Gearbox redesign and delivery - QSGTL
Qatar Shell GTL (QSGTL) faced several failing gearboxes in a critical part of the Pearl Gas-to-Liquids (GTL) plant. A peak load of 63.9kN-m was experienced during start-up and the existing gearboxes had a 44.5kN-m threshold.
Shell invited Stork for an in-depth engineering study into the failing gearboxes, following Stork Oryx Turbo Machinery Services’ successful participation in major turnarounds for Shell in 2015 and 2016.
The engineering study, executed by Stork Gears in Rotterdam, identified the gear sets could be redesigned to enable the gears to withstand a minimum peak load of 65kN-m during startup. This resulted in Shell awarding Stork a three-year contract for the delivery of 100 redesigned gear sets (see image right) for the GTL plant.
This integrated way of working is an excellent example of how Stork improves asset reliability and performance, while working with its Clients to find optimal solutions to all challenges.
Stork’s solution will deliver improved asset reliability without large and expensive asset modifications.
Stork’s offer was impressive and delivered a better price per unit.
Stork shared it’s knowledge and expertise with Shell’s engineers to improve the existing gearboxes.
