  • Patent number: 10288208
    Abstract: A corrosion protected metal pipe for installation in an offshore structure or for producing a pipeline laid in water is provided. The metal pipe has an at least two-layer covering on the pipe with a lower layer facing the pipe and an upper layer on a side of the lower layer not facing the pipe is provided. The layers are formed such that the lower layer is electrically conductive and the upper layer is electrically insulating, the lower layer is optically contrasting to the upper layer, or the lower layer is electrically conducting and optically contrasting to the upper layer and the upper layer is electrically insulating. Thus, in the event of damage to the layer or layers lying above, a visual or electrical signal can be detected. Damage to the corrosion protection covering can therefore be detected easily and, if appropriate, reported by remote monitoring.

  • Patent number: 9657878
    Abstract: A plug connection includes a first plug connector, a second plug connector which can be inserted in the first plug connector, and a detent spring fastened to the first plug connector. The detent spring engages in a groove of the second plug connector when a second plug connector is inserted. The detent spring can be moved from a locked position into an unlocked position. In the locked position the detent spring is prevented from effecting a movement radially outwards into an unlocked position. In the unlocked position the movement of the detent spring radially outwards is unblocked. A release device which can be selectively activated is provided on the first plug connector. The activated release device holds the detent spring in the unlocked position.
