The IGF Code provides industry standards for ships that use fuels with a flashpoint of less than 60°C. The IGF Code seeks to regulate the safety changes from the carriage and use of gas fuel, in particular liquefied natural gas and other low-flashpoint fuels. These fuels are used in engines such as a Marine LNG Engine.
Updates were adopted to the Code at MSC 93 in May 2014. [7] The Code was extensively updated on 1 January 2016 under IMO Resolution MSC.370(93). [8] Other recent amendments include: New ship and fire integrity arrangements, adopted in November 2016 and entered into force on 1 January 2020. These relate to window fire-rating requirements on gas ...
REC-90. Brighton, MI Sunoco Price sign advertising availability of Rec-90 Gasoline. REC-90 is an ethanol-free, 90 octane unleaded gasoline blend designed for use in recreational/marine engines which can be damaged by the ethanol found in other gasoline blends. It is also usable in some aviation engines [1] and automotive engines, though it has ...
An alternative to the steam turbine engine is the dual-fuel marine diesel engine. Commercial ship propulsion system manufacturers such as Finland's Wärtsilä and Germany's MAN Diesel are producing large bore dual-fuel diesel engines. The MAN B&W ME-GI Engines have extremely flexible fuel modes that range from 95% natural gas to 100% HFO and ...
Induced gas flotation (IGF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by injecting gas bubbles into the water or wastewater in a flotation tank or basin. The small bubbles adhere to the suspended matter causing the suspended matter ...
The calculated ignition index (CII), together with the calculated carbon aromaticity index (CCAI), are empirical indicators which describe the characteristics or properties of a fuel. [ 1] Both CII and CCAI are calculated from the density and kinematic viscosity of the fuel. CII was developed by BP to calculate the autoignition capacity of ...
Brake-specific fuel consumption. Brake-specific fuel consumption (BSFC) is a measure of the fuel efficiency of any prime mover that burns fuel and produces rotational, or shaft power. It is typically used for comparing the efficiency of internal combustion engines with a shaft output. It is the rate of fuel consumption divided by the power ...
Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (newtons, or N), hence thrust-specific. This figure is inversely proportional to specific impulse, which is the amount of thrust produced per unit ...
