PCT No. PCT/GB86/00440 Sec. 371 Date May 4, 1987 Sec. 102(e) Date May 4, 1987 PCT Filed Jul. 23, 1986 PCT Pub. No. WO87/00501 PCT Pub. Date Jan. 29, 1987.View port for an underwater vehicle, e.g. for a remotely operated vehicle (ROV) usable for underwater inspection, and provides a view port (2) which can form a component of a pressure hull of an underwater vehicle, and which can be sandwiched between hull portions (4) to provide a transparent section girdling the hull. Preferably, the view port can form a component of a substantially spherical pressure hull, the view port being sandwiched between two similar part-spherical hull portions. The invention further provides an underwater vehicle having a view port which forms a component of a pressure hull and which provides a transparent section girdling the hull. A camera (10) may be pivotally mounted in the hull so as to allow rotation of the camera to view through the port. A light source may be provided in the hull and arranged so as to allow light from the light source to be shone out through the view port. The view port may be an integral ring of transparent material and the view port may provide a field of view over a full 360 DEG . |
