Short answer
Contractors equipment coverage is inland marine insurance for your own tools and mobile equipment, the gear that moves from job to job: welders, pumps, generators, light towers, compressors, and similar equipment. It pays to repair or replace that equipment after a covered loss. Your general liability policy will not, because it excludes property you own.
- It is usually written on nonfiled forms, so wording varies more between insurers than on GL or auto. Read the covered causes of loss, exclusions, and how losses are valued.
- Under knock-for-knock MSAs, damage to your own surface equipment is usually your risk. The IADC model contract has the contractor assume its own surface equipment, while the operator takes in-hole equipment and damage from H2S and other corrosive elements.
What it covers and why your GL and auto do not
IRMI defines an equipment floater as "property insurance covering equipment that is often moved from place to place," and classifies it as inland marine. Inland marine forms often cover property wherever it is, which is why they are called floaters.
Your other policies leave this gap for different reasons:
- General liability covers your liability to others. Exclusion j.(1) in the ISO form removes damage to property you own, rent, or occupy.
- Mobile equipment liability is covered in the GL, but IRMI notes that "physical damage coverage is usually provided by an 'equipment floater.'"
- Business auto covers vehicles. The ISO GL definition of mobile equipment says self-propelled vehicles with permanently attached air compressors, pumps, generators, and "well servicing equipment" are treated as autos, not mobile equipment.
That last point matters for oilfield fleets. A pump truck or rig-up truck is an auto for liability purposes. Make sure every unit, and the equipment mounted on it, is on either the auto schedule or the equipment schedule, and not missing from both.
How the MSA allocates your equipment
Most oilfield MSAs say who bears the loss of each side's equipment. The IADC model U.S. daywork contract is a useful reference:
| Subparagraph | Equipment | Model allocation |
|---|---|---|
| 14.3 | Contractor’s surface equipment | Contractor, regardless of when or how the loss occurs, with exceptions |
| 14.4 | Contractor’s and subcontractors’ in-hole equipment | Operator, reimbursed at an agreed value |
| 14.5 | Contractor equipment damaged by H2S, CO2, or other corrosive elements in the drilling fluid | Operator, including repair or decontamination |
| 14.6 | Operator’s equipment, including casing, tubing, and wellhead | Operator |
Waivers reach this policy too
If your MSA requires a waiver of subrogation on all policies, that includes your equipment coverage. Otherwise your insurer may pay your loss and then pursue the operator, which the MSA says it cannot do.
Features to check
IRMI notes contractors equipment coverage is a nonfiled line in many states, meaning insurers are not required to file forms and rates for approval, and coverage is often written case by case. That makes these questions worth asking every time:
- Scheduled or blanket. Is each item listed with a value, or is there a blanket limit for unscheduled tools? What is the per-item maximum on unscheduled items?
- Valuation. Are losses paid at actual cash value or replacement cost?
- Rented and leased equipment. Does the policy cover equipment you rent from others? Rental agreements often make you responsible for it. See the care, custody, or control exclusion.
- Below ground. Does the form exclude equipment while downhole or underground? If so, does your MSA put that risk on the operator?
- Cranes and booms. IRMI notes floaters normally exclude booms over a specified length while in operation unless damage is caused by a named peril; boom coverage is added by endorsement.
- Breakdown. Is mechanical or electrical breakdown covered, or only external causes like fire, theft, collision, or overturn?
- Employee tools. Are tools your hands own covered while on your job?
Keep the schedule current
Equipment coverage is only as good as the list behind it. Keep a schedule with make, model, serial number, year, and value, and update it when you buy, sell, or move equipment between companies. A unit bought mid-year and never added is a common way to end up uninsured on the one piece that burns.

Common questions
Is contractors equipment coverage required by MSAs?
Usually it is your choice, because loss of your own equipment is typically your risk under the MSA. But the MSA may require a waiver of subrogation on it, and a loss that stops work can hurt more than the equipment itself.
Does my auto policy cover a welder bolted to my truck?
It depends on how the truck and equipment are scheduled and what your auto physical damage coverage includes. Ask your agent to confirm in writing which policy covers mounted equipment.
Are my tools covered if they are stolen from a lease overnight?
Theft is a common covered cause, but some forms limit theft from unattended vehicles or job sites. Read the theft conditions on your form.
What is the difference between an equipment floater and a builders risk?
An equipment floater covers equipment you use to do the work. Builders risk and installation floaters cover property being built or installed. IRMI groups all of them under inland marine.
