So can someone tell me about a captain's job on Kwajalein in the Marshall Islands

Would like to hear about a pay scale, straight out no comparison. For a 1600 ton master oceans DP no limitations, etc etc. Also a scale for a registered nurse, ten years experience, mostly in ICU. Were thinking about going as a couple. Were just interested in what kind of job opportunity’s there are, if it would be worth the tax free benefit of the year long stay. Thanks and I do appreciate your time to respond.
