Item 1. Security and Issuer

     The title of the class of equity securities to which this Schedule 13D relates is ordinary shares of the nominal (par) value of 0.56 Euro (€0.56) each (the “Ordinary Shares”) of N.V. Koninklijke Nederlandsche Petroleum Maatschappij (Royal Dutch Petroleum Company), a company organized pursuant to the laws of the Netherlands (“Royal Dutch”). The address of the principal executive offices of Royal Dutch is 30, Carel van Bylandtlaan, 2596 HR The Hague, The Netherlands.

Item 2. Identity and Background

     The name of the person filing this statement is Royal Dutch Shell plc, a public limited company organized pursuant to the laws of England and Wales (“Royal Dutch Shell”).

     On May 19, 2005, Royal Dutch Shell commenced an exchange offer for all of the Ordinary Shares of Royal Dutch (the “Offer”). Concurrently, the “Shell” Transport and Trading Company, p.l.c. (“Shell Transport”) published definitive documentation with respect to a scheme of arrangement under English law of Shell Transport (the “Scheme”).

     On July 20, 2005, Royal Dutch Shell, Royal Dutch and Shell Transport announced that all conditions to the Offer and the Scheme had been satisfied or waived and that Royal Dutch Shell had become the parent company of Royal Dutch, Shell Transport and, through Royal Dutch and Shell Transport, of the Royal Dutch/Shell Group of Companies (the “Group”; collectively, Royal Dutch Shell, Royal Dutch, Shell Transport and the Group are referred to as the “Shell Group”).

     On July 20, 2005, Royal Dutch Shell also announced that it had commenced a subsequent offer acceptance period (the “Subsequent Offer Acceptance Period”; the Offer, including the Subsequent Offer Acceptance Period, the “Exchange Offer” and together with the Scheme, the “Transaction”) expiring on August 9, 2005. During this period, holders of Ordinary Shares of Royal Dutch are permitted to tender any remaining Ordinary Shares of Royal Dutch as described in the prospectus dated May 19, 2005 in respect of the Exchange Offer (the “Prospectus”). The Subsequent Offer Acceptance Period is not an extension of the Offer, in respect of which exchanges of Royal Dutch Shell shares for Ordinary Shares of Royal Dutch tendered were settled on or before July 25, 2005. During the Subsequent Offer Acceptance Period there are no withdrawal rights either for Royal Dutch Shares tendered for exchange in the Offer or for those tendered during the Subsequent Offer Acceptance Period. Royal Dutch Shell will promptly accept for exchange any Ordinary Shares of Royal Dutch tendered during the Subsequent Offer Acceptance Period at the same exchange ratio as in the Offer (as described below).

     Except as described above and any obligations assumed by Royal Dutch Shell in connection with becoming the parent company of the Shell Group, Royal Dutch Shell has not engaged in any operational activities since its incorporation on February 5, 2002. The primary object of Royal Dutch Shell is to carry on the business of a holding company.

     The address of the principal business and the principal office of Royal Dutch Shell is 30, Carel van Bylandtlaan, 2596 HR The Hague, The Netherlands. Set forth in Schedule A attached hereto, which is incorporated herein by reference, is the name, citizenship, residence or business address and present principal occupation or employment (and the name, principal business and address of any corporation or other organization in which such employment is conducted) of each of Royal Dutch Shell’s directors and executive officers. During the last five years, neither Royal Dutch Shell nor, to Royal Dutch Shell’s knowledge, any person named in Schedule A hereto, has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors). During the last five years, neither Royal Dutch Shell nor, to Royal Dutch Shell’s knowledge, any person named in Schedule A hereto was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which such person 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.

Item 3. Source and Amount of Funds or Other Consideration

     Royal Dutch Shell has acquired beneficial ownership of 1,961,615,975 Ordinary Shares of Royal Dutch, or 94.79% of the Ordinary Shares of Royal Dutch. This includes (i) all Ordinary Shares exchanged by Royal Dutch Shell for Royal Dutch Shell shares in the Offer and (ii) all Ordinary Shares tendered prior to the filing hereof in the Subsequent Offer Acceptance Period. Royal Dutch Shell did not exchange and does not intend to seek delivery of, and therefore disclaims beneficial ownership of, 2,982,288 Ordinary Shares in New York registry
form tendered in the Offer via the guaranteed delivery procedure not delivered to the U.S. exchange agent in respect of the Offer as required by the Prospectus. Under the terms of the Exchange Offer, (a) for every Ordinary Share or Royal Dutch held in New York registry form tendered in the Exchange Offer, the tendering shareholder received one Royal Dutch Shell Class A American depository receipt (each, a “Class A ADR”) representing two Royal Dutch Shell Class A ordinary shares of Royal Dutch (each, a “Class A Share”) and (b) for every Ordinary Share of Royal Dutch held in bearer or Hague registry form tendered in the Exchange Offer, the tendering shareholder received two Class A Shares. Other than the issuance of Class A Shares and Class A ADRs, no consideration was paid to shareholders of Royal Dutch in connection with the Exchange Offer.

Item 4. Purpose of Transaction

     Pursuant to the Exchange Offer, Royal Dutch Shell offered to acquire all of the Ordinary Shares of Royal Dutch. Upon consummation of the Offer and the Scheme, Royal Dutch Shell became the holding company of both Royal Dutch and Shell Transport and, through Royal Dutch and Shell Transport, the Group.

     (a) As described above, on July 20, 2005, Royal Dutch Shell commenced the Subsequent Offer Acceptance Period that will expire on August 9, 2005.

In addition, as indicated in the Prospectus and the announcements of July 20, 2005, Royal Dutch Shell reserves the right to use any legally permitted method to obtain 100% of the Ordinary Shares of Royal Dutch. This could include a squeeze out procedure, engaging in one or more corporate restructuring transactions, such as a merger, liquidation, transfer of assets or conversion of Royal Dutch into another form or corporate entity, or changing the Royal Dutch articles of association to alter the corporate or capital structure in a manner beneficial to Royal Dutch Shell. Further, Royal Dutch Shell could engage in one or more transactions with minority holders of Ordinary Shares of Royal Dutch which may include public or private exchanges, tender offers or purchases for consideration consisting of Royal Dutch Shell shares, other securities or cash.

     If the number of Ordinary Shares of Royal Dutch that have been acquired in the Exchange Offer represent at least 95% of the issued share capital of Royal Dutch that is then outstanding, Royal Dutch Shell expects, but is not obligated, to initiate squeeze-out proceedings in accordance with Article 2:92a of the Dutch Civil Code with a view to acquiring all Ordinary Shares of Royal Dutch held by minority holders of Ordinary Shares of Royal Dutch against payment of a price in cash to be determined by a Dutch court. Under these proceedings, the price paid for Ordinary Shares of Royal Dutch held by minority holders of Ordinary Shares of Royal Dutch will be determined by a Dutch court, which could appoint experts to advise it on the value of Ordinary Shares of Royal Dutch. Further, if the squeeze-out proceedings are successful, the minority holders of Ordinary Shares of Royal Dutch will be required to transfer their Ordinary Shares of Royal Dutch against payment of the price determined. Also, upon payment of the amount required to purchase the Ordinary Shares of Royal Dutch into a prescribed bank account, Royal Dutch Shell would become the holder of the Ordinary Shares of Royal Dutch by operation of law. The only remaining right of the minority holders of Ordinary Shares of Royal Dutch would be to receive payment for their Ordinary Shares of Royal Dutch.

     (b) Other than the unification of Royal Dutch and Shell Transport under Royal Dutch Shell pursuant to the Exchange Offer and the Scheme and any transactions described in the following sentence, no other extraordinary corporate transaction with respect to Royal Dutch is currently planned. As indicated in the Prospectus and the announcements of July 20, 2005, Royal Dutch Shell reserves the right to use any legally permitted method to obtain 100% of the Ordinary Shares of Royal Dutch. This could include a squeeze out procedure, engaging in one or more corporate restructuring transactions, such as a merger, liquidation, transfer of assets or conversion of Royal Dutch into another form or corporate entity, or changing the Royal Dutch articles of association to alter the corporate or capital structure in a manner beneficial to Royal Dutch Shell. Further, Royal Dutch Shell could engage in one or more transactions with minority holders of Ordinary Shares of Royal Dutch which may include public or private exchanges, tender offers or purchases for consideration consisting of Royal Dutch Shell shares, other securities or cash.

     (c) No sale or transfer of a material amount of assets of Royal Dutch or any of its subsidiaries is currently planned or proposed.

     (d) There are no plans or proposals to change the present board of directors or management of Royal Dutch (including no plans or proposals to change the number or term of directors or to fill any existing vacancies on the board).

     (e) No material change is currently planned or proposed in the present capitalization of Royal Dutch. While no determination has yet been made as to the future dividend policy of Royal Dutch, Royal Dutch may change its dividend policy. The holders of Ordinary Shares of Royal Dutch should be aware that there can be no assurance that Royal Dutch will continue to declare dividends to the shareholders at the same rate and/or frequency in the future as it has in the past, or that any dividends declared on the Ordinary Shares of Royal Dutch will be equivalent (giving effect to the exchange ratio) to dividends paid on Royal Dutch Shell shares.

     (f) Except as described above in (a) to (e), no material change in Royal Dutch’s business or corporate structure is currently planned or proposed.

     (g) Other than the actions described in (a) above, no changes to Royal Dutch’s articles of association, articles of incorporation or other actions which may impede the acquisition of control of Royal Dutch by any person are currently planned or proposed.

     (h) Royal Dutch Shell intends to request that Royal Dutch seeks to delist the Ordinary Shares of Royal Dutch from Euronext Amsterdam and from the New York Stock Exchange as soon as reasonably practicable in accordance with applicable rules. The Ordinary Shares of Royal Dutch have been removed from the Official List of the UK Listing Authority and from trading on the London Stock Exchange with effect from 20 July 2005.

     (i) After the end of the Subsequent Offer Acceptance Period, the Ordinary Shares of Royal Dutch may become eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act.

     (j) Other than as described above, Royal Dutch Shell currently has no plans or proposals that relate to, or would result in, any of the matters listed in Items 4(a) through 4(i) of Schedule 13D (although Royal Dutch Shell reserves the right to develop such plans).

Item 5. Interest in Securities of Royal Dutch

     (a) Royal Dutch Shell has acquired beneficial ownership of 1,961,615,975 Ordinary Shares of Royal Dutch, or 94.79% of the Ordinary Shares of Royal Dutch

(the “Subject Shares”). This includes (i) all Ordinary Shares exchanged by Royal Dutch Shell for Royal Dutch Shell shares in the Offer and (ii) all Ordinary Shares tendered prior to the filing hereof in the Subsequent Offer Acceptance Period. Royal Dutch Shell did not exchange and does not intend to seek delivery of, and therefore disclaims beneficial ownership of, 2,982,288 Ordinary Shares in New York registry form tendered in the Offer via the guaranteed delivery procedure not delivered to the U.S. exchange agent in respect of the Offer as required by the Prospectus.

     (b) Upon settlement of any exchanges made during the Subsequent Offer Acceptance Period that have not yet settled, Royal Dutch Shell will have the sole power to vote and to direct the vote, and the sole power to dispose and to direct the disposition of, the Subject Shares.

     (c) Except as described in this Schedule 13D and tenders of Ordinary Shares of Royal Dutch in the Exchange Offer by the persons identified in Schedule A, there have been no transactions in the Ordinary Shares of Royal Dutch effected by Royal Dutch Shell or, to Royal Dutch Shell’s knowledge, any person identified in Schedule A during the past sixty days other than:

     (i) Jeroen Van der Veer: Mr. Van der Veer received a notional number of 116 Ordinary Shares of Royal Dutch as part of the Deferred Bonus Plan on June 16, 2005 and 1189 Ordinary Shares of Royal Dutch as part of the Long Term Incentive Plan (the “Plan”) on June 15, 2005, which shares would be purchased when Mr. Van der Veer’s rights with respect to those shares vest.

     (ii) Malcolm Brinded: Mr. Brinded received a notional number of 422 Ordinary Shares of Royal Dutch as part of the Plan on June 15, 2005, which shares would be purchased when Mr. Brinded’s rights with respect to those shares vest.

     (iii) Rob Routs: Mr. Routs received a notional number of 822 Ordinary Shares of Royal Dutch as part of the Plan on June 15, 2005, which shares would be purchased when Mr. Rout’s rights with respect to those shares vest.

     (iv) Linda Cook: Ms. Cook received a notional number of 146 Ordinary Shares of Royal Dutch as part of the Restricted Stock Plan on June 16, 2005, which shares would be purchased when Ms. Cook’s rights with respect to those shares vest. In accordance with the terms of the Shell Provident Fund, in light of adjustments in currency exchange rates and market price of Ordinary Shares of Royal Dutch, the notional amount of Ordinary Shares of Royal Dutch held by Ms. Cook in such Fund decreased by 4 and 26 on June 1 and July 1, 2005, respectively, and increased by 91 on June 16, 2005.

     (d) Not applicable.

     (e) Not applicable.
