Pole top pins drive FLNG and SSY growth Argentina

National Oilwell Varco (NOV) has recently received a contract to provide the submerged swivel and yoke system (SSY) for Argentina’s inaugural FLNG project. SSY systems serve as a mooring and gas transfer mechanism that enables the FLNG vessel to remain secured. Southern Energy SA is leading the project, with partners that include Pan American Energy, YPF, Pampa Energia, Harbor Energy, and Golar LNG. The FLNG facility entails relocating the Hilli Episeyo vessel to generate approximately 2.4 million tonnes of LNG annually. The SSY system ensures secure docking and continuous gas transfer via an underwater pipeline. Gas from Vaca Muerta offers a pathway to export markets for Argentina’s gas reserves. Nonetheless, this progress encounters various obstacles, including infrastructure constraints, operational hazards, and pricing uncertainties.

Vaca Muerta gas production is crucial in expanding domestic gas production, consumption, and export. Both FLNG and SSY systems transfer massive loads from the mooring chains to the vessel structure. This ensures the vessel remains safely on station in harsh environments found offshore Argentina. Utility top pins provide reliable onshore power connection for FLNG or their supporting infrastructure. The massive floating facilities have significant power needs for their operations. Crossarm pins ensure the integrity of every connection in the grid for uninterrupted operations. The local medium-voltage distribution is part of the network that brings power to the substation. They are crucial components to ensure the reliability of the power pathway. Pole top pins ensure that the power lines are securely insulated from the pole structure.

Functions of pole top pins in FLNG and SSY systems

Pole top pins are supportive hardware used in power transmission and distribution networks to secure line insulators. They provide a stable interface between the insulator and the pole. It ensures electrical conductors remain elevated and aligned. Pole top pins ensure reliable electrical infrastructure that supports liquefied gas operations. The pins pair with instrumented insulators that track line currents, detect faults, and improve operational reliability. Here are the roles of pole top pins in the FLNG and SSY systems in Argentina.

1. Support for high-voltage insulators—pole top pins secure pin-type insulators, holding conductors in place. They help prevent electrical arcing and keep power lines isolated from the pole body.
2. Maintaining electrical clearance and safety—FLNG and SSY sites involve explosive atmospheres due to LNG vapors. Pole top pins keep conductors elevated and ensure minimum clearance from structures, equipment, and personnel.
3. Load distribution and mechanical stability—pole top pins transfer the mechanical stresses from insulators and conductors into the pole. They help prevent conductor snapping or sagging.
4. Reliable power for LNG operations—FLNG platforms need a continuous power supply for compressors, pumps, cryogenic storage, and control systems. Pole top pins help avoid outages that could disrupt LNG liquefaction.
5. Integration with smart grid monitoring—SSY yards integrate sensors and smart grid systems. Pole top pins help improve operational reliability in Argentina’s LNG infrastructure.

Technological advancements in FLNG and SSY system creation by NOV in Argentina.

The Vaca Muerta shale formation in Argentina offers plentiful shale gas for export prospects. NOV offers its underwater swivel and yoke system for offshore anchoring and gas transfer solutions. These technologies offer Argentina adaptable offshore berths, effective gas transfer, resilience, and intelligent monitoring to enhance operational uptime. These advancements encompass:

• Submerged swivel and yoke (SSY) system—this is an underwater mooring and swivel that enables the FLNG vessel to stay anchored while still being able to rotate. The yoke plate creates a structural link and stability between the vessel and the mooring foundation.
• Cutting-edge swivel technology—NOV’s swivels incorporate robust seals and bearings engineered for rotation at high pressure and flow rates. This aids in minimizing friction, lowering wear, and guaranteeing ongoing functionality without regular upkeep.
• Flexible and expandable mooring design—the SSY system is compatible with various vessel dimensions and LNG transfer rates. The NOV system enables growth without altering the mooring arrangement.
• Subsea integration and pipeline security—the SSY system features strong subsea connectors that connect Vaca Muerta gas pipelines to the FLNG unit. The design guarantees minimal bending stress and reliable load distribution to lower the chances of leaks.
