5. 5 Hoist and Gear Operations

6. Cranes and heavy material moving equipment are extremely important to the operations of ship breaking. 6 Figure 1 Crane hoisting line and vessels rigging

7. Without it shipbreaking would be extremely labor intensive and unsafe. 7 Figure 2 Hoisting sectional to shore via crane

8. But with the usage of the equipment comes safety concerns that can result in injury and death. 8 Figure 3 Exploration rig on barge awaiting to be dismantled

9. There are many components that go into hoisting operations which increases the chances for systems to fail. 9 Figure 4 Crane along side of slip hoisting

10. Before the hoist takes place check to ensure proper rigging and that the rigging is laid out safely. 10 Figure 5 Rigging properly laid out and trimmed evenly

11. The loads should never be moved over personnel. 11 Figure 6 20 ton Steel coils being off loaded

12. The supervisor, on the vessel, is initially in charge of the hoist and gives the crane operator the only crane signals. 12 Figure 7 Supervisor monitoring final cut before hoisting section

13. As the load is being put under tension keep clear of the rigging and material. 13 Figure 8 Load clearing side of vessel

14. Common mistakes are inadequate rigging and placement. 14 Figure 9 Workers securing rigging with gear

15. The connection of gear to the equipment is just as important as the load connection. 15 Figure 10 Crane conducting hoist off superstructure

16. The crane operator does not generally have a clear view of operations that are ongoing on the deck of the vessel. 16 Figure 11 Supervisor monitoring hoisting

17. Before the hoist, all personnel must be clear of the area and other equipment moved to a safe location. 17 Figure 12 Worker removing the rigging after hoist

18. Personnel can be caught between the hoist and that is why the supervisor must be accountable for all personnel. 18 Figure 13 Crane signalman giving directions to crane operator

19. During the hoist the on deck supervisor will monitor the hoist and give directions to the crane operator. 19 Figure 14 Crane operator at the controls awaiting for directions

20. The only time personnel are allowed to approach the hoist is at the direction of the on deck supervisor. 20 Figure 15 Crane moving into position for hoist

21. Shock loading the hoist is prohibited and dangerous to the load, equipment, and personnel in the area. 21 Figure 16 Crane hoisting section slowly

22. The transfer point when the hoist is clear of the vessel is when the crane operator takes charge of the hoist. 22 Figure 17 Crane moving section to bank

23. Workers are not allowed to ride the hoist at any time during the operations. 23 Figure 18 Section being hoisted to yard

24. 24 Inspections

25. The hoisting gear must be inspected regularly and prior to each use. 25 Figure 19 Double cranes along vessel

26. The inspection has to be completed during each shift change and frequent intervals during the operation. 26 Figure 20 Hoist suspended awaiting to be placed in the yard

27. Defective hoisting gear must be immediately reported to the supervisor and removed from service until repaired or replaced. 27 Figure 21 Close up view of chain and shackles

28. Verify the safe working load of the gear for operations that will take place during the shift. 28 Figure 22 Safe working load stenciled on spreader bar

37. 37 Hoisting Series

38. 38  The following photos are various materials that are being hoisted from the vessel to shore.  Discuss the operations and view points of the evolution.  The angle shown is generally what you do not observe.

53. 53 Emergency Situations

54. Overloading the crane and equipment is one of the most hazardous conditions. 54 Figure 42 External derrick barge moved into place to hoist

55. The crane and or rigging can fail resulting in the load dropping and causing crane instability. 55 Figure 43 Crane rigging inside cargo hold ready for hoist

56. Tipping results when the boom is extended beyond the limits and/or load weight exceeds equipment limitations. 56 Figure 44 Crane hoisting sectional to yard

57. A crane tipping over can result in injury to the operator and loss of equipment. 57 Figure 45 Crane swing section to yard

58. The supervisor should be fully alert for any conditions that would lead to tipping or overloading. 58 Figure 46 Supervisor monitoring hoist as it clears the vessel

59. Gear failure happens when the load exceeds the safe limits or inspection failed to find defects. 59 Figure 47 Supervisor giving crane signals to crane operator

60. During the initial hoist the material can snag or catch resulting in overloading or straining of the gear. 60 Figure 48 Personnel clearing area as section being hoisted

61. Once the hoist separates from the snag it can cause a snap back of the gear causing it to swing wildly or upward rapidly. 61 Figure 48 Front view of bridle on tension

62. Long reaches can have dramatic results in equipment and gear performance. 62 Figure 49 Crane making pull from right side of vessel

63. The longer the reach the less weight that can be hoisted. 63 Figure 50 Crane boom angle
