Caterpillar has formed a new Marine Business Unit within the Engine Products Division. The reorganization is designed to strengthen the company's focus on marine customer needs and streamlines communication and response in all aspects of Caterpillar's global marine engine business. Leading the new organization is Jan Arnold, a veteran marketing and sales manager with 21 years experience working not only for Caterpillar, Inc. In addition to steering a team of special business managers focused on specific marine market sub-segments, Arnold will coordinate the efforts of five managers. Bill Heimann, a 27-year Caterpillar engineer with extensive experience in product design, applications and product support, will be marine product group manager.
