Abstract: Method and system for handling riser pipe on an offshore vessel, comprising taking the pipe from the stack of riser pipes using two trolleys placed on opposite sides of the stack, each trolly having means to engage with a respective end of the pipe, and loading the pipe into the cradle of a lifting device for lifting the riser pipe from the storage zone onto the deck of the vessel.

Abstract: System and method for handling riser pipes on an offshore vessel having two reciprocally spaced trolleys provided with engagement means able to engage with respective ends of the riser pipe.

Abstract: Automatic hooking device with controlled releasing operation is mounted to a ship or other transportation device with a hooking member having an engaging member operated by ascending movement of a block and fixed to a support structure on lifting blocks, the hooking device is a system of moveable levers reciprocally interconnected by pins, the levers move the hooking device between two end positions to engage or release with the block depending on if the hooking device is in the engaging or releasing position, where a control device operates the hooking device and levers to move the hooking device between the engaging or releasing position to secure or release the block.
