Narrative:

On departure from hkg runway 7R; ocean 2A SID. On switch to departure control; I asked for high speed. The controller said unable and immediately cleared the company flight just in front of us to go direct to ocean. I thought the clearance was for us and read back direct to ocean. The controller was difficult to understand with a thick accent. I selected direct ocean in the FMC. Then the controller read the clearance again and I confirmed. The pilot flying (PF) was hand flying and asked for speed intervene 220 and flaps 10. I then executed the direct ocean in the FMC. The relief pilot then inquired about the clearance so I confirmed with controller. The controller told us to stay on the SID spelling out each letter. I didn't understand this phraseology. The second time I understood he meant for us to stay on the SID. The SID was now deleted from the FMC so I asked for direct to ocean. Controller said unable and to climb to 9;000. I asked for direct to td. Controller said unable. I asked for a heading to rejoin the SID. Controller said unable. I then attempted to reinstall the SID and give the PF a heading. PF flying flew 130 degree heading. PF was still hand flying so I asked him to engage the autopilot. Controller gave us climb 8;000. As I was reinstalling the SID; controller gave us direct to td. We then proceeded direct td and leveled at 8000. Fatigue is always a factor when things go wrong. Multiple events led up to this issue.

Title: On the OCEAN departure from HKG; the Captain executed a clearance for another aircraft to go direct OCEAN. This resulted in an improper flight guidance which created confusion and led to track and altitude deviations.
