Argentina is developing its first floating liquefied natural gas facility, fed by gas from the Vaca Muerta shale formation. National Oilwell Varco (NOV) is supplying the submerged swivel and yoke (SSY) system. This system allows the FLNG to safely rotate with wind and currents while transferring gas through subsea pipelines. It also reduces the need for large fixed jetties or onshore LNG plants. This development uses various technologies such as subsea pipeline tie-in, mooring durability, and digital monitoring. FLNG and SSY infrastructure create a direct route to monetize gas reserves in the global markets. This creates job opportunities in engineering, logistics, shipping, and offshore services. Supporting such areas reduces Argentina’s trade deficit and attracts foreign direct investments. FLNG production also helps improve energy security for importing countries. B-strand connectors connect the high-strength spiral strand mooring line to the chain on the seabed or directly to the turret.
The strand connector ensures the integrity of the entire mooring system in the harsh environment offshore Argentina. B-strand connectors link the wire rope and other components. The connector stops the end of the wire rope and transfers the immense tensile load from the rope into the connector body without causing a failure. It helps reduce stress concentrations at the end of the wire. B-strand connectors are designed to be robust and provide a sealed termination that protects the end of the wire from corrosion. It provides a standardized, strong interface to connect to other mooring components. B-strand connectors work with high-performance spiral strand roles. It ensures a perfectly matched system with a proven fatigue life.
Significance of B-strand connectors in FLNG and SSY infrastructure
B-strand connectors play a crucial role in ensuring safety, reliability, and structural integrity for FLNG and SSY infrastructure. The connectors ensure the FLNG’s continuous operation to enable Argentina to export gas efficiently. B-strand connectors reduce offshore interventions to improve durability and reliability. The link from the connection provides load-bearing stability, ensures flexibility, and maintains electrical and structural continuity. Here are the roles of the B-strand connectors in FLNG and SSY infrastructure in Argentina.
- Structural load transfer in mooring systems—B-strand connectors link individual steel strands that make up the mooring cables. They ensure uniform load transfer across all strands to distribute tension and prevent weak points.
- Flexibility and adaptability in offshore conditions—the B-strand connectors provide flexibility to infrastructure. This allows mooring lines and subsea cables to adjust to vessel movement without overstressing the infrastructure.
- Electrical and signal continuity—the connectors work with subsea power and control cables that support SSY operations. They ensure the continuous transmission of electrical signals and monitoring data.
- Integration with SSY and pipeline systems—B-strand connector ensures secure attachment points for subsea pipelines, swivels, and yokes. It supports the stability of the gas transfer line to maintain both mechanical strength and alignment.
- Corrosion resistance in marine environments—the connectors can withstand saltwater exposure, pressure variations, and subsea chemical interactions. The durability extends the operational lifespan of mooring and subsea systems.
- Safety and redundancy—B-strand connectors create redundant pathways to ensure the connection remains intact. This prevents equipment failure that can lead to production halts or environmental risks.
Opportunities of FLNG development in Argentina’s energy sector
Despite Vaca Muerta’s shale formation, infrastructure and export limitations have restricted Argentina’s ability to monetize the resource. The development of FLNG technology creates a new pathway for growth, investment, and global energy integration. The successful management of FLNG could position the country as a leader in LNG export. The key opportunities in Argentina include
- Unlocking LNG exports without onshore terminals—FLNG bypasses traditional LNG development by liquefying gas directly offshore. Anchoring to the SSY allows Argentina to track exports.
- Monetizing Vaca Muerta gas at scale—Argentina can export gas directly from pipelines to global LNG carriers.
- Global energy markets—the FLNG exports provide flexibility and mobility to allow exports to reach many regions, depending on demand.
- Supporting energy transition—Argentina can leverage LNG revenues to fund renewable energy projects such as solar and wind. FLNG has a smaller carbon footprint compared to onshore LNG plants.
- Infrastructure flexibility and risk reduction—FLNG is scalable and relocatable to reduce investment risks compared to fixed terminals. Argentina can adapt capacity without locking into massive costs.
