Audit & Troubleshooting

An electronics failure can stop a departure, a season, sometimes an entire crew. SEMA diagnoses onboard: NMEA network, power, sensors, displays, firmware. The goal is clear: identify the cause, repair cleanly, and document so it does not happen again.

Onboard diagnosis

Measurements, network analysis and sensor-by-sensor tests, without immobilising the vessel longer than needed.

What we cover

Key points

01

Urgent repair

24/48h intervention depending on the area for season-blocking failures (06 & 83).

02

Firmware updates

Charts, protocols and device compatibility: updates are part of the service.

03

Modernisation audit

On older vessels, we target what must be replaced without stripping everything.

Questions

Do you work on older vessels?

Yes. The audit identifies modernisation needs. We integrate current technology without altering the character of the boat.

What are your lead times?

Emergency (blocking failure): 24/48h depending on area. Full refit projects are planned off-season.
