What is an Offshore Platform
Offshore platforms are used for exploration of Oil and Gas
from under seabed and processing.

5. May 7, 2016 5
OVERVIEW
Offshore platforms are used for
exploration of Oil and Gas from
under Seabed and processing.
The First Offshore platform was
installed in 1947 off the coast of
Louisiana in 6M depth of water.
Today there are over 7,000 Offshore
platforms around the world in water
depths up to 1,850M
 EIL has executed more than 210
offshore platforms

6. May 7, 2016 6
OVERVIEW
Platform size depends on
facilities to be installed on
living quarters, power
generation unit, process
facilities, water injection
facilities, Helipad etc.
Classification of water depths:
 < 350 M- Shallow water
 < 1500 M - Deep water
 > 1500 M- Ultra deep water

TYPES OF OFFSHORE PALTFORM

9. May 7, 2016 93
JACKETED PLATFORM
 Used for moderate water depths up
to 350 M.
 Jackets provides protective layer
around the pipes.
 Typical offshore structure will have
a deck structure containing Cellar
Deck, Main Deck, Top Deck and a
Helideck.
 Piles extend through the seabed into
the soil.
 Cathodic protection used to prevent
corrosion.

10. May 7, 2016 10
JACKETED PLATFORM
 Jacket serves as a template for
the initial driving of the piles.
 Foundation piles are driven
through the inside of the legs
of the jacket structure
 95% of offshore platforms
around the world are Jacket
supported.
 More economical & easy to
expansion

FOUNDATION:
 Loads due to platform
weight and environment.
 Soil investigation
performed in-situ and Lab
test.
 Pile penetrations depends
on platform size and loads,
and soil characteristics, but
normally range from 30
meters to about 100 meters.

ELECTROCHLORINATOR
Usage: To control micro-organisms, control algae growth and
keeps transmission pipes clean.

60. May 7, 2016 60
ELECTROCHLORINATOR CONTINUED…..
Seawater normally contains chloride ion (Cl-
) at a
concentration of from 15,000 to 20,000 ppm. By
electrolysis of seawater, the following reactions
occur:
At anode: 2Cl-
→Cl2 + 2e-
At cathode: 2H2O + 2e-
→2OH-
+ H2
2Na+
+ 2OH-
→2NaOH
Free chlorine (Cl2) generated at the anode
reacts with caustic soda (NaOH)
generated at the cathode and
forms sodium hypochlorite
solution (NaOCl).
Cl2 + 2NaOH → NaOCl + NaCl + H2O
Injection of sodium hypochlorite solution
is very effective to avoid
accumulation of marine life like
shellfish and seaweed etc.
