit: The rig unit sits on a fixed structure previously installed at a well location. The structure may be a fixed jacketed platform, spar, tension leg platform (TLP), or gravity structure; whatever it is, the rig sits atop it. Fixed platforms may have as few as 3 or more than 50 well conductors. There are generally 3 types of fixed platform rigs: conventional standard platform rigs, modular fixed platform rigs and self erecting-self loading highly modularized rigs.
  • Tender Assist Drilling Units: They are used less commonly now but are suitable for certain situations like drilling new well from an aging platform near shore. The TAD is positioned next to the platform and the drilling package is lifted onto the platform.
  • Drilling Barges: They are generally employed for shallow water drilling in calm water conditions. Drilling equipment is placed on to the barges’ decks and towed to the site by tugs. Anchors hold the units at the drilling site.
  • Jackups: They are mobile, self-elevating drilling units equipped with moveable legs. The unit is towed to a drilling site by tug boats followed by lowering its legs to the seabed and then jacks up the hull to elevate it above the sea level. These units are generally used for shallow water exploration and drilling. The two types of jackup units are independent leg type jackup and mat type jackup.
  • Semi-Submersible Units: A semi-submersible drilling rig is a floating drilling rig capable of working in ultra-deepwater depths. The unit uses a number of pontoons that sunk beneath the water line to float and remain stable in a single location. Semi-submersibles offer an increased stability as compared to other units and are mostly preferred.
  • Drill Ships: It is a ship shaped unit that has easy mobility proving an advantage over semi-submersible units. They aim at providing complete offshore drilling solutions as they are equipped with advanced technologies.

The applications, advantages and limitation of each type of unit have been discussed in detail in our exclusive report. The global offshore drilling unit market value is estimated to be 71879.6 million USD in 2016 growing at an estimated CAGR of XX % in the forecast period of 2018-2028.

The increasing global energy demand with depleting onshore resources are the driving factors of the market. Also, the easy availability of water that is required in large amounts during drilling operations has also encouraged the companies to drill offshore. The key restraints to the growing market involve the environmental concerns and strict policies in the oceans like oil spills, damage to fauna, etc. The opportunities in the offshore drilling unit market lies in the drilling operations in much deeper depths, increasing stability in harsh environmental conditions, overall cost effectiveness, etc.

The profiles and the comprehensive operational study of various key players in the offshore drilling unit market like Transocean Ltd. (Switzerland), Nabors Industries Ltd. (Bermuda), Ensco Plc. (U.K.), Seadrill Ltd. (U.K.), etc. have been well analysed and included in the report.
