Marsh, insurance broker and risk adviser, and REDfour (MSS) Ltd, a maritime security firm, announced they are working together to help shipowners address potential exposures associated with piracy attacks in the Gulf of Aden. Shipowners working with REDfour for security services and with Marsh for kidnap and ransom (K&R) insurance coverage may qualify for significant reduction in their overall K&R insurance costs. In addition, Marsh and REDfour have agreed that clients binding with certain underwriters will be provided services from REDfour at a reduced cost.
