Practical electrical work, PLC control and energy-system integration for vessels.
Wattlab supports shipowners and yards with practical electrical work on board. We help with troubleshooting, modifications to distribution panels, replacing components, connecting new equipment and checking whether installations are safe, logical and easy to maintain.
We design, program and modify PLC systems for onboard installations. Wattlab has experience with CODESYS, WAGO 750 I/O systems, Modbus communication and practical start/stop logic for energy systems. Typical applications include PV systems, battery systems, pumps, ventilation, alarms, interlocks and interfaces with the vessel’s IAS or automation system.
Good decisions start with reliable data. Wattlab installs temporary or permanent measurement systems to monitor voltage, current, power, energy use, generator load, PV production or battery behaviour. We can use power meters, Modbus devices, data loggers and remote dashboards to give clear insight into how a vessel is actually operating.
Wattlab helps integrate solar PV and battery systems into existing vessel electrical installations. This includes AC combiner cabinets, transformers, inverters, contactors, protection devices, monitoring and control logic. We make sure new energy systems work safely and reliably together with the onboard grid, generator and existing switchboard.
Many onboard upgrades require a new or modified cabinet. Wattlab can design, build, modify and test small distribution cabinets, PLC cabinets, measurement cabinets and AC combiner cabinets. We work with components such as MCCBs, MCBs, RCBOs, contactors, 24 VDC power supplies, relays, WAGO modules and energy meters.
Modern onboard systems often depend on communication between devices. Wattlab can help troubleshoot Modbus RTU, Modbus TCP, RS485, Ethernet gateways, energy meters, inverters and PLC connections. We check wiring, addressing, termination, settings and data traffic, and can also set up remote access for faster support.
Small control circuits are often critical for reliable operation. Wattlab works on 24 VDC systems, relay logic, sensors, alarm contacts and control signals between installations. Examples include “Available”, “Running”, “Fault”, “Start” and “Stop” signals between a PV/battery system and the vessel’s IAS or switchboard control.
Wattlab supports shipowners and yards with practical advice for onboard energy upgrades. We help assess solar PV, batteries, generator optimisation, shore power and monitoring systems. Based on real measurements and vessel operation, we can translate ideas into a clear electrical concept that is realistic to install and maintain on board.
