Design philosophy of the Sanaborg
In 2012, Royal Niestern Sander in Delfzijl delivered the ‘Sanaborg’ to Wagenborg Offshore. This Ice Breaking Multipurpose Support Vessels (IMSV) has been jointly developed, by the shipyard, Wagenborg and Conoship, for offshore services in shallow water and under arctic conditions. The ‘Sanaborg’ is more efficient than the existing vessels because of the new hull form, which was developed by Conoship International. Design target was to reach a minimum speed of 4.0 knots in unbroken first year ice of 0.60 m thickness. Model tests were conducted to verify the icebreaking performance in deep and shallow waters, as well as “washing and breaking the ice” to penetrate grounded ridges travelling stern first. Equipped with two Wärtsilä Icepod thrusters, the vessel reaches a bollard pull of 36.3 mT and has excellent ice management capabilities.
The vessel has been converted to a luxury explorer yacht named Ragnar by Icon Yachts and delivered in 2020.
