1 STANDARD FOR CERTIFICATION NO COMPETENCE OF SHIP S ELECTRICAL OFFICERS AND ENGINEERS FEBRUARY 2007

2 FOREWORD (DNV) is an autonomous and independent foundation with the objectives of safeguarding life, property and the environment, at sea and onshore. DNV undertakes classification, certification, and other verification and consultancy services relating to quality of ships, offshore units and installations, and onshore industries worldwide, and carries out research in relation to these functions. Standards for Certification Standards for Certification (previously Certification Notes) are publications that contain principles, acceptance criteria and practical information related to the Society's consideration of objects, personnel, organisations, services and operations. Standards for Certification also apply as the basis for the issue of certificates and/or declarations that may not necessarily be related to classification. A list of Standards for Certification is found in the latest edition of Pt.0 Ch.1 of the Rules for Classification of Ships and the Rules for Classification of High Speed, Light Craft and Naval Surface Craft. The list of Standards for Certification is also included in the current Classification Services Publications issued by the Society, which is available on request. All publications may be ordered from the Society s Web site Comments may be sent by to rules@dnv.com Comprehensive information about DNV and the Society's services is found at the Web site Det Norske Veritas Computer Typesetting (FM+SGML) by Det Norske Veritas If any person suffers loss or damage which is proved to have been caused by any negligent act or omission of Det Norske Veritas, then Det Norske Veritas shall pay compensation to such person for his proved direct loss or damage. However, the compensation shall not exceed an amount equal to ten times the fee charged for the service in question, provided that the maximum compensation shall never exceed USD 2 million. In this provision "Det Norske Veritas" shall mean the Foundation Det Norske Veritas as well as all its subsidiaries, directors, officers, employees, agents and any other acting on behalf of Det Norske Veritas.

3 Standard for Certification - No Background DNV SeaSkill has been set up to use the principles of classification to help improve and codify competence at all levels within the maritime industry. It is necessary to independently test and verify the competence of individuals in relation to specific jobs or positions on-board as well as on-shore. DNV SeaSkill offers the industry the necessary tools and expertise to evaluate the competence of individuals based on Standards for Certification of Competence. These standards can be used to provide appropriate training, and to assess and certify individuals as being fit to carry out the functions as described in each standard. Currently, there is no globally accepted competence standard for "Ship's Electrical Officers and Engineers". The STCW Code 95 specifies competence requirements on operational and management level on subjects related to electrical, electronic and control engineering for the officers in the engine department. However, the requirements are not very detailed and there is no standard for independently verifying and certifying the competence of ship's electrical officers and engineers. DNV SeaSkill works in close cooperation with the shipping industry. Our standards are in fact developed by Committees of Experts (CoE) consisting of leading members from the industry. All DNV SeaSkill standards are developed with the active participation of the shipping industry. The DNV Committee of Experts (CoE) in Singapore has representation from owners, operators and industry bodies. This committee has been instrumental in choosing to work on the standard, and the contents of the standard itself. A group of experts in Helsinki consisting of persons from manufactures of electrical equipment, owners and educational institutions has also made crucial contributions to the standard. The standard can be applied in the following ways: As a guide to the competence requirements that employers should place on the ship's electrical officers and engineers they employ. As a guide to those who are already working or wish to work in the position of ship's electrical officers. As a guide to training providers, who can develop courses according to the requirements of the standard. For the assessment and certification of ship's electrical officers and engineers. This would be done by DNV Sea- Skill, and would provide an independent and transparent mechanism for certification.

Taxonomy of the required professional behaviour is a hierarchical arrangement, in four (4) levels, of what a person has to master from simple to complex requirements based on Bloom s taxonomy i.e. Bloom, B. S. et al., (1956) Taxonomy of Educational Objectives The Cognitive Domain. For every next level, it is a prerequisite that the preceding level is mastered. The required professional behaviour is expressed by means of a verb. 2.2 Taxonomy Level 1: Knowledge (K) To remember or to reproduce on basis of appropriate, previously learned information. Suggested professional behaviour verbs on this level 1 are for example: Define, describe, find, identify, label, list, match, mention, name, outline, recognise, record, repeat, reproduce and state Level 2: Understanding (U) To give meaning to new situations and or new material by recollection and using necessary present information. To give evidence of insight in certain activities. Called comprehension by Bloom. Suggested professional behaviour verbs on this level 2 are for example: Classify, cite, comprehend, convert, discuss, distinguish, estimate, explain, extend, generalise, give examples, interpret, make sense out of, paraphrase, predict, restate (in own words), summarise, trace and translate Level 3: Application (A) To use previously acquired information in new and concrete situations to solve problems that have single or best answers. Suggested professional behaviour verbs on this level 3 are for example: Act, administer, apply, articulate, arrange, assess, calculate, chart, collect, compute, construct, contribute, control, demonstrate, determine, develop, discover, establish, extend, implement, include, inform, instruct, manipulate, operate, participate, predict, prepare, preserve, produce, project, provide, report, review, show, solve, teach, transfer, use and utilise Level 4: Integration (I) To separate information into their component parts, to examine such information to develop divergent conclusions by identifying motives or causes, making inferences, and/or finding evidence to support generalizations. To creatively apply prior knowledge and skills to produce a new or original whole. To judge the value of material based on personal values or opinions, resulting in an end product, with a given purpose, without real right or wrong answers. Called analysis, synthesis and evaluation by Bloom. Suggested professional behaviour verbs on this level 4 are for example: Analyse, appraise, categorise, combine, communicate, compare, compile, compose, conclude, contrast, correlate, create, criticise, decide, defend, design, develop, devise, differentiate, discriminate, express, facilitate, formulate, generate, hypothesise, illustrate, incorporate, integrate, interpret, invent, judge, justify, model, modify, negotiate, organise, outline, plan, point out, prioritise, rearrange, recommend, reconstruct, reinforce, relate, reorganise, revise, select, separate, solve, structure, subdivide, substitute, support and validate Professional behaviour verbs The lists of verbs in to are not exhaustive and should be used as guidance only Measurement of Level 3 and 4 competence Application (A) and Integration (I) are normally measured by practical assignments. Practical assignments may be of a theoretical nature, depending on the competences to be measured. They may include the use of multiple choice questions, open ended questions, case studies, etc. when measuring competences such as calculations, planning, reporting etc.
