Chapter 2 - Structures

Parent topic: Part A - Construction Provisions

2.1 General

  2.1.1 All ships should have structural arrangements adequate to resist the global and local ice loads characteristic of their Polar Classfootnote.

  2.1.2 Each area of the hull and all appendages should be strengthened to resist design structure/ice interaction scenarios applicable to each case.

  2.1.3 Structural arrangements should aim to limit damage resulting from accidental overloads to local areas.

  2.1.4 Polar Class ships may experience in-service structural degradation at an accelerated rate. Structural surveys should, therefore, cover areas identified as being at high risk of accelerated degradation, and areas where physical evidence such as coating breakdown indicates a potential for high wastage rates.

2.2 Materials

  2.2.1 Materials used in ice-strengthened and other areas of the hull should be suitable for operation in the environment that prevails at their location.

  2.2.2 Materials used in ice-strengthened areas should have adequate ductility to match the selected structural design approach.

  2.2.3 Abrasion and corrosion resistant coatings and claddings used in ice-strengthened areas should be matched to the anticipated loads and structural response.
