What is tender barge?

Tender vessels are typically flat bottom barges or semi-submersible, however in some instances, it a jackup- or semi-submersible rig or liftboat was used.

What is the difference between barge and rig?

A Submersible rig is a larger version of a posted barge and is capable of water depths of 18ft to 70ft. It has a floating drill unit that includes columns and pontoons that if flooded with water, will cause the pontoons to submerge to a depth that is predetermined.

What is semi tender rig?

Types of Tender Rigs They can be categorised into two types, i.e. the mono-hull tender-assist drilling rig (barge tender) and the semi-submersible tender-assist drilling rig (semi-tender). Both units carry the same equipment but the semi-tender is capable of operating in deeper waters and harsher environments.

How many types of rigs are there?

There are many types of offshore platforms used for oil and gas drilling and exploration. Some of these are fixed to the ocean floor and others are floating platforms or vessels.

What is a jackup drilling rig?

1. n. [Drilling] A self-contained combination drilling rig and floating barge, fitted with long support legs that can be raised or lowered independently of each other. The jackup, as it is known informally, is towed onto location with its legs up and the barge section floating on the water.

What is an 8th generation drillship?

The Deepwater Atlas and Deepwater Titan are the world’s first eighth-generation ultra-deepwater drillships and the only rigs to feature a 3,000,000 pound hook-load. These drillships are the most capable and highest specification rigs in the world and will include the first 20,000 psi well control system.

What is a 6th generation drillship?

The 6th generation deepwater drillships based on integrated design are entering service in 2011. Functional specifications have been incorporated into a newbuild drillship of an integrated class with improved capabilities, making operations more efficient and cost effective compared to non-integrated drillships.

What are the two types of rigs?

Rotary drilling rigs can be classified as land rigs and marine rigs.

What is a drilling rig called?

Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called augers.

What is RAB drilling?

What is meant by “RAB drilling”? As the name implies RAB, or Rotary Air Blast drilling, is an open-hole technique in which compressed air is injected down the drill pipe in order to recover the cuttings up the outside of the drill stem to the surface (Figure 3).

What are different types of drilling?

Here is an overview of the most common well drilling methods.

• Air Rotary Drilling Method.
• Bucket Auger Drilling Method.
• Cable Tool Drilling Method.
• Down the Hole Drilling Method.
• Reverse Circulation Drilling Method.
• Mud Rotary Drilling Method.

What are two types of drilling machines?

Types of Drilling Machines: Upright drilling machine. Automatic drilling machine. Multiple Spindle drilling machine. Deep hole drilling machine.

What is the principle of drilling?

Working Principle of Drilling Machine: When the power is given to the motor, the spindle rotates, and thereby the stepped pulley attached to it also rotates. On the other end, one more stepped pulley is attached and that is inverted to increase or decrease the speed of the rotational motion.

Why choose a tender rig?

Client satisfaction with the tender rig concept is a result of its sustainability, versatility and being a safe operation for operators. This has allowed us to not only perform development drilling activities but also production drilling, well completion, workovers as well as plug and abandonment for operators.

What is a tender barge in offshore drilling?

Drilling Tender Barge. A barge fitted with facilities to carry persons that is principally intended as support to an offshore drilling unit.

Who is the leading tender rig owner and operator in the world?

With approximately five decades of experience in tender assist drilling operations, our drilling segment is the world’s leading tender rig owner and operator. We have the world’s largest fleet of tender assist drilling rigs.

What is a tender assist drilling rig?

There are two different types of Tender Assist Drilling rigs (TADs), a tender rig and a semi-tender, both units carry the same equipment but the semi-tender is capable of operating in deeper waters and in much harsher environments. Typically, the TAD is stationed next to the platform and its drilling package is lifted onto the platform.
