[2] On Ocean's second voyage, Patton was again her captain and he left The Downs on 13 October 1802 for the Cape of Good Hope, Madras, Bombay and China.

After the resumption of war with France in 1803, Patton posthumously received a new letter of marque dated 1 July 1803 for the same vessel, with a crew of 140 men and 36 guns.

[3] Patton died at Bombay in June 1803; Ocean's first lieutenant, John Christian Lochner, became captain and it was he that commanded her at the battle of Pulo Aura.

On 14 February 1804, the China Fleet, under the command of Commodore Nathaniel Dance, intimidated, drove off and chased a powerful French naval squadron at Pulo Aura.

Dance's aggressive tactics persuaded Contre-Admiral Charles-Alexandre Durand Linois to retire after only a brief exchange of fire.

Lloyd's Patriotic Fund and other national and mercantile institutions made a series of awards of ceremonial swords, silver plate, and monetary gifts to individual officers.

On 7 August Ocean was in company with the East Indiamen Henry Addington, Dorsetshire, and Cumberland in a convoy escorted by naval vessels under the command of Sir Thomas Troubridge.

[5] The British exchanged fire with three French warships that included Belle Poule and Marengo,[5] which did not press the attack.

On the return leg Ocean was "off Chumpee" (Chuenpee) in the Bocca Tigris, the estuary of the Pearl River, on 26 February 1806.
