                       Report of Independent Accountants


To the Participants and Administrator of
The Hanover Companies Retirement Savings Plan


In our opinion, the accompanying statements of net assets available for benefits
and the related statement of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of The Hanover Companies Retirement Savings Plan (the Plan) at December 31, 2000
and 1999, and the changes in net assets available for benefits for the year
ended December 31, 2000, in conformity with accounting principles generally
accepted in the United States of America.  These financial statements are the
responsibility of the Plan's management; our responsibility is to express an
opinion on these financial statements based on our audits.  We conducted our
audits of these statements in accordance with auditing standards generally
accepted in the United States of America which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement.  An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The supplemental schedule identified in
the table of contents is presented for the purpose of additional analysis and
is not a required part of the basic financial statements but is supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974.  The supplemental schedule is the responsibility of the Plan's management.
The supplemental schedule has been subjected to the auditing procedures applied
in the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

The Hanover Companies Retirement Savings Plan
Notes to Financial Statements
December 31, 2000 and 1999
- --------------------------------------------------------------------------------

1.   Description of Plan

     The Hanover Companies Retirement Savings Plan (the Plan) was adopted
     effective January 1, 1994 by Hanover Compressor Company (the Company) and
     replaced the Company's former plan, the Hanover Energy Employee's Savings
     Plan.  The plan custodian is Merrill Lynch.

     The following description of the Plan provides only general information.
     Participants should refer to the Plan agreement for a more complete
     description of the Plan's provisions.

     General
     The Plan is a defined contribution plan covering all employees of the
     Company.  It is subject to the provisions of the Employee Retirement Income
     Security Act of 1974 (ERISA).

     Plan Changes
     Effective May 18, 2000, participants are able to contribute a fixed dollar
     amount or a fixed percentage each pay period.  Previously participants were
     limited to contributing a fixed percentage.  Additionally, participants
     become eligible on the first of the month following six months of
     continuous service.  Previously, a participant became eligible following
     one year of service.

     Contributions
     Participants may contribute up to 20% of their pre-tax compensation, as
     defined.  Participants may also elect to roll over contributions from other
     qualified plans.  The Company may make discretionary contributions to the
     Plan in the form of matching contributions of 35% of each participant's
     contributions for the plan year, up to an annual maximum of $1,000 per
     individual.  Participants who were employed on the last day of the plan
     year or who died, became disabled while an employee of the Company or
     terminated employment after obtaining normal retirement age, as defined,
     during the plan year are eligible for an allocation of discretionary
     employer contributions.  The Company made discretionary contributions of
     $661,382 during the plan year ended December 31, 2000.

     Participant's Accounts
     Each participant's account is credited with the participant's
     contributions, employer contributions and an allocation of Plan earnings
     and forfeitures of terminated participants' nonvested accounts.  All plan
     assets are allocated to individual participant account balances.  The
     benefit to which a participant is entitled is the benefit that can be
     provided from the participant's vested account.

Notes to Financial Statements
December 31, 2000 and 1999
- --------------------------------------------------------------------------------

     Vesting
     Participants are immediately vested in their voluntary contributions plus
     actual earnings thereon.  Participants become vested in the Company's
     contributions at the rate of 20% per year after two years of service.

     Forfeitures
     Forfeited nonvested accounts will be allocated to participants based on
     their contributions.  During the year ended December 31, 2000, forfeited
     nonvested accounts totaling $8,307 were allocated to participants.

     Investment Options
     Upon enrollment in the Plan, participants may direct their contributions
     among 23 different investment options consisting of Hanover Compressor
     Company common stock, common/collective trusts and mutual funds.

     Payment of Benefits
     A participant may elect to withdraw any part of his or her vested account
     upon retirement, termination of employment, death or disability or
     attainment of age 59 1/2. Benefits may be paid by either a lump-sum amount
     equal to the value of his or her account or periodic installments. A lump-
     sum payment is automatically distributed to terminated participants with
     vested balances equal to or less than $5,000. Withdrawals of vested
     balances due to immediate and heavy financial need are also permitted.

     Participant Loans
     Upon written application by a participant, the Plan administrator may make
     loans to participants subject to limitations defined by the Plan. A
     participant loan is a participant-directed investment of his or her account
     which earns a reasonable rate of interest (7.5% to 10.0% on loans
     outstanding during 2000) and is repaid by regular principal and interest
     payments through payroll deductions.

2.   Significant Accounting Policies

     Basis of Accounting
     The financial statements of the Plan are prepared on an accrual basis in
     accordance with accounting principles generally accepted in the United
     States of America.

     Use of Estimates
     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets, liabilities and
     changes therein, and disclosure of

                                      -2-

Notes to Financial Statements

- --------------------------------------------------------------------------------

     contingent assets and liabilities. Actual results could differ from those
     estimates.

     Valuation of Investments
     Shares of mutual funds are valued at quoted market prices which represent
     the net asset value of shares held by the Plan at year-end. The Company
     stock is valued at its quoted market price. Shares of common/collective
     trusts are stated at the fair value of the trusts' underlying net assets as
     determined by the quoted closing price for those securities for which
     market quotations are available or with respect to other assets, fair value
     as determined in good faith by Merrill Lynch. Units of participation in
     funds holding primarily guaranteed investment contracts are valued at the
     contract value of the underlying contracts, which represents contributions
     made under the contracts, plus interest at the contract rate, less funds
     used to pay withdrawals and loans. The cost of guaranteed investment
     contracts approximates fair value. The participants are exposed to credit
     loss in the event of nonperformance by the insurance companies with whom
     the investment contracts are placed. However, the plan administrator does
     not anticipate nonperformance by these companies. Participant loans are
     valued at cost which approximates fair value.

     Investment Income
     Investment income is recorded when earned. The net appreciation in fair
     value of investments includes the gain or loss on investments bought and
     sold during the year as well as the change in fair value.

4.   Plan Termination

     Although it has not expressed any intent to do so, the Company has the
     right under the Plan to discontinue its contribution at any time and to
     terminate the Plan subject to the provisions of ERISA.

5.   Federal Income Tax Status

     The Internal Revenue Service has determined and informed the Company by a
     letter dated December 6, 1995 that the Plan is designed in accordance with
     applicable sections of the Internal Revenue Code (IRC).  The Plan has been
     amended since receiving the determination letter.  However, the Plan
     administrator and the Plan's tax counsel believe that the Plan is designed
     and is currently being operated in compliance with the applicable
     requirements of the IRC.

6.   Party-In-Interest Transactions

     Certain Plan investments are shares of mutual funds and common trusts
     managed by Merrill Lynch.  Merrill Lynch is the trustee as defined by the
     Plan and, therefore, these transactions qualify as party-in-interest
     transactions.  Any purchases and sales of these investments are open market
     transactions at fair market value.  Consequently, such transactions are
     permitted under the provisions of the Plan and are exempt from the
     prohibition of party-in-interest transactions under ERISA.

     During the year ended December 31, 2000, administrative expenses of
     approximately $46,597 were paid by the Company on behalf of the Plan.
