5 SECTION 1 INTRODCTION 1.1 Scope Operating lifeboats poses special challenges for the lifeboat coxswain and crew with reference to launching and recovery, boat-handling and survival in a hostile environment, following abandonment. This overview of competencies may help the shipping industry and offshore industry, both from a safety management perspective as well as from a training & assessment perspective. This standard addresses the competencies needed by Lifeboat Coxswains who are responsible for preparing, launching and operating the lifeboat, with the aim to successfully launch the lifeboat, with its full complement of passengers and crew, reach a safe area and await rescue. The emphasis of the standard lies on the emergency evacuation, using a motor propelled survival craft, further to be referred to as lifeboat. Both conventional lifeboats and free-fall lifeboats are covered by the competencies in the standard. The competencies also apply to operating a designated lifeboat for rescue or towing purposes. Since davit-launched life-rafts are often used as a back-up means in case a lifeboat is unavailable the coxswain must also possess a skill-set to prepare and launch this type of craft, with the crew assigned to him. If these rafts are used as a primary means of evacuation (cruise vessels and ferries), the emergency organisation on board will have dedicated people for both the launching stations and the rafts, whose tasks differ from the lifeboat coxswain addressed in this standard. Basic sea-survival competencies as required for all seafarers (e.g. turning a capsized raft, use of lifejackets) are not part of the scope. 1.2 Target groups This DNV GL standard of competence is applicable to those people who are assigned the duties, tasks and responsibilities of Lifeboat Coxswain or Lifeboat Commander, either on board a vessel or offshore installation. 1.3 Professional profile The lifeboat coxswain must able to coordinate and launch the lifeboat, take command and operate it in wind and waves, reach a safe area and coordinate the survival, thereby ensuring safety for all on board. He must be able to use a secondary means to evacuate in case the assigned lifeboat is not available. 1.4 Required performance standard The performance standard describes how well the Lifeboat Coxswain should perform his/her duties and tasks. Whilst undertaking the duties described in [1.3] the Lifeboat Coxswain will, under controlled circumstances, comply with all international, national and local regulations and requirements. nder all circumstances he/ she shall aim to operate the lifeboat safely without damage to life, environment or property.

6 SECTION 2 TXONOMY 2.1 General Taxonomy of the required professional behaviour specifies the level on which the person should be able to operate. It is a hierarchical arrangement, in four (4) levels, of what a person has to master from simple to complex requirements, based on instructional design principles. 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 Levels of cognition Each competence requirement can be classed by the level of cognition required to meet the competence requirement. Level 1: knowledge (K) To remember or to reproduce on basis of appropriate, previously learned information. Level 2: understanding () 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. Level 3: application () To use previously acquired information in new and concrete situations to solve problems that have single or best answers. 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. 2.3 Professional behaviour verbs The lists of verbs in the table below are not exhaustive and should be used as guidance only.

7 SECTION 3 COMPETENCE REQIREMENTS 3.1 General Each competence requirement is derived from a task that needs to be performed at some stage in the operation of a motor-propelled lifeboat. The competence requirement is stated in objective format to clearly define what has to be done to satisfy the requirements of the competence. t the same time it facilitates the derivation of assessment criteria and the assessments to measure individual competencies. The 224 competence requirements are grouped into 7 distinct functional domains that are further subdivided into 32 task groups. Each competence requirement is allocated a level of cognition that can be used to determine the type of assessment required to measure competence. The competence requirements for this operation require theoretical knowledge, intellectual and physical skills.
