Is it safe for the crew to work at sea?

Modern ocean-going ships are huge ships with a displacement of 10,000 tons or even hundreds of thousands of tons, with advanced equipment and scientific management. Depending on the electronic chart to determine the course, using GPS satellite positioning, full radar navigation, sonar detection, weather forecast, etc., it can be said that the safety factor of ships is higher than that of land vehicles. Sailing pilots and engineers must be technical personnel trained by maritime colleges, especially senior technical crew members such as captains, who have rich navigation experience. In addition, they can contact the relevant units on land at any time through maritime satellite communication, and the safety on board has realized the international safety management system with global unified standards according to regulations, so the current navigation work is very safe.
