A Traffic Separation Scheme is an area in the sea where navigation of ships is highly regulated. It is meant to create lanes in the water and ships in a specific lane are all going in (roughly) the same direction.

Traffic Separation Scheme maritime traffic-management route-system

A Traffic Separation Scheme or TSS is a traffic-management route-system ruled by the International Maritime Organization or IMO. The traffic-lanes indicate the general direction of the ships in that zone; ships navigating within a TSS all sail in the same direction or they cross the lane in an angle as close to 90 degrees as possible.

Contents

A TSS is created in locations with dense shipping where ships can go in different directions and where there is a high risk of collisions. In the overview below the regulating authority is always the IMO unless stated differently)

International Maritime Organization Specialised agency of the United Nations

The International Maritime Organization (IMO), known as the Inter-Governmental Maritime Consultative Organization (IMCO) until 1982, is a specialised agency of the United Nations responsible for regulating shipping. The IMO was established following agreement at a UN conference held in Geneva in 1948 and the IMO came into existence ten years later, meeting for the first time in 1959. Headquartered in London, United Kingdom, the IMO currently has 174 member states and three associate members.

If below TSS or Routing Scheme is not governed by the IMO the governing body will be mentioned between ' (brackets).

Atlantic Ocean: East

Europe

Vigo City in Galicia, Spain

Vigo is a city and municipality adjoining the Atlantic Ocean in the province of Pontevedra in Galicia, northwest Spain. It is the capital of the comarca of Vigo and Vigo metropolitan area.

Spain Kingdom in Southwest Europe

Spain, officially the Kingdom of Spain, is a country mostly located in Europe. Its continental European territory is situated on the Iberian Peninsula. Its territory also includes two archipelagoes: the Canary Islands off the coast of Africa, and the Balearic Islands in the Mediterranean Sea. The African enclaves of Ceuta, Melilla, and Peñón de Vélez de la Gomera make Spain the only European country to have a physical border with an African country (Morocco). Several small islands in the Alboran Sea are also part of Spanish territory. The country's mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with Gibraltar; to the north and northeast by France, Andorra, and the Bay of Biscay; and to the west and northwest by Portugal and the Atlantic Ocean.

Cabo da Roca cape

Cabo da Roca is a cape which forms the westernmost extent of mainland Portugal, continental Europe and the Eurasian land mass. The cape is in the Portuguese municipality of Sintra, near Azóia, in the southwest of the district of Lisbon, forming the westernmost extent of the Serra de Sintra.

Irish Sea

Tuskar Rock, Ireland island in Ireland

Tuskar Rock is a group of rocks topped by a lighthouse 11 kilometres off the southeast coast of County Wexford, Ireland. It has probably destroyed more ships than any other Irish coastal feature. One hundred and seventy-six wrecks are listed for the Tuskar Rock area at Irish Wrecks Online.

Lighthouse structure designed to emit light to aid navigation

A lighthouse is a tower, building, or other type of structure designed to emit light from a system of lamps and lenses and to serve as a navigational aid for maritime pilots at sea or on inland waterways.

Stena Line Swedish ferry operator

Stena Line is one of the largest ferry operators in the world. It services Denmark, Germany, Ireland, Latvia, the Netherlands, Norway, Poland, Sweden and the United Kingdom, Stena Line is a major unit of Stena AB, itself a part of the Stena Sphere. Stena Line also owns the Swedish vessels of the otherwise German- and Danish-owned Scandlines.

English Channel

The English Channel connects the Atlantic Ocean with the Southern part of the North Sea and belong to the busiest shipping areas in the world with ships going in numerous direction: you have ships that are 'just' passing through from the Southwest to Northeast (or vice versa), ships going to or departing from one of the many ports around the English Channel and then the ferries crossing the channel. In the English Channel several TSS schemes are in operation: [1] [2]

English Channel Arm of the Atlantic Ocean that separates southern England from northern France

The English Channel, also called simply the Channel, is the body of water that separates Southern England from northern France and links the southern part of the North Sea to the Atlantic Ocean. It is the busiest shipping area in the world.

Atlantic Ocean Ocean between Europe, Africa and the Americas

The Atlantic Ocean is the second largest of the world's oceans, with an area of about 106,460,000 square kilometers. It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World".

North Sea marginal sea of the Atlantic Ocean

The North Sea is a marginal sea of the Atlantic Ocean located between the United Kingdom, Denmark, Norway, Sweden, Germany, the Netherlands, Belgium and France. An epeiric sea on the European continental shelf, it connects to the ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than 970 kilometres (600 mi) long and 580 kilometres (360 mi) wide, with an area of 570,000 square kilometres (220,000 sq mi).

Southern North-Sea

The Southern North Sea overlaps the TSS mentioned in the English Channel above [1]

Russia and Norway

TSS in these areas aren't governed by the IMO but by either the government of Russia (marked: R) or the Norwegian government (marked N)

Baltic Sea

Most TSS in the Baltic Sea are governed by the IMO, but some are the responsibility of the local country.

North Sea: Denmark, Germany, The Netherlands

In the area of the North Sea which lies North of the earlier mentioned Dover Straits several TSS are in place to manage the traffic to and from some of the busiest ports in the world such as: Port of Rotterdam, Bremerhaven, Port of Amsterdam, Antwerp etc. All of these TSS and routing-schemes are governed by the IMO

Mediterranean Sea and Black Sea

Numerous TSS and similar routing-schemes are active in the Mediterranean Sea, the Black Sea and the waters within this area such as the Adriatic Sea. On the charts of the United Kingdom Hydrographic Office some 56 schemes can be found. [1] Many of these schemes are governed by the local state, such as Italy, Spain, Croatia etc.)

Some of the most important TSS are mentioned below. A complete list can be retrieved from the Notice 17: TRAFFIC SEPARATION SCHEMES AND INFORMATION CONCERNING ROUTEING SYSTEMS SHOWN ON ADMIRALTY CHARTS [1]

Atlantic Ocean: West

On the Western shores of the Atlantic Ocean you can find the coasts of North America with the United States of America and Canada. Then there is the Caribbean Sea, the Gulf of Mexico and the South American coast.

Caribbean Sea and Gulf of Mexico

East Coast of North America

Indian Ocean

Indian Ocean: Africa

Apart from the TSS schemes in the Mediterranean above it, the African continent has only a few TSS schemes around the waters of South Africa:

Arabian Peninsula

This covers the Red Sea, Arabian Sea and Persian Gulf. Some 15 TSS schemes can be found in this area: in the Red Sea you find the traffic using the Suez Channel while in the Persian Gulf much of the traffic are the (large) oil and gas tankers to Iran and Iraq. All TSS here are governed by the IMO, except the Approaches to Yanbu which is the responsibility of the Kingdom of Saudi Arabia)

Central Indian Ocean

The Indian Ocean region links in the West with the (above) area of the Arabian Sea and the African Continent. And in the East it borders with the Pacific Ocean. Apart from schemes in these border-areas only two TSS are mentioned around India and Sri Lanka:

Malacca Strait, Singapore Strait and Sumatra

On the Eastern borders of the Indian Ocean you find the Malacca Strait, Singapore Strait and the waters around the Indonesian island of Sumatra. This is a very busy shipping area and also very dangerous (see also this section).

Pacific Ocean

China Seas

Some 25 TSS schemes are in operation in and around the China Seas. Shipping is very busy around Hong Kong, the mainland of South-East China and around Taiwan.

Some of the most important TSS schemes in this area:

Japan

In Japan there are 5 TSS Schemes all governed by the Japanese government. Apart from these mandatory schemes there are also Voluntary and Recommended schemes. These are not shown on Admiralty Charts and (thus) not shown in this overview

Korea and Russia (Pacific Coast)

In (North) Korean and Pacific Russian waters some 35 schemes are in operation with only 5 of them being governed by the IMO. All major ports in this area have a TSS in operation. In North Korea none of the TSS schemes are IMO schemes; only locally governed by the North Korean central government. Below an overview of the IMO schemes and some of the most important locally governed schemes:

Philippines, Borneo and Indonesia

There are six TSS around the Philippines and one in Malaysia. None of them are governed by the IMO:

Australia and Papua New Guinea

In this area there are 5 TSS in operation: two in the Bass Strait, governed by the IMO and three leading to Australian ports, governed by Australia.

Aleutian Islands, Alaska, US West Coast, Canada and Mexico

On the East side of the Pacific Ocean the TSSes are divided in two groups: the North side with the West Coast of Mexico and everything North of that. And the other group are formed by the West coast of Central and South America.

The TSS in the far North around the Aleutian Islands and Alaska are not put in place because of the high density of shipping but the nature of the ships and the vulnerability of the area.

The TSS schemes are:

Pacific: Central and South America

The IMO governs 16 TSS schemes on the Pacific side of Central and South America:

Bras dOr Lake Lake in Nova Scotia, Canada

Bras d'Or Lake is an inland sea, or large body of partially fresh/salt water in the centre of Cape Breton Island in the province of Nova Scotia, Canada. Bras d'Or Lake is sometimes referred to as the Bras d'Or Lakes or the Bras d'Or Lakes system; however, its official geographic name is Bras d'Or Lake, as it is a singular entity. Canadian author and yachtsman Silver Donald Cameron describes Bras d'Or Lake as "A basin ringed by indigo hills laced with marble. Islands within a sea inside an island." The lake is connected to the North Atlantic by natural channels; the Great Bras d'Or Channel north of Boularderie Island and the Little Bras d'Or Channel to south of Boularderie Island connect the northeastern arm of the lake to the Cabot Strait. The Bras d'Or is also connected to the Atlantic Ocean via the Strait of Canso by means of a lock canal completed in 1869—the St. Peters Canal, at the southern tip of the lake.

Gulf of Mannar gulf

The Gulf of Mannar is a large shallow bay forming part of the Laccadive Sea in the Indian Ocean. It lies between the west coast of Sri Lanka and the southeastern tip of India, in the Coromandel Coast region. The chain of low islands and reefs known as Ramsethu, also called Adam's Bridge, which includes Mannar Island, separates the Gulf of Mannar from Palk Bay, which lies to the north between Sri Lanka and India. The Malvathu Oya of Sri Lanka and the estuaries of Thamirabarani River and Vaipar River of South India drain into the Gulf. The dugong is found here.

HMS Hydra was a Royal Navy deep ocean hydrographic survey vessel, the third of the original three of the Hecla class. The ship was laid down as yard number 2258 on 14 May 1964 at Yarrow Shipbuilders, at Scotstoun on the River Clyde and launched on 14 July 1965 by Mary Lythall, wife of the then Chief Scientist, Basil W Lythall CB (1919–2001). She was completed and first commissioned on 4 May 1966 and, as the replacement for the survey ship HMS Owen, her commanding officer and many of her ship's company formed the first commission of HMS Hydra. She was decommissioned and sold to the Indonesian Navy in 1986 and renamed KRI Dewa Kembar ; she was still in service in 2006.

Geography of Nova Scotia

Nova Scotia is a province located in Eastern Canada fronting the Atlantic Ocean. One of the Maritime Provinces, Nova Scotia's geography is complex, despite its relatively small size in comparison to other Canadian provinces.

Adolphus Channel strait

The Adolphus Channel or the Albany passage is a channel located in the Torres Strait, situated northeast of the Cape York Peninsula, in Queensland, Australia. The channel runs north of the Albany Island, one of the islands if the Manar group of the Torres Strait Islands archipelago, and to the south of Mount Adolphus Island. Adolphus Channel is a major shipping route for traffic passing from the eastern coast of Australia to the Gulf of Carpentaria, Arafura Sea and regions further west. It is about 7 km across at its narrowest point, mostly less than about 20 m in depth and opens towards the west and towards the east. Submarine dunes up to 5 m tall migrate along the Adolphus Channel seabed, posing a potential risk to safe navigation.

Geography of Franz Josef Land

The Geography of Franz Josef Land refers to an island group belonging to Arkhangelsk Oblast of Russia. It is situated in the Barents Sea of the Arctic, north of Novaya Zemlya and east of Svalbard. At latitudes between 80.0° and 81.9° north, it is the most northerly group of islands associated with Eurasia. The extreme northernmost point is Cape Fligely on Rudolf Island. The archipelago consists of 191 ice-covered islands with a total area of 16,134 km2 (6,229 sq mi). It is currently uninhabited. The archipelago is only 900 to 1,110 km from the North Pole, and the northernmost islands are closer to the Pole than any other land except for Canada's Ellesmere Island and Greenland. The largest island is Zemlya Georga which measures 110 km (68 mi) from end to end. The highest point in the archipelago is on Ostrov Viner-Neyshtadt which reaches 620 m (2,034 ft) above sea level. The central cluster of large islands in the midst of the archipelago forms a compact whole, known as Zichy Land, where islands are separated from each other by very narrow sounds that are frozen most of the year.
