12、o see that there is alignment between the code text and the preamble.)1 The international Code of Safety for Ships Operating in Polar Waters has been developed to supplement and amend existing IMO instruments in order to increase the safety of ships operation and mitigate its impact on the environme

13、nt in the harsh,remote complex and vulnerable polar waters.(Note 2:As the Polar code not only addresses safety it is proposed to delete the words of safety.)2 The Code acknowledges that the polar environments water operation may impose additional demands on ships,their systems and operation beyond t

14、he existing requirements of the International Convention for the Safety of Life at Sea(SOLAS),1974,the International Convention for the Prevention of Pollution from Ships,1973,as modified by the 1978 Protocol relating thereto(MARPOL 73/78),as amended,and other relevant binding IMO instruments.Such a

15、dditional demands are result from related to the environmental conditions,the remoteness of the operation and other unique factors that are of particular significance in polar waters.(Note 3:It is commented that the preamble should recognize that other adjacent areas could also pose similar risks.)3

16、 The Code also acknowledges that some polar marine ecosystems are particularly vulnerable to ships operation.The Code furthermore acknowledges that the potential rapid rate of change in addition to the severe multiple hazards in polar waters that may,when acting together,present a synergistic risk l

17、evel that is greater than the sum of the specific individual risks normally considered when evaluating risk mitigation measures.This enhanced or multiple effects have been taken into consideration in the development of the Code.(Note 4:it has been proposed that when addressing this potential synergi

18、stic risk level,the precautionary principle should be applied.)Alternative:3 The Code also acknowledges that polar ecosystems are vulnerable to human activities,including ship operation.4 While Arctic and Antarctic waters have a number of some similarities,there are also significant differences.Henc

19、e,although the Code is intended to apply as a whole to both Arctic and Antarctic,the legal and geographical differences between the two areas have been taken into account.(Note 5:To be revisited when the content is agreed to see if there are different requirements for the two areas in the Code.)5 Th

20、e key principles for developing the Polar Code has been to use a risk-based approach in determining scope and to adopt a holistic approach in mitigating identified risks to acceptable levels to minimize the consequences of identified risks.6(Note 6:Delete but as a compromise paragraph 1 has been ame

21、nded.)Alternatively:7 The Code addresses the safety of persons on board,ship and cargo and the prevention of pollution by ships and also considers systems external to the ship such as communication capabilities,availability of information to the navigation systems,traffic monitoring systems as well

22、as search and rescue and pollution response capabilities.(Note 7:This is the preferred alternative however 7 is also proposed deleted.)DE 56/WP.4 Annex 1,page 4 8 Nothing in this Code shall be taken as conflicting with the United Nations Convention on the Law of the Sea,1982,the Antarctic Treaty Sys

23、tem and other international instruments applicable to polar waters.(Note 8:According to MSC.1/Circ.1394,references to relationship to other relevant codes/standards should be in the preamble.)Introduction Goal The goal of this Code is to provide for safe ship operation and the protection of the Pola

24、r environment prevention of pollution from ships by addressing significant risks specific for the present in Polar waters and not explicitly considered by other instruments of the Organization.Sources of hazards inherent in Polar waters The additional sources of hazards inherent in Polar waters cons

25、idered by the Code are The sources of additional or more severe hazards in Polar waters considered by this Code are:.1 physical environmental conditions;.2 high latitude as it affects navigation and ice imagery and communication;.3 environmental sensitivity;and .4 remoteness New proposal:The magnitu

26、de of above listed specific hazards within Polar Waters may differ with respect to geographical location within Polar Waters,time of the year with respect to daylight and ice-coverage etc.Thus the mitigating measures required to address the above specific hazards may vary within Polar Waters.(Note 9

27、:It is questioned if there is a need to state the hierarchy with regard to resolution A.1024(26)and MSC/Circ 1056.Will these still exist after the Polar Code is in force or will they co-exist?)Structure of the Code This Code consists of 2 parts:Part A:Mandatory requirements Part B:Additional guidanc

28、e Part A of this Code has been developed to supplement and amend the requirements of SOLAS,MARPOL and other relevant IMO conventions for ships to which those Conventions apply,taking account of the additional hazards in polar waters.Part B of this Code has been developed to provide additional guidan

29、ce in applying the requirements of Part A.DE 56/WP.4 Annex 1,page 5 General Regulation 1 Definitions(Note 10:We have a list of comments and proposals on definitions,however it is decided to revisited all the definitions once the draft text is agreed,hence only a few have been included.)For the purpo
