Understand Down Hole Items & How They’re Covered

Whether it’s mining, drilling or construction, there are some common claims that regularly come through from Yellow Cover customers; one of which involves down hole items.

Down hole items can be tricky to navigate when it comes to insurance, however, Yellow Cover’s National Strategic Underwriter for Mobile Plant and Equipment, Gary Woodhams has provided some guidance on the activities they are used for and the risks that are attached.

“Down hole items are specifically used for construction, production, and exploration activities, and are commonly attached to insured items such as Drill Rigs, Directional Drilling Rigs (HDD) or Drilling Platforms,” says Gary.

The most common down hole items used in these industries consist of:

  • Drill Heads such as Reamers, Pilot Heads, Diamond Cutting Heads and Hammers
  • Rods, Pipes and Casing
  • Collars and Sleeves
  • Floats and Stabilisers
  • Pumps, Mud Motors and Gyros


These items are utilised across a vast range of industries and applications. These include:

•             Core sampling

•             Seismic and environmental surveying

•             Water well drilling

•             Blasting

•             Oil and gas drilling

•             Piling, peering and foundations

•             Ventilations shafts

•             Directional drilling


Each item and application present a unique set of risks but when down hole items are connected and in operation (i.e. Drill String) these risks and exposures can become easily overlooked.

“Loss of equipment by detaching or falling down hole is one of the most common claims we encounter and although Down Hole Cover may have been selected on the policy, if no down hole items are noted on the schedule, it’s extremely difficult to pay a claim for items that are not insured,” notes Gary.

“When accumulated the total sum insured of these down hole items can be quite expensive, so we must have the details on the policy schedule, not just for down hole events but for other events such as theft, rollover, and malicious damage, which could leave you out of pocket.”


Standard policy wordings will automatically exclude cover for down hole events, i.e.

Yellow Cover will not cover a drill shaft/bit for loss or damage to the drill shaft or bit of any drilling rig or machine, whilst in use drilling:

a) Into or below ground; or

b) Below the surface level

However, this cover can be reinstated if requested at policy inception, therefore  if you are going to be using down hole items and wish to have them covered as part of your insured property, the items need to be endorsed and noted in the insurance schedule.

Yellow Cover’s standard Down Hole Endorsement provides an automatic exposure offering of $50,000, noting that this standard offering can be increased to suit all exposures on request.

“By requesting Down Hole Cover, we are able to capture an exposure limit that is suitable to the application and ensuring you are covered should an incident occur,” adds Gary.

If there is one takeout from this blog, please remember: if the items have not been disclosed, issues may arise in determining what the loss actually is, making it difficult for both you and the insured when making a claim.

No matter the scale of your project, Yellow Cover’s tailored coverage is designed to keep your equipment protected.
