The global shipping industry plays an oft-unseen and yet crucial part of maintaining our lives in the 21st century. In fact without the shipping industry our lives would be unrecognisable from the ones we lead today. If the ships themselves are unseen, then the men and women who operate these vessels are even more unseen. These seafarers have health requirements the same as any other person, and due to the unique set of hazards they face, providing for their health needs can be more complex than for people in different walks of life. Yet ensuring a healthy workforce is essential for the effective management of any vessel, and indeed any shipping line. This is where MMS can come into play.
