Global ship deliveries have been hit as yards in China struggle to get fully back to work as a result of the coronavirus outbreak, with one shipbuilder saying it could not deliver two vessels.

The coronavirus has caused chaos in Asia and beyond with flights suspended, businesses disrupted and entry restrictions imposed by governments trying to ward off its spread. The global shipping trade has also been hit.

China’s Jiangsu New Times Shipbuilding, which has an annual production capacity of 5 million deadweight tonnes (DWT), had issued a force majeure notice on two vessels to Bermuda-based cargo operator 2020 Bulkers, a spokesman said.

“Workers are still not coming back to their positions due to the coronavirus. It is not known when they will resume work and when the two vessels will be completed,” he added.

This confirmed a statement by 2020 Bulkers on Tuesday which said that two newcastlemax dry bulk vessels due to be delivered in April and May face possible construction delays.

China is one of the biggest shipbuilders and shipping sources say there have been delays to vessels already meant to have hit the water and other yards had declared force majeure.

“There is no real indication of when full production will resume,” one industry source said.

Chinese authorities have asked companies to put workers into quarantine for 14 days after returning from their home towns for the Lunar New Year holiday, which was extended by a week.

The China Association of National Shipbuilding (CANS), which represents shipbuilders, said in a statement it was “generally hard for the vessel makers to resume work and deliver vessels on time”.

Some of China’s shipbuilders were highly likely to be unable to deliver vessels before July 1, which increased the risk of not being able to fulfil their contracts, CANS said.

Shipping sources said the delays were also having an impact on the fitting of exhaust gas cleaning systems known as scrubbers, which are needed to enable ships to continue to use high sulphur fuel after tough new rules on emissions.

“Over 70% of vessels currently undergoing scrubber retrofitting are doing so in China. On that front, there are on-going delays at shipyards because workforces are depleted, taking vessels out of action,” Charles Chasty, research analyst with broker Affinity Shipping, said.

“China accounts for over 40% of all new buildings. So, beyond the on-going current issues, such as the depletion of the labour force, vessels currently under construction are being delayed. Some of these vessels may even slip into 2021,” Chasty told the Reuters Global Markets Forum.

CANS data showed that around 75% of workers had come back to work at key shipbuilding companies in the southeastern provinces of Fujian and Liaoning, but only around 62.5% workers had returned to Shanghai as of Monday.

However, shipbuilding companies at Guangdong, Shandong and Jiangsu, where New Times is located, were seeing workers “gradually” restart work, CANS said.

The world’s biggest wireless trade fair was thrown into doubt on Wednesday after more big tech companies and mobile carriers including Nokia, Vodafone and Deutsche Telekom pulled out over worries about the viral outbreak from China.

They’re the latest in a string of tech companies to pull out of the event scheduled for Feb. 24-27. Ericsson, Amazon, Sony, LG, Cisco and Intel have already decided not to attend.

Nokia said Wednesday it has decided to withdraw from Mobile World Congress in Barcelona, Spain “after a full assessment of the risks related to a fast-moving situation.” The Finnish telecom infrastructure company said “the health and well-being of employees was a primary focus” and that canceling its involvement was a “prudent decision.” HMD Global, a separate Finnish company that makes Nokia phones under license, also said it’s pulling out. So did German carrier Deutsche Telekom, which said it “wasn’t an easy decision for us.” Vodafone said it was dropping out “after careful consideration” while Britain’s BT said canceling was “the most responsible decision.” The departures of Nokia and Ericsson leave China’s Huawei, a major sponsor of the fair, as the only remaining major network gear maker still planning to attend.

Organizers sought to hold out against growing pressure to cancel Mobile World Congress, an annual tech extravaganza that had been expected to draw more than 100,000 visitors from about 200 countries, including 5,000-6,000 from China.
