DeepSea is a natural gas extraction company that retrieves natural
gas from rock formations beneath the seabed. This gas is then transported through its
extensive pipeline network to a bottling plant, located at the sea surface, for processing.
The gas in rock formations is pressurized, enabling it to flow to the surface and reach the
bottling plant. Yet, excessive pressure can cause bursts in the pipeline, leading to
uncontrolled gas release, known as blowout. A blowout carries a staggering cost,
encompassing not only environmental damage but also reputation loss and financial losses
totaling crores of rupees. Additionally, the impacted section of the pipeline requires a
complete replacement.
Industry safety regulations divide the pipeline network into
three levels: Level 3 is the part under the seabed, Level 2 is the part above the seabed but
in the deep sea, while Level 1 is near the surface. The safety regulations require multiple
blowout preventer valves, from now on simply referred to as valves, to be placed at
the three different levels of the pipeline network. The valves are normally kept closed, but
when the pressure in any part of the pipeline rises beyond a critical level, nearby valves
are opened remotely to release the pressure in a controlled manner to prevent blowout. The
number of valves across the pipeline helps localize the pressure release, with a greater
number of valves providing a backup mechanism, helping in improving pressure localization in
case of a blowout. Given that the valves themselves can occasionally malfunction and not
release the pressure when needed, using a higher number of valves ensures that a
malfunctioning valve can seek the safety of a nearby functioning valve.
A valve can
malfunction in two ways: it may fail to release pressure when needed, as previously
mentioned, or it can leak gas during regular operation, resulting in unwanted losses. When a
valve malfunctions, it necessitates manual replacement.
In the DeepSea Network, 30%
of the valves are located at Level 3, which is the deepest level. The remaining valves are
evenly distributed between the top two levels. These valves are critical to ensuring safety
and are exclusively supplied by GoValve, a highly specialized manufacturer that holds a
monopoly in the country’s market.
Question 7 : GoValve has recently proposed a maintenance package for the valves to DeepSea, which
includes a clause that whenever a valve at Level 3 malfunctions, all valves at that
level will be replaced. Accepting the clause will cost a significant premium. The
management of DeepSea have the following pieces of additional information under
consideration:
A. The valves are known to be prone to malfunction.
B. Any
malfunction in one valve often results in leakage from the neighboring valves.
C.
GoValve is ready to negotiate a discount if the clause is accepted.
D. Replacing the
valves at Level 3 is a very difficult job, which is best done by GoValve.
E. The
chances of pressure buildups are higher near the seabed.
Which of the
following combinations, of the above pieces of additional information, will help the
management of DeepSea the MOST in accepting the clause?
