Reconsider the lifting operations in Example 10.6, but consider the whole operation including the worker onboard the ship, the crane operator, and the worker on the quay who positions the containers and removes the hooks.

Reconsider the lifting operations in Example 10.6, but consider the whole operation including the worker onboard the ship, the crane operator, and the worker on the quay who positions the containers and removes the hooks. Note the assumptions you have to make to carry out the analysis. (a) Break down the job into a sequence…
Construct an event tree with “Aircraft about to enter runway” as the hazardous event and with “Accident” or “No accident” as the end events in the event tree

At an airport, there are a number of barriers in place to prevent an aircraft from entering a runway while there is another aircraft about to take off or land. For a collision between two aircraft to happen, all the following barriers must fail: First the pilot should stop at a designated place and wait…
Determine the mean time to the first system failure, i.e. the mean time until unchlorinated water is supplied to the customers for the first time after time t = 0.

The water chlorination system of a small town has two separate pipelines, each with a pump which supply chlorine to the water at prescribed rates. The two pumps are denoted A and B respectively. During normal operation, both pumps are functioning, and thus are sharing the load. In this case, each pump is operated on…
Draw an event tree with hazardous event “Equipment being lifted” and with two end events

In a process plant, a crane is being used to lift new equipment to be installed in the plant. The lift consists of the crane wire, the crane hook, and the strap securing the equipment so it can be lifted. Further, the wire is equipped with two braking systems: an engine brake that is normally…
Prepare an event tree with hazardous event (top event) “Gas released” and end events “Operator killed” and “Operator not killed”

In a process plant, flammable gas that is accidentally released can be detected by an automatic gas detection system or by a process operator working in the area. The process operator can only detect gas if she is present in the area where the gas is released. There are several operators working in the plant,…

Establish a hazard–barrier matrix showing which barriers protect against which hazardous events.

NORSOK Standard S-001 contains a description of the most important barriers/barrier systems on offshore installations in Norway (Section 5 through 24). The most important hazardous events that these barriers shall protect against are the following: Releases of oil/gas from the process plant. Releases of oil/gas from risers and pipelines. Releases of oil/gas from storage. Releases…
How can we take these effects into account in the THERP method

a task analysis was performed for fixing your bicycle. Perform a SHERPA analysis of some of the tasks required to do this. The worksheet in Figure 15.6 may be used, but you may delimit the analysis to cover only the first six columns in the worksheet. it is stated that operators typically are assumed to…
calculate the probability that at least one of the operators will detect a gas release.

In a gas processing plant, releases of flammable gas may occur and early detection is important. There is an automatic gas detection system, but in addition, the gas release may be detected by two operators working in the area. The following information is provided: Each operator spends 30% of her time in the area and…
Consider the different aspects of risk and discuss how these different situations will affect the different aspects of risk (increase/decrease/no change) and whether any changes will be small or large.

Different aspects of risk are considered. In a shipping company, the following situations arise: New regulations are introduced that imply stricter requirements to life-saving equipment on ships (e.g. lifeboats, liferafts, survival suits). This applies to all new ships that are being built. The company has recently received two new-built ships and put these into operation.…
