Arctic EER Today 今日北极
Pub Date : 2010-09-20 DOI: 10.5957/icetech-2010-106
F. Bercha
Technologies, engineering and analysis, and regulatory provisions relating to arctic Escape Evacuation and Rescue (EER) today and in development are reviewed. Current 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 Transport Canada and ISO standards. To facilitate 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 programme. Concurrently, industry and the private sector have addressed the frontier and arctic EER needs through analyses, development of novel systems, and participation in framing performance based standards. Use of conventional EER systems and technologies was found to have 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.
技术,工程和分析,以及有关北极逃生疏散和救援(EER)今天和正在发展的监管规定进行了审查。目前的国家和国际基于绩效的监管制度需要开发工具来评估和设定基于绩效的目标,如可用性和可靠性要求,反映在当前的加拿大交通部和ISO标准中。为了促进加拿大标准中可靠性目标的设定,一项多方面的研究和开发计划在其监管发展的同时启动。全尺寸载人和模型试验、工程和计算机模拟,以及世界范围内关于人在危及生命条件下的表现的磋商和研究,构成了这一研发方案。与此同时,工业界和私营部门通过分析、开发新系统和参与制定基于绩效的标准,解决了前沿和北极的EER需求。研究发现,传统的EER系统和技术在冰层覆盖的水域的适用性有限,需要开发适合北极近海地区环境、操作和后勤要求的系统和程序。本文总结了北极EER中现有的和新兴的监管、建模和研究以及技术发展,并就一些有前途的方向提出了建议。

Arctic Challenges - A Treatise of Past and Recent Developments 北极的挑战-过去和最近的发展论述
Pub Date : 2010-09-20 DOI: 10.5957/icetech-2010-183

In view of the recent announcements by the USA government permitting further drilling in certain areas offshore Alaska and the steady increase in oil prices, it may be again possible to predict that Arctic oil and gas development and transportation projects are imminent. The challenges associated with design and operation of Arctic exploration and production installations are many and have been exhaustively discussed in the past. This paper will summarize these challenges and show how a significant number of them have been addressed in the past and how new technologies may be implemented to alleviate the remaining challenges. In the late seventies and early eighties extensive Arctic R&D work was carried out. A small sample of this work includes the Arctic Pilot Project, the CANMAR icebreaker research program with full scale testing, the Tarsuit artificial island, the Hans island ice load monitoring programs, and the Canadian Coast Guard development of the Canadian Arctic Shipping Pollution Prevention Regulations (CASPPR). The R&D work carried out in Finland and Russia is also discussed. This paper demonstrates how the available results from these projects may be applied in the development of current and new rules and standards. The issues that are still outstanding are highlighted and proposals for possible resolution thereof are made. A presentation of ongoing work for the development of new DNV design guidelines on ice-structure interaction will be presented. The work will be completed in 2011 or early 2012. The project will be based on the new ISO 19906 standard, and will cover both fixed and floating installations. The paper also describes results from a recently completed real-time ice load monitoring program onboard an icebreaking vessel and shows correlation with proposed formulations.
鉴于美国政府最近宣布允许在阿拉斯加近海的某些地区进行进一步的钻探,以及油价的稳步上涨,我们可以再次预测,北极石油和天然气的开发和运输项目即将到来。与北极勘探和生产设施的设计和操作相关的挑战很多,并且在过去已经进行了详尽的讨论。本文将总结这些挑战,并展示过去如何解决其中的重要问题,以及如何实施新技术来缓解剩余的挑战。在70年代末和80年代初,开展了广泛的北极研发工作。这项工作的一个小样本包括北极试点项目、具有全面测试的CANMAR破冰船研究计划、塔休特人工岛、汉斯岛冰负荷监测计划,以及加拿大海岸警卫队制定的加拿大北极航运污染预防条例(CASPPR)。本文还讨论了在芬兰和俄罗斯开展的研发工作。本文演示了这些项目的可用结果如何应用于当前和新的规则和标准的制定。强调了仍未解决的问题,并提出了可能解决这些问题的建议。将介绍正在进行的关于冰-结构相互作用的新DNV设计指南的开发工作。工程将于2011年或2012年初完成。该项目将以新的ISO 19906标准为基础,并将涵盖固定和浮动装置。本文还描述了最近在破冰船上完成的实时冰载监测程序的结果,并显示了与建议配方的相关性。

Past Experience from Arctic Commercial Expeditions 过去北极商业考察的经验
Pub Date : 2010-09-20 DOI: 10.5957/icetech-2010-153
J. Alme, O. Gudmestad
In the past, Norwegian vessels have entered the Arctic for fishing and for hunting whales and seals. The seal hunters needed to go to the iceedge or into the ice to catch the seals and their activity created much needed income in the past. These seal hunters came mainly from the Aalesund area of Norway (many came from the village of Brandal) and from the Tromsø area in the north. Although seal hunting is controversial to day, there might be important learning to bring to new industries like the offshore oil and gas industry and to the navigators in ice infested northern waters. An activity within the research project “PetroArctic” at NTNU has focused on collecting experience data from the seal hunters, (Alme, 2009). A number of interviews with elders (age from 70 to 80+) have been conducted with focus on the physical environmental conditions, vessel behavior in ice and causes of loss of vessels. Among those interviewed were the legendary captain Paul Stark who sailed on sealers from 1950 to 2000 and who was involved in three vessel losses. Newspaper records from the early decades of the 20th century have been reviewed. Prior to the time of steel hull ships with diesel engines, wooden ships with sails and thereafter with steam engines were used. There were frequent losses caused by ice pressure and vessel implosions. Losses were also due to interaction with “ice foots” (Figure1) of multiyear ridges or due to hits from floating ridges on waves. The paper presents characteristic features of vessels used and ice conditions for the different areas where seal hunting took place. These were the Newfoundland area, Labrador coast, Danish Strait, the Area in vicinity of Jan Mayen, North East Greenland coast, Spitzbergen, Eastern Barents Sea towards Novaya Zemlya and the mouth of the White Sea (Figure 2). The causes for the losses or damages to vessels are reviewed in details. In this respect it should be noted that although the ice cap might be shrinking in the future, there will be ice parts of the year over large areas. The ice might even move faster than in the past and get to new areas that traditionally have been ice free. This also relate to the ice of the polar pack that might move more than in the past. There is therefore a strong encouragement to implement the learning of the Arctic pioneers.
过去,挪威船只进入北极捕鱼、捕鲸和海豹。在过去,海豹猎人需要到冰边或进入冰中去捕捉海豹,他们的活动创造了非常需要的收入。这些海豹猎人主要来自挪威的奥勒松地区(许多人来自布兰德尔村)和北部的特罗姆瑟地区。尽管捕猎海豹至今仍有争议,但它可能会给海上石油和天然气工业等新兴行业以及在冰雪覆盖的北方水域航行的导航员带来重要的经验教训。NTNU“PetroArctic”研究项目中的一项活动侧重于收集海豹捕猎者的经验数据(Alme, 2009)。对老年人(年龄从70岁到80岁以上)进行了一些访谈,重点是物理环境条件,船舶在冰上的行为和船舶损失的原因。在接受采访的人中,有传奇船长保罗·斯塔克(Paul Stark),他从1950年到2000年在海豹船上航行,并参与了三次船只损失。我们回顾了20世纪前几十年的报纸记录。在使用柴油发动机的钢壳船之前,使用带帆的木船,之后使用蒸汽机。由于冰压和容器内爆造成的损失经常发生。损失也可能是由于与多年脊的“冰脚”(图1)相互作用,或由于波浪上的浮脊撞击造成的。本文介绍了海豹捕猎的不同地区所使用的船只的特征和冰况。这些地区是纽芬兰地区、拉布拉多海岸、丹麦海峡、扬马延附近地区、格陵兰东北海岸、斯匹茨卑尔根岛、东巴伦支海到新地岛和白海入海口(图2)。详细审查了船只损失或损害的原因。在这方面,应该注意到,虽然冰帽在未来可能会缩小,但一年中大部分地区将会有部分时间是冰的。冰甚至可能比过去移动得更快,到达传统上没有冰的新地区。这也与极地冰群可能比过去移动得更多有关。因此,我们强烈鼓励实施北极先驱的学习。

Ice Hazard Radar 冰险雷达
Pub Date : 2010-09-20 DOI: 10.5957/icetech-2010-179
Barbara J O’Connell
Ships transiting polar regions would benefit from a marine ice navigation radar that could help them differentiate between dangerous multi-year ice and thick first-year ice. Conventional marine radars are designed for target detection and avoidance. Enhanced marine radars provide a higher definition image of the ice that the vessel is transiting through and may help the user to identify certain ice features, but they cannot distinguish first year ice from old ice. This paper presents one approach for the automated identification of sea ice types by a marine radar using cross-polarization technology.

Converting An Icebreaker From An Oil Lubricated Stern Tube Bearing System To A Seawater Lubricated Stern Tube Bearing Considering Environmental And Operating Costs 考虑环境和运行成本,破冰船尾轴管轴承系统由油润滑改为海水润滑
Pub Date : 2010-09-20 DOI: 10.5957/icetech-2010-184
Ken J. Ogle, C. D. Carter
Operational discharges of oil from the stern tube is a common occurrence for ice breakers as propellers are prone to impact from ice causing shafts to flex and seals are unable to maintain a complete barrier to keep seawater out or lubricating oil in the stern tube. Whereas solar radiation generally speeds the break-down of contaminants, the reduced level of sunlight in the Arctic lengthens the degradation process and increases the likelihood that toxic substances in the stern tube lubricating oil will find their way into the food chain. Hence, deemed “biodegradable” lubricants may not be as biodegradable in the Arctic operating environments. However, there exists a proven, viable option for vessels operating in the Arctic to eliminate stern tube oil pollution. This paper outlines the process for converting the sterntube bearings from oil-lubricated white-metal bearings to Thordon COMPAC seawater lubricated bearings, based on recent works on a twin screw ice breaker at a shipyard in Canada.
由于螺旋桨容易受到冰的冲击,导致轴弯曲,密封无法保持一个完整的屏障,以防止海水进入艉管或润滑油进入艉管,因此从艉管中排放油是破冰船的常见现象。虽然太阳辐射通常会加速污染物的分解,但北极地区阳光照射水平的降低延长了降解过程,并增加了船尾管润滑油中有毒物质进入食物链的可能性。因此,被认为是“可生物降解”的润滑剂在北极作业环境中可能不具有可生物降解性。然而,对于在北极作业的船只来说,有一个经过验证的、可行的选择来消除尾管油污染。本文以加拿大某造船厂双螺杆破冰船的最新工程为基础,概述了将尾管轴承由油润滑白金属轴承转换为Thordon COMPAC海水润滑轴承的过程。

This paper outlines the process for converting the sterntube bearings from oil-lubricated white-metal bearings to Thordon COMPAC seawater lubricated bearings, based on recent works on a twin screw ice breaker at a shipyard in Canada.","PeriodicalId":319328,"journal":{"name":"Day 1 Mon, September 20, 2010","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124456068","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}
