With a specialized crane system and five propellers to counter heavy seas, North Sea Giant can perform powerful and precise lifts in seas as high as 4.5 metres – four times the capability of other such vessels. On this voyage, she’s out to lift and install the final massive module of the world’s first subsea gas compression station nearly 300 metres underwater. But when strong winds and currents threaten the delicate operation, her team of underwater robots must come to the rescue before the module crashes the entire project!

Almost three football fields long, the USNS Comfort is second in size only to U.S. Navy aircraft carriers. She is the largest hospital ship on the planet, with up to 1,200 crew, 12 operating rooms, 1,000 beds, and an impressive array of medical equipment. MIGHTY SHIPS joins the USNS Comfort midway through “Operation Continuing Promise” – a six-month mission to provide humanitarian aid to 11 countries in the Caribbean and Latin America. Sailing to the tiny Caribbean island of Dominica, Comfort’s crew sets out to aid 10,000 patients in just nine days.
