General Comments on Examination Paper

A procedure must have a sequence of actions in an order that is achievable, and when item numbers are evident on

the drawing they should be included in the procedure to avoid any element of doubt or confusion. Good

understanding can usually be demonstrated by simple explanations rather than highly complex ones, however an

answer that totals 6 lines for 25 marks is not going to provide sufficient information.

General Comments of Specific Examination Questions

Q1. There was general confusion over when the smaller feed pump would be used, with many candidates stating it

would be used ‘at sea’, to supply the economiser, when the vessel would be using less steam? This is not correct on

many levels and the drawing clearly shows this not to be correct.

Q2. It is of concern that a significant number of candidates could not identify the suction and discharge sides of a

centrifugal pump. Only a few candidates included axial and radial locating of the impeller to the shaft.

Q3. Well answered by most candidates.

Q4. Well answered by most candidates.

Q5. Several candidates stated that the interlock between the bus tie and emergency generator supply breaker, was

to ensure that they both closed at the same time, and opened at the same time? Unfortunately their wording left no

room for grammatical error in what was meant?

Q6. Many items that candidates clearly identified as integral to the operational control of the air automatic valve

were not included in the initial list of items that may cause the stated fault?

Q7. Several candidates only replaced one wear ring, when there are two, with a few removing the impeller without

first gaining access. Some replaced both wear rings without removing either the impeller or casing cover?

General Comments on Examination Paper

This is not an engineering knowledge exam. The answers required are on the drawing, so candidates should relate their answers to the drawing, and not quote ‘normal procedures’ or ‘safety routines’, which don’t relate to the question being asked. More time should be spent reading and understanding the drawing, before answering the question.

General Comments of Specific Examination Questions

Q1. Candidates struggled with the concept that there was more than one option for maintaining the main engine in a warm condition in port, therefor struggled to explain any preferred option.

Q2. Few candidates could identify any casing sections beyond ‘volute’, regardless of terminology.

Q3. Several candidates did not attempt this question, indicating they had not seen a shell expansion plan before, despite it being part of the syllabus.

Q4. Well answered by most candidates.Q5. Well answered by most candidates.Q6. Disappointing that no candidates could demonstrate an understanding of the direction of flow when using generator jacket outlet water, to maintain the main engine in a warm condition when in port. Some ignored the question and simply stated that a pre-heat pump is used, (for 10 marks?), with some stating the pre-heat pump is used in conjunction with the main jacket water pumps? This demonstrates a serious inability to read the drawing. The question requested ‘flow paths’ to demonstrate an understanding of the drawing.Q7. There was a wide variation in answers, between those that has seen a shell expansion before and those that obviously had not. The complications in the repairs should be taken from the drawing, not the procedure or safety aspects involved in undertaking the repair.
