General comments

Many candidates are well prepared for this unit assessment and provide comprehensive and relevant answers in response to the demands of the questions. This includes the ability to demonstrate understanding of knowledge by applying it to workplace situations. There are other candidates, however, who appear to be unprepared for the unit assessment and who show both a lack of knowledge of the syllabus content and a lack of understanding of how key concepts should be applied to workplace situations. This report has been prepared to provide feedback on standard date and on-demand IOG1 st th examinations sat between 1 March and 30 April 2014. Feedback is presented in these key areas; examination technique, command words and learning outcomes and is designed to assist candidates and course providers prepare for future assessments in this unit. Candidates and course providers will also benefit from use of the ‘Guide to the NEBOSH International Certificate in Oil and Gas Operational Safety’ which is available via the NEBOSH website. In particular, the guide sets out in detail the syllabus content for IOG1 and tutor reference documents for each Element. Additional guidance on command words is provided in ‘Guidance on command words used in learning outcomes and question papers’ which is also available via the NEBOSH website. Candidates and course providers should also make reference to the IOG1 ‘Example question paper and Examiners’ feedback on expected answers’ which provides example questions and details Examiners’ expectations and typical areas of underperformance.

Unit IOG1 Management of international oil and gas operational safety Candidate performance This report covers all examinations, both ‘standard’ and ‘on-demand’ examination sittings during March and April which produced an overall pass rate of 48%.

Examination technique The following examination techniques were identified as the main areas of improvement for candidates: Did not respond to the command word Many answers were not specific enough and failed to mention the finer details that would have completed the answer. Candidates had particular difficulty with providing enough detail in many answers, and often lacked sufficient knowledge to differentiate between the different parts of a question, writing the wrong answer or repeating themselves within each section. Generally, there was not enough information for a response to an outline question. Provided rote learned responses that did not fit the question A number of candidates provided answers that were actually not required and instead provided information that they did know and hoped that some of the points covered would earn them marks. Did not answer all of the questions Many failed to attempt all the questions. Course providers should ensure that their candidates are sufficiently prepared for the examinations and that they have provided sufficient content for the suggested time allocation in the syllabus.

Command words The following command words are listed in the order identified as being the most challenging for candidates: Outline Most candidates were unable to provide sufficient information when answering ‘outline’ questions. They either used lists or identifies where an ‘outline’ was required. Many candidates relied too heavily on key words or phrases without being able to expand their answers. For example, most would make reference to a “permit” but very few were able to expand their answers if the question was dealing with welding to include a hot work permit. Also many referred to the need for P.P.E but failed to give suitable examples. Explain Whilst ‘explaining’ was a strong point for candidates, it appeared that alarge number of the candidates were not able to obtain sufficient marks due to a lack of breadth and depth of knowledge. Describe Examiners did not observe any problems for candidates responding to the word ‘describe’.

Identify Most candidates were able to give a good range of answers to ‘identify’ questions. Give ‘Give’ appeared to be a command word that candidates were able to respond to well.

Learning outcomes The following learning outcomes have been identified as being the most challenging area of the syllabus for candidates sitting this examination: 1.2:

Explain the hazards inherent in oil and gas arising from the extraction, storage and processing of raw materials and products

An understanding of the hazards and properties of the raw materials and products used in the oil and gas industry is a key part of the basic knowledge required to operate within the industry. Many candidates struggled with answers regarding crude oil hazards and defaulted to describing the generic hazards associated with drilling operations including falling from height. This showed a lack of understanding of the topic and candidates were not able to achieve any meaningful marks possibly due to misunderstanding what the question required. There appeared to be a limited understanding of the meanings of the terms associated with flammability levels. _________________________________________________________________________________ 1.3:

Outline the risk management techniques used in the oil and gas industries

Risk assessment is a key tool in the oil and gas industry and an understanding of the various techniques used is one of the basic skills required to operate within the industry. Few candidates appeared to have a grasp of this fundamental topic. In some cases, their knowledge was extremely limited. Many were unable to define the difference between qualitative and quantitative methods. Many candidates provided a general response that lacked the specific detailed response. Those candidates who decided to use sketches and diagrams in their answer managed to demonstrate their understanding well. __________________________________________________________________________________ 2.5:

Explain the importance of safe plant operation and maintenance of hydrocarbon containing equipment and processes

Asset integrity is an important part of the control measures that need to be implemented to ensure the continued safety of both personnel and plant. Knowledge of the techniques and principles of maintaining the integrity of equipment that contains hydrocarbons is therefore essential. Very few candidates gained marks for this learning outcome. Many gave general answers with regards to slips and trips, housekeeping and nitrogen but not residual nitrogen as required. Many candidates were able to demonstrate knowledge of leaks from valves or isolation or inadvertent start up of equipment without mentioning the consequences. Candidates were able to mention permitto-work (PTW) but were unable to clarify the types of permit required to be used in different circumstances. Course providers and candidates should perhaps give this area some practise.

__________________________________________________________________________________ 3.1:

Outline types of failure modes that may lead to loss of containment from hydrocarbons

An understanding of how equipment such as pipe work, storage tanks, process equipment can fail is a key part of an overall asset integrity control strategy. Loss of containment can lead to injuries to personnel as a result of fire / explosion or pollution of the environment. Many candidates were unable to demonstrate that they understood the concept of a “safe operating envelope”. Some candidates demonstrated a rote-learned response to this question as they failed to demonstrate an understanding of the different failure modes even though they had written the types of failure down. ________________________________________________________________________________ 3.4:

Outline the hazards, risks and controls available for safe containment of hydrocarbons offshore and onshore

This learning outcome concerns the safe storage of hydrocarbons, the types of storage / containment systems in use, knowledge of the consequences of loss of containment and the controls that are required to be implemented is a fundamental knowledge requirement for the oil and gas industry. A number of candidates managed reasonable responses to this question that concerned a boiling liquid expanding vapour explosion (BLEVE). However, a greater number struggled to put the events leading up to a BLEVE into the correct sequence. There were many candidates who simply had insufficient knowledge of the BLEVE sequence to give any kind of meaningful answer.

Conclusion The oil and gas industry is highly hazardous and personnel operating within the industry at all levels need to be fully aware of the hazards and risks that exist within the industry and the controls that are required to be in place to establish and maintain safe operations. The international oil and gas certificate syllabus aims to give candidates sufficient information with regard to the hazards, risks and the controls. It was clear from the candidates’ responses to the examination questions that many did not have sufficient grasp of the entire syllabus. Specifically, candidates should focus on areas on hazards in oil and gas extraction, storage and processing of raw materials, (learning outcome 1.2) risk management techniques (learning outcome 1.3) and safe plant operation (learning outcome 2.5). Working on these highlighted areas of the syllabus should be able to help candidates with their examination technique, specifically, being able to answer all the questions and being able to adapt their knowledge and answer to fit the question asked.
