Water-tube boilers
Water-tube boilers are commonly used on vessels requiring higher steam capacity or higher operating pressures. In this design, water flows through tubes that are heated externally by combustion gases.
This configuration allows for faster steam generation and improved performance in high-demand applications
Applications in the maritime industry
Water-tube boilers are often found on:
- LNG carriers
- Large tankers
- Offshore installations
- Vessels with high steam demand
Due to their more complex design, water-tube boilers require specialised knowledge during inspection and repair.
Typical operational challenges
Common issues include:
- Tube overheating and failure
- Scaling or contamination on water-side surfaces
- Burner performance issues
- Control system instability
These challenges can impact steam production and increase operational risk if not addressed
early.
