1.1.3 At the Owner’s request and in order to enhance safety and awareness on board during ship operation, the ShipRight SEA(ICE) Ship Event Analysis Procedure may be applied. This procedure may be applied to all ships where it is intended to provide a hull surveillance system for monitoring of the ship’s hull girder stresses and local ice loads when the ship is navigating in ice, and warning the ship’s personnel that the load levels or the frequency and magnitude of ice impacts are approaching a level where corrective action is advisable. See Pt 1, Ch 2, 2.8 Descriptive notes 2.8.3 and Pt 3, Ch 16, 6 Ship Event Analysis.

1.1.4 At the Owner’s request and in order to enhance safety, the ShipRight FDA ICE Fatigue Induced by Ice Loading Procedure may be applied. This procedure is supplementary to the FDA procedures and is to assess fatigue damage induced by ice loads for ships navigating in ice-covered regions. The objective of the ShipRight FDA ICE procedure is to provide technical guidelines to assess fatigue at the end connections of stiffeners in the ice belt regions under ice loading. See Pt 1, Ch 2, 2.3 Class notations (hull) 2.3.17 and Pt 3, Ch 16, 4 Fatigue design assessment.
