In 1999 and 2003, Halifax was visited by two large semi-submersible crane platforms in support of the Sable Offshore project, Saipem 7000 and Heerema's Hermod respectively. The former is the younger of the two (completed in 1987), has the heavier lift cranes (two 7,100 tonne models), and is still in service. Hermod, completed in 1979, has recently been sent for scrap.
Hermod, with her two cranes of 5,000 and 4,000 short ton capacities, was in port around April 12, 2003. She transported and installed the jacket(s) (support legs) for the Alma platform, in 67 metres of water depth. At the time, the daily rate to hire Hermod was reported to be in excess of $150,000 per day.

Hermod is the younger sister of Balder (completed 1978), which is still in service with Heerema.

To replace Hermod, Heerema is building the world's largest semi-submersible crane platform, the Sleipnir, with two 10,000 tonne cranes for a total capacity of 20,000 tonnes.
As an aside, these four images were scanned from film negatives, and they aren't cleaned up as well as they could be. In addition, there was a spot of dust in the scanner that caused an overexposed line to appear in the center of each photo - best visible in the first image.
