Explore our heavy-duty marine distribution panels, motor controllers, and switchboards certified by top-tier maritime classification societies for operations across Sri Lankan ports and international waters.
Sri Lanka stands at the crossroads of major Indian Ocean shipping routes. With the expansion of the Port of Colombo, Hambantota International Port, and Trincomalee Deep Water Harbor, combined with active shipbuilding and refit operations at Colombo Dockyard PLC, the operational demands placed on marine electrical systems have reached unprecedented levels of complexity.
Marine power distribution panels serve as the critical central nervous system for any sea-going vessel, offshore platform, or harbor service craft. They manage electrical power generation, frequency regulation, load dispatching, circuit protection, and seamless power transfer between main generators, auxiliary units, and shore power connections. When operating in Sri Lanka's tropical maritime environment, electrical switchboards face acute operational stressors including ambient temperatures exceeding 45°C in engine spaces, high relative humidity (frequently >85%), and aggressive C5-M marine salt corrosion.
As a specialized OEM/ODM factory and global supplier serving Sri Lankan shipbuilders, shipowners, and marine engineering firms, our distribution switchboards are custom-engineered from the ground up to mitigate these precise environmental and operational vulnerabilities, strictly adhering to IEC 61439-6, IEEE 45, and SOLAS standards.
High-conductivity E-CU copper busbars silver-plated at contact points, rated for thermal stability up to 105°C and short-circuit withstand strength (Icw) up to 100kA for 1 second.
Enclosures manufactured from cold-rolled steel or 316L stainless steel, treated with anti-corrosive zinc-rich epoxy primers and polyurethane topcoats exceeding 2400 hours of salt spray testing.
Our factory provides tailored ODM customization based on vessel single-line diagrams (SLD). Below are standard technical parameters designed for Sri Lanka commercial marine operations:

Sri Lanka's maritime industry requires specialized electrical distribution topologies across diverse vessel classes and shore facilities. Our factory delivers optimized OEM solutions tailored to local maritime workflows:
High-vibration resistant, compact motor starter panels and main distribution switchboards equipped with integrated soft-starters or frequency converters for variable-pitch propulsion winches and heavy towing gear.
Custom ODM switchboard drop-in replacement units designed to match existing legacy mounting dimensions while upgrading internal breaker technology to modern air circuit breakers (ACB) and molded case breakers (MCCB).
Sealed IP66 auxiliary power boxes and battery charging distribution panels designed for high humidity, engine room thermal build-up, and direct salt water exposure common on regional fishing vessels.
Shock-tested, low electro-magnetic interference (EMI) distribution panels built for continuous defense operations in Indian Ocean territorial waters, adhering to stringent military-grade marine electrical standards.
As international maritime environmental policies tighten, Sri Lankan maritime operators are rapidly adapting to modernization trends. Our ODM engineering factory works directly with regional partners to integrate next-generation technologies:
1. Shore-to-Ship Power (Alternative Maritime Power - AMP): To reduce carbon emissions at the Port of Colombo, shipowners are retrofitting vessels with specialized AMP distribution panels. Our switchboards incorporate high-capacity shore connection breaker interlocks, phase sequence indicators, and step-down isolation transformers to safely receive 50Hz/60Hz shore power.
2. Hybrid Electric Propulsion & Battery Power Management: With green tugboats and solar-hybrid passenger ferries gaining traction across South Asian ports, our factory designs advanced Power Management System (PMS) panels capable of dynamic load sharing between diesel generator sets, energy storage systems (ESS), and solar array inverters.
3. Smart Condition Monitoring & Predictive Maintenance: Modern marine switchboards engineered by our factory feature IoT-enabled thermal sensors on busbar joints, micro-insulation monitoring, and automated alarm outputs to detect electrical breakdown before catastrophic engine room power failures occur.
Leveraging over 50 years of combined industrial and marine engineering capability, our organization operates as a total one-stop partner for power distribution switchboards and electrical drives. We offer distinct strategic advantages for Sri Lankan clients:
From initial CAD schematic design, busbar calculation, sheet metal fabrication, and wiring to final Factory Acceptance Testing (FAT) overseen by class surveyors, we retain 100% control over product quality.
As specialized suppliers of marine electric motors and switchboards, our Motor Control Centers (MCC) are perfectly calibrated to motor start-up curves (DOL, Star-Delta, Soft-Starter, VFD), preventing voltage drop spikes.
Our streamlined export logistics channels guarantee fast air and sea freight delivery directly to Colombo port, Hambantota, or local shipyard bonded warehouses, backed by immediate spare parts availability.
Every marine distribution panel undergoes rigorous insulation testing, high-voltage withstand tests, dielectric verification, and dynamic operational simulation prior to export dispatch.
Our marine distribution switchboards are custom-engineered according to IEC 61439-1/2, IEC 60092 (Electrical Installations in Ships), and IEEE 45 guidelines. We work seamlessly with major classification societies including DNV, ABS, Lloyd's Register (LR), Bureau Veritas (BV), and Indian Register of Shipping (IRS). When requested during the ODM phase, we prepare full drawing packages for pre-approval by your assigned marine surveyor prior to manufacturing.
Standard marine distribution boxes and small auxiliary panels are typically produced within 2 to 3 weeks. Complex multi-section Main Switchboards (MSB) or Motor Control Centers (MCC) requiring specialized air circuit breakers (ACB) and Power Management System (PMS) integration usually require 4 to 6 weeks for manufacturing and Factory Acceptance Testing (FAT). Expedited logistics options to Colombo Port via express sea cargo or air freight are available for emergency refit projects.
Internal condensation is a leading cause of electrical arcing and short-circuits in tropical marine engine rooms. Our switchboards incorporate internal thermostatically-controlled anti-condensation space heaters, IP54/IP66 breathers with hydrophobic membranes, and localized tropicalized conformal coatings on all PCB control modules. Enclosures are also fitted with high-density neoprene/EPDM gaskets to seal against ambient moist air intrusion.
Yes. Our ODM engineering team specializes in retrofit engineering. By utilizing exact dimensional measurements and existing single-line diagrams provided by Sri Lankan ship repair yards, we engineer custom enclosure frames, busbar adaptors, and door cutouts. This guarantees seamless drop-in mechanical mounting and minimal vessel downtime during dockyard refits.
Every switchboard is delivered with a complete technical documentation dossier. This includes Factory Acceptance Test (FAT) reports, dielectric and insulation test certificates, Single Line Diagrams (SLD), 3D structural layout drawings, schematic wiring diagrams, complete bill of materials (BOM) with part numbers for easy spare ordering, and Class Society Type Approval certificates where applicable.
Absolutley. We routinely build double-busbar switchboards for critical dynamic positioning (DP2/DP3) offshore vessels, as well as ATEX / IECEx certified Ex-d and Ex-e explosion-proof control boxes for fuel barges, chemical tankers, and hazardous engine room zones.
