The attacks, targeting a route that allows East-West trade, especially of oil, to use the Suez Canal to save the time and expense of circumnavigating Africa, have pushed some shipping companies to reroute vessels.

Maritime authorities and shipping ministries, including those of Norway and Greece, also warned against sailing in the area.

Below are companies (in alphabetical order) that have decided to pause shipping via the Red Sea:

C.H. ROBINSON

The global logistics group said on Dec. 22 it had rerouted more than 25 vessels around the Cape of Good Hope over the past week, and that number would likely continue to grow.

"Blank sailings and rate increases are expected to continue across many trades into Q1 of 2024," it added.

CMA CGM

The French shipping group has rerouted several vessels via the Cape of Good Hope, while instructing other ships that were scheduled to pass through the Red Sea to reach safe areas and pause their journey until further notice. The group said on Dec. 21 it would impose surcharges on shipments due to longer routes.

EURONAV

The Belgian oil tanker firm said on Dec. 18 it would avoid the Red Sea area until further notice.

EVERGREEN

The Taiwanese container shipping line said on Dec. 18 its vessels on regional services to Red Sea ports would sail to safe waters nearby and wait for further notification, while ships scheduled to pass through the Red Sea would be rerouted around the Cape of Good Hope. It also temporarily stopped accepting Israeli cargo.

MAERSK

The Danish shipping group paused all shipments through the Red Sea until further notice, following a "near-miss incident" involving its ship. On Dec. 19, Maersk said it would reroute its vessels around the Cape of Good Hope. It will also impose extra charges on container transport on affected routes.

Ocean Network Express (ONE), a joint venture of Japan's Mitsui O.S.K. Lines, Nippon Yusen and Kawasaki Kisen Kaisha, said on Dec. 19 it would reroute vessels away from the Suez Canal and the Red Sea.
