                                   Statement on Form S-4

Eduardo Aleman

Securities and Exchange Commission

Washington, DC 20549

Dear Mr. Aleman:

            On behalf of Dresser-Rand Group Inc. (the "Company") and
Dresser-Rand Company, Dresser-Rand LLC, Dresser-Rand Power LLC, Dresser-Rand
Global Services L.L.C. and D-R Steam LLC (the "Guarantors" and, together with
the Company, the "Registrants"), we are hereby transmitting for filing a
Registration Statement on Form S-4 (the "S-4 Registration Statement").

            As mentioned in the letter dated May 16, 2005 from Edward P. Tolley
III to Mr. Eduardo Aleman at the Securities and Exchange Commission (the
"Commission") withdrawing the registration statement on Form S-4 (File No.
333-122757), we are also responding to those remaining comments set forth in the
comment letter of the staff of the Commission (the "Staff") dated March 11, 2005
(the "comment letter") relating to the Form S-4 that were not previously
addressed during the Staff's review of the Company's Registration Statement on
Form S-1, File No.: 333-124963 (the "S-1 Registration Statement"). The
Registrant cleared all the non-S-4 specific comments in connection with the S-1
and are hereby responding to the remaining 20 comments that are S-4 specific.

            The filing fee for the attached S-4 Registration Statement in the
amount of $39,590.00 was previously paid in connection with the Form S-4
initially filed with the Commission on February 11, 2005 and which was withdrawn
on May 16, 2005.

            The Registrants are registering the exchange offer on the S-4
Registration Statement in reliance on the position of the Securities and
Exchange Commission (the "Commission") enunciated in Exxon Capital Holdings
Corporation, available May 13, 1988 ("Exxon Capital"), Morgan Stanley & Co.,
Incorporated, available June 5, 1991, regarding resales and Shearman & Sterling,
available July 2, 1993 (with respect to the participation of broker-dealers.)
The Registrants have further authorized us to include the following
representations to the Staff of the Commission:

      The Registrants have not entered into any arrangement or understanding
      with any person to distribute the Exchange Notes and, to the best of each
      of the Registrants' information and belief without independent
      investigation, each person participating in the exchange offers is
      acquiring the Exchange Notes in its ordinary course of business and is not
      engaged in, does not intend to engage in, and has no arrangement or
      understanding with any person to participate in the distribution of the
      Exchange Notes. In this regard, the Registrants will disclose to each
      person participating in the exchange offers that if such person is
      participating in the exchange offers for the purpose of distributing the
      Exchange Notes, such person (i) could not rely on the staff position
      enunciated in Exxon Capital or interpretive letters to similar effect and
      (ii) must comply with registration and prospectus delivery requirements of
      the Securities Act in connection with a secondary resale transaction. Each
      Registrant acknowledges that such a secondary resale transaction by such
      person participating in the exchange offers for the purpose of
      distributing the Exchange Notes should be covered by an effective
      registration statement containing the selling securityholder information
      required by Item 507 of Regulation S-K.

      No broker-dealer has entered into any arrangement or understanding with
      the Registrants or an affiliate of the Registrants to distribute the
      Exchange Notes. The Registrants will disclose to each person participating
      in the exchange offers (through the exchange offer prospectus) that any
      broker-dealer who receives the exchange notes for its own account pursuant
      to the applicable exchange offer may be a statutory underwriter and must
      deliver a prospectus meeting the requirements of the Securities Act in
      connection with any resale of those exchange notes. The Registrants will
      also include in the letter of transmittal to be executed by each holder
      participating in the exchange offers that each broker-dealer that receives
      the Exchange Notes for its own account pursuant to the applicable exchange
      offer must acknowledge that it will deliver a prospectus meeting the
      requirements of the Securities Act in connection with any resale of those
      Exchange Notes and that by so acknowledging and delivering a prospectus,
      the broker-dealer will not be deemed to admit that it is an "underwriter"
      within the meaning of the Securities Act.

      Please update the prospectus to disclose whether you know or have reason
      to believe that the estimates are no longer reliable as of the date of the
      prospectus. If you question the accuracy or completeness of estimates made
      by third parties or you know, or have reason to believe, the estimates are
      no longer reliable, you should omit them from the prospectus as investors
      are entitled to rely on statements made in the prospectus.

                  or

            -     have consented to your use of their statistics in your
                  document.

      the Staff's review of the S-1 Registration Statement and the requested
      disclosure has been added to the S-4 Registration Statement.

PROSPECTUS SUMMARY - PAGE 1

4.    Please supplementally tell us the basis for your belief that the company
      has the "largest installed base in the world" of the classes of equipment
      it manufactures.

      The Company has previously responded to this comment in connection with
      the Staff's review of the S-1 Registration Statement and the requested
      disclosure has been added to the S-4 Registration Statement.

5.    If you elect to highlight your competitive strengths and strategy in your
      summary, provide equally prominent and descriptive disclosure of
      competitive weaknesses and risks.

      The Company has previously responded to this comment in connection with
      the Staff's review of the S-1 Registration Statement and the requested
      disclosure has been added to the S-4 Registration Statement.

6.    Under the subheading "The Exchange Notes" please disclose, if true, that
      the old notes represent the only currently outstanding senior subordinated
      indebtedness of the issuer, and that the exchange notes will be equal in
      priority with any old notes that are not exchanged in the exchange offer,

      The Registrants have added the requested disclosure on page 11 in response
      to the Staff's comment.

7.    Please provide us a complete list of countries in which you operate and
      have customers.

8.    If you elect to include this information in your summary, you should
      clarify and balance the disclosure with a summary of cancellation rights
      and any adverse experience with cancellation.

      The Company has previously responded to this comment in connection with
      the Staff's review of the S-1 Registration Statement and the requested
      disclosure has been added to the S-4 Registration Statement.

PROCEDURES FOR TENDERING - PAGE 9

9.    We note from the first bullet point that affiliates might be participating
      in the offer. Tell us the extent of affiliate participation in the
      transaction.

      The Registrants have no reason to believe that affiliates will be
      participating in the offer. The Registrants have removed the reference to
      affiliate participation from the last bullet on page 7 in response to the
      Staff's comment.

SUMMARY HISTORICAL AND PRO FORMA COMBINED FINANCIAL DATA - PAGE 15

10.   We note your disclosures of "Adjustments to expenses due to change in
      ownership" and "Unusual and other items included in EBITDA" in the Summary
      Historical and Pro Forma Combined Financial Data. The nature and intended
      purpose and use of these adjustments is not clear and these amounts could
      be confusing to investors.




Securities and Exchange Commission
January 23, 2006
Page 5

      Please revise your disclosure to remove these amounts. In addition, tell
      us how the adjustments due to change in ownership are reflected in the pro
      forma financial information on pages 40-45.

      The Company has previously responded to this comment in connection with
      the Staff's review of the S-1 Registration Statement and the requested
      disclosure has been added to the S-4 Registration Statement.

11.   In footnote (6) you note a deficiency on a pro forma basis of $32.4
      million for the year ended December 31, 2003. Please note that this
      deficiency does not agree to the corresponding amount presented on Exhibit
      12.1: Computation of Ratio of Earnings to Fixed Charges. Please revise or
      advise us of the reason for the difference.

      The Registrants inform the Staff that the deficiency on a pro forma basis
      for the year ended December 31, 2003 should have been $33.3 million to
      agree with the corresponding amount presented on Exhibit 12.1. The
      Registrants have also revised the disclosure on page 14 and Exhibit 12.1
      to replace the pro forma numbers for the year ended December 31, 2003 with
      pro forma numbers for the year ended December 31, 2004.

RISK FACTORS - PAGE 20
RISKS RELATED TO THE EXCHANGE NOTES - PAGE 20

12.   Add a risk factor highlighting the risk that the company may be unable to
      purchase the notes upon the occurrence of a "change of control" event as
      specified in "Description of the Notes" on page 114 and that note holders
      may not be repaid in full.

      The Registrants have expanded the disclosure on page 24 in response to the
      Staff's comment by adding the requested risk factor entitled "The issuer
      may be unable to purchase the exchange notes upon a change of control."

13.   Please add a risk factor to explain the risks created by the legal
      limitations on the ability of beneficial owners to exercise the rights of
      note holders under the Global Note.

      The Registrants have expanded the disclosure on page 24 in response to the
      Staff's comment by adding the requested risk factor entitled "Because the
      exchange notes are registered in the name of a single registered holder,
      beneficial owners of notes held in book-entry form may have difficulties
      exercising their rights as noteholders."

THE ISSUER AND CERTAIN OF THE GUARANTORS ARE HOLDING COMPANIES ... - PAGE 21

14.   In an appropriate section of your document, quantify the amount of cash
      that the subsidiaries currently could distribute to the note issuer after
      considering all




Securities and Exchange Commission
January 23, 2006
Page 6

      applicable transfer constraints. Also demonstrate the issuer's ability to
      satisfy obligations under the note given the current cash available and
      priority of the notes.

      The Registrants have revised the disclosure on page 70 to indicate that
      the Registrants are not currently aware of any restrictions on the ability
      of the subsidiaries to distribute cash to the issuer. The Registrants
      believe that the covenant compliance section on page 71, showing a fixed
      charge coverage ratio of 3.8:1, demonstrates the issuer's ability to
      satisfy obligations under the notes and its other obligations, regardless
      of priority, in response to the Staff's comment.

THE GUARANTEES MAY NOT BE ENFORCEABLE - PAGE 23

15.   Please reconcile this risk factor with your obligation under Regulation
      S-K Item 601(b)(5) to file an opinion regarding whether the guarantees are
      binding obligations. If counsel cannot opine on this matter, please say so
      explicitly, and explain why counsel cannot opine.

      The Registrants respectfully submit to the Staff that counsel's Exhibit 5
      opinion is already reconciled with the referenced risk factor. Counsel's
      opinion currently covers the binding nature of the guarantees but
      qualifies the opinion in the next succeeding paragraph by reference to the
      effects of fraudulent conveyance laws (among other equitable remedies)
      relating to or affecting creditors' rights generally. As the Staff can
      appreciate, and has appreciated in countless debt offerings and their
      related Exhibit 5 opinions, a court of equity has the power to invoke
      these kinds of laws and remedies. It is for this reason that issuers
      include risk factors like the referenced risk factor and issuers' counsels
      are compelled to add such a qualification whenever an enforceability
      opinion is rendered. As the Staff also is aware, counsel would be unable
      to opine as to enforceability of the guarantees in the absence of the
      existing qualifications.

16.   We note references to the future tense in the last paragraph. Please
      confirm that the guarantees will be outstanding upon the issuance of the
      exchange notes.

      The Registrants confirm that the guarantees will be outstanding upon the
      issuance of the exchange notes. The Registrants have revised the
      disclosure on page 23 in response to the Staff's comment.

RISKS RELATED TO OUR BUSINESS - PAGE 25
WE HAVE IDENTIFIED MATERIAL WEAKNESSES IN OUR INTERNAL CONTROLS ... - PAGE 25

17.   In an appropriate section of your document, disclose in greater detail the
      nature of each of the material weaknesses and reportable conditions
      identified in your disclosure. In this regard, disclose the specific steps
      that the company has taken to remediate each of the material weaknesses.

18.   With a view toward disclosure of past non-compliance, please tell us
      supplementally whether within the past two years the company has been
      removed from a client's approved suppliers database for failing to meet
      the client's safety performance requirements.

      therefore, please disclose that the agreements related to the
      qualification are filed as exhibits.

      the Staff's review of the S-1 Registration Statement and the requested
      disclosure has been added to the S-4 Registration Statement.

20.   We note that as part of the equity purchase agreement with Ingersoll-Rand,
      Ingersoll-Rand was to deliver to Dresser-Rand Holdings, by February 18,
      2005, various estimate statements to determine the post-closing purchase
      price adjustment. Please update us supplementally, and if necessary revise
      to disclose, whether the post-purchase price adjustments have been
      determined.

      The Company has previously responded to this comment in connection with
      the Staff's review of the S-1 Registration Statement and the requested
      disclosure has been added to the S-4 Registration Statement.

21.   Please include an organizational chart illustrating the structure of

      identifiable intangible assets. In addition, disclosure should be provided
      here and in the financial statements of the factors that contributed to

      of goodwill as required by paragraph 51.b. of SFAS 141.

      valuation methodology and significant assumptions and clarify the basis
      for the useful lives of each of the identifiable intangible assets.

      disclosure has been added to the S-4 Registration Statement.

      disclosure has been added to the S-4 Registration Statement.

27.   Disclose how the fair value of the assets and liabilities acquired was

      impractical to do so. For example, you discuss that cost of goods sold as

      the portion or the decrease due to each factor and provide an analysis and
      discussion where necessary.

60.   We note your reservation of the right to amend the terms of the offer.
      Please revise to indicate that, in the event of a material change in the

      please confirm that the expiration date will be included in the final
      prospectus disseminated to security holders and filed pursuant to the
      applicable provisions of Rule 424.

      The Registrants confirm that the offer will be open for at least 20 full
      business days, and that the expiration date will be included in the final
      prospectus disseminated to security holders and filed pursuant to Rule
      424.

62.   We note that the "expiration date" as used in the prospectus means 12:00
      a.m. midnight, but the "expiration date" as used in the exhibits, like the
      Letter of Transmittal, indicates that the exchange offer will expire at
      5:00 p.m. As represented in the exhibits the offer could be open for less
      than 20 full business days due to the 5:00 p.m. expiration time instead of
      an expiration time of midnight on what ultimately may be the twentieth
      business day following commencement. See Question and Answer Eight in
      Exchange Act Release No. 16623 (March 5, 1980). Please confirm that the
      offer will be open at least through midnight on the twentieth business
      day. See Rule 14d-1(g)(3). Reconcile the exhibits to the disclosure in the
      prospectus.

      The Registrants have revised the prospectus and exhibits to conform the
      expiration date to 4:00 p.m. in response to the Staff's comment. In
      accordance with Rule 14d-1(g)(3), the Registrants confirm that the offer
      will be open at least through midnight on the 20th business day (i.e., the
      21st business day).

63.   Refer to the last paragraph under this subcaption. Please advise us as to
      how oral notice of any extension is reasonably calculated to reach
      registered holders of the outstanding notes or otherwise satisfies the
      requirements of Rule 14e-1(d).

      The Registrants have revised the disclosure on page 119 in response to the
      Staff's comment.

      The Registrants respectfully advise the Staff that the prospectus provides
      for prompt issuance of the new notes after the expiration of the offer.

CONSEQUENCES OF FAILURE TO EXCHANGE - PAGE 105

65.   Tell us about the transfer restrictions mentioned in the second paragraph.

      The Registrants have revised the disclosure on page 126 in response to the
      Staff's comment.

NO PERSONAL LIABILITY - PAGE 132

66.   Tell us why the waiver is required. Absent the waiver, why would liability
      exist? Also:

            -     analyze whether this "consideration for the issuance of the
                  notes" is consistent with the Exxon Capital line of no-action
                  letters, and

            -     disclose in this section the Commission's position on
                  indemnification as stated in Regulation S-K Item 512(h).

      The Registrants inform the Staff that they do not believe the waiver is a
      requirement in debt securities offerings and that absent the waiver they
      do not believe liability would necessarily exist. However, they believe
      such a waiver is a customary provision included in such offerings to
      emphasize that such other parties are not obligors on, or guarantors of,
      the notes.

      The Registrants have revised the disclosure on page 153 in response to the
      second bullet of the Staff's comment to add a brief reference to the
      Commission's position on indemnification as stated in Regulation S-K
      512(h), which is also included in the Undertakings section of Part II of
      the S-4 Registration Statement.

      With regard to the first bullet of the Staff's comment, the Registrants
      respectfully inform the Staff that they believe that because the waiver is
      such a minor provision in




Securities and Exchange Commission
January 23, 2006
Page 18

      the indenture, that its inclusion or exclusion has no bearing on the Exxon
      Capital line of no-action letters.

AMENDMENT - PAGE 134

67.   Clarify what you mean in paragraph (1) by the phrase "whose Holders must
      consent to an amendment, supplement or waiver." What is the purpose of the
      clause? In what circumstances can you reduce the principal amount?

      The Registrants respectfully advise the Staff that the phrase "whose
      Holders must consent to an amendment, supplement or waiver" is a provision
      commonly found in indentures meaning that the applicable voting threshold
      of bondholders required to provide consents for an amendment, supplement
      or waiver cannot be reduced except with the consent of the Company and
      each bondholder affected.

WHERE YOU CAN FIND MORE INFORMATION - PAGE 164
