Together with DNV Washington State Ferries (WSF) explores LNG as fuel

“WSF burns more than 17 million gallons of ultra-low sulfur diesel each year – and it’s our fastest growing operating expense. LNG has the potential to significantly reduce emissions and the cost of fuel,” said Washington State Department of Transportation (WSDOT) Assistant Secretary David Moseley.                   

LNG as a fuel is a promising, but new technology for WSF. To ensure that the safety, security and operational challenges of such a move is handled in a responsible manner, Washington State Ferries has partnered with DNV, a risk management company with extensive experience of LNG fuelled ships and the infrastructure they demand.

MV KALEETAN might be operated with LNG in the future

DNV has taken the leading role in making LNG as a fuel safe and viable. 35 out of 37 LNG fueled vessels in the world, including the very first in 2000, have been built to DNV’s standards. Of these, 16 are car/passenger ferries. Almost all of them are operating in Norway as Fjord crossing car/passenger ferries.  Particularly for short-sea shipping, LNG technology can make a big difference quickly, when it comes to reducing harmful emissions.

“As the biggest ferry operator in the US, and the third biggest in the world, WSF can really lead the way for its industry. In DNV, we can now clearly see a tipping point when it comes to global interest in LNG fuelled ships. Knowing that LNG as a fuel helps reducing emissions and costs, our team of researchers, engineers, and business analysts are looking forward to assist WSF and other companies with managing risks related to their LNG operations,” says Kenneth Vareide who is Director of DNV’s maritime operations in North America.

“I am pleased to have DNV aboard to assist Washington State Ferries in this important look at liquefied natural gas a possible fuel for the fleet, and look forward to these next steps that WSF will take with DNV,” said Washington State Department of Transportation (WSDOT) Assistant Secretary David Moseley.

Facts: Fueling vessels with LNG significantly reduces emissions:

• Approximately 100 percent reduction in particulate matter and sulfur oxides

• At least 80 percent reduction in nitrogen oxide

• Approximately 20 percent reduction in carbon dioxide
