Topic 66: Discuss the risks and challenges involved in working at heights.

Working at height refers to working at a distance above the ground from which a person could fall or any distance liable to cause personal injury. This includes access and egress except by a staircase in a permanent workplace, work at or below ground level, but does not include slips and trips on the level.

Topic 65: Excavation Work in Onshore Pipeline Crowded Areas - Risks and challenges

Excavation is the most fundamental and important element in the construction industry, whether brownfield or greenfield. Basically, four excavation methods are employed during pipeline construction: vertical excavation; horizontal excavation; step trenching and cofferdams.

Topic 64: Discuss the risks and challenges involved in simultanous operations or co-activities in Oil and Gas activities.

Operations with two or more installations and simultaneous operations such as construction and production need appropriate management systems and controls for effective use of resources and to minimise risk.

Topic 63: Discuss the risks and challenges involved in working in a confined space.

Confined space refers to an area which is enclosed with limited access that makes it dangerous to work. An example is the interior of a storage tank which workers may enter for maintenance work but which is not a habitable place.

Topic 60: Discuss the Prevention of Slips, Trips and fall in the work place.

Slips, trips and fall are the most common cause of injury at work. On average, they cause 40 per cent of all reported major injuries and can also lead to other types of serious accidents, for example falls from height. Slips and trips are also the most reported injury to members of the public.

Topic 59: Discuss the Strategy of Fire Safety and Prevention in Offshore Installations

A fire must have three things to ignite and maintain combustion: Fuel, Heat and Oxygen. The basic strategy of fire prevention is to control or isolate sources of fuel and heat in order to prevent combustion. If all three are not present in sufficient quantities a fire will not ignite or a fire will not be able to sustain combustion.

Topic 61: Reactive Hazards

Hazard is defined as a chemical or physical condition that has potential to cause harm to human life, property or the environment and a reactive hazard has potential to initiate a reactive incident. It is an outcome of changes to chemical structure leading to rapid release of energy, heat and gaseous products leading to severe consequences e.g. fire, explosion, or toxic release.

Topic 58: Discuss the safety and environmental issues of unconventional crude oil exploration

There has been an increase in the exploration of unconventional crude oils, which almost equal global conventional oil reserves - from bitumen through to heavy oils. Discuss the safety and environmental issues that arise from their exploration, and possible solutions.

The Macondo incident failed due to the failure of the BOP atop the Macondo well.  The BOP was designed to activate and seal the well if control was lost, even in a “low probability, high impact event”, such as the blowout that occurred the evening of April 20, 2010.  The report released from NAE/NRC, entitled “Macondo Well-Deepwater Horizon Blowout, lessons for improving offshore Drilling Safety”, summarized the known and suspected reasons for why the BOP failed:

Topic 56: How safe is using a Personal Floatation Devices (PFDs) in an offshore platform or Helicopter Travel?

Personal Floatation Devices (PFDs) are protective equipments used on an offshore platform location, on the barge, during boat travel, when travelling in a Helicopter or aeroplane, when fire drills or emergency drills are being conducted or any other time deemed necessary by boat captain, supervisor, pusher or pilot. It is also important to note that proper attention has to be paid on the use of thee PDSs. Examples of these PFDs are life preserver, work vest, life buoy, life raft, survival capsules etc

BOP pressure test incident

Hello ,

I would like to share an incident that happened recently in our rig. 

Facts Pressure Testing of
Shaffer BOP to 15000 psi ongoing. When pressure reached 4700 psi the lower
single ram door was blown off the BOP. Causes It was found that the door
locking mechanism was not engaged, due to human error. Corrective

• Improve safety culture on

• Improve procedures for
maintenance and operation of BOP

Topic 55: Can the applications of Ergonomics Improve Work Place Health and Safety?

Ergonomics is the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data and methods to design in order to optimize human well-being and overall system performance.

Topic 48 (sub-branch): Safety issues during transportation and distribution of oil and gas.

Pipeline is a safe and reliable mode of transportation and distribution of oil and gas. It is also an economical and dependable mode of transportation particularly to the sensitive and strategic areas where vessels cannot access easily. It provides a long term infrastructural option and solves difficulties in handling large volume of products by rail from one loading point to another and therefore reduces minimum transit loss.

Topic 53: Health, safety, environmental and cost issues regarding operation, disposal, and re-use of decommisioned plants

In some years to come a large proportion of the offshore
platform will need to be decommissioned. Can we discuss the health, safety, environmental and cost issues as
regards the operation,disposal, and any potential re-use of decommisioned plants and structures?

Topic 49: Safety issues during drilling operations.

These blogs are the perfect way to develop many and various safety discussions covering large areas of industries. As a student of an MSc in Oil and Gas Engineering I would like to develop a discussion related to safety issues in the sector of well drilling and generally the operations associated with this activity.

Topic 48: Safety issues during transportation and distribution of oil and gas.

Transportation and distribution are two sectors of industry which should also be mentioned regarding safety issues applied there. Many incidents are indicating that there is a need of some improvements in practices applied so far. So, my suggestion is to discuss this topic further.

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
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?

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. 

1) Land subscidence

2) Fault reactivation

3) Earthquakes

4) Casing damages

5) Formation damage

and further more...

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.
