Testing of large diameter ropes for offshore lifting operations
The challenges of testing large diameter wire ropes
Some failure modes
A technique for testing large diameter wire ropes
Dr. Ronen Ashkenazi presented some test results of 8 strand IWRC ropes 40 mm, intalled in heavy duty grab cranes. Filure mechanisms for specific rope design were presented. Issues with regard to safety and discard criterial were emphasized during the presentation.
A large diameter testing machine for the testing of large diameter ropes under bending and fluctiating tension was presented.

Cranes today 28 July 2011
Title: Picking the right rope
" MRE Matron Rope and Wire Rope Engineering, an Israeli firm, has developed a test to show how a specific crane might be fatiguing its rope with the aim of improving rope life "

O.I.P.E.E.C conference 2009
Innovative Ropes and Rope Applications, A celebration of 175 years of wire rope
"Over 2 days a total of 22 presentation on rope science, technology, safety, and inspection were presented. The topics ranged from the history of rope (Weiss and Ridge), high performance roundslings (St. Germain), synthetic ropes under traction fatigue (Ashkenazi), swaged fitting under tension and fatigue (Raupp), over discard investigation of wire rope used in a gold mine (Rebel) to a finite element approach for rope modeling (Usabiaga/Durville).
