Bird of the Ocean” … the longest sailing cargo ship in the world  

A Swedish design company has unveiled a new concept for a cargo ship with gigantic collapsible “sails”, which it says can reduce emissions by 90%, according to the British “Daily Mail”. 

The vessel, dubbed “Ocean Bird” or “Ocean Bird”, is 200 meters in length and can transport 7,000 cars at an average speed of 10 knots. 

It is scheduled that “Ocean Bird” will take about 12 days to cross the Atlantic Ocean, which is a little longer than the current cargo ships, which operate on fossil fuels, but are distinguished by specifications that exceed international standards to preserve the environment. 

Designers at Wallenius Marine in Stockholm successfully completed sea trials of a six-meter prototype, in preparation for the construction of the real ship 200 meters long and 40 meters wide. 

Heavy cargo and long distances 

Wallenius Marine says the global shipping community needs to switch from fossil fuels to renewable energy to help combat the drivers of climate change. 

The Swedish company explains that the new ship, which will be the largest sailing ship in the world, could make a big change in the world of the maritime industry and prove in practice that zero-emission shipping operations are possible using the wind, explaining that the ship “Ocean Bird” can replace the large ships designed to transport Heavy cargo for long distances. 

Wind instead of fuel 

Shipping plays a central function in global trade and accounts for about 90% of all cargo transported, but it also contributes to emissions, so it is crucial to rely on sustainable energy in shipping operations. 

“Wind is the most interesting source of energy for ocean transport operations,” said Per Tonnell, Chief Operating Officer at Wallenius Marine, “The Ocean Bird, which has been fitted with an 80-meter-high winged sails, is a giant step in the development of ocean-going cargo ships.” In the future.” 

The longest sails in the world 

“Ocean Bird” sails are made from a specific formulation of an alloy of metals that helps them reach the height of the sails currently found on the largest sailing ships in the world. 

The dizzying height of the sails is making the most of the wind energy possible while decisively reducing carbon emissions. The techniques used in the design of the ship “Ocean Bird” allow the possibility of pulling the long wing sails and reducing their height by about 60 meters, in order to add maneuverability and sail capabilities easily in various conditions as it will avoid colliding with any bridges in its tracks, in addition to controlling the amount of wind that is Exploited. 

The total height of the ship from the water line up is 105 meters, but with the sails fully lowered, it will be no more than 45 meters. The ship will be equipped with biogas engines, to enable it to maneuver in and out of the port and to boost wind power in emergency situations. 

It is expected that the manufacturing of the ship and the completion of all trials and tests will be completed before the end of 2021, and the first vessel will be delivered at the end of 2024. 

New international standards 

The new design is in line with standards set by the United Nations’ International Maritime Organization (IMO), which aim to reduce carbon dioxide emissions from international shipping by 40% by 2030. 

At the beginning of this year, IMO issued new rules aimed at reducing the amount of sulfur emitted from cargo ships in order to improve human health by reducing air pollution. The rules included cargo ships using fuel with a sulfur content of 0.5%, down from 3.5%, or installing devices that remove toxic pollutants, known as scrubbers. 

Under these rules, refiners and shipping companies are expected to spend billions of dollars in the coming years to take measures to ensure that fuels and engines comply with new international standards
