An apparatus for close visual inspection of subsea pipelines comprises a housing with a chamber that has an open side. The open side is adapted to be placed in sealing engagement against the pipeline. The chamber is flooded with clear water to improve the visual view. It is also described an apparatus for identification of a plume exiting from a leak The apparatus comprises a housing defining a chamber with a water permeable side that is adapted to face downward during use, and thereby being exposed to the exiting substance. A gas pressurizing device for creates a gas/water interface within the housing. An imaging device arranged above the water surface is adapted to image the water surface and detect id the water surface is being disturbed by the plume.
