Offshore Transfer Devices Ltd

Soon to launch the TDD (Tube Docking Device) access system. A patented concept funded and supported by the OWA Carbon Trust which is a leading international collaborative R&D program with the Carbon Trust and nine leading offshore wind developers. The TDD will deliver the desired performance offering a safe, reliable, measurable, economic and simple solution to the business of transferring personnel and equipment offshore. This will afford greater access and workable weather windows, resulting in increased productivity and reduced losses caused by failed transfers which prove difficult with conventional access fender methods in adverse weather conditions. The TDD is a light, compact device used to effectively stabilize, pin and grip the transfer position to a structure offshore. It will also cushion and protect both device, vessel and structure in greater wave height in challenging adverse weather conditions.The motivation for the device throughout the process has been to make it fail safe, ensuring that mechanical entanglement to the offshore structure impossible. This is achieved by making the amount of grip applied to a structure relative to propulsion force applied and two key factors considered thorough our model designs and testings were to keep the device as simple and as light weight as possible.The TDD can be made to fit any size vessel whether to aid a daughter craft capabilities with an ultra-light weight compact device weighing at just 150kg or full size 1250kg device for the larger 26m+ CTV/WFSVs. For the larger vessels minimizing pushing force to maintain grip and exclude the possibility of impact loads whilst docking on to the wind farm structures in adverse weather conditions is becoming ever more imperative. There are several ways to apply the TDD access system, such as vessel to offshore wind farm structure, Oil & Gas platforms, vessel to vessel transfers, aiding compensated gantry applications with mother ships.
