Offshore Crane Safety #Rig_Inspection_Workshop Crane checklist (relevant for MODUs) : • Record the date of the last crane diesel engine overhaul. • Check the date of the last slewing brake test. • Ensure that the aircraft warning lights in the boom and A-frame are working (API Spec 2D appendix C). • Ensure a windsock is fitted. • Check the condition of the A-frame ladders. • Check the certification of the wires: boom, main and whip wire. • Check the date of the last load test (Classification Society, Lloyd’s Register, ABS, and DNV). • Check the last load test by Class (up to 20 tons: SWL plus 25%: from 20 to 50 tons: SWL plus 5 tons: above 50 tons: SWL plus 10%). • Ensure load cell management and radius/weight alarms are installed and working satisfactorily. • Verify that NDT inspections of the pedestal, crane boom and blocks are part of the lifting- gear surveys. • Verify that four-yearly NDT inspections of the slewing (bearing) bolts are carried out (internal and external). Some rig crews do 25% yearly. • Function-test the high limit switches of the main and whip line, and the high and low limit switches of the crane boom (API Spec 2D app C Section 4.1.2d). • Verify that only safety glass is used for the crane cabin windows (API Spec 2C Section 12.2). • Check the records of the last boom pin NDT inspections (API Spec 2D Appendix C). • Verify that the crane control handles return to the centre position when released (API Spec 2C Section 11.1.2). • Check the operation of the wire drum braking systems (API Spec 2C Section 8). • Verify that the friction brakes are fitted with rain guards (API Spec 2C Section 13.3). • Verify that the sheave sizes are no less than eighteen times the diameter of the wire rope (API Spec 2C Section 7.4.1.1). • Verify that there is a load chart in the crane cabin (API Spec 2C Section 4.2). • Verify that an emergency stop for the crane engine is available, that it is operated from the crane cabin and is in working condition. • Check the correct installation of wedge-type sockets, paying particular attention to the wire clamps (API Spec 2C Section 7.3.3). • Verify the land rig crane procedures: only allow lifting when the support legs are extended and secured. • Check that there is a procedure to ensure that land rig cranes are not allowed to move while there is a lift hanging in the crane. • Note some cranes are now built to lift and carry. • Land rig cranes require to follow the rules and requirements of the local authorities and the drilling contract.
