Remedial Options That Might Be Adopted To Mitigate or Prevent Caisson from Hitting and Damaging the
Gas Export Line
Introduction
Most subsea construction works involve risks to human resources such as injuries or death and the system as
well leading to serious losses since they are often installed in places that are rarely visible. Offshore
platforms such as the caisson may develop problems causing severe damages to facilities in the subsea
environment leading to costly downtime in the production circle, environmental issues and dent on
reputation. Companies must put in place proper mechanisms to diagnose the issues leading to malfunctioning
of the caisson that could make it hit and damage the gas export line since such accidents may cause
interruption in service delivery, high cost of repair and sadly, causing danger to crew members and the public
(Cejuela,et al., 2018). Damage to a gas export line may result in to devastating experience on the company
and its environs because it usually escalates to neighboring premises besides the company buildings (Akagi,
2017). It is therefore prudent for an organization to take preventive measures as a critical step while handling
design of caisson structure.
Recommended actions to be taken
Enhanced installation of the ROV solution in place of the traditional IMR (Inspection, Maintenance and
Repair) vessels (Johannessen and Jonassen, 2018)
ROV vessels operate on an advanced dynamic positioning system to guarantee reliability, efficiency and
environmental friendliness. Similarly, it causes a favorable combustive condition and less emission of
exhaust gases. The caisson under this condition will have a longer lifecycle since erosive corrosions are not
emitted to the environment resulting into predictable sea state. Two types of ROVs are used, i.e. construction
ROV in charge of mechanical tasks and observation ROV for real-time monitoring and evaluation of the

assembly process. On the other hand the fuel emission from IMR vessels is a nuisance to the offshore
industry ecological footprint that may cause corrosion of the caisson infrastructure.
The organization should install a restraint designed to stop the caisson together with its internal components
from falling on to the gas line when it fails to replace the caisson fall-arrest clamp (Macey, Eng, and Lueke,
2018, July, 2018).
Conduct regular physical inspection of the condition of the restraint and caisson to ascertain when repair and
maintenance is required.
Recommendations
The organization must put in place a response team with enough resources to cub the effect of the accident
once they occur to prevent mass losses to the company. That is, the most ideal thing to do by the operators is
to protect life and property. To achieve this, the organization must ensure that proper orientation is done to
educate the entire staff on the location of all ignition sources in the plant. These include engines, electrical
devices, gas lights as well as anything that can cause a spark. As a preventive measure, an organization
should follow due process during construction to ensure proper design of underground infrastructure that
meets international standards.
Conclusion
Firms in both offshore and onshore should create a safe, robust and reliable working environment for
effective performance of employees. Despite the efforts put in place to eradicate the danger of caisson hitting
the gas line, the accidents continue to make headlines. Organizations must train employees on the basic
understanding on first aid guidelines while operating in a gas mine to help them deal with gas line accidents.
However, the measures should be economical, efficient and friendly to the environment for them to attract
the attention of local and international stakeholders. Besides, the risk management measures described herein

are short-term focused and one should therefore consider frequent monitoring of the system to replace the
faulty components to guarantee safety while operating in the organization.

TECHNICAL NOTE
Introduction
Operating an integrated system necessitates diagnosis of the nature and scope of failure scenarios for
effective communication of testing and response modalities to reduce risks and salvage costs for the
business. As the system ages, the level of risks also rises and this necessitates more focus and closer
supervision to maintain the technical wellbeing of the company resources in an economical fashion via life
of field. Once installed, any system requires proper monitoring and evaluation to achieve the desired result or
correct mistakes before they escalate to unmanageable levels. Besides, an organization must have a proper
strategy for inspecting the key performance components and reporting the outcome to reduce downtime and
time wastage. As Hofmann, Burke and Zohar (2017) state, a properly conducted inspection of hazardous
processes is a key step towards protecting human life, conserving the environment, maintaining the levels of
production and observing the laws of the land.
1. Failure scenarios
A failure scenario is a recognizable wholesome sequence and combination of likelihood events or conditions
leading to the collapse of a system. It is necessary to identify the failure scenarios because that is the first
step towards eradication of health hazards and minimization of industrial accidents. The following table A
presents some of the failure scenarios that ABCEng Company is likely to face in the production process:
