The study aims to support the post-pandemic recovery of the maritime industry, which has experienced a 43% reduction in passenger vessel operations due to COVID-19.
The Maritime Industry was hit hard by the COVID-19 Pandemic
Passenger transport around the world has been significantly impacted by the COVID-19 pandemic, with the limited time passengers spend together posing a risk to health and the spread of the virus.
Although research on how the virus spreads in hospitals and other settings such as cars is extensive, comparable studies on COVID-19 on board ships are limited.
The key findings, published in the journal Ocean Engineering, show that on-board airflow environments are unique because of their forward motion, and that the position of an opposite door can cause significant airflow to distribute. infected particles more widely.
The researchers conducted the study using a series of computational models to look at the airborne transmission of Covid-19 inside a ship.
They examined what happened when an infected person coughed or spoke when the door was open, and how the spread of this virus changed when the door was closed.
Closed doors and air conditioning equipment
Results from the research model show that the movement of virus particles is limited to a radius of half a meter, which is less than the width of a chair when the door is closed. The passenger’s seat can then be adjusted accordingly to account for this difference radius.
The researchers also looked at the effects of air conditioning devices and found that adjusting the direction of the downward airflow serves as a measure to limit the spread of the virus. “We were surprised by the results of the study because it differed from mainstream guidelines for fresh and healthy air. In the case of boats, it is clear that closing the ship’s front doors will minimize the spread of infection.“Dr. Luofeng Huang, lead author of the paper said.
Our next step is to continue our research to develop guidelines for fishing vessels, where the fishing process often requires more than 10 crew members to work in tandem and the physical demands make wearing a mask a challenge. unrealistic.
With this concern, hundreds of thousands of fishing vessels are still suspended, increasing the economic damage in the region.
