Would be floating LNG project developer Delfin Midstream will need to submit an updated version of its application to own, built and operate an FLNG-based project off the US Gulf coast after making many alterations to the planned development, US authorities have ruled.

The US Department of Transportation’s Maritime Administration (MARAD) said in a letter filed to the chief executive of subsidiary Delfin LNG, Dudley Poston, that it no longer supports its 2017 decision to issue a licence for the company to own, construct and operate a deepwater port.
