COMMISSIONING & TESTING
From first power-up to first sea trial.
Marine automation systems must work correctly when the vessel leaves the dock. We provide commissioning, testing and integration services to verify that automation, control, monitoring and power systems perform as intended.

COMMISSIONING PHILOSOPHY
Commissioning is where engineering becomes a working vessel system.
Marine automation involves many interconnected systems, signals and equipment from different manufacturers. A successful commissioning process therefore requires more than checking individual components.
We verify the complete control chain — from field instrumentation and I/O to PLC logic, HMI interfaces, alarms, communication networks and higher-level vessel systems.
Our objective is simple: when the vessel enters operation, the automation system should behave as a complete and predictable system rather than a collection of individual components.
OUR PROCESS
Structured commissioning from FAT to sea.
Each commissioning project is planned around the vessel, automation architecture and contractual test requirements. Testing progresses from individual functions to complete operational scenarios.
Factory Acceptance Test
Verification of PLC software, HMI screens, alarm functions, control sequences, communication and system behaviour before delivery or installation.
Site & Installation Verification
I/O checks, panel verification, field wiring checks, network connectivity and communication testing after equipment is installed onboard.
Site Acceptance Testing
Functional testing of the installed system together with machinery interfaces, alarms, interlocks and operator controls.
Harbour Tests
Integrated operational tests under controlled conditions before departure, including generator, machinery and vessel control sequences.
Sea Trial Support
Verification of system performance during actual vessel operation, including control sequences, power management and integrated machinery functions.
Final Verification
Final functional checks, documentation, outstanding issue resolution and support during system handover to the vessel’s operating team.
WHAT WE VERIFY
Testing the complete control chain.
Commissioning becomes especially important when multiple systems and equipment suppliers must operate together. We focus on the interfaces between systems as much as the individual systems themselves.
Automation & Control
PLC sequences, automatic and manual modes, control loops, permissives, interlocks and machinery control.
Alarms & Safety Functions
Alarm generation, priorities, acknowledgement, shutdown functions and operator indications.
Communication & Integration
Communication between PLCs, HMIs, IAS, PMS, generators, propulsion systems and third-party equipment.
Power Management
Generator control, synchronisation, load sharing, breaker sequences and power management functions.
ONBOARD COMMISSIONING
Problems are easier to solve before they become operational problems.
Our commissioning engineers work directly with vessel systems, electricians, shipyards, machinery suppliers and other automation contractors to identify and resolve integration problems.
One team at the interface.
When different systems meet onboard, the problem is often not inside one system — it is between them. We approach commissioning from the complete vessel perspective.
