LV-Shorebox - Introduction

Organizations like World Ports Climate Initiative (WPCI), who strive to reduce the carbon footprint contain NO2 and NOX which have a negative influence on the air quality in port worldwide, look for a solution to this problem.A solution presents itself in Onshore Power Supply (OPS) systems. These systems provide electricity for vessels at berth by connecting the vessel with an OPS system:

Similar to seafaring vessels, inland shipping vessels face the same problem when at berth. For on board power both rely on diesel generators which in turn produce harmful exhaust gasses. This has a negative influence in the green image of ports.

LV-Shorebox - Explained

Technical Services provides OPS systems for both high power demanding seafaring vessels (MV-shorebox) as for inland shipping vessels (LV-shorebox).

The LV–Shorebox (Low Voltage – shorebox) has 2 connection points delivering 3x400V – 32A and 2 connections delivering  230V-20A. These connections provide power to the vessels.

The next step is monitoring the power (for billing purposes) and providing service in case a problem emerges. This is where the LV–Shorebox stands out from the rest. The systems runs on an in house custom build TECHMETRYS system. TECHMETRYS is a decentralized SCADA based system. This means that it consists of a main server and multiple independent connections (LV-Shoreboxes). The TECHMETRYS server is connected to the LV-Shoreboxes via a wireless 3G connection. Each LV-Shorebox has a PLC which measures the power being consumed of each separate connection point and in turn relays this information back to the main server via their 3G modem. The PLC also monitors the electric condition of the shorebox (ie differential faults,  phasepower loss, overcurrent,…..). The system provides the service engineers with a powerful tool.

When a fault occurs in a shorebox he will be automatically notified by email, describing which fault occurred, on which shorebox and providing a brief summary of other important parameters. Next the service engineer can go online and check the TECHMETRYS system for an overview of the real time situation of all installed LV-shoreboxes.

When an internet connection is available, access anywhere is possible.

The service engineer can choose between accessing either the MIMIC (a visual overview of the real time situation of the selected LV-shorebox:

or go to the detailed real time parameter overview:

In both cases it is possible to reset the connection point of the shorebox. This means that the service engineer is no longer required to physically go to the shorebox in case of an error.

This means that the service engineer is no longer required to physically go to the shorebox in case of an error.

LV-Shorebox - Web based platform

So far every technical aspect for power delivery and monitoring has been examined. A second and equally important aspect of this system is to provide a platform to communicate with vessels and providing vessels the opportunity to monitor their power consumption. TECHELEC
Technical Services provides a solution in the form of a web based platform:

Vessels can create a login providing the necessary details (phone number, ENI number,…). Once a Login is created and confirmed, vessels can lookup which LV-shorebox connections are available via a map:

or via list:

The next step is to activate the connection point closest to the vessel. Only after activation is done, power will be available at the socket. During consumption it is possible to monitor the amount in real-time:
