Shipping company Liberty One, already subscribed to INTERSCHALT's maintenance software package, decided to establish a full maintenance contract covering all navigation and communications systems on board including the VDR. After six months, say INTERSCHALT, the Bremen-based shipping company is seeing positive results. As part of its Shore-based Maintenance (SBM) contract INTERSCHALT provides all inspection and maintenance work as well as parts and parts procurement at an annually agreed fixed price.
