On Thin Ice
Date of Completion
Capital dredging of Sabetta Port as part of the construction of an LNG plant and export terminal by Yamal LNG (a joint venture led by Novatek, including Total, CNPC & China’s Silk Road Fund).
What happens when you have a working window of only 10 weeks to dredge 10,500,000 cubic metres of soil and permafrost at Sabetta Port in the Russian Ob Bay before the route back unapologetically freezes back over? 18 vessels awaited the all-ice-clear in Murmansk, the world’s largest ice-free port north of the Arctic Circle, before being escorted along the Northern Sea Route to start their mission. An extension of time was not on the table.
Sabetta’s success began with robust planning, dynamic scheduling, resource levelling and scenario-based risk tracking. These measures minimised idle time, optimised cost and maximised productivity across a critical, time-bound campaign.
Effective integrated risk management was another key to success. Risks ranged from permafrost dredging dynamics and ice conditions to supply chain bottlenecks and interruptions by LNG module deliveries. All risks were successfully handled by predictive analytics, scenario-based planning and real-time monitoring.
Every seasonal campaign provided the necessary data to tweak methods, predict bottlenecks and refine vessel mobilisation plans for the next year’s window. These adaptive solutions integrating lessons learned, feedback loops, process optimization and training programs further optimised operations in one of the world’s most demanding environments.
