RN06: ICE MANAGEMENT – STATE OF THE ART REPORT //Barents 2020RN06: ICE MANAGEMENT– STATE OF THE ART REPORTExecutive SummaryThis report is the result of the work of GroupRN06 – Ice Management - of Phase 4 of Russian-Norwegian Project Barents 2020, the objectiveof which is to recommend common standardsand guidelines for safe offshore design andoperations in the Barents Sea. RN06 dealt with“Ice Management”. The work of RN06 has beencoordinated with the work of Working GroupRN02 “Design of stationary floating units againstice loads in the Barents”. RN02 suggested changesto ISO 19906:2010(E). The suggestions includedthe following revised definition of Ice Management,which is also adopted by RN06:“ice management is the sum of all activities wherethe objective is to reduce or avoid actions from anykind of ice features.”Note: Ice management includes, but is not limited to:• Detection, tracking and forecasting• Physical management, such as icebreaking and iceberg towing• Threat evaluation and alerting”The Scope of Work for RN06 was to prepare astate-of-the-art report on Ice Management (IM). Thereport summarizes the approach to ice managementin four regions where projects have used IM, namelythe Beaufort Sea, where Kulluk and Canmar drillships operated in seasonal ice cover in the 1980’s, theGrand Banks, offshore Sakhalin and at the NorthPole (ACEX project). The planned IM activitiesfor the Shtokman Field are described following thedescriptions of the mentioned IM activities.The report also summarizes the results from aHAZID workshop held to identify hazards connectedto IM activities.• The recognition of the importance ofIM team does not come across clearlyin studies of earlier IM systems andactivities, nor in ISO 19906:2010(E)• Integration of the IM team into the Organizationover the lifetime of a project is important• The HAZID identified several risks thatare related to human behaviour or error• There is a need for continuous trainingand education of all personnel thatwill be or are involved in IM.Recommendations• The operator’s role and involvement inIM throughout the project developmentand implementation should be highlightedin relevant standards and guidelines• Projects should establish a core team of peoplewho know and understand all aspects of IM andwhom should be involved in all project phases• For seasonal or new operations a period oftime should be allowed for training and teamconsolidation before any critical operationsstart. The training should include use of fieldspecific simulators and in-field exercises.• Due to limited documented IM experienceavailable today, future IM operations shouldbe fully recorded and made publicly availableAcknowledgementsWorking Group RN06 of the Barents 2020 projectgratefully acknowledges the contributions from Shellon the ice management experience from Sakhalin2, the Vityaz Production Complex; from C-COREon the experiences for the Grand banks and fromShtokman Development AG on the plans on IM forthe Shtokman Field.Main findings• ISO 19906:2010(E) is currently theonly document where IM is addressed,and suggestions for improvementsare proposed by RN02• IM (when relevant) should be consideredand planned at all developmentstages: from feasibility studies toimplementation into operations• Role and function of IM should be clearlydefined in the project and operationsReport no 2012-0690 201
