Aibel is responsible for the EPC delivery of the Munin topside for Aker BP's Yggdrasil development in the North Sea. Topsides construction has taken place at Aibel's yard in Haugesund, complemented by module and section deliveries from Aibel’s yard in Thailand.
Mammoet was contracted by Aibel in late 2023 to support the execution of critical heavy lift and marine activities for the Munin topsides, the most significant being site move of the Utility Module from Aibel’s fabrication site in Thailand to the nearby quayside, followed by load-out onto a Marine Transport Vessel for shipment to Haugesund; load-in of the Module and sections from the Marine Transport Vessel following its arrival in Haugesund and site move of the fully assembled Munin Topsides from the quayside in Haugesund, and load-out onto the transportation barge prior to sailaway from Haugesund.
Operations in Thailand and Haugesund were complex and required careful planning and execution. Mammoet mobilized highly specialized equipment and personnel in Thailand and Haugesund, and executed a complex transshipment operation in Haugesund, where shallow water conditions at the quayside necessitated transfer to a smaller barge before load-in to the quayside, and subsequent site move inside Aibel's assembly hall.
Challenging winter weather and demanding positioning tolerances for final installation and mating of the Utility module with the Munin process module in Aibel’s assembly hall presented significant operational challenges that were successfully managed by both Aibel and Mammoet.
In July, the completed topside was weighed and prepared for load-out. Following confirmation of its final weight and centre of gravity, the topside was successfully loaded out onto the Topsides transportation Barge, a Class 1 operation, performed within a narrow tidal window that once again required meticulous planning and coordination.
Close collaboration between Aibel and Mammoet has been a key contributor to the successful execution of these activities.
Through the provision of specialized equipment, technical expertise and experienced personnel, Mammoet has contributed to Aibel’s safe and successful delivery of the Munin topsides that is now ready for offshore sailaway from Haugesund.
