Project Overview
Vessel: Oil Tanker
Location: HATSAN Shipyard, Türkiye
Flag: Marshall Islands
Equipment Installed: EDEL-EMES60 Speed Log System
Service Provider: Elektro Deniz
Date: June 2026
Summary
The project was executed by Elektro Deniz at the Hatsan Shipyard. The primary objective was to replace a defective Doppler speed log with a modern, high-precision system while the vessel was dry-docked. The technical team successfully completed the mechanical installation, electrical wiring, and system simulation, ensuring complete data integration across multiple bridge navigation systems.
Installation Scope
The project team carried out the following tasks:
Phase 1: Mechanical Deconstruction and Installation
- The old Doppler sensor was extracted, and the forward connection box was uninstalled.
- The old hull flange was cut out. A new flange was welded into place, and the new S-Valve was mechanically mounted.
- The new sensor cables were routed through fireproof, watertight transit glands to ensure maritime safety compliance.
Phase 2: Electrical Integration and Bridge Upgrades
- The old display unit on the bridge was replaced with the new EDEL-EMES60 Display Unit.
- In the electronics room, legacy wiring connected to the old processor was dismantled. These cables were rerouted and terminated into the newly installed EDEL-EMES60 Dual Interface unit.
- The system utilized the vessel’s existing 24VDC power network as its primary power source.
The retrofitted hardware consisted of the following components:
- EDEL-EMES60 Display Unit
- EDEL-EMES60 Sensor Interface
- EDEL-EMES60 Sensor Power Supply Unit
- EDEL-EMES60 Speed Log Sensor Unit
Testing
Since the ship was still in the shipyard, actual speed-through-water data could not be generated naturally. To bypass this obstacle and verify system integrity, the service engineers booted the EDEL-EMES60 Speed Log system into ”Simulation Mode”.
The simulation successfully transmitted speed data across the vessel’s local data network. Verification checks confirmed that NMEA speed data was being perfectly received by:
- 2x Marine Radar Units
- 2x ECDIS Systems
- Bridge Speed Log Display Indicators
- The Voyage Data Recorder (VDR)
The system was handed over to the Chief Officer and ship crew in fully operational condition, with a notation that final sea calibration must take place immediately after the vessel leaves the dry dock and is afloat.
Conclusion
The installation aboard OIL TANKER demonstrates Elektro Deniz’s capability to execute complete marine navigation retrofits, from equipment replacement and mechanical adaptation to electrical integration and commissioning. The successful deployment of the EDEL-EMES60 Speed Log System delivered a modern, reliable speed measurement solution ready for operational service.
