Triple-bank mooring: overcoming integration challenges

This development is particularly relevant in LNG operations, where the ability to share real-time data between vessels and shore facilities is critical. Emergency shutdown protocols, mooring load monitoring, and environmental data transmission all rely on uninterrupted communication. The inability of different systems to exchange information in the past resulted in operational inefficiencies and potential safety risks. The introduction of adaptable ship-to-shore communication solutions has changed this dynamic, enabling LNG carriers, FSRUs, and terminals to operate as a unified system, regardless of the origin of their individual components. "That is our power as well, the flexibility to integrate with third-party existing systems," Mr Bains noted. Ship-to-Shore Link

One of the solutions in this space is the SafeCom SSL, a system designed to facilitate secure and reliable communication during LNG transfers. SafeCom SSL is capable of transmitting emergency shutdown signals and mooring load data to vessels, ensuring that crews have access to real-time information necessary for decision-making. The system adheres to international safety and performance standards, including ISO 28460 and SIGTTO guidelines, allowing it to be deployed across a broad range of existing LNG infrastructure.

The development of SafeCom SSL has demonstrated that true interoperability is achievable. While many manufacturers maintain that their systems must be used exclusively with proprietary components, recent projects have shown that this is not the case. Mr Bains noted that in some instances, third-party suppliers insist that their mooring hooks are required for effective communication, yet experience has proven that alternative configurations can be successfully implemented without sacrificing functionality. This flexibility is particularly important for LNG operators seeking to modernise their facilities without completely overhauling their existing infrastructure.

The ability to integrate third-party systems is not just a matter of convenience but a fundamental requirement for improving efficiency in LNG transfer operations. At the Wilhelmshaven LNG terminal, for example, mooring line monitoring data was successfully transmitted over an SSL system not supplied by Straatman. This validated the principle that disparate systems could work in concert, providing a template for future projects looking to adopt a similar approach. "We successfully communicated our MLM data over their SSL system to the ship," Mr Bains said, demonstrating how the system’s flexibility ensured effective data communication and operational efficiency.

Ship-to-shore communication is only one part of the broader equation. The success of triple-bank mooring also depends on advanced mooring equipment that can withstand the demands of simultaneous LNG transfers. Quick release mooring hooks (QRMH) play a central role in this, allowing operators to manage mooring lines safely and efficiently. The integration of load monitoring systems within these hooks provides real-time tension data, which can be shared via the SSL, ensuring that any excessive loads are identified and addressed before they become critical.

Berthing Aid Systems (BAS) and Environmental Monitoring Systems (EMS) play a crucial role in ensuring safe berthing operations. BAS utilises advanced laser and LED technology to measure the distance between the jetty and the approaching vessel, enabling precise and secure docking. It functions primarily as a berthing system for the vessel, rather than being involved in the LNG transfer process. Meanwhile, EMS provides real-time environmental data, such as wind speed, helping pilots and terminal operators make informed decisions for safe berthing.

Looking to the future, the adoption of triple-bank mooring is expected to expand as more terminals seek ways to increase capacity without large-scale infrastructure investments. The success of this method will depend on continued advancements in interoperability. Mr Bains suggested that ongoing developments in ship-to-shore communication would further improve integration capabilities, allowing for greater flexibility in LNG transfer operations.

While challenges remain, particularly in ensuring compatibility across a wide range of legacy systems, the industry has already taken a step forward. The shift away from closed proprietary systems towards adaptable, standardised solutions signals a change in how LNG terminals and vessel operators approach mooring and communication. "We prioritise using industry standards to ensure greater flexibility and ease of integration for our clients," Mr Bains said. The ability to integrate third-party components is no longer an aspirational goal but a practical reality, paving the way for safer and more efficient LNG operations worldwide.
