Key Modifications (compared to the Base Design):

- Internal Layout: Revised interior arrangement and vessel communications within the existing compartments.
- Main Engine: Replaced with a ~150 HP diesel-reduction gear unit (based on the 3D6 diesel engine).
- Auxiliary Power: Installed a 20 kW AC diesel generator (3-phase, 50Hz, 380V).
- System Upgrades: Overhaul of heating, water treatment, sewage (black water), and fire-extinguishing systems.
- Navigation & Communication: Modernized suite including radio, bridge equipment, and GPS.
- Superstructure: Extended forward towards the bow.
- Steering Gear: Installation of twin rudders with a wire-rope steering drive.
- Towing Equipment: Installed a towing bitt for hook attachment (for towing astern).
 

Preserved Features:

The conversion retains the original hull, subdivision (compartment layout), and portions of the superstructure. Additionally, the following elements are preserved:
- Engine room casing and ladder access.
- Rubbing strake and mast.
- Shaft line and propeller.
- Anchoring and mooring equipment.
- Towing bitts for towing alongside.
- Specific engine room systems.
- Modular assembly principle (enabling reassembly of the hull, superstructure, and railings after rail transit without welding).
