Inspection Details and Authorization

Record pump name/number, vessel or facility location, and cargo line or tank served.
Confirm the inspector is authorized and competent to perform the pre-operation check.
Confirm required work authorization, permit, or startup approval is in place before operation.
Confirm the applicable SOP or manufacturer procedure is available for the inspection and startup sequence.

Mechanical Readiness and Shaft Rotation

Manually rotate the shaft to confirm smooth movement without binding, rubbing, or abnormal resistance.
During manual rotation, confirm there is no scraping, grinding, or intermittent contact indicating internal interference.
Verify accessible coupling components, guards, and fasteners are installed and secure before startup.
Inspect the seal area for leakage, damage, or signs of overheating. Record any non-conformance.

Cargo Lubrication and Suction Conditions

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

Cavitation and Electrical Protection Verification

Verify operating conditions, suction head, and flow path are adequate to minimize cavitation risk before startup.
Confirm the pump is properly primed or otherwise in the required ready condition before energizing.
Confirm the current-relay trip setting matches the approved operating setpoint for the pump and motor.
Verify overloads, protection relays, and related electrical safeguards are enabled and not bypassed.

Work Area, PPE, and Final Release

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