On July 6, 2009, the world's first commercial single compressed natural gas (CNG) fueled ship, M.V. NP Jenjosh—the first of 12 contracted vessels built in Dajiang and Hongyu shipyards located in Wuhu city of Anhui Province, P.R. China and classed to China Classification Society (CCS)—was delivered to the owner, Jenjosh Group based in Thailand. This paper contains some technical discussions that took place during the class plan review of the subject vessels, including: hull technical practices, machinery, and electrical technical practices, and also discusses designing the similar CNG fueled ships and developing the international gas-fueled (IGF) ship code in future. Finally, this paper draws conclusions and looks forward to the future practice of the CNG fueled ship.

A model-based study is carried out based on a combination of mathematical and Maxwell models to develop a high-performance electric pressure regulator utilized for compressed-natural-gas-fueled vehicles. To reduce computational cost, a symmetric two-direction model of the electric pressure regulator is established in Maxwell software, in which its material properties and dimension parameters are obtained on the base of specifications of a real electric pressure regulator. The output of simulating in Maxwell is the electromagnetic force, which is significantly improved when changing core shape in the various dimensions ∆1, ∆2, and ∆3. The optimal electromagnetic force is utilized for the mathematical models as an input variable to simulate the operational characteristics of the electric pressure regulator such as displacement and response time of plunger. The operational characteristics of the electric pressure regulator are examined under the influences of key parameters, including inlet gas pressure, diameter of orifice, and spring stiffness. By optimizing these key parameters, the simulated results in this study show that an electric pressure regulator with high performance can be obtained.

Performance And Emissions

In the present work, an attempt has been made for the effective utilization of Compressed Natural Gas (CNG) in diesel engine. A four stroke, single cylinder diesel engine was modified to work on dual fuel mode. The effect of CNG flow rate and Exhaust Gas Recirclulation (EGR) on the performance and emissions of the dual fuel engine was studied. The variables considered for the tests were different CNG flow rates (0.2, 0.3, 0.4, 0.5, 0.6 and 0.7 kg/hr), EGR (0 %, 4.28 %, 6.63 % and 8.12 %) and loads (25 %, 50 %, 75 % and 100 % of full load). From the test results, it was observed that the EGR rate of 4.28 % results in better brake thermal efficiency and lower CO and NOx emissions than other ERG rates at 25 %, 50% and 75% of full loads. At full load, EGR rate of 8.12 % results in higher brake thermal efficiency and lower NOx emissions.
