The crew are rarely trained and equip to respond to an armed attack. If they have anyone to defend the ship, at most it's a handful of mercenaries hired for the high risk part of the trip.

For instance in the last (Somali) attack before this, a Maltese flagged tanker was boarded, and a Spanish warship arrived the next day and retook the ship.
Once the ship is captured, it's held for ransom, the insurance company gets their negotiators to minimize the price, they eventually pay the negotiated ransom, and insurance rates go up.
If you're expecting someone to prevent piracy, you need to first run the financial cost/benefit analysis. How much would need to be spent on a military operation, and what's the return that would be seen from the country sending their military to rescue a private ship registered to a foreign country, staffed by foreign crew, with cargo destined for a foreign country?
UNCLOS permits any country to intervene in case of piracy. Because piracy attacks the public good of assured, consistent, low cost maritime transit and commerce (which the entire developed world is addicted to), and successful piracy begets piracy, there are a lot of countries with a lot of resources deeply interested with intervening.
And Operation Atalanta by the EU.
That said, when mercenaries are defending a ship, it's often trying to stop a small runaway boat loaded with explosives. It's a very small moving target they have to hit with little time. Meanwhile the small boat just needs to be pointed somewhere in the direction of the oil tanker.
