Why Do Cargo Ships Sail In Groups?

The shipping industry is reintroducing sails as a way to decarbonize and reduce its carbon emissions. Wind-propelled ships are a key solution, but building new cargo ships is expensive. The industry is also in the process of transitioning to electric cargo vessels, with Michelin developing a new type of sail for cargo ships. A Cargill-chartered cargo ship fitted with giant steel sails has set out on its maiden voyage.

Redwing sails are designed to cut fuel consumption and shipping’s carbon footprint. The industry is estimated to be responsible for about 2.1% of global emissions. Winds of change, particularly triggered by new international commerce and climate pacts and policies, could push us towards a New Age of Sail, with the need for a planet-wide fleet. Ships will only sail together in convoys when necessary for safety or operations.

Cargo ships can be divided into eight groups, including feeder ships, general cargo vessels, container ships, gasoil tankers, and dry bulk ships. The wing sails are expected to generate an average fuel saving of up to 30% on new build vessels, thereby cutting shipping’s carbon footprint.

WindWings are expected to generate an average fuel saving of up to 30% on new build vessels, thereby cutting shipping’s carbon footprint. They stand 123ft tall and are built of the same material as the original sails.

Sails can reduce existing ships’ fuel consumption and greenhouse emissions by 10-20%, according to maritime experts. Ro-ro ships are the preferred project due to their flexibility of operation and relatively uncluttered decks.

Why do cargo ships just sit there?

Why are the boats sitting out there?. The reason a ship, most often foreign, anchors for hours or days outside the harbors comes down to two simple words: free parking.

The reasons a ship might need to be at anchor, however, are more varied.

Fees kick in once a vessel enters the harbor, according to Carol Carrasca, a freight forwarder who retired after more than 40 years organizing shipments of goods for Lakeshead Forwarding.

Among expenses tallied are U.S. pilots and tugs to guide the ship to dock, line handlers to tie it up and dockage fees that figure in 24-hour guard duty and dockside insurance. Costs such as for pilots and line handlers repeat each time a ship moves to a new location for layby or to load. In an article for the Duluth Seaway Port Authority’s North Star Port magazine, Carol wrote: “All told, this can total thousands of dollars that neither the owner of the ship nor the charterer will be willing to pay.”

Why can’t cargo ships use sails?

Sail technology faces several practical challenges on cargo ships, including cranes, wind direction constraints, crew training, stability and maintenance.

Most tests of sail technologies are on passenger or ro-ro ships because masts, aerofoils or rotors on deck will obstruct cranes. For widespread adoption across ship types, sail technologies need to work around this.

Traditional sailing ships can’t sail directly into the wind, but we expect modern cargo ships to keep to a schedule regardless of the weather. Sail technologies that work regardless of the wind direction have an advantage over those that are restricted to certain points of sail.

In the modern world, most merchant seafarers have no experience of sail handling; most people with experience under sail have no qualifications for cargo ships. While it’s always possible to train merchant crew to sail, training adds friction to technology adoption. This is where automated solutions have an advantage over those that demand high levels of crew intervention.

Why do ships sail under the Liberian flag?

Walk along the docks of any port and notice the abundance of ships that display, in bold white letters on the stern, the appellation “Monrovia.” That city is the capital of the West African nation of Liberia, which has been left, after 10 years of brutal civil war, with a barely functioning government. Yet a third of the world’s shipping tonnage carries the Liberian flag, some 1,900 vessels; most of those ships, as well as numerous ships flying the flags of nations other than Liberia, can trace their ownership back to a Liberian-registered front company. The Liberian registry was created in 1948, primarily as a means to offer U.S.-based ship owners a way to crew their vessels without being subject to U.S. labor and wage regulations and U.S. taxation. Today the body overseeing the Liberian flag is not the government of Liberia, but a private business based in Vienna, Virginia the Liberian International Ship and Corporate Registry (LISCR). The Liberian government charters LISCR to handle its shipping business; LISCR remits 35 to 40 percent of its profits back to the Liberian government. Indeed, LISCR, according to the United Nations, became one of the primary sources of hard currency for Liberia’s former president, Charles Taylor, who is now in exile in Nigeria and under U.N. indictment as a war criminal.

In addition to offering its flag, LISCR also offers a corporate registry an office in Monrovia where thousands of ship owners can legally incorporate their ships. But according to U.N. inspectors who visited 80 Broad Street in the fall of 2003, the corporate registry office contains little furniture and has been looted of all workable office equipment. Nevertheless, thousands of ship owners choose to establish the legal identity of their ships there because it provides them with anonymity and insulation from financial accountability.

The Liberian registry reduced registration fees in 2000. Tonnage tax, for example, declined 75 percent, to US$.10 per ton. The registry now advertises itself as “one of the least costly alternatives for vessel registration.” Registering a ship in Liberia costs between US$2,500 and US$11,900, depending on the size of the vessel. These initial registration fees are followed by a yearly tonnage tax and a flat rate charge of US$3,800 for ships larger than 14,000 tons. There are no requirements to disclose details as to the “beneficial ownership” of a vessel; this makes it possible for owners to use front companies to limit both their liability and their responsibility should something go wrong on board one of their ships. The registry is based in Virginia, but has offices worldwide, in New York, London, Zurich, Piraeus, Hong Kong, Tokyo and Monrovia.

Why are so many ships registered in Panama and Liberia?

Most merchant ships flying Panama’s flag belong to foreign owners wishing to avoid the stricter marine regulations imposed by their own countries.Panama operates what is known as an open registry. Its flag offers the advantages of easier registration (often online) and the ability to employ cheaper foreign labour. Furthermore the foreign owners pay no income taxes.

About 8,600 ships fly the Panamanian flag. By comparison, the US has around 3,400 registered vessels and China just over 3,700.

Under international law, every merchant ship must be registered with a country, known as its flag state.That country has jurisdiction over the vessel and is responsible for inspecting that it is safe to sail and to check on the crew’s working conditions.

Are 2 sails better than 1?

Yes, but no, a single but larger sail would be better aerodynamically. Without getting too much into the details every sail creates a turbulence in the airflow that will impair the performance of its neighboring sail. Splitting sail area into multiple sails can make a sense though for other reasons.

What is a ship with many sails called?

A full-rigged ship or fully rigged ship is a sailing vessel with a sail plan of three or more masts, all of them square-rigged. Such a vessel is said to have a ship rig or be ship-rigged, with each mast stepped in three segments: lower, top, and topgallant.

Other large, multi-masted sailing vessels may be regarded as “ships” while lacking one of the elements of a full-rigged ship, such as having one or more masts support only a fore-and-aft sail or a mast of only two segments.(bettersourceneeded)

The masts of a full-rigged ship, from bow to stern, are:

Why are so many ships flagged in Panama?

Ever since the United States encouraged Panama’s independence from Colombia and orchestrated the 1903 treaty that gave it the right to build and operate the Panama Canal, Panama has frequently been a convenient haven for U.S. businessmen. In 1922, the transfer of two passenger liners, the Reliance and the Resolute, from the U.S. to the Panamanian registry represented the first major step in the development of the flag of convenience system. Panama offered ship registration in a country free of burdensome laws and regulations found elsewhere. In this case, the passenger liner company wished to avoid the U.S. prohibition laws against serving alcohol on board.

The Panamanian registry, run from offices in New York, has grown steadily since then and now includes more than 6,000 ships. Ship registration generates approximately $255 million annually in revenue for the Panamanian government. Owners from Japan, Greece, China and South Korea claim 70 percent of Panama’s fleet.

In 2001, Panama’s registry made the mistake of selling a first officer’s certificate to the general secretary of the International Transport Workers’ Federation (ITF), David Cockroft, in spite of his having absolutely no seafaring experience. The ITF, an international federation of transport trade unions, is well-known for strongly opposing the flag of convenience system. “The laugh is on Panama,” said Cockroft, “whose controls are so lax that they hand out a vital document to the head of an organization that for 53 years has challenged the abuses permitted by flags of convenience states such as theirs. It’s like awarding a good conduct medal to Attila the Hun.”

How do cargo ships avoid pirates?

Below are a few examples of anti-piracy methods:Evasion. Evading pirates may sound simplistic but if a ship can avoid pirates, it will not be at risk of attack. … Water Hoses. … Foam. … Barbed Wire. … Armed Guards. … Sonic Weapons.

The economic cost of piracy is significant but the damage done to human life is incalculable. It is difficult to determine the specific costs of piracy, but fortunately, there are several methods available to help combat and deter piracy. As piracy continues to thrive, and attacks and kidnappings see a marked rise. It is understandable why crews and vessels continue to invest heavily in anti-piracy measures. There are multiple anti-piracy options available with varying degrees of success depending on the situation.

Evasion. Evading pirates may sound simplistic but if a ship can avoid pirates, it will not be at risk of attack. It is a simple and non-combative option but has its disadvantages. For example, the added cost of time and fuel can make it counter-productive for many, and therefore not a viable solution. However, for others making one-off journeys is an effective option.

Water Hoses. Water hoses are the most commonly used anti-piracy weapon and are certainly one of the simplest and cheapest solutions available. By targeting attackers with water hoses, crews can make boarding a ship impossible by creating slippery surfaces or pushing pirates from their boats.

Why are cargo ships not armed?

Insurance regulations wouldn’t allow crewmen to use the firearm either. These are merchant seamen not Marine infantry. So you are going to have to hire trained shooters that cost money but don’t do any work 99% of the time. Firearms aboard a ship are troublesome at customs.

What is the spanker on a sailing ship?

On a square rigged ship, the spanker is a gaff-rigged fore-and-aft sail set from, and aft of, the aftmost mast. Spankers are also called driver, jigger, and pusher sail.

On a schooner of four or more masts, the spanker is the sail on the mast nearest the stern.

The spanker is a small sail, but as it is so far aft of the balance point of the hull, it has strong leverage. When sheeted in, the spanker is important in driving the boat to a new tack.
