What is Tank Erection and Repair?
Tank erection and repair insurance helps protect companies that build, install, maintain or repair storage tanks from liability and property exposures that can arise on the job. Coverage is designed for operations that work with large metal, fiberglass, or concrete tanks used for water, fuel, chemicals, or agricultural storage. Typical insurance considerations include commercial general liability, equipment coverage, environmental liability, and workers' compensation exposures.
Who needs it
Contractors, tank manufacturers, installation crews, maintenance providers, and facility operators commonly seek this coverage. If your work includes on-site assembly, welding, coating, or connecting fuel systems you should evaluate your liability and pollution risks. Installers and service companies often compare specialized offerings like Tank Installation and Service (UST/AST) Insurance when selecting policies.
What it typically covers
Policies for tank erection and repair usually bundle several elements to address common exposures:
- Commercial general liability for third‑party injury or property damage at the job site
- Contractors’ equipment or inland marine coverage for tools, cranes, and hoists
- Pollution or environmental liability for accidental releases or soil contamination
- Workers’ compensation for employee injuries — often coordinated with a trade‑specific plan such as Tank Building Workers Compensation
- Commercial auto coverage when company vehicles transport materials or crews
These coverages are often offered as packaged solutions or as endorsements added to broader commercial liability policies.
Common exclusions or limitations
Policies commonly exclude deliberate acts, wear and tear, latent defects in materials, and pre‑existing contamination. Some insurers limit coverage for certain pollutants or for tanks that store high‑hazard substances unless additional environmental endorsements are purchased. Specialized operations such as tank removal and disposal may need tailored policies; see examples like Tank Removal Insurance for those unique exposures.
Factors that influence cost
Premiums depend on several underwriting factors: the type and size of tanks, materials used, proximity to populated areas or waterways, claims history, the length and location of projects, contractor experience, and the existence of safety programs or certifications. The use of heavy equipment, transport distances (commercial auto exposure), and whether hazardous fluids are handled will also affect rates.
Proof of insurance & compliance
Clients and site owners often require certificates of insurance, additional insured endorsements, and pollution liability limits before work begins. Maintaining proper subcontractor management, documented safety procedures, and equipment maintenance records helps satisfy contract requirements and may influence underwriting.
How to get a quote
Gather basic information about your operation (types of tanks, project examples, payroll and revenue, equipment list, and loss history) and share it with a broker. For detailed policy comparison and to review appropriate limits and endorsements, talk to your agent.
Frequently Asked Questions
Do I need separate environmental coverage?
Often yes — standard liability policies may have limited pollution coverage, so contractors handling fuels or chemicals typically add pollution liability or environmental endorsements.
Will my equipment be covered if it’s damaged during erection?
Contractors’ equipment or inland marine coverage can protect tools and mobile machinery; check policy limits and any specified exclusions for cranes or rented equipment.
Are subcontractors covered under my policy?
Coverage for subcontractors depends on contract terms and endorsements. Many owners require subcontractors to provide their own insurance or be named as additional insureds on the contractor’s policy.
