Enerpac Takes the Load for Lamprell Jack-Up Rig
High-pressure hydraulics specialist, Enerpac, with its official distributor Al Masaood Trading, Dubai, has supplied Lamprell with an EVO-Series Synchronous Lifting System to weigh a newly completed jack-up rig.
The Enerpac multifunctional synchronous lifting EVO system monitors and manages lifting, lowering, weighing, alignment and load transfer procedures of non-uniform distributed heavy loads. The jack up rig cantilever and drill floor substructure weighing system comprised a 12 point synchronous EVO weighing system, two 600t hydraulic jacks, four 200t hydraulic jacks and accessories. Al Masaood Trading supplied the EVO system to Lamprell within 4 weeks to meet tight project timescales.
Compact Weighing System
A key benefit of the EVO weighing system is its compactness. Space restrictions under the jack-up rig prevented the use of other weighing systems without costly rework to the load structure. To make the Enerpac jack design even more compact the weighing system used calibrated high pressure transducers in place of load cells.
Enerpac’s synchronous lifting technology monitored the position and load of each jack-up rig lifting position, comparing it with a global datum and adjusting to the desired target position – movements are safely and efficiently managed, within permissible load and synchronous stroke tolerance parameters, preset to suit the project.
Unprecedented Weighing Accuracy
During the jack-up cantilever and drill floor substructure weighing, the accuracy of the lifting synchronization was such that the difference in plunger stroke of each of the cylinder was less than 1mm, enabling an unprecedented level of weighing accuracy for this type of project.
