Sener Launches LNG Bunkering Vessel Design

Spanish engineering and construction company Sener has developed its own design of a Liquefied Natural Gas (LNG) bunkering vessel.

The Sener design follows the tendencies for 2030 required by operators and ship-owners.

The result is a Ship To Ship (STS) LNG bunkering vessel, with IMO type C LNG cargo tanks at 4,5 bar and -163ºC, which reduces to a minimum the steam generated in the tanks (BOG – Boil Off Generated). A BOG management system has been incorporated, to process the BOG generated in the transfer process.

This storage system allows greater flexibility of operation, reducing the effect of the wave inside the tank, sloshing, thus allowing partial loads, the designer explained.

The vessel is designed for navigation, maneuverability and operation in adverse meteorological conditions, including unrestricted navigation notation.

The propulsion uses LNG as fuel, with type C tanks on deck.

The main particulars of the prototype are:

Overall length……………………………………………..114.8 m
Moulded breadth…………………………………………20.4 m
Moulded depth…………………………………………….8.5 m
Draught……………………………………………………….5.7 m
Speed…………………………………………………………..15 kn
Capacity……………………………………………………….8000 m3
Number of tanks……………………………………………2
