Marine Pre Dry-Docking Inspection & Technical Assessment

A well-planned dry-docking period can significantly reduce vessel downtime, unexpected repair costs and delays. Hi Pro Electronics provides marine pre dry-docking inspection services focused on the vessel’s electrical, automation, control, instrumentation and electronic systems.

Our engineers inspect the existing equipment before the vessel enters dry dock, identify faults and obsolete components, assess systems requiring maintenance or upgrade, and prepare the technical information required for efficient dry-dock planning.

Prepare Before the Vessel Enters Dry Dock

Dry-docking provides a limited window for maintenance, repairs, modifications and system upgrades. Discovering technical problems only after the vessel enters the shipyard can result in additional costs, unavailable spare parts and delays to the vessel’s schedule.

A marine pre dry-docking inspection allows technical requirements to be identified in advance so that engineering work, spare parts, replacement equipment and specialist attendance can be properly planned.

Our Pre Dry-Docking Inspection Scope

Depending on the vessel and project requirements, our engineers can inspect and assess:

• Alarm Monitoring Systems (AMS)
• PLC and automation systems
• Human Machine Interfaces (HMI)
• Engine remote control systems
• Main and auxiliary engine safety systems
• Generator control and power management systems
• Switchboards and electrical distribution systems
• Tank gauging and level monitoring systems
• Fuel monitoring and measurement systems
• Boiler and burner control systems
• Inert gas systems
• Navigation and NMEA communication equipment
• Sensors, transmitters and instrumentation
• CCTV and monitoring systems
• Communication interfaces and industrial networks
• Obsolete PLC, HMI and electronic equipment
• Existing cabling, panels and field instrumentation

Obsolescence & Retrofit Assessment

Older vessels often operate with automation and electronic equipment that is no longer manufactured or supported by the original supplier.

During the inspection, Hi Pro Electronics can identify obsolete PLCs, HMIs, controllers, instrumentation and electronic modules and evaluate suitable replacement or migration solutions.

Where practical, we aim to retain serviceable existing equipment and infrastructure while replacing obsolete components with modern alternatives. This can reduce unnecessary modification work and simplify installation during dry dock.

PLC, HMI & Automation System Evaluation

Our engineers can review the condition and configuration of existing automation systems and identify potential requirements for:

PLC migration and upgrades
Assessment of obsolete PLC platforms, I/O modules, communication interfaces and control architecture.

HMI replacement
Evaluation of discontinued operator panels and possibilities for migration to modern HMI platforms.

Software backup
Where technically possible and authorized, backups of PLC, HMI and controller programs can be collected before dry dock.

Communication assessment
Review of Modbus, Profibus, CAN Bus, Ethernet, NMEA and other communication networks.

I/O and instrumentation checks
Identification of defective, unreliable or obsolete sensors, transmitters and interface equipment.

Troubleshooting Before Dry Dock

Existing technical problems can be investigated before the vessel reaches the shipyard.

Early troubleshooting helps determine whether a fault originates from field instrumentation, cabling, I/O modules, PLC logic, communication networks, HMI equipment or other control-system components.

This allows the appropriate equipment, engineering resources and spare parts to be prepared before the scheduled dry-docking period.

Spare Parts & Material Planning

Following the inspection, required materials can be identified in advance.

Depending on the findings, this may include:

• PLC and remote I/O components
• HMI panels
• Sensors and transmitters
• Relays and interface modules
• Communication gateways
• Industrial networking equipment
• Power supplies
• Control and instrumentation components
• Replacement electronic equipment
• Cables and installation materials

Early identification is particularly important when dealing with obsolete equipment or components with long delivery times.

Technical Inspection Report

Following the onboard inspection, Hi Pro Electronics can provide a structured technical report documenting the condition of the inspected systems and the recommended work.

The report may include equipment identification, observed faults, obsolescence issues, photographs, recommended corrective actions, proposed upgrades and required spare parts.

This information can then be used to define the technical scope for the upcoming dry-docking project.

From Inspection to Dry-Dock Execution

Our involvement does not have to end with the inspection.

Hi Pro Electronics can support the complete process from initial inspection and engineering assessment through procurement, system modification, installation, commissioning and sea trials.

By defining the technical scope before the vessel enters dry dock, shipowners and technical managers can better coordinate work with the shipyard and specialist service teams.

Marine Automation & Electrical Expertise

Hi Pro Electronics specializes in marine and industrial automation, electrical and electronic systems. Our experience includes troubleshooting, PLC and HMI migration, control-system modernization, instrumentation, communication interfaces and vessel monitoring systems.

Our objective during every marine pre dry-docking inspection is straightforward: identify technical requirements early and prepare a practical scope of work before valuable dry-dock time begins.
