Attack No. 2 Sabotage Commercial Vessels in the Strait of Hormuz-An Open Source Study




Situation-Sabotage Attack on Commercial Vessels in the Strait of Hormuz


Background & Analysis

In early May 2019, United Arab Emirates (UAE) reported four commercial vessels were sabotaged near its territorial waters in the Gulf of Oman and the Strait of Hormuz. On June 13 a second attack occurred in the region.  Two ships were targeted this time and both ships sustained severe damage to the hulls from explosions and fires.  One of the ships loaded with Naphtha burned for hours.  The other ship sustained a fire in the engine room.  Reports indicate that Limpet mines, torpedoes or some type of projectiles were fired at the vessels.  The U.S. Navy has video footage of a navel crew suspected to be Iranian, removing unexploded ordinance from the side of one of the vessels. The tankers are being towed to territorial waters of the United Arab Emirates for investigation and salvage operations.  The attacks happened during meetings with Japans Prime Minister Shinzo Abe and Iran’s supreme leader, Ayatollah Khamenei.  Abe was attempting to broker diplomatic talks between the United States and Iran.  Iranian leaders will only enter negotiations on their terms.  Iran sees the Strait of Hormuz and transportation of global energy and security as a key leverage point with Washington and Riyadh. (Guardian, 2019) Iran denies any involvement in the tanker sabotage.  U.S. Secretary of State Mike Pompeo said the U.S. assessment of Iran’s involvement was based in part on intelligence as well as the expertise needed for the operation. (Washington Post, 2019)  Tensions will continue to escalate in the region between Iran, the U.S. & regional players with stake in the energy sector. The U.S. Navy is now considering commercial vessel security escorts in the Strait of Hormuz.  Two commercial shipping lines have already suspended future shipping operations in the region because the heightened risk involved.

What is The Strait of Hormuz?    

  • The Strait of Hormuz is a waterway that separates Iran and Oman, linking the Gulf of Oman with the Persian Gulf and the Arabian Sea

 Why are these Sabotage Attacks Happening?

  • The U.S. has imposed tighter sanctions on Iran’s crude exports (Financial Times, 2019)
  • Since withdrawing from a 2015 international nuclear deal between Tehran and world powers, the Trump Administration has put pressure on Iran with oil sanctions, eliminating waivers that allowed some countries to buy Iranian oil in an attempt to cut crude exports to zero (Reuters, 2019)

Mike Gilday, the director of the Joint Staff; Iran has repeatedly threatened to close the strait in case of a military confrontation with the U.S. “Iranian leaders have publicly threatened to close the Strait of Hormuz; they have backed up those threats with actions, posturing their forces in an effort to intimidate the movement of international trade and energy sources.” (Maritime Executive, 2019)
  • U.S. Secretary of State Mike Pompeo calls the initial attacks in early May “a clear threat to international peace and security, a blatant assault on the freedom of navigation and an unacceptable campaign of escalating tension by Iran.” (Washington Post, 2019)


Why Does the Strait of Hormuz Matter?

  • The Strait of Hormuz, is a vital global oil and gas shipping route (Reuters, 2019)
  • The Majority of crude oil exported from Saudi Arabia, Iran, the UAE, Kuwait and Iraq is shipped through this waterway (Haaretz, 2019)
  • Qatar is the world’s biggest producer and exporter of liquefied natural gas-nearly all of Qatar’s liquefied natural gas is shipped via the Strait of Hormuz (Haaretz, 2019)
  • 100 million barrels of oil per day or one fifth of global oil consumption moves through the Strait of Hormuz (Haaretz, 2019)


Are There Alternative Routes to Transport Oil in Region?

  • The UAE and Saudi Arabia have sought to find other routes to bypass the Strait; including building more oil pipelines (Haaretz, 2019)
