Can I get a transfer from a cruise-ship to beijing airport?

Hey, I guess you mean Kai Tak Cruise Terminal, am I right?
If I understand you correctly, I think you want to take cruise ship to HK airport, and take flight there to Beijing, yes?
You can take Green minibus No. 86 from the cruise terminal to Kowloon Bay MTR Station. After arrival, transfer to bus A22 at Telford Gardens, Kwun Tong Road to HKIA. Then fly to Beijing.
