Many land-based LNG export projects seek ‘economies-of-scale’ to lower their costs by developing 10 – 20+ MTPA projects. By re-purposing existing offshore pipelines and building the FLNG Vessels at efficient, low-cost world-class shipyards, Delfin can achieve total capital costs around 500-550 $/ton(1) for just 3.5 MTPA FLNG Vessels. This puts the Delfin project at the bottom end of the cost curve and with lowest FID threshold.
With 4 FLNG vessel slots at the Delfin project for a total of 13 MTPA of LNG export and with up to 8 MTPA expansion potential with the Avocet project, Delfin offers large scale LNG production at the bottom-end of the cost curve
|Liquefier FLNGs||Existing Liquefier FLNGs have successfully operated and are proven examples of the lowest unit costs in the industry.|
|Asian Fabrication||Floating LNG Vessels are constructed at existing efficient shipyards using low-cost labour and efficient, experienced fabrication sites.|
|Brown-field development||Re-purposing of existing offshore pipelines. By reversing the flow these pipelines can service as feedgas supply lines for the Deepwater Port FLNG Vessels.|
|Shipyard fabrication||Shipyards have built a vast amount of facilities and infrastructure to construct vessels, topside modules and integrated them into a complete production facility. Leveraging that expertise offers lower costs and high comfort on cost, schedule and performance compared to a green field LNG plant which is stick-built on a new site along the coast.|
|FLNG – a compact, all-in-one solution||An FLNG Vessel is an inherently efficient and low cost solution due to the integrated design and common functionalities. For example, the hull provide the storage tanks, but also the support for the topside modules as well as acting as the berth for visiting LNG carriers. Power, heat and cooling systems are ingeniously designed as total energy systems to provide compact, low-cost and efficient design and operations. Integrating all systems and support functions on a compact FLNG significantly reduces the amount of cabling, piping, maintenance, utilities etc.|
|Asian ECA and vendor financing||By constructing our FLNG Vessels in Asia the project can receive favourable financing support from Export Credit Agencies that greatly enhances the project financing terms|
|No new onshore pipelines||Delfin’s existing offshore pipelines connect directly to the extensive network of onshore pipeline systems, with ample supply capacity for the first 2-3 FLNG Vessels. There is no need for new onshore pipelines.|
|No congestion at the Port of Shipping Channel||Being offshore the LNG carriers can swiftly position and tender Notice-Of-Readiness before being escorted by dedicated tugs to berth along an FLNGV. Time and costs for pilotage and channel navigation congestion and delays is avoided and the collision risk absolutely minimal.|
Our FLNG Vessels are “Liquefiers”. They are developed to receive pipeline quality gas to treat and liquefy into LNG. These FLNG Vessels can perform the same service in many other locations where pipeline quality gas is available. This gives our FLNG Vessels a high intrinsic value that enhances the commercial and financial structuring, an advantage that land-based LNG plant do not have. By standardising our design solutions on the Liquefier FLNG Vessels we can reduce costs and enhance operations and reliability. By building identical FLNG Vessels we can further reduce costs for subsequent vessels on our Delfin, Avocet and other North American projects.
FLNG Vessels that produce from reservoirs are more complex and bespoke and often called “LNG FPSOs”. These vessels are much more costly, specifically designed for a particular field and are less suitable for redeployment.
Our projects in the Gulf of Mexico are brownfield projects utilizing existing pipeline infrastructure by re-purposing its use. By creating a floating LNG export facility, Delfin LNG will eliminate the need to construct large onshore liquefaction, storage and marine jetty facilities, which can be disruptive to surrounding environments and populations. We are using air cooling technologies that will minimize the use of sea water for cooling processes and protect marine life in the project’s vicinity.
Furthermore we use best available technologies for an efficient overall system design to minimise fuel use and reduce the emissions.
The visiting LNG carriers will berth offshore for loading new parcels of LNG from the FLNG Vessels. These LNG carriers do not need navigate inshore of the Texas or Louisiana ship channels.
