Intention, scope and applicability

(1) In extension to the regulations provided by “GL Rules for Classification and Construction: III – Offshore Technology – Part 2: Offshore Installations”, this document gives some additional procedures for estimating Sea Ice Properties and Ice Loads on Offshore Structures.

(2) Furthermore, safety related issues are mentioned, which are not yet included in other regulations such as SOLAS or extend beyond those considering the much more hostile environment conditions in arctic areas

(3) The methods provided herein do not claim to deliver reliable results but represent a selection of the most easy to use approximation methods. It is strongly advised to seek technical advice from expert organisations for arctic offshore developments.

(4) Application of any of the methods given herein shall be performed with great caution. Any results should be carefully checked and because of the inadequacy of those methods available to the public, model trials for the specific solutions developed are strongly recommended.

(5) Additionally, advanced numerical simulation methods should be employed. Consultation with expert organisations that can provide applicable simulation tools is strongly recommended.

(6) In no case may any one of the methods provided herein be taken as reliable, valid method for design load calculation. Any determination processes employed and results thereof shall be agreed upon with the Authorities.
