A Jetty Equipment Overhaul
Jetty equipment plays a crucial role in ensuring the smooth, safe, and efficient operation of ship loading and unloading operations. Over time, the mechanical, hydraulic, and structural components of piercing equipment experience wear and tear due to operational loads, marine corrosion, and aging. Therefore, overhauling is necessary as part of a regular maintenance program to restore the equipment to its original factory specifications.
Overhauling is a process of thorough inspection, disassembly, repair, replacement of damaged or worn components, reassembly, and functional testing to ensure the equipment operates safely and reliably.
Introduction
Overhaul Objectives
The objectives of overhauling jetty equipment are :
To select and maintain operational safety.
To reduce the risk of sudden breakdowns.
To extend the service life of equipment.
To meet regulatory requirements and occupational safety standards.
To reduce the risk of accidents and environmental pollution.
To maintain the continuity of terminal or port operations.
