It's been a bit of a Havila feature so far this year, but I could not resist the Havila Clever which was once known as the Kronbas, and together with the Havila Sea which was once the Torbas were the field support vessels in the Brent Field. Most famously during the Greenpeace occupation of the Brent Spar the Kronbas trained its fire monitors on them. Back in the 1970s this vessel was state of the art, but now in the great oilfield in the sky I think.
