SECTION 1 INTRODUCTION

1.1 ScopeThe standard focuses on the performance-areas of the ship's officer on board a tanker who is responsible

for cargo-loading, storage, transport and discharge.

The standard addresses all operational areas related to bulk cargo-handling on board tankers and focuses on

process-related competencies.

The Cargo Operator needs to be able to make correct decisions in the planning and executing phase, detect

and rectify issues caused by malfunctioning equipment and also spot and correct errors made by members

of the crew on operational issues.

1.2 Target groupsThis DNV GL standard is aimed at officers that at times are responsible for liquid bulk cargo operations on

board a product tanker.

1.3 Professional profileThe Cargo Operator should be capable of:

— preparing the vessel for loading and discharging liquid bulk cargo

— safely loading liquid bulk in suitable tanks

— ensuring the cargo is treated in a proper manner during transit

— analysing risks and determining segregation requirements

— communicating with shore-based terminal regarding loading and discharge operations

— efficiently discharging and stripping cargo

— avoiding environmental pollution

— logging required data

— safely discharging slops and vapours

— flushing lines.

1.4 Required performance standardThe performance standard describes how well the officers should perform their duties and tasks.

Whilst undertaking the duties described under [1.3] the officer will comply with all international, national

and local regulations and requirements and the vessel shall be operated safely without damage to life,

environment or property.

SECTION 2 TAXONOMY

2.1 GeneralTaxonomy 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 cognitionEach competence requirement can be classed by the level of cognition required to meet the competence

requirement.

2.3 Professional behaviour verbsThe lists of verbs in the table below are not exhaustive and should be used as guidance only.

Level 1: knowledge (K) To remember or to reproduce on basis of appropriate, previously learned information.

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.

Level 3: application (A) 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.

SECTION 3 COMPETENCE REQUIREMENTS

3.1 GeneralEach competence requirement is derived from a task that needs to be performed. The competence

requirement is stated in objective format to clearly define what has to be done to satisfy the requirements

of the competence. At the same time it facilitates the derivation of assessment criteria and the assessments

to measure individual competencies.

The 705 competence requirements are grouped into 12 distinct functional domains, which are further sub-

divided into 78 subject-based groups. Each competence requirement is allocated a level of cognition that

can be used to determine the type of assessment required to measure competence.

Table 3-1 Competence requirements
