Watch Mighty Ships Season 6 in Australia

She's brand-new and about to make history. The Dutch company Van Oord has just received its new fallpipe vessel called Stornes. She deploys a long hollow pipe that runs from the ship to the seafloor. Rocks are loaded into the pipe and "fall" down to the bottom, hence the term "fallpipe". The rocks are used to provide foundations and protection for pipelines that are then laid on the ocean floor. Stornes has been designed and built specifically for this purpose. Now, MIGHTY SHIPS follows Stornes on a project that has her working deeper than any other fallpipe vessel in history.

She's the "Swiss Army Knife" of the US Navy. Recovery of downed aircraft, towing of sunken vessels, or clearing of debris to reopen a harbor in the wake of a natural disaster... USNS Grasp has done it all. Her cranes enable deep-sea salvage of all sorts. But what makes her special is her ability to support a team of up to 14 Navy divers on dangerous mixed-gas descents to depths of more than 200 metres. She's one of only four vessels in the entire US fleet capable of doing so.

Consistently voted the world's top cruise ship by Condé Nast, Crystal Serenity is full of luxuries. She features contemporary suites, dining by the likes of Nobu, even penthouse suites with a full-service butler. And her guests keep coming back for more - half the passengers on any given sailing are repeat bookings. This cruise will take MIGHTY SHIPS into ports viewers have never seen before, including: the famous sites of Sydney harbour, the port of Melbourne, beautiful Bali and a large-scale furniture load in Semarang, Indonesia.

With 7.5 tons of steel salvaged from the wreckage of the Twin Towers forming her bow stem, USS New York is tribute to those who perished on September 11, 2001. From the images of the World Trade Center, to the banner listing the fallen, to the Broadway street sign donated by NYC's mayor, this ship is a powerful symbol. But she's more than that.

She's an all-in-one mega fishing trawler and factory. Northern Eagle can catch and package fish at the same time. She creates more profit because she doesn't waste time (and fuel) bringing her catch back to shore to be processed. In fact, once she's out to sea, Northern Eagle doesn't return to port until her hold is full of 1500 tonnes of frozen, packaged product ready for market.

Purpose-built to install the world's most powerful wind turbines. Imagine a ship that can raise herself up 15 metres (5 storeys) out of the water to create a stable construction platform in the middle of the sea. Now add a 600-ton crane ready to reach high into the sky. That's Neptune: brand-new, ready and willing to install the world's heaviest and most powerful wind turbines on Belgium's first offshore wind farm.
