Standard 5-Step Shaft Power Meter Calibration SOP
Our Class-approved technicians execute this standardized procedural workflow to ensure first-time compliance with attending Class surveyors and Indian Port State Control (PSC) inspectors:
-
Contactless Telemetry Power Ring & Receiver Gap Inspection
Inspect inductive power coils and RF transmitter rings on intermediate propeller shaft; verify 2-4mm airgap alignment.
-
Zero Torque Offset & Static Mechanical Balance Calibration
Perform static zero-point calibration with turning gear engaged in ahead and astern directions to cancel residual shaft twist.
-
Optical Pulse Tachometer & Shaft RPM Sensor Verification
Calibrate dual optical pickup sensors against certified laser tachometer to verify precise shaft rotational speed logging.
-
ShaPoLi (Shaft Power Limitation) Power Limiter Interlock Audit
Audit electronic power limiter lock box, verify tamper-evident seals, and test acoustic alarm threshold at MCR limit.
-
Data Logger Telegram Export & Class Compliance Report
Extract voyage telemetry data; issue Class-approved Calibration Certificate compliant with statutory EEXI technical files.
