Narrative:
We were assigned; and wrote down dosel departure [and] cleared to 5;000 feet. The other international relief officer also copied the same clearance. The dosel and the bryson departure have a similar turn and it wasn't until passing albak waypoint that the controller asked what departure we were on and issued a heading of 270. Communication at times can be an issue; pre departure clearance is an excellent way to close that weak link.

Title: Air carrier flight Crew reported a track deviation due to confusion with the departure clearance delivery format.
Narrative: We were assigned; and wrote down Dosel departure [and] cleared to 5;000 feet. The other IRO also copied the same clearance. The Dosel and the Bryson departure have a similar turn and it wasn't until passing ALBAK waypoint that the controller asked what departure we were on and issued a heading of 270. Communication at times can be an issue; PDC is an excellent way to close that weak link.
