Operating on both land and water, ship repairers and marine equipment installers tackle a variety of tasks from general maintenance and repair, to upgrading electrical systems, to installing state-of-the-art navigational systems. Along with these tasks comes a wide array of maritime risk exposures, both large and small, for which the business owner needs to be adequately protected. The tasks of an electrician or welder are challenging enough on their own, but try to do this work on a vessel at sea or in a shipyard, and the technician will find that the hazard level rises dramatically – from making sure that all facets of the systems work together as they should, to the increased fire risk hot welding presents to the safety of the vessel.
