Richard Turner, an insurance professional for 35 years, will take the helm at the International Union of Marine Insurance (IUMI) in September.
He will replace Dieter Berg, who is stepping down after serving a four-year term as president.
Turner has spent his entire career at London-based RSA Insurance Group, where he was a hull underwriter from 1989 to 2001.
He went on to run RSA's London market marine operation from 2002 to 2009 before becoming Europe Marine leader.
