natural gas (LNG) as a new, viable source of power for marine vessels, ? re protection for the unique hazards pre- sented by this fuel source, including protecting bunkering stations, gas valve areas, LNG tank spaces and machinery spaces must be addressed. There is a certain level of danger when transferring fuel, regardless of its form. A spill event is a concern when transferring fuel whether it is taking place on board a ship or dockside. Containment of materials at all times is im-portant from both an environmental and ? re protection standpoint. The difference between LNG and legacy fuels is that natural gas is a liquid when cooled and stored at atmospheric pressure, but a gas when warmer than -160 degrees Fahrenheit. Due to its changing properties, it is important to pre- vent LNG from igniting as it changes state from liquid to gas, which can occur as it is exposed to the relatively warm temperatures of a ships operating environment. Another potential danger of LNG is that it burns very clean (? ames can be invisible), making detection, especially in an open area, a challenge. Leak detection prior to ignition is criti- cal. Traditional fuels, such as diesel, can pose an issue if not properly contained and are subject to possible ignition if a static arc or an errant ignition source is present. LNG FIRE PROTECTION SOLUTIONS Tyco Marine Services offers a variety of products with dry chemical powder, the only agent approved for the pro- tection of LNG bunkering stations. A full product line that includes ABC agent, a multipurpose dry chemical agent used on Class A, B and C ? res, as well as Purple-K agent, or PKP, which offers some enhanced performance characteristics, provides an approach that addresses the needs of LNG bunkering stations. According to Tycos Pelletier, dry chemical agents also offer a variety of delivery solutions to help provide protec- tion to all bunkering areas.
