Steering Gear Vram Packing Replacement

Steering Gear VRAM Packing Renewal Job by Meera Marine

Meera Marine successfully executed the VRAM (Valve Remote Actuating Mechanism) packing renewal job for the steering gear system on board, ensuring smooth and leak-free operation of this critical control mechanism. The job was carried out with strict adherence to safety protocols, OEM specifications, and classification society requirements.

• Job Planning and Safety Precautions
  The steering gear system was isolated and secured in close coordination with the vessel's engineering team.
  Hydraulic pressure was safely released from the system and lock-out/tag-out procedures were followed to prevent accidental activation.
  Required tools, PPE, and OEM-specified packing materials were arranged in advance.
• Dismantling and Assessment
  The VRAM unit controlling the steering gear valve was carefully dismantled.
  Old packing materials were extracted using specialized tools without damaging sealing surfaces.
  Visual inspection of the valve stem, gland, and housing was conducted to check for wear, corrosion, or damage.
• Packing Renewal Process
  New packing rings (typically graphite or PTFE-based, as per OEM guidelines) were cut, staggered, and installed layer by layer to ensure uniform sealing.
  The gland follower was reinstalled and tightened evenly to achieve the correct compression on the packing set.
  Care was taken to avoid over-tightening, which could affect valve actuation or damage the stem
• Reassembly and Testing
  The VRAM was reassembled and reconnected to the hydraulic control line.
  The steering system was re-pressurized and function-tested, including rudder movement trials, to confirm leak-free operation and proper actuation of the valve.
  All gland areas were observed during operation to ensure no signs of hydraulic leakage.
• Documentation and Reporting
  A complete record of the job was maintained, including packing specifications, test results, and work completion certification.
  The system was handed over to ship staff after successful verification and reactivation of the steering gear.
  
  By carrying out this job with precision and compliance, Meera Marine reinforced its commitment to maintaining critical ship systems at the highest operational standards.
