The 157 metre long vessel has been upgraded and refurbished twice in the past 10 years to work in the US Arctic.
Shell’s $193 million upgrade has included new drilling equipment, ice-strengthened sponsons on the hull, emission control technology and, like Kulluk, two blowout preventer stacks with dual shear rams.
The midship turret mooring system has eight anchor lines, along with manoeuvring thrusters.
