Iranian oil tankers all switching off AIS systems to avoid tracking movements

Iranian oil tankers all switching off AIS systems to avoid tracking movements Iran’s fleet of 11 VLCC tankers have all switched off AIS systems so they can not be tracked. This was done to hide their oil movements with upcoming sanctions taking effect.

The tankers have 20 million barrels of oil aboard. Any mariner that has seen these tankers moving without AIS should report their positions. This is direct violation of Regulation 19 of SOLAS Chapter V РCarriage requirements for shipborne navigational systems and equipment Рsets out navigational equipment to be carried on board ships, according to ship type. In 2000, IMO adopted a new requirement (as part of a revised new chapter V) for all ships to carry automatic identification systems (AIS) capable of providing information about the ship to other ships and to coastal authorities automatically.

The regulation requires AIS to be fitted aboard all ships of 300 gross tonnage and upwards engaged on international voyages, cargo ships of 500 gross tonnage and upwards not engaged on international voyages and all passenger ships irrespective of size. The requirement became effective for all ships by 31 December 2004.

The Iran tankers include the VLCC ships Diona, Dino, Sea Cliff, Happiness, Navarz, Kharg Island 9 , Kharg island 8 Hedy, Kharg Island 8 Humanity, Sep Soroosh 8 , Snow and Kharg Island 7 all have switched of AIS and gone dark.

If any mariners see’s these VLCC tankers underway without AIS working they should be reported to the USCG and the International Maritime org.
