What are ‘heavy-lift’ ships? Simply put, they are huge ships that ship ships (and other gargantuan things).
Heavy lift ships, as their name suggests, are designed to carry anything too large or heavy to be easily transported on a conventional cargo vessel – like port terminal cranes, other ships and massive offshore oil and gas rigs.
Semi-submersible heavy lift ships, also known as “flo/flo’s” (for float-on/float-off) have a submerging deck that lowers down into the water allowing floating cargo to be moved into position for loading.
It is quite an alarming sight, the ship eerily looks like it’s sinking – unnaturally level as the main deck disappears below the waterline.
In 2011, our dear John Skelson (we miss you, John… ) photographed Dockwise’s MV Blue Marlin, the largest semi-submersible heavy lift ship at the time, loading up a transport of tugs bound for Africa. Dockwise operates the world’s largest fleet of semi-submersible vessels including the current largest – Dockwise Vanguard, able to carry 110,000 tons of cargo.
The Bayonne wind turbine is finally spinning again after a broken generator part rendered it motionless in June of last year. The 260-foot turbine has been still ever since, costing Bayonne an estimated $25,000 in energy savings every month.
Originally scheduled to be repaired in November, repairs were delayed several times awaiting replacement parts to turbine’s generator.
The part that broke was supposed to last 20 years, but only lasted three. It has been sent to Europe for testing to determine how it broke.
