Have you ever wondered what keeps those giant ships at Chittagong Port gliding smoothly through the water? It’s not just powerful engines or skilled crews—it’s also what happens beneath the surface. Underwater hull cleaning in Chittagong is the unsung hero of maritime efficiency, saving money, fuel, and the environment. In the busy shipping lanes of Chittagong, where every minute counts and every drop of fuel matters, hull cleaning is more than maintenance—it’s a necessity.
The Science Behind Hull Fouling in Chittagong
Imagine dragging a heavy net behind your bicycle. That’s what a ship experiences when marine organisms like barnacles, algae, and mussels attach themselves to the hull. This “biofouling” increases drag, forcing engines to work harder and burn more fuel. Over time, even a thin layer of slime can reduce a ship’s speed and efficiency by up to 10%. Left unchecked, heavy fouling can cost shipowners thousands in extra fuel every day and even damage expensive anti-fouling coatings.
Chittagong Port is the beating heart of Bangladesh’s international trade. Handling over 90% of the country’s import-export cargo, it’s a hive of activity with vessels arriving from all corners of the globe. The port’s tropical climate and nutrient-rich waters, however, accelerate marine growth on ships’ hulls. This makes regular underwater cleaning not just a good idea, but an operational must for vessels calling at Chittagong.
What Is Underwater Hull Cleaning in Chittagong?
Underwater hull cleaning in Chittagong is exactly what it sounds like: skilled divers or remote-operated machines remove biofouling from a ship’s submerged surfaces while it’s still afloat. This process targets the flat bottom, vertical sides, sea chest grates, rudder, and even the propeller. The goal? Restore the hull’s smoothness, reduce drag, and boost fuel efficiency—without the need for costly dry-docking.
Methods Used for Underwater Hull Cleaning in Chittagong
Underwater hull cleaning in Chittagong has evolved with technology. Here’s what’s commonly used:
- Rotating Brush Machines: These hydraulic carts scrub away barnacles and algae, leaving the hull clean but undamaged.
- High-Pressure Water Jets: For stubborn growth, water jets blast away fouling without harming the paint.
- Remote Operated Vehicles (ROVs): Some companies deploy ROVs equipped with cameras and cleaning tools, allowing for precise, diver-free cleaning, ideal for safety and efficiency.
- CCTV Inspections: Before and after cleaning, full video surveys document the hull’s condition, giving owners peace of mind and proof of service.
The best providers in Chittagong combine these methods for a tailored, thorough clean every time.
Environmental Impact and Green Practices of Underwater Hull Cleaning in Chittagong
The maritime world is under pressure to go green, and hull cleaning is no exception. Modern services in Chittagong are adopting eco-friendly practices:
- Filtration Systems: Advanced units capture debris and prevent harmful organisms from re-entering the port’s ecosystem.
- Biocide-Free Cleaning: Instead of harsh chemicals, most cleaning now relies on mechanical or water-based methods.
- Compliance with International Standards: Reputable companies follow IMO guidelines, ensuring safe, sustainable operations that protect both the ship and the sea.
By choosing green hull cleaning, shipowners help prevent the spread of invasive species and keep Chittagong’s waters healthy for future generations.
