Two quite unusual shallow-water IBs: the ARC 104 concept design developed by Aker Arctic fulfilled all the requirements set by AGIP KCO, the operator of the giant Kashagan-offshore oil field.
The great challenge in developing these icebreaking tugs was the less draught than in any of the previous vessels, only 2,5 meter operating draught simultaneously with the high icebreaking capacity. For this reason the vessels will be fitted with three Schottel SPR 2020 type 1.600 kW azimuthing pulling thrusters, totalling 4,8 MW.
Drawing challenge: only 2 pictures found!
