Integrated safe system of work

Integrated safe system of work is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Integrated safe system of work rather than just read about it. In short: Integrated safe system of work (ISSOW) is used in hazardous industry to request, review, approve and document tasks to be carried out by frontline workers. It integrates permit-to-work, risk assessment and isolation management under a single electronic system, providing safety improvements to the user.

Key takeaways

Integrated safe system of work belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Integrated safe system of work to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Integrated safe system of work from memory before moving on to harder problems.

Reference excerpt

Integrated safe system of work (ISSOW) is used in hazardous industry to request, review, approve and document tasks to be carried out by frontline workers. It integrates permit-to-work, risk assessment and isolation management under a single electronic system, providing safety improvements to the user. Thought to have originated in the North Sea upstream oil industry it was actually used several years before within the Power Industry, ISSoW software now forms a significant segment of the enterprise software market.

History ISSOW has now become synonymous with electronic permit-to-work (e-PTW). The North Sea began adopting several ISSOW suppliers in 2000s, when it was first rolled out to BP's North Everest Platform. From there a number of the major operators in the North Sea oil industry started to adopt this electronic safety system. As of 2012, around 80% of the North Sea use an ISSOW product in some form or another, as it is widely recognised as a key frontline safety system. Between 2001 and present, ISSOW began to be utilised by some of the major operators including, but not limited to, Shell, Exxon Mobil, BG Group, and Chevron. ISSOW systems are used in oil & gas industry around the world.

Worked examples

Example 1 — a first encounter with Integrated safe system of work

Start with the simplest possible case. Write down what Integrated safe system of work claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Integrated safe system of work before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Integrated safe system of work ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Integrated safe system of work

In research: Integrated safe system of work appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Integrated safe system of work in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Integrated safe system of work is common in secondary-school and first-year university syllabi. It links to neighbouring topics Petroleum production, Petroleum stubs, Process safety, so understanding it makes those chapters shorter.
In everyday life: Look for Integrated safe system of work outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
