The developing national and international regulatory performance based regime has necessitated the development of tools for the evaluation and setting of performance based goals such as availability and reliability requirements, mirrored in current draft Transport Canada and ISO standards. To facilitate the reliability assessment and consequent setting of reliability targets in the Canadian standards, a multifaceted research and development program was initiated in parallel with its regulatory developments. Full scale manned and model tests, engineering and computer simulation, and world wide consultations and studies on human performance in life threatening conditions, comprise this R&D program. Use of conventional EER systems and technologies has limited applicability in ice populated waters, requiring the development of systems and procedures suited to the environmental, operational, and logistical requirements of arctic offshore regions. The paper summarizes available and emerging regulatory, modeling and research, and technological developments in arctic EER and gives recommendations on a number of promising directions.","PeriodicalId":415232,"journal":{"name":"Day 1 Sun, July 20, 2008","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128637687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Arctic sea ice extent has been reducing at a relatively modest rate of 3-4% per decade (annually averaged) but since 1996 this has speeded up to 10% per decade and in summer 2007 there was a massive collapse of ice extent to a new record minimum of only 4.1 million sq km. Thickness has been falling at a more rapid rate (43% in the 25 years from the early 1970s to late 1990s) with a specially rapid loss of mass from pressure ridges. The summer 2007 event may arise from an interaction between the long-term retreat and more rapid thinning rates. We review thickness monitoring techniques which show the greatest promise on different spatial and temporal scales, and for different purposes. We show results from some very recent work from submarines.","PeriodicalId":415232,"journal":{"name":"Day 1 Sun, July 20, 2008","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116476992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For economic operation, two different fore body and aft body for both ice and open performance evaluations are presented in this paper. The major objective of this study is the suggestion of the optimum ice breaking hull form according to its operation condition. The open and ice performance of the icebreaking vessel was validated at Samsung Ship Model Basin and Aker Arctic Technology Inc., respectively. From the present study, it has been found that the hull form optimized at extreme ice condition gave about 40.0% improved power performance at 1.67M level ice condition and about 10.0% inferior propulsion at open condition compared to the hull form with ice breaking bulbous bow.

In CPP designs, the recently released IACS URI3 – “Machinery Requirements for Polar Class Ships” provides the design forces on the propeller blade resulting from propeller-ice interaction. These design forces are also the source of the spindle torques, which can be used for the determination of CPP mechanism scantlings. In this paper, ice loads formulae in URI3 for open and ducted CPP will be adopted for an existing ice CPP for its mechanism check to evaluate the rationality of the Rule. To further explore the influence from different design principles on CPP scantlings, both the maximum life time ice load and the blade failure load provided in URI3 will be applied on the existing CPP to check its mechanism strength. The detailed comparison of the strength check outcomes provides very useful information for ice CPP design.","PeriodicalId":415232,"journal":{"name":"Day 1 Sun, July 20, 2008","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130393538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(AARC) was inaugurated in March 2006. The new facility is located in Helsinki at the Vuosaari Marine Business Park, next to the new Helsinki harbour. This facility is the third in the history of Aker Arctic starting in 1969 with Wärtsilä Ice Model Basin (WIMB).\u0000 Today the new facility has been in operation for two a half years. This period has been still quite a lot of learning and developing practices even the transfer of the ice making happened quite well.\u0000 The new facility has also opened new possibilities.\u0000 The paper describes the new facilities and highlights the work done so far. Also among other things the further development possibilities of the AARC FGX model ice is discussed.\u0000 Making of thick weak ice in the model basin has always been quite a problem. In this respect the enhanced use of AARC FGX ice has given new possibilities in testing. Firstly ice sheets with thickness close to 100 mm were prepared for the new Russian multipurpose icebreaker project to simulate full-scale level ice thickness of 2.85m. Recently model ice with thickness close to 240 mm with flexural strength of 10-20 kPa was manufactured.\u0000 The paper will discuss also the processes of making these thick/week ice sheets.","PeriodicalId":415232,"journal":{"name":"Day 1 Sun, July 20, 2008","volume":"7 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131839023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
