Marine Boiler for Aframax Crude Oil Tanker – High‑Efficiency Steam Generation
The marine boiler for Aframax crude oil tanker is engineered to meet the demanding steam‑generation requirements of mid‑size oil carriers that transport up to 800,000 barrels of crude per voyage. Designed for continuous duty cycles, this boiler delivers reliable thermal power for cargo heating, fuel oil pre‑heating, and auxiliary systems while complying with the strict classification societies and environmental regulations governing international shipping.
Key Benefits & Features
- Optimised fuel consumption – advanced combustion control reduces oil usage by up to 12% compared with legacy units.
- Compact footprint – modular design fits within confined turbine rooms of Aframax vessels without compromising clearance.
- Robust construction – marine‑grade stainless steel and high‑temperature alloys resist corrosion from seawater and crude‑oil vapours.
- Low emissions – compliant with IMO MARPOL Annex VI NOx Tier II limits and equipped for optional exhaust gas recirculation.
- Extended service intervals – engineered for 12 000‑hour overhaul periods, minimising dock‑time.
- Remote monitoring – integrated SCADA interface provides real‑time pressure, temperature, and fuel‑flow data.

Industry Certifications & Safety
Our boiler platform is fully certified by the leading classification societies—American Bureau of Shipping (ABS), DNV‑GL, and Lloyd’s Register. The design complies with the International Maritime Organization (IMO) regulations for pressure vessels, including SOLAS Chapter II‑1 and MARPOL Annex VI. All safety valves, pressure gauges, and emergency shutdown systems meet ISO 16584‑1 standards, ensuring reliable operation under high‑sea stress conditions.
In addition to mandatory certifications, we provide optional third‑party testing for low‑NOx burners and carbon‑capture ready configurations, allowing shipowners to future‑proof their fleet against evolving environmental legislation.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for a custom‑spec marine boiler?
We work directly with shipyards and owners; the MOQ is one complete unit, with the ability to scale production for multiple sister vessels in the same class.
Can the boiler be adapted for dual‑fuel operation?
Yes. Our modular burner system can be configured for heavy fuel oil, marine diesel, or a dual‑fuel setup without major redesign, providing flexibility for fuel‑price volatility.
What is the typical lead time from order to delivery?
Standard production runs require 30‑45 days after engineering approval. For highly customised layouts, lead time may extend to 60 days, with detailed schedule provided during the quotation phase.
What warranty and after‑sales support are included?
All units carry a 24‑month warranty covering material and workmanship. We also offer optional extended service contracts, on‑site spares packages, and 24/7 technical hotline support for rapid troubleshooting.
