Mighty Ships - Season 7 (2013)

The Avataq is a lifeline to Canada's near-Arctic communities, carrying everything from food and furniture to mining equipment and explosives to Quebec's inaccessible northern regions.

Ibn Battuta is capable of breaking up the hardest subsea soil as it deepens the Son Duong Port in Vietnam's poorest province.

Over three months, cable layer Stemat Spirit will connect a wind farm in the Irish Sea to people's homes and businesses in Northwest England, but the job is proving to be a treacherous one. The Irish Sea may be a perfect place to operate a wind farm, but it's a brutal place to actually build one, and completing this mission will mean battling high seas, ferocious winds, and potentially damaged equipment. Join the multi-million-dollar operation as this "rule-breaking" Mighty Ship works both on land and sea, doing the job no other ship can.

Over seven seasons, Mighty Ships has featured 42 of the biggest, most technologically advanced on the planet. This special edition will feature the best of the best: from the world's largest cruise ships to the most powerful warships, from the strongest working ships to smaller, super-specialized vessels.
