On July 2, the anchor chain of the floating crane "Fujing 001" during the construction of the offshore wind farm project was broken while avoiding the typhoon "Xianba" at the anti-typhoon anchorage in the waters near Yangjiang, Guangdong. After that, the hull broke into two pieces and sank.
As of yesterday (4th), 4 people have been rescued in the accident, and the mainland search and rescue team has recovered the remains of 12 suspected victims, and relevant departments are stepping up their identity confirmation.
The internal media "China Ship News" reported that the "Fujing 001" has undergone many transformations before and after, but the anchor chain has not been replaced, and the old model of anchor chain is still used.

"Fujing 001" is affiliated to Shanghai Huajing Zhiyun Marine Technology Co., Ltd. "Fujing 001" was previously involved in the construction of the main engineering projects of YUDEAN Yangjiang Qingzhou I and Qingzhou II offshore wind power projects.
According to the report, the "Fujing 001" was previously a second-hand ship purchased by a port machinery company and changed to a transport ship. After the use of the ship, the ship was eliminated and then sold to Huajing Zhiyun.
Subsequently, the vessel was converted into a floating crane at a shipyard in Jiangsu, and a crane was installed.
Regarding the accident, the report quoted an industry executive as questioning: Why did not all the crew on board evacuated in time knowing that the typhoon was coming?
Even if it is too late to evacuate the ship, people on board should be evacuated in advance.
Second, it is an extremely rare accident that the hull breaks in two. Is there a design flaw in the ship?
Is the hull strong enough?
Is the shell plate badly corroded?
Third, does the anchoring and anchor chain breakage indicate that the mooring system design is flawed?
Is there a problem of ignoring the safety and reliability of the mooring system because of the hard-to-find benefits of wind power installation ships?
Not equipped with high-strength offshore chain
In response to the strength of the anchor chain, the industry executive also said that if high-strength anchor chains, such as R5 and R6 anchor chains, will have a greater chance of delaying the accident.
According to the report, the "Fujing 001" ship uses M3-87MM marine anchor chains made in Japan, not high-strength offshore (ocean engineering) chains. Preliminary judgments show that this type of anchor chain is relatively old. Although the ship has been refitted many times, But the anchor chain was not replaced.
The report quoted people in the industry who believed that the "Fujing 001" was originally a transport ship, and it was understandable that it was equipped with ordinary marine anchor chains. However, when it was later transformed into an offshore wind power construction ship, it should be equipped with high-strength offshore mooring anchor chains with reference to marine engineering standards. , in order to meet the basic anti-typhoon requirements.
Although the cause of the accident is not yet clear, it is certain that the ship's mooring system has no small hidden dangers.
The report also quoted industry sources as saying that with the rise of the offshore wind power industry in recent years, various sources of capital have poured in, and some old offshore equipment refitted halfway has been rushed into battle, which is very likely to lead to safety accidents, although it is still unclear. However, the problems existing in the field of offshore wind power equipment renovation are worthy of vigilance and reflection by industry enterprises and regulatory authorities.
