ISES is essentially a non-profit enterprise that exists to co-ordinate and market the international activities of its member companies.The objective of ISES is to unite an independent, high quality worldwide network of members to provide electrical, mechanical, electronic and specialised services to the marine industry.

Member companies benefit from being part of a global network which enables them to extend their services worldwide and share technical knowledge and co-operation with other members. The ISES Marine Service Guide is produced annually and mailed to over 5,000 ship owners and managers, thus raising members’ profiles by listing their full details, locations and capabilities to potential customers.
