41-684: On 23 March 2021, while traveling from Tanjung Pelepas in Malaysia to Rotterdam in the Netherlands , the ship ran aground in the Suez Canal , blocking the channel. She remained in place for six days before salvage crews freed her on 29 March 2021. The vessel was impounded by the Egyptian government on 13 April 2021 for refusing to pay a reported $ 916 million in fees demanded by the government, including $ 300 million in "loss of reputation". The compensation claim

82-406: A large fixed-pitch propeller . The 11-cylinder straight engine , license-manufactured Mitsui MAN B&W 11G95ME-C9, produces 59,300 kW (79,500 horsepower) at 79 rpm and gives the vessel a service speed of 22.8 knots (42.2 km/h; 26.2 mph). In addition, Ever Given has four straight-8 Yanmar 8EY33LW auxiliary diesel generators that produce electricity. For maneuvering in ports,

123-445: A minimum horsepower or bollard pull, determined by the size of the escorted vessel. Most ports will have a number of tugs that are used for other purposes than ship assist, such as dredging operations, bunkering ships, transferring liquid products between berths, and cargo ops. These tugs may also be used for ship assist as needed. Modern ship assist tugs are "omni directional tugs" that employ propellers that can rotate 360 degrees without

164-665: A port in Hamburg. On a weekend in May, eight tugboats perform choreographed movements for about an hour to the tunes of waltz and other sorts of dance music. The Tugboat Roundup is a gathering of tugboats and other vessels in celebration of maritime industry. The Waterford Tugboat Roundup is held in the late summer at the confluence of the Hudson and Mohawk Rivers in Waterford, New York. The tugs featured are river tugs and other tugs re-purposed to serve on

205-409: A rudder, like azimuthal stern drives (ASD), azimuthal tractor drives (ATD), Rotor tugs (RT) or cycloidal drives (VSP)(as described below). River tugs are also referred to as towboats or pushboats. Their hull designs would make open ocean operations dangerous. River tugs usually do not have any significant hawser or winch. Their hulls feature a flat front or bow to line up with the rectangular stern of

246-448: A sandstorm had affected the area on the day of the grounding, with winds gusting as much as 50 kilometres per hour (31 mph). Addressing a press conference on 27 March, Admiral Osama Rabie, chairman of the SCA, said that weather conditions were "not the main reasons" for the ship's grounding, adding, "There may have been technical or human errors ... All of these factors will become apparent in

287-475: A supply chain delay, and tension due to the delay for the ships trapped as well as other vessels that planned to cross the Suez. Eight tugboats worked to re-float the vessel in collaboration with excavators removing sand from the side of the canal where the bow of the vessel was wedged. After an overnight break, the salvage work resumed in the morning of 25 March. Egyptian meteorologists reported that high winds and

328-513: Is Evergreen's second ship to be named Ever Given ; the first one ( IMO 8320901 ) was built in 1986 and has since been broken up . With a length overall of 399.94 metres (1,312 ft 2 in), Ever Given is one of the longest ships in service. The hull has a beam of 58.8 metres (192 ft 11 in) and her height from keel to main deck (hull depth) is 32.9 metres (107 ft 11 in). Fully laden at design draught , Ever Given draws 14.5 metres (47 ft 7 in) of water while

369-862: Is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbors or narrow canals , or cannot move at all, such as barges , disabled ships, log rafts , or oil platforms . Some are ocean-going, and some are icebreakers or salvage tugs . Early models were powered by steam engines , which were later superseded by diesel engines . Many have deluge gun water jets, which help in firefighting , especially in harbours. Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: Compared with seagoing tugboats, harbour tugboats that are employed exclusively as ship assist vessels are generally smaller and their width-to-length ratio

410-670: Is a container port located in Gelang Patah , Iskandar Puteri , Johor Bahru District , Johor , Malaysia , and is part of the APM Terminals Global Terminal Network, which holds a minority share in the joint venture. On 13 March 2000, the harbor held its inauguration ceremony, which was officiated by Prime Minister Mahathir Mohamad . The port is situated on the eastern mouth of the Pulai River in south-western Gelang Patah , Johor , Malaysia , in close proximity to

451-467: Is a sturdy cylindrical structure around a special propeller having minimum clearance between the propeller blades and the inner wall of the Kort nozzle. The thrust-to-power ratio is enhanced because the water approaches the propeller in a linear configuration and exits the nozzle the same way. The Kort nozzle is named after its inventor, but many brands exist. The cycloidal propeller is a circular plate mounted on

492-448: Is often higher, due to the need for the tugs' wheelhouse to avoid contact with the hull of a ship, which may have a pronounced rake at the bow and stern. In some ports there is a requirement for certain numbers and sizes of tugboats for port operations with gas tankers . Also, in many ports, tankers are required to have tug escorts when transiting in harbors to render assistance in the event of mechanical failure. The port generally mandates

533-615: Is the carousel tug , winner of the Maritime Innovation Award at the Dutch Maritime Innovation Awards Gala in 2006. It adds a pair of interlocking rings to the body of the tug, the inner on the boat, the outer on the ship by winch or towing hook. Since the towing point rotates freely, the tug is very difficult to capsize. Vintage tugboat races have been held annually in Olympia, Washington , since 1974 during

574-527: The Straits of Johor , which separates the countries of Malaysia and Singapore and the Strait of Malacca . Transshipment accounts for over 90 percent of the port's traffic and was constructed in an attempt to compete with Singaporean ports . In June 2020, 110 containers of toxic electric arc furnace dust, amounting to some 1,864 tonnes, were found at the port. The Malaysian government said it would work to repatriate

615-511: The Z-drive or ( azimuth thruster ) was developed. Although sometimes referred to as the Aquamaster or Schottel system, many brands exist: Steerprop , Wärtsilä , Berg Propulsion , etc. These propulsion systems are used on tugboats designed for tasks such as ship docking and marine construction. Conventional propeller/rudder configurations are more efficient for port-to-port towing. The Kort nozzle

656-546: The 2000s–2010s, used for towing container ships or similar, had around 60 to 65 short tons-force (530–580 kN) of bollard pull, which is described as 15 short tons-force (130 kN) above "normal" tugboats. Tugboats are highly manoeuvrable, and various propulsion systems have been developed to increase manoeuvrability and increase safety. The earliest tugs were fitted with paddle wheels , but these were soon replaced by propeller-driven tugs. Kort nozzles (see below) have been added to increase thrust-to-power ratio. This

697-691: The Egyptian government, and over four months after her grounding;. She became a tourist attraction during that time. After unloading about three quarters of the load in Rotterdam, Ever Given departed on 2 August, mooring in Felixstowe Trinity Container Terminal on 3 August to complete unloading, before going out of service prior to inspection at Harwich Anchorage by Leask Marine ( Orkney ) on behalf of American Bureau of Shipping . She departed 6 August, for refueling at Malta Bunkering Area 3 , preceded by Scot Munchen, on 15 August. During

738-702: The New York State Canal System. Tugboat Annie was the subject of a series of Saturday Evening Post magazine stories featuring the female captain of the tugboat Narcissus in Puget Sound , later featured in the films Tugboat Annie (1933), Tugboat Annie Sails Again (1940) and Captain Tugboat Annie (1945). The Canadian television series The Adventures of Tugboat Annie was filmed in 1957. To date, there have been four children's shows revolving around anthropomorphic tugboats. "Tugger"

779-871: The Olympia Harbor Days Maritime Festival Tugboat races are held annually on Elliott Bay in Seattle , on the Hudson River at the New York Tugboat Race , the Detroit River , and the Great Tugboat Race and Parade on the St. Mary's River . Since 1980, an annual tugboat ballet has been held in Hamburg harbour on the occasion of the festival commemorating the anniversary of the establishment of

820-401: The ability to steer amid high winds and a dust storm. In a separate statement, Evergreen Marine said that it had been told the ship "was suspected of being hit by a sudden strong wind, causing the hull to deviate from [the] waterway and accidentally hit the bottom". The ship ended up with her bow wedged in one bank of the canal and stern nearly touching the other. The ship, which had no tugboat,

861-512: The barge, often with large pushing knees. The first tugboat, Charlotte Dundas , was built by William Symington in 1801. It had a steam engine and paddle wheels and was used on rivers in Scotland. Paddle tugs proliferated thereafter and were a common sight for a century. In the 1870s schooner hulls were converted to screw tugs. Compound steam engines and scotch boilers provided 300 Indicated Horse Power. Steam tugs were put to use in every harbour of

902-482: The canal, planned for later that day. After the canal had been checked for damage, the SCA informed shipping agencies that shipping was to resume from 19:00 local time (17:00 UTC). On 13 April, the SCA announced that the ship had been seized on court orders until the owners paid $ 900 million in damages. On 4 July 2021 the German newspaper Der Spiegel reported that the owners and the SCA had agreed on compensation, although

943-425: The collective pitch control and cyclic in a helicopter. Tugboat fenders are made of high-abrasion-resistance rubber with good resilience properties. They are very popular with small port craft owners and tug owners. These fenders are generally made from cut pieces of vehicle tires strung together. Often the fendering on the sides of the tug is composed of large heavy equipment or aircraft tires attached to or hung on

984-482: The compensation package. Ever Given sailed to Port Said . Hull inspections were carried out, with the vessel finally departing on 12 July, after a seizure delay of more than 100 days. The ship finally arrived at her destination, the Rotterdam Maasvlakte , NL , container terminal on 29 July, after sailing for 17 days, (although the trip was originally expected to take 9 days ), 22 days after her release by

1025-513: The exact amount remained unclear. The settlement had been lowered to $ 540 million by the Suez Canal Authority . The ship departed from the Suez Canal on 7 July for scheduled deliveries of cargo at several European ports. On 7 July 2021, Egyptian authorities released the ship after an unspecified settlement was reached. It was announced that Egypt would also receive a 75-ton tugboat from the ship's Japanese owner, Shoei Kisen Kaisha, as part of

1066-459: The investigation." Aided by high spring tide , the ship was partially freed from sediment and re-floated on 29 March 2021 at 05:42 EGY (03:42 UTC), apart from the bow, which was still caught. The ship was finally freed in the afternoon at 15:05 EGY (13:05 UTC), and the ship started moving under tow towards the Great Bitter Lake for technical inspection, the first step towards reopening

1107-533: The morning of 20 August, Ever Given transited through the Suez Canal, within a 22-vessel convoy. On 20 September 2021 the ship arrived at Qingdao Port anchorage, before berthing alongside the sufficiently large dry dock facilities for repairs on 4 October. Qingdao is also close to Chinese shipping ports where the vessel was projected to re-enter service in late October to mid-November. Photographs taken upon arrival at Qingdao Beihai Shipbuilding Heavy Industry pier indicated bow crumple damage extending as far back as

1148-407: The port terminal and 1,500 acres for the free trade zone. The port has a harbour with a draft of 15 – 19 metres, and a turning basin of 720 metres. The 2007 master plan of the port envisages over 95 berths with 150 million TEU terminal handling capacity. The berths are expected to extend from the mouth of the Pulai River to Malaysia–Singapore Second Link . Tugboat A tugboat or tug

1189-401: The port today is over 12.5 million TEU per year with 174 rubber tyred gantry cranes and 498 prime movers operates around the container facility. In addition to road connectivity, the port is also connected to the peninsula's freight railway system that extends from Johor to the south to southern Thailand to the north, via a 4-track rail terminal. The port development area covers 2,000 acres for

1312-450: The scantling draught, which is used as the basis of hull strength and structural design, is 16.0 metres (52.5 ft). Ever Given has a gross tonnage of 220,940; net tonnage of 99,155; and deadweight tonnage of 199,629 tons at design draught. The ship's container capacity is 20,124  TEU . As with most large container ships, Ever Given ' s propulsion system consists of a single low-speed two-stroke diesel engine coupled to

1353-501: The side of the tug. Some fendering is compression moulded in high-pressure thermic-fluid-heated moulds and have excellent seawater resistance, but are not widely used owing to the cost. Tugboat bow fenders are also called beards or bow puds. In the past they were made of rope for padding to protect the bow, but rope rendering is almost never seen in recent times. Other types of tugboat fender include Tug cylindrical fender, W fender, M fender, D fender, and others. A recent Dutch innovation

1394-400: The underside of the hull, rotating around a vertical axis with a circular array of vertical blades (in the shape of hydrofoils ) that protrude out of the bottom of the ship. Each blade can rotate itself around a vertical axis. The internal mechanism changes the angle of attack of the blades in sync with the rotation of the plate, so that each blade can provide thrust in any direction, similar to

1435-478: The vessel has two 2,500 kW (3,400 hp) bow thrusters . On 9 February 2019, the ship collided with and heavily damaged Finkenwerder , a 25-metre-long (82 ft) HADAG ferry boat which was berthed at Blankenese , near the harbour of Hamburg . Two minutes after the collision, a traffic ban on the Elbe river was mandated due to high winds. At 07:40 Eastern European Time ( UTC+02:00 ) on 23 March 2021, as it

1476-463: The waste. The current port offers 14 berths totaling 5 km of linear wharf length, and a 1.2 million square meters container yard which contains around 240,000 TEU in storage space, 48,374 ground slot and 5,080 reefer points. The berths are serviced by 66 Super Post-Panamax quay cranes, 24 (EEE crane) with 24 rows outreach, 11 of which have a 22 rows outreach and dual hoist 40’ pick, 30 with 22 rows outreach and twin 20’ lift. The total capacity of

1517-470: The world towing and ship berthing. Tugboat diesel engines typically produce 500 to 2,500 kW ( ~ 680 to 3,400 hp ), but larger boats (used in deep waters) can have power ratings up to 20,000 kW (~ 27,200 hp) . Tugboats usually have an extreme power : tonnage -ratio; normal cargo and passenger ships have a P:T-ratio (in kW: GRT ) of 0.35 to 1.20, whereas large tugs typically are 2.20 to 4.50 and small harbour-tugs 4.0 to 9.5. The engines are often

1558-474: Was followed by the nozzle-rudder, which omitted the need for a conventional rudder . The cycloidal propeller (see below) was developed prior to World War II and was occasionally used in tugs because of its maneuverability. After World War II it was also linked to safety due to the development of the Voith Water Tractor, a tugboat configuration that could not be pulled over by its tow. In the late 1950s,

1599-526: Was later cut down to $ 600 million. In early July 2021, the ship was released by the Egyptian authorities following an agreement on compensation. Ever Given ( IMO 9811000 ) is one of 13 container ships built to the Imabari 20000 design developed by Imabari Shipbuilding, 11 of which have been chartered by Evergreen Marine with names starting with " Ever G ". The ship was laid down on 25 December 2015, launched on 9 May 2018 and completed on 25 September 2018. It

1640-404: Was passing through the Suez Canal on its way to Rotterdam from Tanjung Pelepas , Ever Given became stuck (coordinates 30°01′03″N 32°34′49″E  /  30.01761°N 32.58018°E  / 30.01761; 32.58018 ) near the village of Manshiyet Rugola and blocked the canal. According to a statement by the Suez Canal Authority (SCA), the ship ran aground diagonally after losing

1681-471: Was the fifth in a northbound convoy, behind two prior container ships that were each paired with a tugboat. There were fifteen vessels behind it when it ran aground. Traffic in both directions was blocked for just over six days, leading to a traffic jam of over two hundred vessels. On 24 March, Bernhard Schulte Shipmanagement, the technical manager of the ship, denied earlier reports that it had been partially refloated. In addition, trade experts were worried about
