The Ocean Specialists, Inc. (OSI) patented Portable Dynamic Riser (PDR) system provides a step change in the communications capability of any mobile asset that is working on existing subsea oil & gas fields. No longer are these valuable assets and the work that they are employed to perform limited to high cost, low bandwidth satellite, or microwave communication. The PDR provides the capability of direct fiber-optic communication at data rates up to full gigabit Ethernet with multiple gigE channels being available on a single fiber.
The PDR is a classically simple deployment system, using only proven deep water components, that provides a direct fiber-optic connection between a Mobile Offshore Drilling Unit (MODU) or or other facility, and an existing wet-mate connection point, typically an Umbilical Termination Assembly (UTA) that has a spare wet-mate fiber-optic connector available. The PDR system provides the primary communication path between the mobile facility and the production platform, which provides the fiber connection to shore. The now secondary satellite or microwave system then provides backup communications in the case of failure in the fiber network. With direct fiber communication, latency problems are removed, and decisions on data priority are redundant.
The self contained PDR system's small footprint and portability ensure that once one vessel has completed its in-field tasks, the system can be quickly de-mobilized, stored and as quickly and easily mobilized onto the next vessel that is working in the field.
