We can do nothing about the LNG prices,
but we can have a huge impact on the infrastructure cost

LNG bunkering ships has so far been unachievable due to cost and not at all scalable. This is one of the main reasons why ports and infrastructure providers have not invested in ships and thereby making ship owners hesitating to build LNG ready ships. The Kanfer solution is far more flexible, cost competitive and scalable. You could start with a self-propelled ATB barge only that will be able to maneuver inside a port without a tug. When demand increase or bunkering to take part outside port limitations, a tug could be added. Then you can add a number of barges and tugs according to the demand.
