Flag Change – What Happens to Class Notations?

 When a ship changes flag (re-flagging), the effect on class notations depends on whether the classification society remains the same or changes.

Case 1: Flag Changes, Class Society Remains the Same

Example: Ship changes from Panama flag to Indian flag but remains with DNV

✅ What Happens?

  • Class notations remain unchanged

  • Hull & machinery class continue as before

  • Additional notations (E0, DP2, Ice class, etc.) remain valid

  • Class certificate remains continuous (no break in class)

⚠ However:

  • Statutory certificates must be re-issued under the new flag

  • New flag state endorsements required

  • Carving & Marking note updated


Case 2: Flag Changes AND Class Society Changes

Example: From Lloyd's Register to Indian Register of Shipping

✅ What Happens?

  • Previous class is withdrawn

  • New class society conducts:

    • Transfer of Class (TOC) survey

    • Review of records

    • Condition of Class (if any)

  • New class notations issued as per new society rules

⚠ Important:

  • Notations may change format (symbols differ between societies)

  • Equivalent notation may be given

  • Some additional notations may require fresh verification


Important Distinction

Item                        Effect of Flag Change
Class Notation                               No change if class society same
Statutory Certificates                 Always re-issued under new flag
Class Certificate               Continues if class unchanged
CSR / Ice / DP notation               Continues if class unchanged

Manganese bronze is not typically used as a propeller material .Why

1. High cost: Manganese bronze is a costly alloy, making it less economical for large propellers. 2. Low strength-to-weight ratio: Compared to other propeller materials like nickel-aluminum bronze or stainless steel, manganese bronze has a lower strength-to-weight ratio. 3. Susceptible to corrosion: Manganese bronze can corrode in seawater, especially when exposed to high velocities and turbulence. 4. Poor cavitation resistance: Manganese bronze is more prone to cavitation damage than other materials. 5. Difficult to cast and machine: Manganese bronze is challenging to cast and machine, making it less desirable for complex propeller geometries. 6. Limited weldability: Manganese bronze has poor weldability, making repairs and modifications difficult. Nickel-aluminum bronze or stainless steel are commonly used for propellers due to their: - High strength and durability - Excellent corrosion resistance - Good cavitation resistance - Ease of casting and machining - Weldability

Main engine interlocks

Interlocks are provided so that the engine can be started or reversed only when certain conditions have been fulfilled. When there is a remote control of engines, it is essential to have interlocks. This reduces the possibility of engine damage and any hazards to the operating personnel. Turning gear Interlock . This device prevents the engine from being started if the Turning gear is engaged. Running Direction Interlock . This prevents the fuel from being supplied if the running direction of the engine does not match the Telegraph. Starting Air Distributor in end position . This prevents starting from taking place if the shifting of the Distributor has not been completed. Main Lube. oil pressure, Piston cooling pressure, Jacket water pressure, and important parameters must be above the required minimum. Auxiliary Blower Interlock . The Auxiliary Blower is provided in case of Constant pressure turbo charging. Air Spring pressure Interlock . In case of the present generation...

MAN B&W MC Engine VIT Pump

The pump is basically a jerk type with a plunger moving in a matched barrel, using two helical grooves machined in the plunger to control the end of injection by uncovering spill ports and causing the discharge pressure to drop rapidly, thus causing the needle valve in the injector to close. Oil is supplied to the barrel via the spill ports and a suction valve. The suction valve, situated at the top of the barrel opens when the pressure in the  barrel falls below the supply pump pressure; i.e. during downward stroke of plunger, while spill ports are covered by plunger. Replaceable erosion plugs  are fitted in the pump housing opposite the spill ports. The high pressure oil, spilling back, as the edge of the helix uncovers the s...
