Definitions of various offshore drilling rig types and generations

Many people ask us about the definitions of the various generations of offshore drilling rigs. The details below consist of the definition of offshore rig types and meaning of rig generations. This will help us get more understanding so when we hear about this drillship is 5th generation rig and we will know right away what it means.

Jack up

Self- elevating jack up are mobile, self-elevating drilling platforms that are equipped with moveable legs. Jack ups are towed to a drilling site by tug boats before the unit lowers its legs to the seabed and then jacks up the hull to elevate it above the sea level, after which drilling operations can begin. The units are used exclusively for shallow water exploration and production drilling.


A semi-submersible drilling rig is a floating drilling rig that is proficient of working in water depths ranging from shallow through to ultra-deepwater. Semi-submersibles use a number of pontoons that are submerged beneath the water line to float and remain stable in a single location. The deck is positioned above the water line and sits on top of a number of columns that join the hull to the submerged pontoons. Semi-submersibles offer an increased level of stability whilst drilling in comparison to drill ships and are thus preferred for drilling in harsh environment regions.

Drill ships

A drillship is a ship-shaped vessel that has been prepared for drilling operations. The unit can be utilized for drilling operations in mid water to ultra-deepwater areas and are generally preferred for exploration drilling as the assets are self-propelled. Drillships are kept on station using dynamic positioning systems.

Tender assist drilling units (Tender/Semi-Tender)

Tender assist drilling units (TADs) allow drilling operations to be carried out on a fixed platform without the need for a permanent drilling package on the platform. The TAD is stationed next to the platform and its drilling enclose is lifted onto the platform. The TAD remains in place in order to provide power and other services that support the drilling operation. There are two diverse types of TADs, a tender rig, and semi-tender, both units carry the same equipment but the semi-tender is capable of operating in deeper waters and harsher environments.

Types of oil drilling rigs

Getting down to the basics, there are several types of offshore oil rigs designed to work in a variety of locations, on certain kinds of wells, and differing environments:

  • Jack-ups are moveable drilling structures with bottom supports. Jack-ups have open-truss or columnar legs in support of their main deck or hull area.
  • Platforms cannot be moved like Jack-ups. They are immobile. Platforms are typically made from steel or cement and are used to drill new development wells.
  • Semisubmersibles drilling units, or Floaters, stay afloat offshore on giant pontoons or hollow columns. When overflowing with water, the pontoons or columns will partly submerge the unit to the desired Floaters are reliable in rough seas and most frequently used for drilling new wells.

Glass railings for decks

When deciding on a railing option for our deck or balcony, glass railings are the premier selection. From a practical standpoint, glass railings have a lot of advantages. They do not require regular maintenance, besides an occasional cleaning, and can last for years or even decades. However, there are two considerations that make glass railings particularly suited to raised decks and balconies.

First, glass railings are a very safe option for raised platforms. As glass does not wear out, deteriorate, or rot, sturdy glass railings can be expected to remain safe and dependable throughout their entire lifetime. Accidents and other mishaps are easily avoided. Second, glass railings can preserve views and scenery, allowing for uninterrupted scenic perspectives. This is one reason why glass is particularly good for balcony and deck railings.

Framed glass railings

Framed glass railings are the most common among glass railing systems, and they offer a combination of luxury and safety. Framed glass railings feature clear glass panels held in place by a frame. Frames can be made of metal, but if we want a maintenance-free option then aluminum is the best choice.

Framed glass railings can be secured to any surface, from wooden decks to concrete surfaces. Framed glass railing systems preserve views, ensuring sight lines and scenery. They are also commonly used to surround pools, where having a clear view is a matter of safety. Since they feature a frame and top rail, these railing systems are also great for stairs and raised platforms, allowing guests to place their hands along the top rail for support or a sense of security.

Frameless glass railings

When we have a stunning view that we want to make the most of, then frameless glass railings are our best bet. These railing systems feature glass panels without bordering frames, allowing for unimpeded views that are unparalleled by any other type of railing system. With frameless glass railings, there are no impediments to our view, making them a premier choice for balconies, decks, and rooftop terraces.

Look for manufacturers that can design customized frameless systems for our property. With a specialized frameless railing system, we can ensure safety on our property while getting the most out of our views. To read more about sliding glass shower screen in Singapore check here.
