PETROBRAS Crisis
About 90% of investment
Federal prosecutors discovered a
bribery scheme and corruption
Public administration, contractors and Directors involved
Stock price melted
23 companies suspended for new contracts
1st Barrier
Wire rope culture
Successful past experiences
Behavior well know by designers
and operators (feel safe to use)
Easy to buy (local or import)
Consolidated standards and guides
Good over-sheave fatigue resistance
Heat and cut tolerant

2nd Barrier
Misconceptions about fiber ropes (believe or not)
UV radiation: can be a problem for some fibre and small diameters. HMPE
fibers are unaffected.
Not as strong as steel wire: high-performance fibers (HMPE) are size-for-size as strong as wire rope, at less than 15% of the weight.
Susceptible to cutting and abrasion damage: can withstand considerable abrasion and unacceptable level of
damage can be identified in inspection.

3rd Barrier
Technology
Standards and guides consolidation: Definition of factors of safety.
Deployment of full load & recovery of empty hook
Low stiffness of rope: load elongation & increased natural period
More sensible than steel wire: heat, abrasion and cut damages
Requires adequate handling and handling system.
Low coefficient of friction
Transverse cut resistance

Not to damage the load, wear your sling, or else, use fibre rope!!!
