Abstract: The invention relates to the field of special purpose robotic systems to conduct external functions such as cleaning, monitoring and inspection of structures such as tubular assets in a splash zone. The splash zone is defined as the section of a marine structure that is periodically in and out of water due to the action of waves or tides, usually falling within (+)10m to (?)20m water depth. In embodiments, splash zone inspection robot system 1 comprises station 300, submersible saddle 350, submersible robot 400, and subsea robot controller 308. A predetermined set of controllable clamps selectively secure submersible robot 400 to submersible saddle 350 or structure 2 and allow incremental traversal along submersible saddle 350 or structure 2.

Abstract: Seal assembly 100, useful for repairing an uncontrolled surface such as pipeline 110, comprises seal 102 which is subjected to pressure and temperature and remains operable under, e.g., subsea conditions. Seal assembly 100 is capable of sealing pipelines of diameters up to 48 inches. Seal assembly 100 is actuated/energized by axially compressing/loading seal assembly 100 between one or more controlled surfaces and an uncontrolled surface and can be used for repairing and providing sealing in flowline or pipelines of either subsea or other petrochemical industries where the pipelines. Spool assembly 700 comprising seal assembly 100 may be used to repair a damaged pipeline section after the damaged section is removed to provide a sealed replacement fluid path for the pipeline.
