What is a Drill Ship?

Drill ships are special purpose ships which are used for drilling on the ocean beds at deep seas.

Such offshore drilling ships, relative to their operational peers have come to be regarded as a safe and sure option for extracting oil and gas at the sea.

This is mainly because of the easy transportability that these vessels offer vis-à-vis the semi-subs and other kinds of ships that are used to carry out drilling operations in the high seas.

Drill ships are inherently ships designed to provide optimum viability while on water, thus making it easy for the conglomerates to engage their services for better qualitative results in the overall scheme of drilling viability and functionality.

  • Drilling vessels can also be used as a analytical vessel to carry out sub-water researching operations in the high seas
  • The drilling equipment aboard these vessels can penetrate to really greater depths (anywhere over 600 metres to over 3,000 metres) and can be relocated in the high seas as the requirement necessitates
  • Likewise, the drilling equipments aboard the oil drilling vessels can also be employed to shoal areas to carry out the necessarily required maritime operations
  • In order to help them stabilise in the water, these vessels utilise equipments like GP systems and exceedingly strong support cables and ground tackles to keep them firmly positioned in the drilling area
 The construction of a drill ship involves a crane-like framework to hoist and lower the required drilling apparatuses from and into the water from a hatchway specifically constructed to pass through the vessel, into the water’s depths to aid the process. This feature of the offshore drilling ships makes them highly economical and conducive to the high seas drilling, in addition to the aforementioned aspects.

Drill Ships: Concept

The concept of a drillship is comparatively newer as compared to the currently existing crop of offshore drilling ships. However, in spite of their foundling nature in the high seas’ drilling operations, many shipping corporations have thoroughly embraced the idea of these oil drilling vessels as being a worthy peer to the current creed of drilling ships.

In terms of their initiation, drill ships were pioneered by American maritime engineers as a way of tackling the unpredictable maritime conditions in and around the country’s Pacific coastline in the mid-20th century. From their innovation till now, various technological developments have asserted the credibility of the drill ships. This has further emphasised its utility and functionality in the entirety of the international drilling sector.

Drillship: Further Expectations

There has been a huge spurt of growth in the demand for such drilling vessels. In the coming few years, it is expected that the demand for these ships will increase not just quantitatively but also qualitatively – in terms of their utilities and serviceable functionalities. If and when, such advancement comes to pass, it can be regarded as crossing a huge milestone in the international offshore drilling domain.
