Rigging Inspection Services

As we are starting 2018, don’t forget to inspect all Rigging and Lifting Equipment to make sure that it is ready for another year of service. You can perform these periodic rigging inspections at any time of the year, but it is important to understand that users are required by ASME standards to perform a periodic inspection of all of your slings and hardware at least once a year.  

Bishop Lifting’s Services Department is available to come to your location and perform rigging inspection services. If you are interested in having Bishop’s Services department perform a periodic inspection on your rigging equipment contact them at 713-674-2266 or services@lifting.com.  Our team can help you develop an inspection schedule that best suits your company's needs.  Sometimes due to severity of use, periodic inspections can be required to be performed monthly, quarterly or annually. 

You are not required to use a third party for your periodic rigging inspections, and can use any of your employees that consider to be qualified based on experience and training. If you do not feel that you have any employees that are qualified, Bishop Lifting also offers training on rigging gear inspection. We offer many training options from 1 hour presentations all the way up to 2 day Rigging Inspector courses. The length of the training and the scheduling can be customized to meet your needs and your schedule. For more information contact our training department at 713-674-2266 or training@lifting.com.

Block Repair & Refurbishing from BLP Services

auxilliary-block-vesselBLP Services team took on a huge refurbishing job on a 400te main deck crane auxiliary block on a multi-purpose, deepwater pipe lay and heavy lift vessel.  This 400te working load limit (WLL) hook block is an auxiliary block on one of the three cranes on-board designed to support heavy lift, pipelay and subsea installations. Crane blocks require frequent inspections daily, periodic inspections quarterly to annually depending on use, and a complete disassembly and thorough inspection service every 5 years.

Our service technicians started with a complete inspection of the duplex hook and attachments checking for deformation, cracks, gouges, and thread wear.  They then checked the latches on either side of the hook for proper function. The sheave wheels were inspected for misalignment, or wobble, and wear, and the proper positioning of sheave pin nuts. The rope grooves were checked for normal wear from use or for abnormal wear from misuse such as using improperly sized wire rope. This block is designed to be used with 2-3/4" diameter wire rope. All nuts, bolts, pins, and other hardware were double checked to make sure they were still installed and that they didn't show any signs of bending. The side plates, pins and axles, fittings and trunions were checked for signs of cracking and deformation. The block assembly was completely disassembled and any damaged or missing parts were repaired or replaced.  

The refurbishing process included: 

  • Pre and Post Non-destructive testing (NDT)
  • Blasting to remove all old paint
  • All bearings and seals were replaced with new
  • DNV witnessed, 110% overload pull tested (986,000 lbs.)
  • Re-painted and tagged
  • Full certification pack
