NEW YORK, Nov. 2, 2006 (PRIMEZONE) -- Overseas Shipholding Group, Inc. (NYSE:OSG), a market leader in providing energy transportation services, today reported results for the third quarter of 2006.

For the quarter ended September 30, 2006, Time Charter Equivalent(1) revenues increased by 31% to $254.8 million from $194.8 million in the third quarter of 2005. TCE revenue performance was the result of strong rates across the Company's VLCC, Aframax, Panamax and Handysize Product Carrier fleets. EBITDA(1) for the third quarter was $135.6 million compared with $135.4 million in the third quarter of 2005. Net income for the quarter ended September 30, 2006 was $90.8 million, or $2.29 per diluted share, compared with $72.1 million, or $1.82 per diluted share, for the third quarter of 2005. The current quarter benefited from gains on vessel sales and sale of securities of $15.8 million or $0.39 per diluted share, compared with $22.4 million, or $0.46 per diluted share, in the same period a year ago. In addition, the current quarter reflects the impact of a $27.0 million, or $0.68 per diluted share, increase in the reserve related to the U.S. Department of Justice investigation as more fully described later in this press release.

For the first nine months ended September 30, 2006, the Company reported a 9% increase in TCE revenues to $751.2 million from $690.5 million in the comparable period of 2005. EBITDA for the first nine months of 2006 decreased to $424.8 million from $535.1 million in the first nine months of 2005 and included the above mentioned increase in the reserve. Net income for the nine month period ended September 30, 2006 was $279.4 million, or $7.06 per diluted share, compared with $351.1 million or $8.89 per diluted share in the comparable 2005 period. The first nine months of 2006 benefited from gains on vessel sales and sale of securities of $21.1 million, or $0.44 per diluted share, compared with $60.7 million, or $1.31 per diluted share, in the comparable period of 2005. In addition, the first nine months of 2006 reflects the impact of a $27.0 million, or $0.68 per diluted share, increase in the reserve related to the U.S. Department of Justice investigation, compared with $4.0 million, or $0.10 per diluted share, in the comparable period of 2005.

Morten Arntzen, President and Chief Executive Officer, stated, "Third quarter TCE revenues were largely the result of a strong spot rate environment in both the crude and product transportation sectors and additions to our product carrier fleet. The increase in operating income before gains and special charges reflects the benefits from OSG's diverse fleet and chartering strategy." Arntzen continued, "Our objective to achieve a market leadership position in the U.S. Flag sector will be realized upon the completion of the Maritrans acquisition. This is another example of our ongoing efforts to transform OSG which began nearly three years ago. Our shareholders will continue to benefit from OSG's leadership position, fleet diversification and spot/time-charter mix that will ensure competitive returns not only in a strong rate environment but throughout all market cycles."

TCE revenues in the third quarter of 2006 for the International Crude Tanker segment were $175.9 million, an increase of 42% quarter-over-quarter, principally due to increases in the daily TCE rates earned on all classes of the segment's vessels. The higher daily rates were partially offset by a decrease in revenue days for VLCCs as a result of increased drydocking and repair days and the sale of three older Aframax tankers. TCE revenues for the International Product Carriers segment increased 25% to $55.0 million from $44.2 million in the year earlier period, principally as a result of an increase in the average TCE rates earned by the Handysize and Panamax Product Carriers, partially offset by an increase in drydocking and repair days. U.S. segment TCE revenues decreased 7% quarter-over-quarter to $19.0 million from $20.4 million in the same period a year ago, principally due to the sale of two crude oil tankers in the fourth quarter of 2005.

Income from vessel operations was $88.9 million in the third quarter of 2006, compared with $82.9 million in the same period a year earlier. For the quarter ended September 30, 2006, total ship operating expenses increased $56.6 million to $176.9 million from $120.3 million in the corresponding quarter in 2005, of which $27.0 million relates to the reserve taken for the U.S. Department of Justice investigation. As a result of the Company expanding its fleet in a capital-efficient manner through sale and leaseback arrangements and time and bareboat charters-in, time and bareboat charter hire expenses increased quarter-over-quarter. Vessel expenses increased quarter-over-quarter principally due to higher crew costs. General and administrative expenses increased principally due to an increase in compensation associated with additional personnel and the change in recognition of targeted cash incentive compensation from an annual to a quarterly basis, expenses incurred in connection with the U.S. Department of Justice investigation and increases in legal, accounting and consulting services.



 RECENT ACTIVITIES AND QUARTERLY HIGHLIGHTS

 -- On September 25, 2006, OSG announced a definitive merger agreement
    with Maritrans Inc. (NYSE:TUG), a leading U.S. Flag crude oil and
    petroleum product shipping company that owns and operates one of the
    largest fleets of double hull vessels serving the East Coast and U.S.
    Gulf Coast trades.  Under the terms of the merger agreement, OSG will
    acquire Maritrans in an all-cash transaction for $37.50 per share.
    On October 16, 2006, the transaction was granted early termination of
    the Hart-Scott-Rodino waiting period.  Consummation of the transaction
    remains subject to other customary conditions, including approval of
    Maritrans' stockholders at a meeting to be held November 28, 2006.

 -- The Company entered into a number of transactions during the quarter
    in furtherance of its strategy to balance the mix of owned and
    chartered-in tonnage and to capitalize on the strong market for
    second-hand tonnage. Fleet acquisition and disposition activity
    during the period resulted in proceeds of vessel sales of $169 million
    resulting in gains taken during the period of $14.3 million.

    -- The Pacific Sapphire, a 1994-built Aframax, was sold on
       July 13, 2006 and the Overseas Keymar, a 1993-built Aframax tanker,
       was sold on August 25, 2006.

    -- On September 6, 2006, the Overseas Crown, a 1996-built VLCC, was
       sold and chartered back.  The gain from the sale was deferred and
       is being recognized over the term of the charter.

    -- The Overseas Hercules and the Overseas Orion, two 2006-built 51,000
       dwt Handysize Product Carriers time chartered-in from Parakou
       Shipping, were delivered on August 16, 2006 and September 14, 2006,
       respectively.  Both vessels immediately commenced time
       charters-out through August 2008 and September 2009, respectively.

    -- On August 16, 2006, the Company agreed to bareboat charter-in three
       50,000 dwt Handysize Product Carriers from Capital Maritime and
       Trading, Inc. for 10 years.  The Overseas Serifos, the Overseas
       Sifnos and the Overseas Kimolos will be constructed at the STX
       Shipyard in Chinhae, South Korea.  The vessels are slated for
       delivery in 2008.

    -- The sale of the Majestic Unity, previously announced on
       June 28, 2006, is expected to close in late November or early
       December 2006, at which time the Company will recognize a gain of
       approximately $28.0 million.

    -- The October 17, 2006 announcement of two Jones Act Product Carriers
       chartered out to Tesoro, brings the total number of OSG's 10-ship
       fleet being built at the Aker Philadelphia Shipyard that have been
       chartered by major oil and refinery companies, to eight.

 -- Future revenues associated with time and bareboat charters as of
    September 30, excluding the Gas segment, totaled $899.8 million up
    from $746.1 million as of December 31, 2005. This amount represented
    30,497 revenue days.

 -- OSG has purchased no shares as of today's earnings release date under
    the $300 million share repurchase program authorized by the Company's
    Board of Directors in June 2006.

 -- On September 12, 2006, the Board declared a $0.25 per share dividend
    to shareholders of record on November 7, 2006, payable on
    November 28, 2006.

 FLEET METRICS AND STATISTICS

 -- As of September 30, 2006, OSG had an operating fleet of 91
    International Flag and U.S. Flag vessels. Fifty-two percent, or 47
    vessels, were owned, compared with 64%, or 59 vessels, as of
    September 30, 2005.

 -- Revenue days in the quarter totaled 7,329, a decrease of 8% over the
    same period a year earlier, principally due to the sale of older
    tankers and an increase in drydock and repair days.

 -- OSG's newbuild program of chartered-in and owned vessels totals 27
    and spans all lines of business and includes four International Flag
    Aframax tankers; nine International Flag Product Carriers; 10 Jones
    Act Product Carriers (collectively representing 1.4 million deadweight
    tons), and four LNG carriers (representing 864,800 cubic meters).

FINANCIAL PROFILE

During 2006, shareholders' equity increased by $242.1 million to $2.1 billion and liquidity, including undrawn bank facilities, increased to more than $2.27 billion. Total long-term debt as of September 30, 2006 was $799.4 million compared with $965.7 million at December 31, 2005. Liquidity adjusted debt to capital was 9.7% as of September 30, 2006, an improvement from 24.5% as of December 31, 2005.

UPDATE ON THE U.S. DEPARTMENT OF JUSTICE INVESTIGATION

In 2004 and the first quarter of 2005, the Company made provisions totaling $10 million for anticipated fines and contributions to environmental protection programs associated with a possible settlement of the U.S. Department of Justice investigation. In the third quarter of 2006, the Company, based on discussions with the U.S. Department of Justice that resumed in August 2006, made an additional $27 million provision for such items. The Company continues to cooperate with the government with the goal of reaching a comprehensive settlement of the investigation. Negotiations with the U.S. Department of Justice are continuing but there can be no assurance that a satisfactory settlement can be achieved. While management believes that the total fines and contributions associated with a possible settlement of the investigation will approximate the total provision of $37 million, no assurance can be given that the provision will be sufficient to cover such items.

MARKET OVERVIEW

Worldwide oil demand during the third quarter of 2006 was approximately 84.2 million barrels per day ("b/d"), an increase of 1.0 million barrels per day, or 1.2%, compared with the third quarter of 2005. This pickup in demand reflects a 3.3% increase in non-OECD countries, partially offset by a decrease of 0.3% in OECD areas. China's energy demand continues to grow, especially in transportation fuels, with third quarter demand increasing by approximately 7.2%, or 480,000 b/d, compared with the year earlier quarter. Middle East demand continued to grow with a third quarter increase of 320,000 b/d, or 5.1%, primarily due to fuel subsidies that have kept prices in Middle East countries significantly below world prices. North American oil demand increased by 0.2% against a third quarter 2005 demand base that reflected the adverse impact from the hurricanes that hit the U.S. Gulf Coast area, dampening demand in both the third and fourth quarters of 2005. Third quarter OECD Europe and OECD Asia demand declined, however, 0.9% and 0.4%, respectively. High prices and bad weather in Japan reduced diesel and gasoline demand while higher natural gas liquid imports, due to lower prices, resulted in a reduction in fuel oil usage. The decline in European demand reflects reduced transportation fuel use, mainly gasoline, as well as a reduction in fuel oil requirements in Italy as power generation needs were met by an increase in lower cost alternatives.

Worldwide oil demand for the first nine months of 2006 increased by 0.8% compared with the first nine months of 2005. Demand declined in all OECD areas by 0.8%, as fuel substitutions combined with lower transportation fuel demand did not offset increases in demand for aviation gasoline. Therefore, non-OECD demand growth of 3% accounted for the growth in worldwide oil consumption during the first nine months of 2006. The non-OECD increase was led by growth of 6.6% in China, 5.4% in the Middle East and 1.2% in Brazil.

Tanker supply has increased by 4.4%, or 13.4 million dwt (4.1 million dwt during the first quarter, 4.6 million dwt in the second quarter and 4.7 million dwt in the third quarter of 2006) from year-end 2005 levels. The largest percentage increase occurred in the Panamax sector, where tonnage has increased by 11.8% since the beginning of the year. VLCCs, on the other hand, experienced the lowest percentage growth at 2.9%. The additional tonnage in each vessel category exerted downward pressure on TCE rates during the first nine months of 2006.

Changing supply patterns in the crude oil market during 2006 have had a favorable impact on tonne-mile demand and fleet utilization rates. Venezuela has reduced its exports to the U.S. by almost 6% through the third quarter, redirecting them to Asia. Crude oil movements from the Atlantic Basin to Asia have also risen significantly this year. Deliveries to Asia from Central and South America increased from 80,000 b/d to about 150,000 b/d. Exports from West Africa to Asia in the first nine months of 2006 increased by almost 30% relative to the same 2005 period, with China accounting for much of this increase. These changes in supply patterns are likely to persist as Venezuela seeks to expand its presence in Asia while continuing to reduce its dependence on the U.S. and as additional investments are made in Africa and South America by Asian national oil companies desiring a secure access to crude supplies.

Third quarter 2006 rates in all vessel categories were higher than rates realized during the same quarter of 2005. Rates in the VLCC and Aframax sectors were favorably impacted by the August announcement of BP's partial shutdown of production in the Prudhoe Bay fields in Alaska due to pipeline corrosion problems. Some U.S. West Coast refineries that utilize Alaskan North Slope ("ANS") crude began to source alternative supplies from the Middle East, increasing demand for VLCCs. New Caspian Sea production transported through the Baku-Tbilisi-Ceyhan ("B-T-C") pipeline to the port of Ceyhan boosted the utilization of Aframaxes operating in the Mediterranean. Third quarter product carrier rates were positively influenced by higher aviation gasoline imports into China, increased movement of products from Asia to the U.S. West Coast and arbitrage opportunities for diesel exports from the U.S. to Europe. Panamax rates benefited from increases in crude oil shipments from the Caribbean to the U.S. West Coast to replace shut-in ANS crude oil production.

Newbuilding vessel prices continued to strengthen during the third quarter of 2006, with increases ranging from 1% for VLCCs and Panamaxes to 4% for Aframaxes relative to the previous quarter. Relative to a year ago, current newbuilding prices have increased 4% for VLCCs, 2% for Aframaxes, 8% for Panamaxes and 10% for Handysize Product Carriers. Prices for second hand vessels also remained strong, with prices for some modern vessels exceeding newbuilding prices as buyers continued to be willing to pay premiums for prompt delivery. Newbuilding prices are likely to remain high as shipyards operate at or near full capacity with orderbooks extending out as far as three to three and one-half years.

                           =========================================

 Consistent with general practice in the shipping industry, the 
 Company uses time charter equivalent revenues, which represents 
 shipping revenues less voyage expenses, as a measure to compare 
 revenue generated from a voyage charter to revenue generated from a 
 time charter.  Time charter equivalent revenues, a non-GAAP measure, 
 provides additional meaningful information in conjunction with 
 shipping revenues, the most directly comparable GAAP measure, 
 because it assists Company management in making decisions regarding 
 the deployment and use of its vessels and in evaluating their 
 financial performance.

APPENDIX 2 -- EBITDA RECONCILIATION

 EBITDA represents operating earnings, which is before interest 
 expense and income taxes, plus other income and depreciation and 
 amortization expense. EBITDA is presented to provide investors with 
 meaningful additional information that management uses to monitor 
 ongoing operating results and evaluate trends over comparative 
 periods. EBITDA should not be considered a substitute for net income 
 or cash flow from operating activities prepared in accordance with 
 accounting principles generally accepted in the United States or as 
 a measure of profitability or liquidity. While EBITDA is frequently 
 used as a measure of operating results and performance, it is not
 necessarily comparable to other similarly titled captions of other
 companies due to differences in methods of calculation.
