Halterm will install three Konecranes - over five RTGs that will span six containers and allow boxes to be stacked five high.
The terminal said the RTGs that will be delivered next February and October, as well as other improvements, will expand existing yard capacity by 40 per cent, to 160,000 TEU, reported IHS Media.
To free up container yard space, three 1970s-era ship-to-shore cranes will be removed, and the terminal will also raise its refrigerated-container capacity by 25 per cent to 600 reefer plugs.
"Our five active, ship-to-shore cranes, with outreach up to 22 containers wide are in excellent working condition and still under-utilised with current berth commitments," Halterm CEO Kim Holtermand was quoted as saying.
During the first nine months of this year, container volume at Halifax increased by 18.3 per cent year on year to 419,426 TEU. Import volumes surged 21 per cent to 208,703 TEU, while exports rose by 15.7 per cent to 210,633 TEU.
Halterm handles ships operated by the Ocean Alliance, Zim Integrated Shipping Services, Maersk Line, Tropical Shipping, Eimskip, Melfi, and TMSI, plus a weekly Oceanex domestic service to Newfoundland.
In June, Halterm handled the 10,062-TEU Zim Antwerp, the largest ship to call at Halifax to date.
