I haven't had the time nor patience to read through every post, and such if my suggestion has already been made, I apologise in advance.
I would suggest, in a situation like this, that one possible course of action is to tackle these pirates in the same way America did in Colombia with the drug lords. As these operations are business like and well organised, they are very similar to the drug cartels operating in Colombia. The use of organisations such as the now officially 'dismantled' ISA to gather a variety of intel such as humint and a variety of electronic forms of intelligence gathering to paint a picture of the layout of the hierarchy of the pirate's organisation. After said intel is gathered and consolidated, passing it on to Spec Ops teams would allow them to target weaker points in the hierarchy and slowly dismantle it person by person until it collapses. The co-operation between the intel services and the Ops teams is vital, but it obviously worked in Colombia, so why not try it with the pirate organisations. instead of just trying to protect the ships, why not eradicate the problem from its base. The use of satellite imagery and humint should provide enough information to start such a process, with attacks on known bases and ships while picking out and removing key figures in the structure of the organisation.
