Project description

Truck-to-Ship (TTS) LNG bunkering has been a largely adopted method for the initial LNG bunkering implementation. With ships having a small to moderate demand for LNG, of a few hundred cubic meters, TTS has provided for a flexible option, responding to a limited demand. Experience has been gained in procedures and operation with added value to the safe adoption of LNG as fuel.

LNG bunkering TTS operations are carried out from typically standardised LNG trucks (of around 40 to 80m3). With an increasing need for LNG, especially by ships with increased LNG fuel capacity, more than one truck may be required to bunker a single ship, depending on the required bunker volume. This may be achieved either in a sequential manner or, alternatively, through a common bunkering manifold.

Sofregaz is currently working on a study for LNG Multi-Trucks to Ship (MTTS) Transfer. The aim of this study will be to define a “scope of requirements” / “specification” for Multi-trucks to ship transfer of LNG to be attached to call for tenders. The main purpose is to specify the system that shall be used by companies in charge of the truck-to-ship operation in line with safety & HSE principles.

The main tasks to be performed for this study are the definition of a safety concept and definition of a dedicated specification for a skid allowing the transfer of LNG from multiple trucks to a ship.

After completion of this study, an additional study will be performed, related to a full conceptual and basis of design for a Multi-Truck to Ship (MTTS) Bunkering Skid.
