Offshore Access Solutions

To achieve that experience, Ampelmann Operations’ employees perform their tasks based on the company’s four core values: safety, professional excellence, team spirit and technological excellence. All personnel is properly trained. All operations are planned and detailed before execution. We use Hazid meetings to discuss the operation with the Ampelmann system within our client’s larger project to ensure all interfaces are understood and documented. In the design of our systems FMEA studies are executed to ensure any single failure of a critical component is covered by back-up components, proper operational protocol is followed and checked against common sense. Ampelmann systems are certified under the Code for Lifting Appliances in a Marine Environment. Furthermore, Ampelmann also involves automotive experts in software fool-proofing and we are in continuous discussions with national HSE departments and clients’ HSE experts to continue to improve safe operations with our expanding fleet and services offered.
