The investment in Zim will be made through a rights offering to shareholders. Israel Corp owns 98.4 percent of Zim. The conditions of the rights offering will be determined in the coming days.
The investment will enable Zim to continue with its plan to expand and acquire new ships.
Zim, Israel's largest container shipping firm, has acquired 21 ships to be delivered between 2009 and 2012. It is also upgrading its computer system and its agencies around the world.
Zim's first-quarter results were hurt by rising fuel prices and the decline in the dollar and this was also a factor in postponing the public offering, Israel Corp said.
