Lesson 3

Reporting Completed Maintenance: Past Simple

Recommended resources

Hello! Welcome back to your English course.

In our last lesson, you learned to use the present continuous tense to describe ongoing actions, like "The engine is running smoothly." This is perfect for reporting what's happening at this very moment.

Today, we will shift our focus from the present to the past. This lesson addresses the learning outcome: Form and use past simple tense to report completed maintenance tasks. This is a fundamental skill for your role in the engine department, as you will need to fill out logbooks, write maintenance reports, and clearly communicate to your supervisors what work you have finished.

We will cover:

  • How to form the past simple tense for regular and irregular verbs.
  • How to create positive statements, negative statements, and questions.
  • How to apply this tense to describe completed maintenance tasks, using examples from real-world maritime documents.

1. Understanding the Past Simple Tense

The past simple tense describes actions or situations that started and finished in the past.

Imagine you see a small leak.

  • Now (Present Continuous): "The valve is leaking."
  • Later (Past Simple): "I repaired the valve."

The first sentence describes an ongoing problem. The second reports a completed action.

To get a clear overview of when and why we use this tense, let's start with a short introductory video.

Learn English Tenses: PAST SIMPLE

The video 'Learn English Tenses: PAST SIMPLE' by Learn English with Rebecca · engVid provides a great introduction. We'll start with the first part to understand the basic concept.

Please watch from the beginning until 01:41. The instructor uses a timeline to explain that the past simple is for actions that are finished and over.

2. Forming the Past Simple: Regular Verbs

Most verbs in English are "regular." This means they follow a simple pattern to form the past tense.

  • Positive Statements: Add -ed to the base verb.

    • check -> checked
    • clean -> cleaned
    • repair -> repaired
      Example: "I checked the lubrication oil level."

  • Negative Statements: Use didn't + the base verb (without -ed).

    • did not check -> didn't check
    • did not clean -> didn't clean
      Example: "He didn't clean the filter yesterday."

  • Questions: Use Did + subject + the base verb (without -ed).

    • Did you check...?
    • Did they clean...?
      Example: "Did you check the pressure gauges?"

The next segment of the video explains these rules, along with important spelling changes and pronunciation.

Learn English Tenses: PAST SIMPLE

Let's continue with the same video to learn the rules for regular verbs in detail.

Watch from 01:41 to 11:25. Focus on three key points: The structure for positive, negative, and question sentences (around 06:20). How the verb returns to its base form in negatives and questions (a common mistake is to say 'didn't checked'). The spelling changes, for example with verbs ending in 'y' like 'study -> studied' (around 11:25).

Test your understanding!

Complete these sentences using the past simple form of the regular verb in parentheses. These are common tasks in an engine room.

  1. Yesterday, the engineers _______ (test) the emergency generator.
  2. I _______ (replace) the old fuel filter this morning.
  3. The rating _______ (not clean) the bilge strainer during his watch.
  4. _______ you _______ (inspect) the purifier as scheduled?
Show answer
  1. Yesterday, the engineers tested the emergency generator.
  2. I replaced the old fuel filter this morning.
  3. The rating didn't clean the bilge strainer during his watch.
  4. Did you inspect the purifier as scheduled?

3. Forming the Past Simple: Irregular Verbs

Many common verbs are "irregular." They do not take the -ed ending in the past simple. Their past forms must be memorized.

Here are a few important irregular verbs for your work:

  • do -> did
  • go -> went
  • see -> saw
  • write -> wrote
  • shut -> shut (this one doesn't change)
  • find -> found

The good news is that the rule for negatives and questions is the same as for regular verbs: use didn't or Did with the base form of the verb.

  • Positive: "I found the problem."
  • Negative: "I didn't find the problem."
  • Question: "Did you find the problem?"

Let's see how this works in the video.

Learn English Tenses: PAST SIMPLE

The next part of the video explains how to use irregular verbs in the past simple.

Watch from 22:00 to 25:57. Notice how the principle of using 'didn't' and 'Did' with the base verb (e.g., 'go', not 'went') is the same for irregular verbs.

Now, let's practice with a mix of regular and irregular verbs.

2020 Past Simple Positive Exercises [101 Online Tests] - Grammarism

The webpage 'Past Simple Positive Exercises' has many examples. We will use a few to test your knowledge.

You don't need to read the whole page. Just look at the list of exercises to get a feel for them. We will use some of these verbs in the practice below.

Test your understanding!

Complete the sentences below with the correct past simple form of the verb in parentheses.

  1. The Chief Engineer _______ (tell) me to overhaul the pump. (irregular)
  2. We _______ (shut) down the auxiliary engine for maintenance. (irregular)
  3. I _______ (write) the work report after I finished the job. (irregular)
  4. The alarm _______ (stop) after he acknowledged it. (regular)
Show answer
  1. The Chief Engineer told me to overhaul the pump.
  2. We shut down the auxiliary engine for maintenance.
  3. I wrote the work report after I finished the job.
  4. The alarm stopped after he acknowledged it.

4. Application: Reporting Completed Maintenance

Now we get to the most important part: using the past simple in your job. You will use it to report completed tasks in logbooks, maintenance forms, and incident reports.

Look at this example of a Preventive Maintenance Schedule (PMS). It lists the jobs you need to do.

Engine Room Preventive Maintenance Schedule (PMS)
This is an example of a real PMS. After completing a task like 'Tappet Clearance And Rocker Gear', you must report it.

To report that you finished this task, you would use the past simple:

"I checked the tappet clearance."
"I adjusted the rocker gear."

Writing a Maintenance Report

Sometimes, you need to describe a sequence of events, especially if there was a problem. This is where writing a short, clear report is essential.

Look at this maintenance report form. The section "DESCRIBE REPAIRS" is where you explain what happened and what you did.

RPZ Annual Test and Maintenance Report Form
A typical report form with a section to describe the repairs performed.

To write this description, you tell a short story using the past simple. Let's look at a professional guide to see how this is done.

How to Write an Incident Report (With Examples)

The article 'How to Write an Incident Report' explains how to structure a report about a past event. The principles are the same for writing a simple maintenance report. We will focus on two sections that show clear examples.

First, read the section 'Crafting an Effective Incident Report'. Notice how the examples in the 'Body' and 'Conclusion' use past simple verbs (e.g., 'walked', 'slipped', 'were called'). Second, read the 'Manufacturing Industry Incident Report Example'. This is very similar to a situation you might find in an engine room. Pay attention to verbs like 'occurred', 'received', 'malfunctioned', 'arrived', and 'shut down'.

Final Practice

Now it's your turn. Imagine this scenario:

Scenario: Yesterday morning, the No. 2 air compressor made a strange noise. You stopped the compressor. You investigated the problem and found a loose connection on the air intake pipe. You tightened the connection. Finally, you started the compressor again and tested it. The noise was gone.

Your Task: Write a short report (3-5 sentences) for a logbook, describing the actions you took. Use the past simple tense. You can start with: "At 09:00 yesterday, the No. 2 air compressor..."

Show an example answer

Here is one possible way to write the report:

At 09:00 yesterday, the No. 2 air compressor made a strange noise. I stopped the unit and investigated the cause. I found a loose connection on the air intake pipe and tightened it. I then started the compressor and confirmed that the noise was gone. The unit operated normally.

Conclusion

Excellent work today. You have covered a critical grammar point for your future career.

  • Key Takeaways:
    • The past simple tense is for actions that started and finished in the past.
    • Regular verbs form the past simple by adding -ed.
    • Irregular verbs have unique past forms that must be memorized.
    • For negatives and questions, we use the helping verb did/didn't with the base form of the main verb.
    • This tense is essential for reporting completed work in logbooks and maintenance reports.

Preview of the next lesson:
We have talked about what is happening now (present continuous) and what was completed (past simple). In the next lesson, we will look to the future. You will learn to use future tenses with 'will' and 'going to' to discuss planned maintenance, such as "I am going to clean the filters tomorrow" or "The Chief Engineer will inspect the engine next week."
