Sea barge (V6)
Methane and ethane transfer on Kraken Mare
Methane and ethane transfer on Kraken Mare. Marine hardware on a methane sea: electric screws, cryogenic hoses and ISO 14726 pipe colours. Barges load liquid hydrocarbons at the jetty and carry them along the coast.
Propulsion: Electric screw drive. Envelope: 42 m long by 11 m maximum diameter design · beam; draft about 4 m
