Chapter 5: General Insurance Products – Part 3 (Engineering & Other Insurances)
Part 2 of 6: Operational Phase Engineering Insurances
1. Overview of Operational Phase Engineering Insurances
Operational phase engineering insurances are designed to protect commercial, industrial, and manufacturing enterprises against sudden, unexpected physical loss or operational disruption after project commissioning. While construction-phase covers (such as C.A.R. and E.A.R.) protect projects during setup, operational engineering policies protect active plant, machinery, pressure vessels, and electronic systems during daily production.
| Category | Insurance Product | Primary Coverage / Purpose |
|---|---|---|
| Machinery & Plant | Machinery Breakdown (MB) | Covers accidental and unforeseen physical breakdown of insured machinery |
| Contractor's Plant & Machinery (CPM) | Covers specified loss or damage to construction plant and machinery used by contractors | |
| Pressure & Power | Boiler & Pressure Plant (BPP) | Covers specified risks associated with boilers and other pressure plants |
| Deterioration of Stock (DOS) | Covers deterioration or spoilage of stock following specified breakdown or interruption of refrigeration equipment | |
| Digital & Business | Electronic Equipment Insurance (EEI) | Covers specified physical loss or damage to electronic equipment |
| Machinery Loss of Profits (MLOP) | Covers consequential loss of profit/business interruption following insured machinery breakdown |
General insurance companies maintain specialized underwriting and risk engineering departments to evaluate these physical and operational exposures.
2. Machinery Breakdown (MB) Insurance Policy
Core Concept and Purpose
The Machinery Breakdown (MB) Policy provides comprehensive financial coverage for operational plant and machinery against sudden, accidental physical damage resulting from internal mechanical or electrical failures. Unlike standard Fire policies, which cover external perils like fire and atmospheric storms, the MB policy specifically covers internal operational hazards.
Insured Subject Matter
Eligible machinery under an MB policy includes:
- Electrical Equipment: Generators, electric motors, transformers, switchgear, and circuit breakers.
- Mechanical Equipment: Turbines, internal combustion engines, pumps, compressors, and transmission gearing.
- Industrial Process Plant: Cold rolling mills, conveyor systems, paper manufacturing machines, and textile looms.
Covered Perils
- Electrical Perils: Short-circuits, over-voltage, arcing, insulation failure, corona discharge, and electrical failure.
- Mechanical Perils: Centrifugal disruption, mechanical breakdown, fatigue, vibration, alignment failure, and physical impact.
- Human Errors & Operational Failures: Maloperation, lack of skill, carelessness, entry of foreign bodies, and water hammer effects.
Sum Insured Basis & Valuation
The Sum Insured under a Machinery Breakdown policy must always equal the Current Replacement Value of the insured machinery. This includes the new replacement cost of an identical machine, freight charges, customs duty, and erection costs.
Sum Insured = New Machinery Replacement Price + Transit Freight + Import / Customs Duties + Erection & Installation Charges
Loss Settlement & Underinsurance Formula
- Partial Loss / Repair Claims: The policy pays the full cost of repairs, including spare parts, labor, and transport, without applying depreciation on parts replaced.
- Total Loss Claims: Settled on Actual Cash Value (Replacement Value minus Depreciation).
- Condition of Average: If the Sum Insured is less than the true replacement value at the time of loss, the claim payment is reduced proportionally.
Formula for underinsurance calculation:
Claim Payable = Net Loss Amount * (Sum Insured / Current New Replacement Value)
3. Boiler and Pressure Plant (BPP) Insurance
Purpose and Statutory Scope
The Boiler and Pressure Plant (BPP) Policy provides specialized coverage for steam boilers, pressure vessels, and piping systems subject to internal pressure or vacuum. Because high-pressure vessels carry severe explosion and implosion risks, this policy is essential for manufacturing facilities, power stations, and chemical process industries.
Scope of Coverage
The BPP policy covers physical loss or damage caused by explosion or implosion of the insured pressure vessels during normal operational working:
- Damage to Insured Boilers & Vessels: Physical destruction or damage to the boiler or pressure plant itself.
- Surrounding Property Damage: Loss or damage to the insured's own surrounding property (e.g., plant buildings, adjacent machinery) directly resulting from the explosion or implosion.
- Third-Party Liability: Legal liability for bodily injury, death, or property damage suffered by third parties due to an explosion or implosion on the premises.
Exclusions & Statutory Inspections
- Exclusions: Normal wear and tear, gradual corrosion, scaling, willful act or gross negligence, and failure of safety valves to operate.
- Statutory Condition: Boilers must be regularly inspected and certified by authorized statutory boiler inspectors in accordance with applicable legal regulations.
4. Machinery Loss of Profits (MLOP) Policy
Concept and Strategic Function
The Machinery Loss of Profits (MLOP) Policy—also known as Business Interruption (Engineering) Insurance—compensates an enterprise for financial losses following an operational breakdown covered under a Machinery Breakdown (MB) or Boiler and Pressure Plant (BPP) policy.
While the primary MB or BPP policy pays for physical repairs, the MLOP policy covers the resulting loss of business revenue during the disruption period.
Insured Financial Elements
- Loss of Gross Profit: Reduced net trading profit due to lower production volume or sales turnover.
- Standing Charges: Fixed operational expenses that continue despite production stoppage (e.g., employee salaries, factory rent, bank interest, insurance premiums, and administrative overheads).
- Increased Cost of Working (ICOW): Additional expenses incurred to maintain production during the interruption (e.g., renting temporary machinery, outsourcing processing, or paying overtime).
Underlying Material Damage Warranty
An MLOP claim is admissible only if there is a valid, accepted claim under the corresponding primary MB or BPP policy for the physical breakdown event.
5. Deterioration of Stock (DOS) Policy
Operational Application
The Deterioration of Stock (DOS) Policy is designed for commercial cold storages, food processing plants, pharmaceutical storage facilities, and chemical warehouses. It covers financial loss resulting from the spoilage or decay of temperature-sensitive stored goods.
Trigger Perils
Coverage is triggered when stock deteriorates as a direct result of:
- Accidental physical breakdown of refrigeration plant and machinery covered under an MB policy.
- Accidental variation or rise in cold storage room temperatures due to refrigerant gas leakage.
- Sudden failure of the main public electric power supply exceeding an agreed threshold period.
Sum Insured & Valuation
The Sum Insured represents the maximum market value of stored temperature-sensitive stock during the policy period, often structured on a declaration basis for fluctuating inventory levels.
6. Electronic Equipment Insurance (EEI) Policy
Comprehensive Multi-Section Coverage
The Electronic Equipment Insurance (EEI) Policy covers low-voltage electronic and digital systems, computers, medical diagnostic equipment, telecommunications infrastructure, and data processing centers. It operates on an "All Risk" basis, covering sudden physical loss or damage from any cause not specifically excluded.
| Section | Coverage | Core Scope |
|---|---|---|
| Section I | Material Damage | Covers physical loss or damage to electronic equipment, hardware, and systems from insured risks |
| Section II | External Data Media | Covers physical loss or damage to external data-carrying media, subject to policy terms |
| Section III | Increased Cost of Working (ICOW) | Covers additional expenditure incurred to maintain or restore operations following insured damage to electronic equipment |
Detailed Policy Sections
- Section 1: Material Damage: Covers physical loss or damage to electronic hardware, microprocessors, diagnostic displays, and peripheral equipment from short-circuits, power surges, water ingress, fire, burglary, and operator error.
- Section 2: External Data Media: Reimburses the cost of replacing damaged external data storage media (disks, tapes, drives) and restoring lost data.
- Section 3: Increased Cost of Working (ICOW): Indemnifies the insured for extra operational costs incurred to maintain data processing operations using substitute computer equipment following a covered hardware loss.
Portable Equipment Extension
Laptops, portable diagnostic equipment, and mobile electronic gear can be covered worldwide against accidental damage and theft under specialized portable equipment extensions.
7. Contractor's Plant and Machinery (CPM) Policy
Purpose and Scope
The Contractor's Plant and Machinery (CPM) Policy provides "All Risk" physical loss or damage cover for mobile construction machinery, earth-moving equipment, and plant used at construction sites or commercial premises.
Insured Machinery Types
- Excavators, bulldozers, backhoes, and trenchers
- Tower cranes, mobile cranes, and concrete pumps
- Piling rigs, road rollers, and asphalt pavers
Coverage Environment
CPM policies protect equipment whether it is working, standing idle, or being dismantled for maintenance at specified job sites.
