* OSN TV unit operates in North Africa and the Middle East
* Valued last year at $4.3 bln by Arqaam Capital
* KIPCO hopes listing completed by the end of 2014 (Adds background, details on OSN)
KUWAIT, March 31 (Reuters) - Kuwait Projects Co (KIPCO), the Gulf state's largest listed investment company, plans to start the process for an initial public offering (IPO) of shares by its pay-television unit OSN within weeks, it said on Monday
Deputy chairman Faisal al-Ayyar said he hoped the bourse listing would be completed by the end of this year, and that he was looking at a primary listing in London.
"We start the process within a few weeks," Ayyar told reporters on the sidelines of KIPCO's annual general meeting.
Asked where OSN would list, he said: "It depends on how much corporate governance is needed, and how much is needed as a stake to be sold ... all things are tilted towards London, but not as GDR (global depositary receipts), as a primary listing."
He did not say which banks were involved in the process.
The OSN network operates in the Middle East and North Africa. Ayyar said it currently had around $700 million in annual revenues which he expects to double over the next three years.
KIPCO said in February the network had nearly a million subscribers.
KIPCO, an investment house with stakes in media, industrial, financial and real estate companies, said in June it was planning to list OSN. It currently has a 60.5 percent stake.
KIPCO hired financial group Rothschild to advise on the IPO.
Last year brokerage Arqaam Capital said it had raised its valuation of OSN to $4.3 billion from the previous estimate of $2.5 billion, an increase of 72 percent.
Ayyar said KIPCO expected group revenues and profit to grow by a double digit percentage each year over the next three years.
KIPCO reported a 75 percent rise in fourth-quarter net profit in February, saying OSN had performed strongly.
Net profit in the three months to the end of December was 14 million dinars ($49.7 million), compared with 8 million dinars in the same period the year before. (Reporting by Sylvia Westall; Editing by Yara Bayoumy and Mark Potter)
