(the "Amendment No. 2) (the Original Schedule 13D, Amendment No. 1, and
Amendment No. 2, together with this Amendment No. 3, are collectively referred
to herein as the "Schedule 13D"). This Amendment No. 3 relates to the common
stock, par value $0.01 per share, of Constar International Inc., a Delaware
corporation (the "Issuer"). Unless the context otherwise requires, references
herein to the "Common Stock" are to such common stock of the Issuer. Capitalized
terms used but not defined herein shall have the meanings given them in the
Original Schedule 13D.


Item 2.  Identity and Background

Item 2 is hereby amended and restated in its entirety as follows:

     (a) This statement is filed by:

          (i) EagleRock Capital Management, LLC ("EagleRock Capital") with
     respect to shares of Common Stock directly beneficially owned by EagleRock
     Institutional Partners, LP, a Delaware limited partnership ("ERIP") and
     EagleRock Master Fund, LP, a limited partnership existing under the laws of
     the Cayman Islands ("ERMF");

          (ii) ERIP with respect to shares of Common Stock directly beneficially
     owned by ERIP;

          (iii) ERMF with respect to shares of Common Stock directly
     beneficially owned by ERMF; and

          (iv) Nader Tavakoli with respect to shares of Common Stock
     beneficially owned by EagleRock Capital, ERIP, and ERMF.

     EagleRock Capital, ERIP, ERMF, and Mr. Tavakoli (collectively, the
"Reporting Persons") expressly disclaim beneficial ownership of securities
directly beneficially owned by any person or entity other than, to the extent of
any pecuniary interest therein, the various accounts under the Reporting
Persons' management and control.

     (b) The address of the principal business office of the Reporting Persons
is 24 West 40th St., 10th Floor, New York, NY 10018.

     (c) The principal business of EagleRock Capital is to serve as investment
manager to a variety of private investment funds, including ERIP and ERMF, and
to control the investing and trading in securities by these private investment
funds. The principal business of each of ERIP and ERMF is to serve as a private
investment limited partnership. The principal business of Mr. Tavakoli is to
serve as a principal of EagleRock Capital.

     (d) None of the Reporting Persons has, during the last five years, been
convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors).

                                  Page 6 of 9


     (e) None of the Reporting Persons has, during the last five years, been a
party to a civil proceeding of a judicial or administrative body of competent
jurisdiction and as a result of such proceeding was or is subject to a judgment,
decree or final order enjoining future violations of, or prohibiting or
mandating activities subject to, federal or state securities laws or finding any
violation with respect to such laws.

     (f) EagleRock Capital is a Delaware limited liability company. ERIP is a
Delaware limited partnership. ERMF is a limited partnership existing under the
laws of the Cayman Islands. Mr. Tavakoli is a United States Citizen.


Item 3.  Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended and restated in its entirety as follows:

     The Reporting Persons expended an aggregate of approximately $8,216,076 of
their investment capital to purchase the 2,171,482 shares of Common Stock. Such
transactions were effected in open market purchases and acquired in the ordinary
course of business and are held by ERIP and ERMF in commingled margin accounts
maintained at Merrill Lynch and Morgan Stanley, respectively, which may extend
margin credit to the Reporting Persons as and when required to open or carry
positions in the margin accounts, subject to applicable federal margin
regulations, stock exchange rules and credit policies. In such instances, the
positions held in the margin accounts are pledged as collateral security for the
repayment of debit balances in the accounts. The margin accounts may from time
to time have debit balances. Since other securities are held in the margin
accounts, it is not possible to determine the amounts, if any, of margin used to
purchase the shares of Common Stock reported herein.


Item 5.  Interest in Securities of the Issuer.

Item 5 is hereby amended and restated in its entirety as follows:

     (a) As of the close of business on February 13, 2009, the Reporting Persons
beneficially own an aggregate of 2,171,482 shares of Common Stock, representing
approximately 16.8% of the shares of Common Stock outstanding. The percentages
used herein are based upon the 12,952,309 shares of Common Stock reported to be
outstanding as of November 10, 2008 by the Issuer in its Quarterly Report on
Form 10-Q filed with the Securities and Exchange Commission on November 14,
2008.

     EagleRock Capital and Mr. Tavakoli own directly no shares of Common Stock.
Pursuant to an investment management agreement, EagleRock Capital maintains
investment and voting power with respect to securities held by ERIP and ERMF.
Mr. Tavakoli is the manager of EagleRock Capital and therefore controls its
investment decisions. By reason of the provisions of Rule 13d-3 of the Act, as
amended, each of EagleRock Capital and Mr. Tavakoli may be deemed to own
beneficially 2,171,482 shares of Common Stock (constituting approximately 16.8%
of the shares of Common Stock outstanding).

                                  Page 7 of 9
