Context: Kakinada terminal will be India’s first, and possibly the world’s second, GBS LNG terminal, offering round-the-year operations.
GBS –Understanding Terminology
- GBS is described as a concrete structure with a ballast section at the bottom, which, when filled with gravel, makes the structure heavy enough to sink and sit on the seabed.
- GBS units rely on gravity for stability rather than being bolted or held by cables.
Advantages of GBS units:
- Safer working environment due to stability in sea wave volatility.
- No additional pressure on ports as it has an offshore landfall point.
- Longer economic life and potential relocation to new markets if needed.
- Attractive proposition for international financiers due to longer asset life and flexibility.
Comparison with other LNG terminals:
- GBS units are estimated to have lower project costs compared to floating storage regasification units (FSRUs), and land-based terminals due to fewer overheads like breakwater construction and ongoing dredging expenses.
