Framework for evaluating customer value and the feasibility of servicing architectures for on-orbit satellite servicing
… method that is examined is on-orbit satellite servicing. On a basic level, on-orbit satellite servicing is the process of providing services to a satellite in orbit, such as: relocation, refueling, repairs, or upgrades. The purpose of this thesis is to describe and support a framework for …

On-orbit servicing for satellite upgrades
Except for manned servicing operations using the Shuttle, there is no maintenance infrastructure for space systems. The traditional approach is to build in reliability and to replace the system in case of obsolescence or failure. Space systems therefore offer a limited degree of flexibility to …

Innovative hull design for servicing offshore wind turbines
Accessing turbines for maintenance is a key operational issue for an offshore wind farm. Currently there is a 1.5m significant wave height (Hs) limit for the standard “step over” method of transferring personnel to an offshore wind turbine, though this varies with, vessel type, wave period and …
