Connect LNG Sustainability

Frequently Asked Questions

Curious to know more? Here is a list of the most common questions we typically receive from customers who are starting out on their journey towards a jettyless future. If you still have other queries, don't hesitate to get in touch by clicking on "Contact Us", and we will get in touch shortly.

Can the UTS be used for both loading and unloading?

  • The UTS can be used for LNG transfer in both directions, and is suitable for loading, unloading or bunkering of LNG or other types of fluids.

What is the scope of delivery from Connect LNG?

  • Connect LNG will supply an EPC turn-key UTS solution with all utility and safety systems, including the flexible cryogenic floating hoses between the UTS platform and onshore facility. Connect LNG will also take EPC responsibility for the tie-in and onshore hose storage, control and monitoring of the UTS, and can also supply the mooring system for the LNG carrier and UTS.

What is the flow rate capacity of the system?

  • The standard UTS has a flow rate design of around 2,500 cbm/hr, but can be also designed for 50 - 1000 cbm/hr, which is typical for bunkering applications. A scaled version with capacity of up to 12.000 cbm/hr has also been developed for large-scale applications.

What is the lead time for the system?

  • Typically 9 - 18 months from contract award to first gas, depending on the site application. Qualified yards can build the platform once a sufficient level technical definition can be assured. Connect LNG's sourcing policy is to always investigate local supply chain capabilities for any new project.

What is the cost for the system?

  • The cost for the complete UTS system is highly dependant upon site location and operational requirements. It is necessary to look into the specifics of the project in order to understand what the necessary technical characteristics needs to be. In general, the UTS reduces investment by at least 50% compared to a traditional jetty or quay infrastructure.

What is special with the flexible floating cryogenic hoses?

  • The flexible floating cryogenic hoses will transfer the LNG between the platform and onshore installation. The hoses are highly robust and have excellent insulation capacity to minimize BOG development, and are equipped with a redundant integrated leak monitoring system. The hoses and UTS system will have similar BOG development as that during conventional loading/unloading.

Will the flexible cryogenic hoses require a reel onshore?

  • A reel can be installed to store the hoses between operations. The decision will be based on client preference and a site specific assessment. A solution without a reel is also feasible as the hoses are designed for continuous submersion in water.

What is the maximum weather conditions the system can handle?

  • The UTS platform has been developed to exceed the operating conditions of jetty-based transfer solutions. The limiting operating factors at a specific location are dependent on the combination of a number of parameters, such as joint occurrence and magnitude of wind, wave and currents, floating hose diameter, and distance from shore. However, it is often seen that the mooring of the LNG carrier will be the limiting factor. Connect LNG has proprietary software that can be used to calculate site specific performance of the complete floating solution.

How is the UTS connected to the LNGC ship side?

  • The UTS platform will connect to the ship side by the vacuum attachment system. The UTS is then able to connect to a large range and type of ships. The ship/carrier will be held in a fixed position by a Multi Buoy Mooring system.

How are the aerial hoses connected between between the ship and UTS?

  • The aerial hoses will be located onboard the UTS, and these are lifted by the ship's crane to the manifold where they are connected manually by ship's crew with a standard bolted flange connection. On the UTS platform, these same hoses are connected to ERC couplings. In an ESD 2 event, the aerial hoses will be released from the UTS platform at the ERC connection.

What is the safety philosophy of the system?

  • The UTS has been designed and built to meet the highest industry safety standards. There is a Ship-to-Shore Link (SSL) between the ship and UTS which automatically communicates ESD events to shore and to each other.

Is the UTS unmanned during operation?

  • For any LNG transfer operation, the UTS is unmanned, controlled and monitored remotely from a control station onshore. The operator located onshore has full overview of process flow parameters and status of main systems onboard.

How is the UTS supplied with power and control?

  • The UTS has a normal power consumption of only ~50 kW during normal operation, and receives power through a floating umbilical from onshore. The umbilical also feeds fibre optical signals for remote control and monitoring of the platform from the onshore control station.

Is the UTS certified and classed?

  • The entire UTS system has undergone a complete review by DNV GL, Norconsult, and the Norwegian Directorate for Civil Protection among others. The system complies with SIGTTO, OCIMF, EN 1474-2. The UTS is classed according to DNVGL-OS-E403 Offshore Loading Units.
