Deepwell Cargo Pump Pre-Operation Check

Pre-operation inspection template for a deepwell cargo pump, focused on manual shaft rotation, cargo lubrication readiness, cavitation prevention, and current-relay trip verification before startup.

Inspection Details and Authorization

• Pump identification recorded
  Record pump name/number, vessel or facility location, and cargo line or tank served.
• Inspection performed by competent person
  Confirm the inspector is authorized and competent to perform the pre-operation check.
• Operating permit or startup authorization verified
  Confirm required work authorization, permit, or startup approval is in place before operation.
• Reference procedure available at point of use
  Confirm the applicable SOP or manufacturer procedure is available for the inspection and startup sequence.

Mechanical Readiness and Shaft Rotation

• Shaft rotates freely by hand through full travel
  Manually rotate the shaft to confirm smooth movement without binding, rubbing, or abnormal resistance.
• No abnormal noise, scraping, or mechanical interference observed
  During manual rotation, confirm there is no scraping, grinding, or intermittent contact indicating internal interference.
• Coupling, guards, and fasteners secure
  Verify accessible coupling components, guards, and fasteners are installed and secure before startup.
• Seal, stuffing box, or gland area shows no visible leakage beyond acceptable limits
  Inspect the seal area for leakage, damage, or signs of overheating. Record any non-conformance.

Cargo Lubrication and Suction Conditions

• Cargo lubrication available and correctly aligned
  Confirm the cargo-lubrication supply is available, valves are aligned correctly, and the pump is not starved of lubrication.
• Lubrication line pressure within acceptable range
  Record the lubrication line pressure and verify it is within the acceptable operating range.
• Suction path open and unobstructed
  Verify suction valves, strainers, and associated flow path are open and free of obstruction before operation.
• Cargo level and suction head adequate to prevent air entrainment
  Confirm cargo level, trim, and suction conditions are suitable to avoid air ingress or loss of prime.

Cavitation and Electrical Protection Verification

• Cavitation risk assessed as acceptable
  Verify operating conditions, suction head, and flow path are adequate to minimize cavitation risk before startup.
• Pump primed or ready for flooded suction condition
  Confirm the pump is properly primed or otherwise in the required ready condition before energizing.
• Current-relay trip setting verified
  Confirm the current-relay trip setting matches the approved operating setpoint for the pump and motor.
• Motor protection and overload devices in service
  Verify overloads, protection relays, and related electrical safeguards are enabled and not bypassed.

Work Area, PPE, and Final Release

• Work area clear of spills, obstructions, and ignition hazards
  Confirm the area around the pump is clean, dry where required, and free of trip, slip, and ignition hazards.
• Required PPE available and worn
  Verify required PPE is available and being worn for the task, such as gloves, eye protection, and hearing protection as applicable.
• Deficiencies documented and released for corrective action or startup
  Record any deficiencies, non-conformances, or corrective actions before authorizing startup.
