DSIC’s super large tanker fitted with carbon fiber sails completed a sea trial
The 308,000-ton crude oil tanker n°100 built by DSIC, a subsidiary of China State Shipbuilding Corporation (CSSC), for China Merchants Energy Shipping Company, successfully completed a nautical test. The ship is equipped with a second-generation sail device, which is a model of a new generation of energy-saving and consumption-reducing ships, according to DSIC.
The ship is equipped with two pairs of rigid airfoil sails. The sails are independently developed by DSIC in cooperation with China Merchants Energy Shipping Company, China Shipbuilding 702, Dalian Maritime University, Dalian University of Technology and other Chinese scientific units.
The sail blade structure is the first to use carbon fiber composite material, which has the characteristics of light weight, high strength and high resistance to marine environment. The autonomous intelligent control system significantly improves the adaptability of the sails to the complex operating conditions of the ship as well as the sail operation efficiency, DSIC details.
The installation period of the four sets of sails is only 15 days, and the debugging period of the control system is 20 days. More than 400 alarm points of the sail system have been submitted for inspection, ensuring that the trial nodes are realized on schedule.
The sail performance verification has undergone low-level and sail-raising optimization tests. The actual ship’s fuel consumption has been significantly reduced, and the energy-saving and project development goals for engineering applications have been achieved.
This trial cycle completed all the inspection projects in 7 days, realizing an important step of the scientific research project of “engineering application of airfoil sail booster system”.
