Offshore Crane Proof Load Testing

Offshore cranes of all types can be load tested using water bags. These cranes are typically used in the oil and gas industry. Hydro-Wates has extensive experience with offshore crane proof load testing services of the following types of offshore cranes:

  • Knuckle Boom Cranes
  • Lattice Boom Cargo Cranes
  • Provision Cranes
  • Engine Room and Workshop Cranes
  • Derrick Barge Cranes
  • Deepwater Service Vessel Cranes
  • General Use Deck Cranes

The use of Hydro-Wates water bags and certified load indicating equipment ensures compliance with regulatory and certifying authority requirements for periodic proof-load testing of these machines. We can provide certification of proof-load test results to internationally recognized standards specified by Det Norske Veritas – Germanischer Lloyd (DNV-GL), American Bureau of Shipping (ABS), Bureau Veritas, Lloyds Register, and others.

Knuckle Boom Cranes

The use of water bags for knuckle boom crane load testing is recognized as a safe technique for slowly applying the test load. This allows technical problems with the crane to be recognized and corrected prior reaching the full test load. In addition, load water can be drained without have to lower the test weight. This would be helpful in situations where the hoisting system or brakes were compromised in some way.

Hydro-Wates can also provide custom designed rigging arrangements using company owned high capacity load cells, spreader beams, slings and shackles. We stock this equipment in-house to enable rapid mobilization to your job-site. Our load cells are re-calibrated annually to ensure the measured loading on your crane is reported accurately. In addition, our load cells are sufficiently accurate to allow for calibration of your crane’s load indicating system. This is normally performed by staging up the test load to several calibration points, thereby enhancing the accuracy of the measured load once the crane is returned to service.

General Cargo Cranes

Rigging and equipment configurations for specific projects are reviewed and approved by one or more certified professionals to ensure test objectives are achieved.

In addition to providing personnel to perform onsite rig-up and filling of water bags, we also perform a comprehensive range of technical and specialized services, including:

  • Certification of proof load test results to nationally and internationally recognized standards specified by API, OSHA, ASME, NSTE, IMO and others.
  • Supervision of field work by qualified experts.
  • Rigging design and certification.
  • Specification of rigging components.
  • Fluid pumping using high capacity gasoline, diesel, air or electrically powered pumps.
  • Custom-designed lifting beams.
