Question

Match the platforms (GROUP I) with appropriate support systems (GROUP II). 
 

• A. P – IV, Q – III, R – I, S – II
• B. P – II, Q – III, R – I, S – IV
• C. P – III, Q – I, R – IV, S – II
• D. P – I, Q – IV, R – II, S – III

Hint:

Each offshore platform requires a specific type of mooring system depending on its structure and operational conditions. TLPs use column stabilizers, FPSOs use turret mooring, and semi-submersibles are supported by catenary mooring.

Answer 1

The Correct Option is A

Here's the correct matching based on platform types and their support systems:
- P – III: A semi-submersible platform is supported by catenary mooring, which allows it to be anchored to the seabed with chains or cables. The platform floats on the water's surface.
- Q – I: A spar platform is typically anchored to the seabed by tethers, which are used to keep the platform in place in deep water.
- R – IV: A tension leg platform (TLP) is stabilized using column stabilized units, which are anchored by vertical tendons or tethers.
- S – II: An FPSO (Floating Production Storage and Offloading unit) uses turret mooring, which allows the unit to rotate freely and maintain position while producing and storing oil or gas.
Thus, the correct matching is option (C).
