Lack of properly assessed and defined wear limits for jacking systems can lead to significant downtimes with financial implications for jackup operations.
Global industry players in the jack-up industry and classification society DNV GL have established a joint industry project (JIP), to provide guidelines on determining relevant wear criteria for self-elevating units.
Wear Acceptance Criteria for Jacking Systems JIP
The "Wear acceptance criteria for jacking systems" JIP, is expected to begin early 2016 with eleven partners already confirmed. The JIP is building on a DNV GL Recommended Practice (RP) issued last year to address maintenance and inspection challenges of a jack-up system. It will document relevant design arguments, considerations and calculations to enable the industry to define acceptance criteria and develop guidance on the correct assessment of jacking systems in a RP.
