Houston, May 15 (Reporter Xu Jianmei) The municipal authority of Galveston, an island city in eastern Texas, said on the 15th that a barge hit a local bridge that day, causing a fuel leak and damage to the bridge.

The bridge involved was the only land route to Pelican Island north of Galveston. David Flores, head of bridge affairs for the Galveston County Navigation District, said that due to strong water and high waves, a tugboat from Texas International Port lost control of two refueling barges it was driving, one of which hit the bridge pillar.

Aerial footage showed that part of the bridge pillars collapsed, and large pieces of broken concrete and rail fragments hung on one side of the bridge and fell onto the barge.

After the accident, the bridge, which was opened in 1960, was closed. Galveston City Authority said in a statement that no injuries had been reported. The accident caused a fuel leak in the Gulf of Mexico, and the U.S. Coast Guard will determine the extent of the leak and initiate control and cleanup procedures.

Galveston County spokesman Spencer Lewis said the barge could carry 30,000 gallons of oil (about 113.55 million liters). It was unclear how much leaked into the bay. About 105 kilometers of waterways around the incident were closed.

Texas A & M University at Galveston on Pelican Island said the accident caused a brief power outage at the school and power has now been restored.

According to US media reports, American ship collisions with bridges have occurred frequently in the past few months. On March 26, a container cargo ship crashed into a bridge in Baltimore, Maryland, in the eastern United States and collapsed, killing six people. On April 12 and 13 on the Ohio River near Pittsburgh, Pennsylvania, 26 inland river barges separated from their moorings due to floods and drifted uncontrollably, when one hit a bridge that had been closed. On May 9, a large barge broke loose from a tugboat on the Mississippi River flowing through Iowa and sank after hitting the nearly century-old Fort Madison Bridge.

According to Japan’s “Daily News” reported on March 19, Japan’s scallop exports have fallen into a difficult situation.

The report said that due to China’s long-term suspension of importing Japanese aquatic products, Japanese scallops are facing a difficult situation. Despite the efforts of the government and aquatic industry operators to expand export markets, Hokkaido, which accounts for 80% of Japan’s scallop production, has nowhere to export.

We plan to send Japanese companies to your country to inspect new scallop processing sites and hope to get the support of the minister. On March 1, Japanese Minister of Agriculture, Forestry and Fisheries Tetsuki Sakamoto raised the above hopes when he met with Mexican Minister of Agriculture and Rural Development Villalobos, who was on a visit.

The Japanese government is also looking for opportunities in Southeast Asia. In addition to exploring the possibility of establishing scallop processing sites in Vietnam and other countries, on February 19, Tetsushi Sakamoto also invited ambassadors to Japan from six ASEAN countries including Thailand to visit Toyosu Market in Jiangdong District, Tokyo to vigorously promote Japanese scallops.

Japan’s Ministry of Agriculture, Forestry and Fisheries stated that China has previously been Japan’s largest export destination of aquatic products, and scallop exports to China ranked first among all categories with 48.9 billion yen in 2022. Nearly half (1.43 million tons) of Japanese scallops exported overseas are sold to China. Among the 960,000 tons of shelled frozen scallops, 30,000 to 40,000 tons are processed in China and then exported to the United States.

However, in 2023, affected by the discharge of Japan’s nuclear-treated water into the sea, China dropped to third place in Japan’s aquatic products exports, and scallop exports to China dropped sharply by 44%. Even if Japan wants to process its own exports, it is limited by a shortage of manpower, and the United States does not allow the import of scallops with shells, causing scallop exports to be in trouble.

However, setting up a separate scallop processing site is not easy. In January this year, when the Japan External Trade Organization led a number of Japanese companies to inspect factories in Vietnam, they encountered a practical problem: how to process scallops that Americans like. According to reports, Americans like to use scallops to make teppanyaki, and the scallops are roasted. The volume will shrink, and Chinese companies have developed special technology to make them smaller and still meet the needs of American consumers. But the technology of Japanese and Vietnamese companies is not yet up to it.

According to a report by the German News TV channel on March 14, a latest report released by the American Institute for War Studies stated that due to lack of ammunition and supplies, the Ukrainian defense line may be more fragile than the impression given by the relatively slow advancement of the Russian army in various places.

The report said that in order to curb the continued advancement of the Russian army, Ukraine currently has to use the small amount of existing materials as efficiently as possible. The Institute for War Studies wrote: The Ukrainian army concentrated its supplies in the areas of the line where the Russian army encountered the most fierce attack, which would lead to poor defense in other areas, allowing the Russian army to launch surprise attacks there and achieve breakthroughs.

The American think tank also quoted a report in the magazine Der Spiegel. A Ukraine officer said in a report that in secondary battlefields such as Kharkiv or Vukhredar, which are currently receiving little attention, the situation of troops, weapons and ammunition is very bad. An artillery commander said: We can’t hold on like this for long. The analysis report wrote that the reason why some Ukrainian troops were able to hold their positions with limited ammunition and supplies was only because the Russian army did not attack with all its strength.

The Institute for War Studies warned that the Russian army did not attack areas where Ukraine was extremely poorly guarded, concealing the risks there. In other words, as long as the Russian army launches large-scale attacks in these areas, it will expose the current situation that the Ukrainian army is unable to resist due to lack of ammunition. Ukraine’s Armed Forces Commander-in-Chief Sersky warned on a social platform telegram that Russian troops may break into the depths of the Ukrainian defense line.

The Institute for War Studies said the words of Sersky and other Ukrainian commanders suggested that if the Russian army stepped up its offensive, it could break through and shake previously stable areas in a short period of time.

The report concluded that the current defense line is likely to be unstable. It is crucial for the West to transfer resources to the Ukrainian army as soon as possible to prevent Russian troops from waiting for opportunities to break through weak defensive areas on the front line.
