Oceanic departures for my operator are approved for high speed climbs out of LA. Where EVA may have gone wrong here is that you have to be clear of the coast to accelerate past 250kts.
AFAIK, your operator cannot approve that unless they have a specific waiver. You have to be beyond 12 miles from the coast to accelerate above min clean speed if >250 KIAS/<10,000'. AIM 4-4-12.j:
j. Speed restrictions of 250 knots do not apply to U.S. registered aircraft operating beyond 12 nautical miles from the coastline within the U.S. Flight Information Region, in Class E airspace below 10,000 feet MSL.
If you think you have such approval, where/how is it written?
