Marport trawl monitoring system installation and service
NAVION installs, calibrates and services Marport trawl monitoring systems on fishing vessels calling at ports in Busan, Vladivostok and China. As a Marport dealer we supply sensors, receivers and spares, configure Mosa2 and Scala2, and verify the readings at sea. The scope is planned to finish inside the port call.
Message us on TelegramNAVION is a Marport dealer, and trawl monitoring is the work our engineers do most often in Busan. Most jobs run inside a port call: the vessel comes alongside at Gamcheon fishing port or a Yeongdo repair yard, the crew hands over a list of sensors that stopped reporting on the last trip, and the system has to be working again before she sails. We plan Marport installation and repair around that window, not around a workshop schedule.
What the job includes
- Full Marport system installation
- Hull transducer and receiver replacement
- Sensor commissioning and channel planning
- Scala2 setup and display configuration
- Trawl sensor calibration checks
- Acoustic noise and interference survey
- Sensor charger and battery service
- Firmware and software updates
- Sea-trial verification
- Sensor and spare parts supply
Timing
- Sensor swap and reconfiguration
- typically 2-4 hours
- Receiver and Scala2 on an existing wet end
- typically 4-8 hours alongside
- Full install with new hull transducer
- usually 1-3 days, dock time needed
- Acoustic noise and interference survey
- typically half a day
- Sea-trial verification
- on the outbound run
What we need from the vessel
- Access to the wheelhouse console, the sensor locker and the trawl deck, with net-mounted sensors reachable
- Ship's power available on the console circuits for the receiver and the Scala2 PC
- A crew member who knows the gear: door type and size, warp marks, headline configuration and normal spread
- Machinery available to run during a noise survey, including hydraulics, refrigeration and thrusters
- Dock time and yard approval if a new hull penetration or a wet-end change is in scope
- Berth area, ETA and ETD confirmed in advance so the scope can be cut to the port call
Documents issued
- Sensor and channel assignment list with serial numbers and firmware versions
- Saved Scala2 workspace and Mosa2 sensor configuration backup
- Service report listing faults found, tests carried out and parts replaced
- Sea-trial verification notes with the readings checked against reference sources
- Cable and installation record for a new hull transducer or receiver fit
Frequently asked
Are you an authorized Marport dealer?
Yes. NAVION is a Marport dealer, so we supply sensors, receivers, chargers, cables and spare parts as well as installing and servicing them. We also work with sub-dealers and equipment vendors who need an engineer in Busan.
Can a complete system be fitted while the vessel is alongside?
Sensors, receiver, Scala2 PC and configuration can normally be done alongside. A new hull penetration for a transducer needs dock time and yard approval, so if the wet end is being renewed we plan it around a docking rather than a working port call.
