Saya mau bertanya mengenai safety pada sebuah rope / longline cabel. Spesifikasi rope yang digunakan adalah : Amsteel – Blue. AmSteel Blue is the latest development of HMPE fiber in a twelve-strand braided rope utilizing Parallay design with our proprietary blue Samthane urethane coating. This twelve-strand braided rope yields the maximum in strength-to-weight ratio and is stronger than wire rope constructions — yet it floats. It also has the best flex-fatigue and wear resistance when compared to products made of HMPE or post-drawn HMPE fibers. Specific Gravity: .98 (Floats). Dari manual retirement & inspection yang saya lampirkan dibawah, itu tidak membahas yang namanya Proof Load Test. hanya sebatas visual inspection saja. apakah Proof Load Test tersebut masih tetap diperlukan untuk rope tersebut ? dan metode yang digunakan seperti apa ? dan apakah ada di standar OGP ? mohon masukannya.

Dear Rekan Milis,

Saya mau bertanya mengenai safety pada sebuah rope / longline cabel. Spesifikasi rope yang digunakan adalah :

Amsteel – Blue

AmSteel Blue is the latest development of HMPE fiber in a twelve-strand braided rope utilizing Parallay design with our proprietary blue Samthane urethane coating. This twelve-strand braided rope yields the maximum in strength-to-weight ratio and is stronger than wire rope constructions — yet it floats. It also has the best flex-fatigue and wear resistance when compared to products made of HMPE or post-drawn HMPE fibers. Specific Gravity: .98 (Floats).

Dari manual retirement & inspection yang saya lampirkan dibawah, itu tidak membahas yang namanya Proof Load Test. hanya sebatas visual inspection saja. apakah Proof Load Test tersebut masih tetap diperlukan untuk rope tersebut ? dan metode yang digunakan seperti apa ? dan apakah ada di standar OGP ? mohon masukannya.

Long Lines: Retirement & Inspections

Retirement

RETIRE THE ROPE FROM USE WHEN IT HAS REACHED ITS DISCARD POINT.

One of the most frequently asked questions is ‘When should I retire my rope?’ The most obvious answer is before it breaks. But, without a thorough understanding of how to inspect it and knowing the load history, you are left making an educated guess.

Unfortunately, there are no definitive rules or industry guidelines to establish when a rope should be retired because there are so many variables that affect rope strength. Factors like load history, bending radius, abrasion, chemical exposure or some combination of those factors, make retirement decisions difficult.

Inspecting your rope should be a continuous process of observation before, during and after each use. In synthetic fibre rope the amount of strength loss due to abrasion and/or flexing is directly related to the amount of broken fibre in the rope’s cross section. After each use, look and feel along every inch of the rope length inspecting for damage as listed below.
