Crowley Maritime said it awarded an additional contract for improvements and upgrades at its Isla Grande port terminal in San Juan, Puerto Rico.

Puerto Rico’s Del Valle Group won the $21m contract.

It includes expanding the terminal’s capacity for handling refrigerated containers; paving 15 acres to accommodate container stacking; installing a new electrical substation to provide power for three new ship-to-shore gantry cranes; constructing a new seven-lane terminal exit gate; and installing hardware required for a new, state-of-the-art terminal operating software system.
