Price Structure and Parameter List of a Custom Small Marine Incinerator for Offshore Platforms and FPSOs (Anti-Seismic & Anti-Corrosion)
In the living quarters and machinery auxiliary zones of offshore engineering platforms (Jack-ups / Semi-submersibles), FPSOs (Floating Production Storage and Offloading), and offshore wind farm Service Operation Vessels (SOVs), a small but continuous volume of solid waste is generated daily. This must be compliantly disposed of, including galley waste (paper boxes, plastic utensils), rags, cut-off mooring ropes, and bilge waste oil/sludge.
Due to the strict limitations of platform deck load, compact space, and ISO standard anti-corrosion requirements, standard land-based incinerators or generic merchant ship incinerators cannot be directly applied. To solve this, operators must utilize a custom small marine incinerator (typically handling 50–100 kg/h or 50–80 kg/batch). These units are specifically engineered for ±22.5° roll / ±10° pitch, ISO C5-M salt spray anti-corrosion, and zero wash water discharge.
While satisfying the IMO MEPC.244(66) resolution and Classification Society (CCS/DNV/ABS/LR) Type Approval, a custom small marine incinerator tackles special offshore conditions through a monolithic seismic-resistant refractory lining, super duplex/316L stainless steel exposed parts, and a dry purification chain. Below, using typical FPSO domestic waste treatment as an example, we deconstruct the technical parameter list and price structure logic of this customized equipment.
Four Special Constraints of Offshore Platforms on a Custom Small Marine Incinerator
1. Extreme Roll and Vibration Endurance
An FPSO under severe sea conditions can experience rolling up to ±22.5° and pitching up to ±10°, with a cycle of 6–15 seconds.
If a brick lining is used, it will easily loosen and collapse under alternating inertial forces. It must utilize a monolithic low-cement refractory castable ($Al_2O_3 \ge 75\%$) poured as a single piece, densely packed with 310S/253MA anchor pins (≤120 mm spacing), and ceramic fiber sleeves on the claw ends.
All pipelines must be connected with stainless steel corrugated flexible hoses (316L or 321 material) to prevent rigid pipe fracture caused by hull deformation.
Components inside the electrical cabinet must be secured with anti-loosening nuts, and PCB boards treated with thread-locking adhesive, complying with the marine equipment vibration spectrum (IEC 60945).
2. C5-M Level Salt Spray Anti-Corrosion (ISO 12944)
The marine atmosphere contains high $Cl^-$ concentrations; the corrosion rate within 10 m of the sea surface can be 3 to 5 times that on land.
Shell: Vessel-grade carbon steel (Q345R/EH36) sandblasted to Sa 2.5 → Epoxy zinc-rich primer 80 μm (Zn≥80%) + Epoxy micaceous iron oxide intermediate coat 120 μm + Fluorocarbon/Polyurethane topcoat 80 μm (Total dry film $\ge 280\ \mu m$). Alternatively, 316L stainless steel cladding can be used (a high-tier platform option).
Exposed Bolts/Hinges/Handles: A4-80 (316 stainless steel) or Duplex steel 2205; 304 is strictly prohibited.
Chimney Inner Tube: 316L stainless steel, outer wall carbon steel with C5-M coating, deck penetration seat equipped with weather-tight flanges and flame arrestor mesh.
Control Cabinet: IP56 (offshore requirements are often higher than IP54), equipped with an internal anti-condensation heater (auto-starts if relative humidity >70%), and coated with conformal coating (three-proof paint).
3. Zero Liquid Discharge Limits (Dry Purification)
Most platforms prohibit discharging acidic scrubbing wastewater generated by the incinerator's rapid quench into the bilge.
Therefore, the system must select dry rapid quench + dry deacidification ($Ca(OH)_2$ powder injection) + activated carbon + PTFE bag filter dust removal.
The bag filter captures fly ash into a sealed ash drum (placed in the platform's hazardous waste storage). There is no continuous sewage discharge, only a very small amount of salt sludge (quarterly discharge can be connected to the platform's produced water system or collected in dedicated drums).
4. Space and Module Division
FPSO living modules/machinery auxiliary zones often only reserve a 1.5 × 1.2 m floor area, with highly restricted height (under beam 2.2–2.5 m).
The equipment is usually designed as a vertical compact dual-chamber + side-hung flat bag filter, with a total height $\le 2.4\text{ m}$ (removable top cover for phased installation).
Components can be divided into modules (combustion chamber module + purification module) to pass through platform hatches (typically 600×600 mm or 800×800 mm) and be bolted together afterward, making it highly suitable for retrofit projects.

These are non-negotiable items for FPSO class acceptance.
Installation and Commissioning Essentials on the Platform
Foundation: The platform pre-installs anchor bolts (M20 stainless steel A4-80 or 316). Use stainless steel leveling shims for the base. Secondary grouting must use non-shrink, high-strength mortar (salt-spray resistant).
Fixing: The equipment feet are welded to the platform (or bolted + lock nuts + lock washers) to prevent displacement from rolling.
Piping:
Fuel Pipe: Stainless steel 316L corrugated flexible hose connected to the daily oil tank (equipped with double shut-off valves + anti-static grounding).
Purge Air: Instrument air 7 bar connected to quick connectors (if equipped).
Discharge: The ash collection bin is equipped with a sealing cover and periodically transferred to the platform's hazardous waste temporary storage compartment.
Electrical: Main power goes through a dedicated circuit breaker on the platform distribution board. Alarm contacts (over-temperature/fault/emergency stop) are integrated into the machinery monitoring or PMS system.
Trial Run: FAT replicates SAT (Site Acceptance Test). Use simulated solid waste (wood chips + waste paper + a small amount of waste oil) to verify the secondary chamber reaches $\ge 850/1000^\circ\text{C}$, test alarm functions, and hardwired E-stops. A Classification Society surveyor must witness and sign off on-site.

The requirements for solid waste incineration equipment on offshore platforms and FPSOs go far beyond "just burning it." Under the IMO MEPC.244(66) framework, it must simultaneously satisfy C5-M level salt spray anti-corrosion, ±22.5° roll anti-seismic monolithic lining, zero wash water dry purification, and Classification Society Type Approval.
These special constraints dictate that the price structure and technical parameters of a custom small marine incinerator are fundamentally different from ordinary river/sea marine incinerators. With its platform-proven anti-seismic lining, super anti-corrosion shell, and complete marine document package, the BNTET custom small marine incinerator helps shipyards and offshore EPC contractors seamlessly pass plan approvals and sea trial acceptances—ensuring that platform living quarter waste is compliantly reduced to zero amidst the winds and waves of the Southern Ocean.
