I did this as Prussia and here is how to do it.

First, sign a trade treaty with GB. Create the schichau company. Rush streamers tech, put highest possible subsidies on clippers and streamers. GB shipyards are no longe profitable and start downsizing. Shipyards are needed to produce supply ships. No shipyards no supplyships. GB couldn't help its subjects in any war. This probably works on any global empire.

Have fun.
