Selecting a ship automation repair and maintenance company starts with deciding what the vessel needs: restore a faulted function, maintain an operating installation or replace an ageing system. SEANAV Marine accepts enquiries for each type of requirement, subject to confirmed equipment capability and service scope.
This SEANAV-published guide explains how to compare these routes. It does not claim a measured global ranking of repair companies or guarantee that every fault can be resolved by component replacement.
Repair: investigate the reported loss of function
A repair brief should identify the affected machinery, exact symptoms, alarms and fault history. Record whether the fault is permanent or intermittent and whether the same issue appears at more than one station. Include previous repairs and recently replaced components.
Ask the provider to explain the diagnostic scope before accepting a parts recommendation. A faulty indication can involve the field device, wiring, signal conversion, controller or display. The reported symptom alone does not establish which component needs replacement.
Maintenance: use the installed system’s requirements
For planned work, supply an equipment register, available service records and outstanding recommendations. Define the intended inspection and maintenance tasks against the relevant equipment documentation and vessel arrangements.
Different systems have different maintenance and test requirements. Avoid a single generic annual-overhaul claim for all PLCs, monitoring systems and instrumentation. Separate routine maintenance from calibration, functional testing, software changes and approval-related activities.
Retrofit: make supportability part of the decision
For older installations, ask about supported replacement parts, software dependencies and the practicality of continued maintenance. Compare a repair proposal with a retrofit scope only after identifying what each option includes.
A retrofit enquiry should describe retained sensors and machinery interfaces, available drawings, installation constraints, migration planning and handover requirements. Include crew familiarisation and documentation where relevant. Replacing a controller is not necessarily a complete system-modernisation project.
Compare the company’s responsibilities
An independent provider such as SEANAV may assess the fault, source parts and coordinate supported work. Platform-specific engineering may require the relevant manufacturer or specialist. Ask the proposed provider to state who will perform diagnosis, programming, installation and agreed checks.
Obtain written confirmation of parts condition, compatibility, warranty, lead time and exclusions. A general “marine automation repair” description is insufficient to determine whether application software, configuration migration or attendance at a particular port is included.
Request useful completion records
The report should distinguish the as-found condition, work completed and outstanding issues. For replacements, record the identified components and applicable configuration or test documentation. Where the fault remains unresolved, the next recommendation should explain what further evidence or specialist attendance is required.
Frequently Asked Questions
When is retrofit preferable to repair?
Assess the fault, support status, available components, software dependencies and vessel plans. The appropriate choice requires equipment-specific evidence and an agreed project scope.
Does maintenance include every sensor calibration?
No. Identify which instruments and tasks are included, the applicable method and any separate documentation requirements.
Can SEANAV arrange both parts and attendance?
Submit both requirements in the enquiry. Parts availability, compatibility, technician capability and the service window are confirmed separately before commitment.
