Neptune

Named after the Roman sea deity, the Neptune is a one-of-its-kind jackup vessel, specially designed for offshore wind farm installation in the high seas; able to harness the power of the oceanic winds and tides. Its platform is a giant 196.85ft by 131.2ft with a primary crane that can lift 600 tonnes, making Neptune capable of installing the largest offshore turbines in the world. While working with DEME, a world leader in the energy market, I followed the weeks long mission of loading, transporting and building massive offshore turbines at the Thorntonbank Wind Farm, 18.5 miles off the Belgian Coast in the North Sea. Amazing to see these huge structures assembled section by section as they tower in front of you, and equally impressive to witness the speed and efficiency of crews as they worked in the face of extreme weather and tight timelines.
