Topic 47: Effectiveness of using RBD, FTA, ETA and Bayesian Network in modelling failure of equipments in the industry

Reliability Block Diagram (RBD), Fault Tree Analysis (FTA), Event Tree Analysis (ETA) and Bayesian Network have been said to be useful tools in the Safety and Reliability class. How reliable is this? Can we discuss if this is true.

Topic 51: Energy landscape of the future and the risks associated

People say that by 2040 the energy landscape
will definitely change. It is also believed that by 2040 the
global energy demand
will be increased by 30% while the population is
expected to be increased by
25%.
How will these affect the industries? What are the risks associated? Undoubtedly,
fossil fuels will remain the world's
major sources of energy (at least 50% t of the world's energy supplies). That

Topic 46: Is it safe to leave the abandoned oil and and gas wells?

Usually
when the well reaches its economic limit the operator plugs and abandons it.
But the risks and hazards that can happen due to this are neglected. Gas leak
from one of the plugged wells of Elgin gas field shows that abandoned wells can
cause serious threats. With this incident which occurred recently shows that, accidents
can happen even if we have methods to completely seal or plug a well. No human
life was threatened by this accident, but oil and gas leaks from the abandoned
wells can cause serious environmental impacts. Reason for the gas leak in Elgin
field was due to the outdated plugging method used to seal the well by Total.

Topic 45: Managing the risks and issues associated with a depleting reservoir.

In this energy demanding world the need for fossil fuel never declines. Depletion is an unavoidable part of hydrocarbon production and all the reservoirs around the globe faces this. Depletion due to hydrocarbon production can also pose threats that can even make a scar on the earth's face.

2) Fault reactivation

3) Earthquakes

4) Casing damages

5) Formation damage

Topic 44: INHERENT SAFETY IN PROCESS SAFETY MANAGEMENT – A PRACTICAL APPROACH

This topic is a spin-off from my research into redundancy in the oil & gas industry. Thinking this would be a good forum to share from those with experience in the application of this concept.

Topic 43: Unsafe acts/conditions during routine tasks in platforms/offshore and how to avoid them.

Dear all. Most of us are working already or planning join to oil and gas industry as an engineer,so you will do routine jobs frequently. I would like to share incidents/accidents and near misses those happened in the rig where I work and explain reasons ,how to avoid them. I hope you will benefit from this information in you future career.

Topic 42: Potential and Safety Issues concerning Biogas

Biogas is a mixture of various gases from organic gas methane to inorganic gases carbon dioxide, hydrogen, oxygen and so on, which can be produced from a wide range of material. Let's discuss it's potential of being a dependable energy source in the future, and the safety related issues.

Topic 40: Does the value placed on human life have an effect on safety

Discuss the relationship between safety and human life, with respect to the effect of the financial value placed on human life and how an increase or a reduction in  the value placed on human life will affect the general concept of safety management.

Topic 39: PROPOSED EU REGUATION ON OFFSHORE OIL AND GAS SAFETY


At
the last Safety Engineering and Risk Management lecture delivered by the Lawyer
from Maclay Murray and Spence,he touched on an interesting issue. The October
27, 2011 proposal of the EU to introduce binding offshore safety regulations
for the 27 member countries including Norway as a reaction to the Deepwater
Horizon accident the previous year. While I understand that the present regime
of offshore regulations in the UK is the bench mark worldwide, I cannot seem to
agree more with the EU’s proposal to develop uniform regulations guiding the
safety of offshore operations in this part of the world, especially with the EU

Topic 36: Deep Sea Disposal of Oil and Gas Installations – Acceptable risk?

The subject cannot be discussed
without reference to the Brent Spar incident in which Shell, with the UK
government permission, decided to sink the Brent Spar (a redundant oil storage
installation) into the North Sea as a decommission and disposal [1]. Greenpeace,
an Environment protection organization, rallied public support against the
move, culminating in Shell changing their stand even though they had earlier
met all conditions satisfying that the option was environmentally safe.

Topic 35: A different approach to the basic R = P x C formula

I was first introduced to risk assessment during my first degree, as part of a module on Human Factors. I have to make the disclaimer that we only touched semi-quantitative methods of risk assessment; we did not delve into the fully quantitative.

Topic 34: Can the application of Redundancy Increase Safety and Reliability in the oil and gas industry?

A system with a single point of failure is usually made more reliable by the concept of redundancy. Redundant members are added in structural members to reduce the likelihood of failure.

Topic 33: Discuss the future of Biomass as an Alternative Source of Energy- Risk and Challenges

Biomass is currently one of the latest sources of renewable energy. Biomass consists of plant matter that is specifically grown for its ability to generate heat or electricity. Mostly this would mean that Biomass consists of dead plant matter, but plants that are still alive can also generate heat and are therefore also included in the term Biomass.

Topic 32: Decommissioning of aged Platforms and Pipelines in the North Sea - Risks and Challenges


The North Sea’s aged offshore oil and gas platforms and pipelines is
approaching a new phase in its operations during which it will be necessary to
decommission some of them, many of which have been producing oil
and gas for over 30 years.

Topic 31: Prescriptive case, Safety case and the future of Legislation

Like we have established, health, safety and environmental legislation regimes have always been as a result of major accidents. The only time there is the need for new legislation is when there is a major accident. this is rather a faulty pivot for legislation formation because there is no single accident sequence that would ever repeat itself in thesame way. Why is it not possible to achieve a more robust model.

Topic 30: Extending the life of pipeline in the North Sea what are the Safety & Risk challenges

The North Sea is experiencing another wave of technological advancement in the process of extending the life span of Existing pipelines.

A lot of the Pipelines in the North sea have reached or are close to the end of their design life and as usual the business minds who own these assets are taking steps to extend the life of the pipelines instead of just decommisioning, their argument is mainly economic i.e. the CAPEX involved. 

Is this not a potential disaster in the making. Can we properly extend the lives of pipelines and still optimize the safety case
