Answer:
(b). and (c).
Explanation:
Offshore oil production involves drilling below the sea bed level and involves exploration and extraction of petroleum.
The production also applies to drilling beneath lakes or inshore waters.
The major challenges which it presents are in the form of difficulty of assembling human resources at such a site and movement of supplies and transportation i.e logistics.
Off shore oil production thereby involves huge cost and immense efforts.
Thus, off shore oil production presents both human resources and logistics challenges.
Answer:
a. atmospheric
Explanation:
According to the author of the textbook, offshore oil production presents atmospheric challenges.
The harsh offshore atmospheres which pose technical challenges for offshore drilling machinery are the reason for the risk. Extreme weather, snow and winds carry risks to the usability of the rigs, and their gap from the ground makes it more difficult for increased rescue workers to attain the areas quickly in emergencies.
