6 FAQs about [Does replacing the drilling rig increase the project volume]

How is rig construction cost distributed?

Building a rig requires steel, labor, drilling, and other equipment. The manner in which cost is distributed across these categories determines the variation in construction cost by rig class, complexity, and time. Shipyard location plays a key role.

Does increasing water depth affect rig costs?

For drillships and semisubmersibles, increasing water depth is expected to have a less significant impact on costs, at least on a per foot basis. The increase in water depth associated with floating rigs is not on the scale of tens or hundreds of feet, but several thousand feet.

Why should you upgrade your rig?

An upgrade is a more significant investment that will likely increase the replacement cost, especially if the unit is subsequently classed into a higher category. Over the life of a rig, major components will be replaced due to normal wear and tear or due to technological advancements in drilling equipment.

Is there a relationship between jackup replacement costs and drill depth?

There was no significant relationship between replacement costs and jackup or semisubmersible delivery year nor was there a significant relationship between drill depth and cost for any rig type. Jackup replacement costs as a function of water depth. Replacement costs of semisubmersibles and drillships as a function of water depth.

How much does a new rig cost?

Average newbuild semis and drillships cost $553 and $672 million, respectively, relative to the existing fleet replacement values of $366 and $470 million. Differences in cost among rig types are due to greater water depth capability, cost escalation and rig specifications.

What factors affect rig costs?

The transport costs associated with supplies and raw materials also play a role in rig costs. For example, most of the steel used in jackup legs comes from the United States, European or Japanese steel mills and must be transported varying distances to the shipyard.
