I worked through ATIS for Intresco on coasters. The vessels were worn out, the salary was low, and payments were delayed by a month. It may be suitable for starting out, but not beyond that.
I worked through ATIS for Intresco. The company recruits both officers and ratings, including people starting in their positions. Contracts were 3 months plus 1 or 4 months with a possible extension of around 2 months. My salary was delayed by two and a half weeks once, but it was eventually paid in full with bonuses; supplies were delivered, and internet was available on the vessels. A crewing commission may be charged, and if you do not submit an extension request, the company may find a replacement before you decide whether to extend.
