瓦锡兰发动机测试生物LNG燃料

据天然气加工网站4月9日报道 瓦锡兰正在与芬兰边防卫队合作，测试生物液化天然气作为海岸警卫队巡逻船的燃料。其目的是减少温室气体（GHG）的排放，从而减轻对全球变暖的影响，这艘96米长的船只“图尔瓦”号装有瓦锡兰双燃料发动机，自2014年下水以来，一直得到瓦锡兰维修协议的支持。生物液化天然气燃料由芬兰国有沼气提炼厂Gasum提供。

经过对Gasum提供的生物液化天然气燃料规范的仔细评估，瓦锡兰相信它代表了瓦锡兰发动机多燃料能力的可行燃料选择。在这一评估之后，芬兰边防部队选择继续进行测试方案。

边防卫队巡逻船队的战略是尽可能改用环境可持续的燃料。在“图尔瓦”测试生物液化天然气是实现这一战略的重要一步。

瓦锡兰海洋电力公司研发和工程部的Juha Kyt?l?表示：“瓦锡兰正在大力投资开发替代清洁燃料技术，以推动整个航运业的脱碳。我们已开发出与使用这种燃料相兼容的发动机技术。液化天然气已经被广泛接受为一种可行的海洋燃料，我们认为生物液化天然气是天然气的下一步。因此，我们非常支持这项测试计划。”

生物液化天然气是一种100%可再生燃料，与传统燃料相比，在其生命周期内可减少高达90%的二氧化碳排放，且不排放颗粒物（PM），几乎也不排放氮氧化物（NOx）和硫氧化物（SOx）。

Bio LNG fuel tested with W?rtsil? engines

W?rtsil? is cooperating with the Finnish Border Guard in the testing of Bio LNG as fuel for a Coastguard patrol vessel. The aim is to lower greenhouse gas (GHG) emissions, thereby lessening the impact on global warming. The 96 metre long vessel, the ‘Turva’, is fitted with W?rtsil? dual-fuel engines and has been supported with a W?rtsil? maintenance agreement since its launch in 2014. The Bio LNG fuel is supplied by Gasum, a Finnish state-owned biogas refiner.

After close evaluation of the Bio LNG fuel specifications provided by Gasum, W?rtsil? is confident that it represents a viable fuel choice for the multi-fuel capability of the W?rtsil? engines. Following this evaluation, the Finnish Border Guard opted to proceed with the testing programme.

“The strategy for the Border Guard’s fleet of patrol vessels is to switch to environmentally sustainable fuels wherever possible. Testing the Bio LNG in the ‘Turva’ is an important step forward in fulfilling this strategy,” says Commander Marko Aheristo from the Finnish Border Guard.

“W?rtsil? is investing heavily in the development of technology for alternative clean fuels that can drive decarbonisation throughout the shipping industry. We have developed our engine technology to be compatible with the use of such fuels. LNG is already broadly accepted as a viable marine fuel, and we see Bio LNG as a natural next step. We are, therefore, extremely supportive of this testing programme,” says Juha Kyt?l?, R&D and Engineering, W?rtsil? Marine Power.

Bio LNG is a 100 percent renewable fuel that can reduce CO2 emissions over its life cycle by up to 90 percent compared to conventional fuel. It emits no particulate matter (PM), and close to zero nitrogen oxides (NOx) and sulphur oxides (SOx).
