Tianjin ZhuoLiNeng (ZLN) Technology Co., Ltd. is a professional manufacturer with over a decade of experience in electrolytic seawater chlorination systems. Our Offshore Platform Biofouling Control: Electrolytic Seawater Chlorination System with Skid Mounted Design is engineered specifically to combat marine biofouling in demanding offshore environments. By producing sodium hypochlorite on-site from seawater, this system eliminates the need for chemical transportation and storage, ensuring continuous and cost-effective protection for seawater cooling lines, fire-fighting systems, and injection water systems. The skid-mounted design allows for compact installation on space-constrained platforms, with quick deployment and minimal maintenance requirements. Whether for new builds or retrofits, our solution delivers reliable, environmentally responsible biofouling control.
Key Features & Technical Specifications
Electrolytic Cell Technology: Utilizes advanced mixed metal oxide (MMO) coated titanium electrodes for high efficiency and long service life (5–8 years).
Skid Mounted Design: Pre-assembled and tested on a structural steel skid, reducing on-site installation time and labor costs.
Automated Control: PLC-based control with intuitive HMI touchscreen, providing real-time monitoring of chlorine production, salinity, temperature, and flow rate. Remote SCADA connectivity is available upon request.
Low Maintenance: Self-cleaning electrode polarity reversal minimizes scaling, and the system is designed for easy access to key components.
Material Construction: Seawater wetted parts are made from corrosion-resistant materials such as titanium, duplex stainless steel, and fiber-reinforced plastic (FRP).
Flexible Capacity: Standard capacities range from 1 kg/h to 100 kg/h of equivalent chlorine, with custom designs available for larger requirements.
Power Efficiency: Typical DC power consumption is 4.0–4.5 kWh per kg of chlorine produced.

Benefits for Your Offshore Operations
Eliminate Chemical Logistics: On-site generation removes the need for hazardous chemical transport and storage, enhancing safety and reducing operational costs.
Minimized Downtime: Automated self-cleaning and durable electrodes ensure continuous operation, with only routine inspections required.
Space-Saving: Skid-mounted configuration optimizes deck space, ideal for platforms where every square meter counts.
Environmentally Friendly: Produces a low-concentration sodium hypochlorite solution that degrades rapidly without harmful residues.
Scalability: Multiple units can be combined for larger capacities, or a single system can be customized to match your specific flow and dosage requirements.

Frequently Asked Questions
Q: How does the electrolytic seawater chlorination system prevent biofouling?
A: The system uses electrolysis to convert chloride ions in seawater into sodium hypochlorite (NaClO), which is then dosed into the water intake. This low-level disinfectant kills or repels marine organisms such as barnacles, mussels, and algae, preventing them from attaching to pipes and equipment.Q: What is the typical lifespan of the electrodes?
A: With proper operation and regular polarity reversal, the MMO coated titanium electrodes typically last 5–8 years before requiring replacement. Actual lifespan depends on salinity, water temperature, and operating current density.Q: Can the system be installed on existing offshore platforms?
A: Yes, the skid-mounted design allows for easy retrofitting. Our team can customize the skid footprint and piping connections to match the platform layout. We also offer modular designs for limited space applications.Q: What is the required maintenance routine?
A: Routine maintenance includes checking the electrolyte level, cleaning the electrodes (automatically via polarity reversal), inspecting pumps and valves, and calibrating the chlorine analyzer. A detailed maintenance manual is provided with each system.Q: Does the system work in low-temperature or high-turbidity seawater?
A: Yes, the electrolysis efficiency varies with temperature and turbidity, but the system is designed to operate effectively in seawater temperatures ranging from 2°C to 40°C and turbidity up to 100 NTU. For extreme conditions, we can adjust the electrode configuration and control parameters.Q: Do you provide remote monitoring and control?
A: Yes, remote monitoring via SCADA or cloud-based platforms is available as an optional feature. Our PLC supports Modbus TCP/IP protocol for seamless integration with your existing control network.Q: What certifications does the system hold?
A: Our manufacturing facility is certified. The system can be produced to meet various classification society requirements (e.g., ABS, DNV, Lloyd's) upon request. Please specify your required certifications when inquiring.Q: What is the delivery time and shipping port?
A: Standard systems are typically delivered within 10–12 weeks from order confirmation. Shipments are made from Tianjin Port, China. We can also arrange expedited delivery for urgent projects.
