Foreword Since its inception, the International Maritime Organization (IMO) has recognized the importance of human resources to

8、the development of the maritime industry and has given the highest priority to assisting developing countries in enhancing their maritime training capabilities through the provision or improvement of maritime training facilities at national and regional levels. IMO has also responded to the needs of

9、 developing countries for postgraduate training for senior personnel in administrations, ports, shipping companies and maritime training institutes by establishing the world Maritime University in Malm, Sweden, in 1983. Following the adoption of the International Convention on Standards of Training,

10、 Certification and Watchkeeping for Seafarers (STCW), 1978, a number of IMO Member Governments suggested that IMO should develop model training courses to assist in the implementation of the Convention and in achieving a more rapid transfer of information and skills regarding new developments in mar

11、itime technology. IMO training advisers and consultants also subsequently determined from their visits to training establishments in developing countries that the provision of model courses could help instructors improve the quality of their existing courses and enhance their implementation of assoc

12、iated Conference and IMO Assembly resolutions. In addition, it was appreciated that a comprehensive set of short model courses in various fields of maritime training would supplement the instruction provided by maritime academies and allow administrators and technical specialists already employed in

13、 maritime administrations, ports and shipping companies to improve their knowledge and skills in certain specialized fields. With the generous assistance of the Government of Norway, IMO developed model courses in response to these generally identified needs and now keeps them updated through a regu

14、lar revision process, taking into account any amendments to the requirements prescribed in IMO instruments and any technological developments in the field. These model courses may be used by any training institution and, when the requisite financing is available, the Organization is prepared to assi

15、st developing countries in implementing any course. E. E. MITROPOULOS Secretary-General V INTRODUCTION Purpose of the model courses The purpose of the IMO model courses is to assist maritime training institutes and their teaching staff in organizing and introducing new training courses or in enhanci

16、ng, updating or supplementing existing training material where the quality and effectiveness of the training courses may thereby be improved. It is not the intention of the model course programme to present instructors with a rigid “teaching package” which they are expected to “follow blindly”. Nor

17、is it the intention to substitute audio-visual or “programmed” material for the instructors presence. As in all training endeavours, the knowledge, skills and dedication of the instructor are the key components in the transfer of knowledge and skills to those being trained through IMO model course m

18、aterial. Because educational systems and the cultural backgrounds of trainees in maritime subjects vary considerably from country to country, the model course material has been designed to identify the basic entry requirements and trainee target group for each course in universally applicable terms,

19、 and to specify clearly the technical content and levels of knowledge and skill necessary to meet the technical intent of IMO conventions and related recommendations. W Use of the model course To use the model course the instructor should review the course plan and detailed syllabus, taking into acc

20、ount the information provided under the entry standards specified in the course framework. The actual level of knowledge and skills and prior technical education of the trainees should be kept in mind during this review, and any areas within the detailed syllabus which may cause difficulties because

21、 of differences between the actual trainee entry level and that assumed by the course designer should be identified. To compensate for such differences, the instructor is expected to delete from the course, or reduce the emphasis on, items dealing with knowledge or skills already attained by the tra

22、inees. He should also identify any academic knowledge, skills or technical training which they may not have acquired. By analysing the detailed syllabus and the academic knowledge required to allow training in the technical area to proceed, the instructor can design an appropriate pre-entry course o

23、r, alternatively, insert the elements of academic knowledge required to support the technical training elements concerned at appropriate points within the technical course. Adjustment of the course objectives, scope and content may also be necessary if in your maritime industry the trainees completi

24、ng the course are to undertake duties which differ from the course objectives specified in the model course. Within the course plan the course designers have indicated their assessment of the time which should be allotted to each learning area. However, it must be 1 SURVEY OF ELECTRICAL INSTALLATION

25、S appreciated that these allocations are arbitrary and assume that the trainees have fully met all the entry requirements of the course. The instructor should therefore review these assessments and may need to reallocate the time required to achieve each specific learning objective. H Lesson plans H

26、aving adjusted the course content to suit the trainee intake and any revision of the course objectives, the instructor should draw up lesson plans based on the detailed syllabus. The detailed syllabus contains specific references to the source material or teaching material proposed to be used in the

27、 course. An example of a lesson plan is shown in the instructor manual on page 41. Where no adjustment has been found necessary in the learning objectives of the detailed syllabus, the lesson plans may simply consist of the detailed syllabus with keywords or other reminders added to assist the instr

28、uctor in making his presentation of the material. H Presentation The presentation of concepts and methodologies must be repeated in various ways until the instructor is satisfied that the trainee has attained each specific learning Objective. The syllabus is laid out in learning objective format and

29、 each objective specifies what the trainee must be able to do as the learning outcome. H Evaluation or assessment of trainee progress Guidance on evaluation or assessment of trainees is given in Part E of the course. The Practical assignments referred to in Section 8 Part D may provide sufficient in

30、formation which will show how effective the transfer of knowledge and understanding has been. For the course to run smoothly and to be effective, considerable attention must be paid to the availability and use of: Implementation properly qualified instructors; support staff; rooms and other spaces;

31、equipment; textbooks, technical papers; and other reference material Thorough preparation is the key to successful implementation of the course. IMO has produced Guidance on the implementation of IMO model courses, which deals with this aspect in greater detail. 2 PART A: COURSE FRAMEWORK Scope The

32、course is concerned with verification of compliance with the requirements in IMO conventions regarding safety of ships, navigation and life at sea. It covers the requirements of the initial, annual, intermediate and periodical surveys, specified in the International Convention for the Safety of Life

33、 at Sea, 1974 (SOLAS 74), as amended, and related documents,)*) together with the necessary procedures for verification of such requirements including: suggested procedures for the carrying out of Convention requirements and further detailed in “Guidance” or “Recommendation” type documents relating

34、to the Convention; suggested acceptance criteria, .e. standards, parameters or guidance towards acceptance of the requirements; any other guidance necessary for the satisfactory determination of these survey requirements, with the aim of issuing the relevant certificates defined in the Convention. T

35、he course does not cover preliminary design or plan approvals, nor does it cover the survey or inspection of chemical tankers, gas carriers, special purpose ships or mobile offshore units. The course should be supplemented by on-the-job training under the supervision of an experienced ship surveyor.

36、 W Objectives The course, supplemented by appropriate on-the-job training, should enable those successfully completing it to: O conduct on behalf of their Administrations the surveys and inspections required by the 1974 SOLAS Convention, as amended, in respect of electrical installations; O report a

37、s necessary on the results of such surveys and inspections to enable the Administration to issue or renew in respect of the ship concerned a Passenger Ship Safety Certificate or a Cargo Ship Safety Construction Certificate and its Supplement, as appropriate, taking into account reports of surveys or

38、 inspections of materials, structure and other equipment in respect of which a certificate is to be issued or renewed, and to issue, renew or endorse the attachment to the above-mentioned certificates; 0 identify, specify and require any repair or replacements in the above regards which may be neces

39、sary to permit issue or renewal of the above certificates; 1) 2) Guidelines on Surveys required by the 1978 SOLAS Protocol, the International Bulk Chemical Code and the International Gas Carrier Code. (Resolution A.560( 14). The interpretation of any convention is a matter to be decided by the Contr

Entry standard Those wishing to enter this course should be fully qualified chief engin

41、eers, or hold an equivalent qualification and have practical experience related to the operation of electrical systems and equipment.* Course certificate, diploma or document On successful completion of the course, a document should be issued certifying that the holder has completed a course of trai

42、ning at the required level of knowledge to conduct survey of electrical installations. Authorization to conduct ship surveys should only be granted following successful completion of appropriate on-the-job training . m Course intake limitations The ratio of trainees to instructors should not exceed

43、20:l in tutorial sessions and 5:l in practical application sessions. Staff requirements All training and instruction should be given by suitably qualified personnel. The senior instructor should be an experienced surveyor having a good knowledge of international requirements related to electrical sy

44、stems as laid down by IMO conventions, Assembly resolutions and MSC/circulars. Those teaching administrative aspects of survey control should also be experienced in these regards. At least one additional instructor with experience as a surveyor should be available for the practical application sessi

45、ons. Teaching facilities and equipment A lecture room or hall, with suitable presentation boards and overhead projector, is sufficient. No special or other equipment is required for classroom work. For the fieldwork, a visit to an appropriate ship(s) under construction or repair should be arranged.

46、For fieldwork, suitable protective clothing and tools and other equipment used for inspection and survey work may be required. * Note: This course may also be used in cross-training experienced ship surveyors of other disciplines. 4 PART A: COURSE FRAMEWORK Teaching aids (A) A I A2 Instructor Manual
