On June 28, 2021, China’s first 174,000 cubic meter floating liquefied natural gas storage and regasification unit (LNG-FSRU) independently developed and built by Hudong Zhonghua, a subsidiary of China State Shipbuilding Corporation, was named " The TRANSGAS POWER" sign marks another major breakthrough made by China State Shipbuilding Corporation in the field of high-end marine equipment R&D, design and construction, and China's liquefied natural gas (LNG) entire industry chain genealogy has added weight.

"TRANSGAS POWER" is the first ship of two series of ships tailored for the Greek DYNAGAS company. CSSC Leasing provides financing services. Hudong Zhonghua adopts the design concept of "green, environmental protection, low carbon, safety" and the most complete and optimal equipment configuration, endows it with many highlights such as good reliability, versatility, forward-looking and economical efficiency, and its comprehensive performance has reached the international advanced Level.

Strong versatility, providing one-stop solution

This type of ship integrates all the functions of a traditional LNG carrier and a traditional land-based receiving station, and has the functions of LNG transportation, receiving, storage and regasification. As an LNG ship, its hull line type incorporates the most advanced multi-objective optimization design concept, with a design speed of up to 19.5 knots, which is comparable to the current mainstream LNG carrier, and its hull size fully considers the compatibility of more than 100 major LNG shore stations around the world Sex, can reach the whole world. As a FSRU, this type of ship can be applied to sea areas with various temperatures, and the regasification export capacity can reach 4 million tons per year. It is a veritable one-stop solution for the transportation of offshore natural gas from liquid to gaseous pipeline network.

High reliability, can be normalized for continuous low temperature operation

Compared with the traditional LNG carrier, the low-temperature system of this ship will operate normally in FSRU mode, which can carry out 24-hour uninterrupted operation for many years, and deliver gaseous natural gas to the land pipeline network steadily and continuously. At the same time, the working conditions of parallel operation in the FSRU mode are much more complicated than those of LNG ships. There are complex working conditions in which liquid tank loading and unloading, empty tank shutdown and maintenance, and regasification and export are carried out simultaneously. Flash steam treatment system and regasification and export. The control of the system is very complicated. The important systems of the device adopt redundant design, such as the configuration of 4 main generators, dual-engine and double-propeller propulsion system, 3 gasification chains, and reserved space for the 4th gasification chain. The main electromechanical and cargo system designs meet the single point of failure mode (FMEA) design requirements as required to ensure that the entire ship's system can still operate safely and stably in the case of a single point of failure.

Good environmental protection and broad market prospects

The design of the ship is forward-looking, and the dual-fuel electric propulsion system greatly improves the comfort of the crew and enables the EEDI to reach the third stage of the standard ahead of time. The dual-fuel generators and dual-fuel regasification boilers configured to operate in gas mode can meet the current most stringent IMO Tier III emission requirements. They are typical environmentally friendly ships with very strong market adaptability and Good market prospects.

 LNG-FSRU is a high-tech, high-value-added, and high-risk "three-high product". It is a special equipment integrating LNG receiving, storage, transshipment, gasification, and exporting functions. It is called a large-scale offshore LNG Shore station.

Its successful R&D and construction has enriched the genealogy of China's LNG industry chain and achieved synchronization with the latest equipment in the international market, demonstrating Hudong Zhonghua’s strong technical reserves and advanced equipment development capabilities in the international LNG industry chain equipment field, and firmly ranks among The first phalanx in the field of international LNG equipment manufacturing.
