FOREWORDDET NORSKE VERITAS (DNV) is an autonomous and independent foundation with the objectives of safeguarding life, prop-erty and the environment, at sea and onshore. DNV undertakes classification, certification, and other verification and consultancyservices relating to quality of ships, offshore units and installations, and onshore industries worldwide, and carries out researchin relation to these functions.Standards for CertificationStandards for Certification (previously Certification Notes) are publications that contain principles, acceptance criteria and prac-tical information related to the Society's consideration of objects, personnel, organisations, services and operations. Standardsfor Certification also apply as the basis for the issue of certificates and/or declarations that may not necessarily be related to clas-sification. 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.

Standard for Certification - No. 3.317, April 2009

BackgroundDNV SeaSkill has been set up to use the principles of classifi-cation to help improve and codify competence at all levelswithin the maritime industry.This standard specifies the competence requirements for ship'sofficers who can be made responsible for liquid bulk cargohandling operations on board a crude oil tanker.The standard focuses on the performance-areas of the ship's of-ficer on board a crude oil tanker who is responsible for cargo-loading, storage, transport and discharge.The standard addresses all operational areas related to han-dling liquid bulk on board a crude oil tanker and focuses pri-marily on competencies related to process control.

The responsible officer needs to be able to make correct deci-sions in the planning and executing phase, detect and rectify is-sues caused by malfunctioning equipment and also spot andcorrect errors made by members of the crew on operational is-sues.This standard can be applied in the following ways:— as a guide to the competence requirements that employers

should place on the Cargo Operator, responsible for liquidbulk-cargo operations on board a crude oil tanker

— as a guide to training providers, for developing courses ac-cording to the requirements of the standard

— for the assessment of cargo-operators on board.

1. Introduction1.1 ScopeThe standard focuses on the performance-areas of the ship's of-ficer 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 compe-tencies.The Cargo Operator needs to be able to make correct decisionsin the planning and executing phase, detect and rectify issuescaused by malfunctioning equipment and also spot and correcterrors made by members of the crew on operational issues.

1.2 Target groupsThis DNV Standard for Certification is aimed at officers thatat times are responsible for liquid bulk cargo operations onboard a crude oil tanker.

1.3 Professional profileThe Cargo Operator should be capable of:

— preparing the vessel for loading and discharging liquidbulk 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 load-

ing 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 officersshould perform their duties and tasks.Whilst undertaking the duties described under 1.3 the officerwill comply with all international, national and local regula-tions and requirements and the vessel shall be operated safelywithout damage to life, environment or property.

2. Taxonomy2.1 GeneralTaxonomy of the required professional behaviour specifies thelevel on which the person should be able to operate. It is a hi-erarchical arrangement, in four (4) levels, of what a person hasto master from simple to complex requirements, based on in-structional design principles. For every next level, it is a prerequisite that the preceding levelis mastered. The required professional behaviour is expressedby means of a verb.

2.2 Levels of cognitionEach competence requirement can be classed by the level ofcognition required to meet the competence requirement.

2.3 Professional behaviour verbsThe lists of verbs in the table below are not exhaustive andshould 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 informa-tion. 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 conclu-sions 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.

3. Competence Requirements3.1 GeneralEach competence requirement is derived from a task that needsto be performed. The competence requirement is stated in ob-jective format to clearly define what has to be done to satisfythe requirements of the competence. At the same time it facil-itates the derivation of assessment criteria and the assessments

to measure individual competencies.The 695 competence requirements are grouped into 12 distinctfunctional domains, which are further sub-divided into 74 sub-ject-based groups. Each competence requirement is allocated alevel of cognition that can be used to determine the type of as-sessment required to measure competence.
