Caterpillar Inc, an American company with divisions worldwide, designs and builds heavy machinery for road and waterway construction and mining. It also produces generator sets and other equipment powered by diesel engines and gas turbines. The company wants assurance about the quality of its products and components, even when stored in ports or during transport at sea. For this purpose, the company wanted a number of engine blocks transported around the world to be tested in their packaging under extreme conditions. As such, it could find out whether the packaging material adequately protects the products during sea transport and storage.
