NEW YORK (CNNMoney.com) -- Yet another energy outfit is hoping to tap into a hot market with an initial public offering.

Valero GP Holdings is the holding company for Valero LP (Charts), which operates independent terminals and petroleum pipelines in the United States and around the world. This coming week, it's looking to go public.

Valero GP itself is owned by subsidiaries of refinery giant Valero Energy (Charts). An estimated 17.25 million units of Valero GP are expected to be sold for between $22 and $24 a share. (Each unit represents limited liability company interest.)

Valero GP plans to trade on the New York Stock Exchange under the symbol "VEH."

Here's a look at the other IPOs on tap for this week:

Allied World Insurance plans to sell 8.8 million shares at an estimated price of $34 to $37 a share, and list on the New York Stock Exchange under the symbol "AWH."

The Bermuda-based insurer underwrites property and casualty insurance through operations in Bermuda, the United States, Ireland and the United Kingdom. It also is involved in reinsurance.

It intends to use the money raised from the offering to pay back loans and for general business purposes.
