Subject: Marine Conversion to Natural Gas
(Posted on Aug 29, 2012 at 02:45PM by Media Manager)

The American Clean Skies Foundation has released a study on
how maritime vessels might be converted to natural gas.
CealDoctor Self-healing Treatments could provide the answer at significantly lower costs, and with extended benefits for the fleet operators.


The ACSF study “offers the first in-depth look at the challenges and prospects for converting U.S.-flagged marine vessels to liquefied natural gas.”

In short, “The maritime industry can follow the path of other transportation sectors, which have looked to natural gas to move goods instead of relying on more expensive (and dirtier) diesel fuel,” ACSF says.

“On the environmental front, the maritime industry is facing federal regulations to reduce emissions of nitrogen oxide, particulate matter and sulfur dioxide, which will require switching to ultra-low sulfur diesel,” states a study summary. “Low in sulfur, LNG can be used to comply with the regulations. Norwegian shipping fleets have been successfully operating on LNG for years.”

Acknowledged obstacles include the high cost of vessel conversion and the lack of LNG infrastructure, especially at marine ports.

“Conversion of vessels to LNG operation is expensive,” the study cautions. “It can cost up to $7 million to convert a medium-sized tug to operate on natural gas, almost $11 million to convert a large car and passenger ferry, and up to $24 million to convert a Great Lakes bulk carrier.

“Approximately one sixth of this cost relates to conversion of the vessel engines and the rest is for installation of LNG storage tanks and related safety systems and ship modifications.”
