CoreMarine, Jumbo Offshore Collaborate on Argentina FLNG Installation & Hook-up Project Maritime Activity Reports, Inc. April 13, 2026 © Jumbo Offshore CoreMarine & Jumbo Offshore have announced the award of a significant contract to perform the transport and installation of the soft-yoke (SSY) mooring systems, and hook-up of both the Hilli Episeyo FLNG and MKII FLNG vessels, in Argentina’s Golfo San Matías. The award represents a milestone for both companies as well as a breakthrough project for Argentina’s gas sector as it ramps up in export capabilities. The contract has been awarded by Southern Energy S.A. (SESA), supported by an international consortium comprising Pan American Energy, YPF, Pampa Energía, Harbour Energy, and Golar LNG.  Integrated Project Delivery CoreMarine and Jumbo Offshore will deliver the project through a fully integrated execution model that combines project management engineering, transportation, offshore installations and hook-up. As lead contractor, CoreMarine will contract Jumbo Offshore to transport and install the SSY mooring system including heavy lift and piling activities. Jumbo Offshore are the leading global experts in soft-yoke installations and have extensive experience with such systems in Brazil and Cameroon. CoreMarine will follow-up with diving and construction activities including spool installation, ballasting, riser hook-up, pre-commissioning, positioning and hook-up of both FLNG units. The offshore campaign will involve complex, simultaneous operations including heavy lifting, riser installation, piling, spool installation, saturation diving, and multi-vessel SIMOPS. The project will require the chartering of multiple assets including DSV’s, support vessels and station keeping tugs. The SSY systems, supplied by NOV, will enable both FLNG units to weathervane around a single mooring point, aligning with environmental forces and providing a robust, cost-efficient solution that eliminates the need for fixed
