Liquefied Natural Gas, compared to conventional ship fuels, offers substantial reduction in NOX, SOX and particulates, but its costs are uncertain. Based on the study jointly made by Germanischer Lloyd and MAN Diesel & Turbo, this paper analyzes cost factors of LNG as fuel for container vessels and calculates cargo space losses resulting from LNG's low density. Calculation results show that cargo space losses are about 1.5%~2% of the total container volume. The results can be used as references for selecting LNG as ship fuel.

Various methods have been introduced to predict postweld hardness of the heat affected zone (HAZ) for 9% Ni steel which is a primary steel adopted in the construction of liquefied natural gas (LNG) storage facilities. Two models were derived for the evaluation of the HAZ hardness, and then validated. The formulae developed in this investigation are sufficient to predict the hardness of the HAZ for 9% Ni steel . For the model using a rule of mixture, it is suggested that the morphology of martensite should be taken into consideration. Since the prediction of hardness depends on the calculation of the critical cooling time and hardness of microstructural constituents, a formula to estimate the hardness of martensite in HAZ was given. For empirical equation relating welding parameters, calculation results were found to give a fairly good description of the postweld HAZ hardness.
