Ferry schedule extended to suit late events at AsiaWorld?

Hello, I would like to ask if the ferry line "Hong Kong Airport - Shekou Port" can have extra late boats on weekdays, when there is a late event (e.g. concert) at the AsiaWorld Expo at the Airport? The event that I want to visit ends approximately at 23:30 and I am wondering how to get back to Shenzhen after that? Thanks for your answer in advance!
