Zusammenfassung:	An offshore hydrocarbon pressure control apparatus (20) comprises: a first subsea pipeline (26) configured to receive a first hydrocarbon flow; a second 5 subsea pipeline (28) configured to receive a second, different hydrocarbon flow; a turboexpander (22) configured to expand the first hydrocarbon flow; and a compressor (24) driven by the turboexpander and configured to compress the second hydrocarbon flow, wherein both the turboexpander (22) and the compressor (24) are located either subsea or on an offshore platform. Un appareil de régulation de la pression d'hydrocarbures en mer (20) comprend : une première conduite sous-marine (26) conçue pour recevoir un premier flux d'hydrocarbures ; une seconde conduite sous-marine (28) conçue pour recevoir un second flux d'hydrocarbures différent ; un turbodétendeur (22) conçu pour dilater le premier flux d'hydrocarbures ; et un compresseur (24) entraîné par le turbodétendeur et conçu pour comprimer le second flux d'hydrocarbures, le turbodétendeur (22) et le compresseur (24) étant situés soit sous la mer soit sur une plateforme en mer.
