According to the Maritime Reporter & Engineering News, the Great Ships of 2022 has released, Shanghai Passenger Shipping' s Xin Sheng Tai and COSCO Shipping Energy Transportation' s Yuan Rui Yang are on the list.
M/V Xin Sheng Tai
M/V Xin Sheng Tai is the Zero-emission Supercapacitor, an electric ferry developed by Shanghai Merchant Ship Design & Research Institute (SDARI), built by Yaguang Technology Group.
M/V Xin Sheng Tai is intended for public transit between Changxing Island and Hengsha Island located at the Yangtze River estuary. It has capacity of 165 passengers and 30 cars (or 14 trucks) and will have 24 round trips a day. The 2km crossing takes about 6 minutes. The 625kWh Supercapacitor system of the ferry to be used as main electric power and propulsion power is designed for the ferry trip of such high frequency and short crossing, which can be charged at quay of Changxing via a DC fast-charging system of continuous charging power up to 2.5MW during boarding and loading period.With rapid charge-discharge rate, high power density and virtually unlimited life cycles, no replacement of the supercapacitor is needed due to life cycles. Accurate monitoring and control of the energy can be achieved as the supercapacitors have performance of liner charge and discharge voltage.
M/V Xin Sheng Tai is designed aiming on energy-saving, environment friendliness, safety and economy. Reduction of energy consumption was achieved by hull lines optimization by CFD calculation and verified by model test carried out in SSSRI, energy conversion efficiency of the supercapacitor system is above 95%. The estimated CO2 reduction is more than 1000t annually compare with the diesel driven ferry. With low internal resistance, supercapcitors are safer than battery and do not heat as much as battery when short circuited. In addition, 2 sets of diesel generator are installed on board only when emergency for the round trip between the quay of the island and typhoon shelter.

M/V Yuan Rui Yang
The world's first LNG dual-fuel VLCC them, Yuan Rui Yang, was delivered in February 2022 from Dalian Shipbuilding Industry Company (DSIC) for COSCO, classed by China Classification Society (CCS).
The Yuan Rui Yang will be operated by COSCO Shipping Energy Transportation and measures 333- x 60-m with a molded depth of 30.5 m. Using LNG as its main fuel, it is equipped with the dual-fuel engine, power generators and boiler. In gas mode, the ship's endurance can reach 12,000 nautical miles, with a combined endurance for fuel and gas of 24,000 nautical miles. It makes the design energy efficiency index (EEDI) about 39.3 percent lower than the baseline value.
CCS has further awarded class notations for the ship including Natural Gas Fuel, i-Ship(E) for ship intelligent energy efficiency, Green ShipⅠand NEC (Ⅲ) for NOx emission control. It is designed with the C-type storage tanks, which are two 3,500cbm LNG low-temperature storage tanks with completely independent intellectual property rights obtained for the vessel.
