Who are we


Established in 1994, INTRAMAR’s initial success was founded on providing insurance cover and services suited to the many activities and safety regimes of oil and gas companies and maritime agencies.  By adapting and evolving these policies, its service and client portfolio has expanded to meet the operational and legislative demands of the offshore wind industry, for which INTRAMAR has provided expert cover since 2006. Large enough to secure premium value, whilst still providing a personalised service to its customers, INTRAMAR’s approach wins the support and endorsement of many long-term customers.
