As said above SA 330J is an excellent work horse. If your contract is to fly above the seas, somewhere in the pacific or Persic gulf, keep in mind that you will not be harassed by flying hours. But you will provide ice cream, eggs, brooms, pony etc... to sailorman really happy to hear of you.
As soon as you are type rated on SA 330, conversion to 332 L1 is peanuts. L2is a different bird.
Cheers
