  3. Objectives • Identify operation procedures for cranes and derricks • Describe personnel platform systems • List testing and inspection procedures • Explain the operations of personnel platforms

  4. OSHA has guidelines on personnel hoist platforms. Figure 1 Personnel hoist in fishing vessel outriggers

  5. Personnel hoists should be the last resort when all other avenues such as ladders, scaffolds, and other means are exhausted. Figure 2 Crane along vessel as it enters the slip

  6. Employee safety should not be compromised for the operation. Figure 3 Personnel Lift on superstructure

  7. Cranes pose a risk of tipping and therefore must be on a firm level ground. Figure 4 Crane on level ground hoisting

  8. A 1% uniform grade must be maintained. Figure 5 Crane on level firm surface

  9. Minimum safety factor of seven for the load line of wire rope and ten for rotation-resistant rope. Figure 6 Hoist bridle with screw pin shackles attached

  10. Brakes or locking devices on the crane must be engaged when personnel are working aloft. Figure 7 Crane at rest between operations

  11. The platform must be rated for 5 times the safe working load of the intended lift. Figure 8 Load testing crane and rigging

  12. Install a suspension system on the top of the platform to prevent tipping. Figure 9 Personnel platform over side of ship conducting hot work operations

  13. Must have a rail to keep personnel from falling out including a toe board. Figure 10 Personnel platform with enclosed railing for worker

  14. Load placard is prominently posted on the platform with the load weight and platform weight. Figure 11 Worker inside platform conducting hot work on hull

  15. Do not exceed the platform’s rated load capacity. Figure 12 Overview of slip with crane hoisting a personnel platform

  16. Bridles and rigging dedicated to personnel hoisting can not be used for any other purpose. Figure 13 Personnel hoist on main deck of vessel

  17. Hooks and other attachments must be closed type to prevent opening. Figure 14 Closed hook

  18. Mousing the hook is strictly prohibited. Figure 15 Mousing hook with line

  19. A trial lift must be made before workers can be placed in the platform. Figure 16 Personnel hoist initial hoist tested

  20. A lift starts at ground level and is then positioned to the vessel. Figure 17 Supervisor monitoring movement of personnel platform hoisting

  21. All systems will be evaluated and inspected for safety concerns. Figure 18 Personnel platform over side of vessel static

  22. When the position shifts along the vessel a trial test must be completed at the new location. Figure 19 Crane along slip stationary

  23. Immediately after the trial lift conduct a complete inspection of the rigging, platform, and crane. Figure 20 Supervisors concluding inspection of equipment

  24. Before personnel can be transported in the platform, the lift has to have all kinks and twist removed from the rigging. Figure 21 Rigging being laid out

  25. The platform will be hoisted a few inches above the ground to allow the rigging to settle and check for alignment. Figure 22 Hoist in suspension above ground

  26. A competent person must conduct an inspection and test prior to usage. Figure 23 Close up of wire rope and rust within the lays of the strands

  27. Prior to the platform coming to the site a 5 minute proof testing, at 125% of the load capacity,must be completed. Figure 24 Certified weights for personnel platform hoist

  28. Tag lines are advisable unless they create a unsafe condition or be fouled in the rigging of the vessel. Figure 25 Rigging clear of vessel gear on main deck

  29. Personnel shall keep all body parts and equipment inside the platform at all times. Figure 26 Workers preparing to board

  30. Personal fall arrest systems must be attached to the lower back and to the platform. Figure 27 Personnel fall protection in place and secured

  31. The crane should not be in motion with personnel in the platform. Figure 28 Crane is on standby along slip

  32. If the crane must move with personnel, it must be restricted in the distance moved and a trial run should be considered. Figur29 View of the crane down the side

  33. Crane operator must be at the controls at all times when the machinery is operating. Figure 30 Supervisor monitoring operations over side of vessel

  34. Action Discussion What is the importance of a trial run of the platform prior to hoisting personnel?

  35. Action Discussion What are the duties of the crane operator?
