Onshore Power Supply (opS)
Onshore power supply (OPS) enables electrical power from the shore to a ship at berth while its main & auxiliary engines are turned off. Consequently, It significantly reduces pollutants emissions and greenhouse gases while the ship is at berth. Furthermore, Onshore Power Supply (OPS) reduces noise, lowers costs, and enhances the working conditions for seafarers aboard the vessel.
The OPS consists of Ehouse and electrical equipment specifically designed to meet demands of the port.. Usually, the equipment includes switchgear, transformers, and frequency converters. Technical equipment is used to adapt the shore’s electrical characteristics, such as voltage and frequency, to match those of the ship.
OPS systems come in five different types, each designed to suit port requirements and vessel categories:
- HVSC Systems
- LVSC Systems
- Hybrid OPS
- DC System
- Mobile OPS
Based on our situational analysis, we offer a customized solution for Onshore Power Supply (OPS). With our in-house capability, we deliver a single-source solution under our complete control. This includes E-houses and electrical equipment specifically tailored to meet the unique needs of each port.
When selecting the appropriate OPS type, it’s important to consider key factors such as power demand, port infrastructure, type of vessel and voltage level.
