The first liquefied natural gas (LNG) vessel constructed by Hudong Zhonghua Shipbuilding (Group) Co., Ltd. has successfully completed its sea trials, marking a significant milestone in the company’s shipbuilding capabilities. Key components, including the self-developed cargo tank insulation box structural parts, have passed rigorous testing and met all technical specifications. It is expected that the vessel will be delivered by the end of this year.
The construction of the LNG carrier began on December 15, 2004, and the trial phase officially started last month on the 21st. During the initial sea trial, the ship underwent a series of critical tests, including the magnetic compass adjustment, main engine reduction gear meshing inspection, remote control system testing, power failure simulation, speed measurement, emergency stop at full speed, swing test, endurance test, and unmanned cabin verification. Among these, the emergency stop at high speed and the reverse test were particularly challenging due to their high technical demands. Thanks to meticulous preparation from all parties involved, the equipment and control systems performed flawlessly, and the two consecutive successful test runs were completed without any issues. All trial activities were finalized by the afternoon of the 28th.
The shipowner expressed great satisfaction with the performance during the trials and sent a message of appreciation to the project team. Following the routine sea trials, the next steps will include low-temperature loading and unloading system tests, gas handling procedures, and clearance measurements. To ensure the smooth execution of these tasks, Hudong Zhonghua has developed a comprehensive plan, covering manpower allocation, scheduling, quality assurance, and safety management. This detailed approach reflects the company’s commitment to excellence and its growing expertise in building advanced LNG vessels.
Spray Dryer
Liquid material is pumped into the top installed centrifugal disc atomizer by mono pump and atomized into fine droplets inside the drying chamber. Meanwhile, clean hot air is blown into the air distributor at the same time. The evenly and swirly distributed hot air completely contacts with droplets for heat transfer. The droplets are dried into powder in several seconds and sucked out into the cyclone for discharging via exhaust fan.
LPG series spray dryer has been widely used in health products, chemical, feedstuff, ceramics, plastic and foodstuff industry for drying liquid material into fine powder.
