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

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