A giant of the sea roams the ocean, a huge ship with a massive crane. This is the Oleg Strashnov, one of the biggest monohull crane ships in the world, its mighty boom is able to lift up to 5000 tonnes of weight. It is not only a huge crane, but also an efficient multi tasker, integrated into a ship system that stays stable in the water whatever the weight, whatever the elevation. This is a true marine monster, a legend of the sea.
