An amusement device, in particular a roller coaster, for providing a sense of excitement to one or more passengers using the amusement device. The amusement device has an elongated track along which one or more amusement device seat assemblies adapted to carry the one or more passengers are moveable. Each seat assembly has a seat with a seating surface and a back support with a back support surface. The seat assembly further includes a bar construction attached to a pivot mechanism. This bar construction has a hip bar and one or more pivot arms integral with the hip bar, which bar construction is pivotable about the pivot axis from a raised position in which the hip bar is raised from the seating surface to allow a passenger to sit down in the amusement device seat assembly, to a lowered position. The bar construction is such that no part of the bar construction takes away the view of the person and limits the movements of the arms of the person, allowing the passenger to experience a great sense of freedom.The seat assembly further includes a belt construction with two shoulder straps and an adjustable length mechanism associated with each shoulder strap to allow for adaptation of the length of the shoulder straps to the size of the passenger in the lowered position of the bar construction such that the shoulder straps are in physical contact with the shoulders and upper part of the body of a passenger seated in the amusement device seat assembly so as to increase the sense of safety of the passenger.

The invention relates to marine pipe laying. For laying of an offshore pipeline, a system is used having a hoisting device. The hoisting device comprises a tower with a tower top side provided with cable pulleys. Furthermore the hoisting device has a traveling block which is displaceably attached to the tower. The traveling block comprises a first block and a second block, both provided with cable pulleys. The first block is provided with a clamp for holding a pipe section to be connected to the pipeline as well as for lowering the pipeline after the pipe section is connected to the pipeline. The hoisting device has a hoisting cable and a winch, the hoisting cable being guided over the cable pulleys on both the tower top side and the traveling block. The traveling block is moveable with respect to the tower by operation of the hoisting winch. The first block and the second block are adapted to be releasably coupled, in which coupled state they can travel along the tower as a unit and are able to support the weight of the pipeline. The second block can be locked to the tower, such that the first block can travel along the tower while the second block remains stationary with respect to the tower.

The embodied mobile cranes have a travelling base structure that allows for travel of the crane over a surface. The cranes have a revolving superstructure mounted on the base structure and a boom and a backmast. The boom and backmast are each hinged about an associated pivot axis to horizontal the superstructure. The crane has a main load hoisting manner associated with the boom for hoisting a load. A superstructure ballast is supported on the superstructure. The cranes have a superlift ballast and associated connection manners to connect the superlift ballast to the backmast while the superlift ballast is resting on the surface and/or suspended from the backmast above the surface. The travelling base structure is provided with superlift ballast support to support the superlift ballast on the base structure so that the superlift ballast is movable along with the mobile crane while being supported by the base structure.

A method to construct and transport a modular drilling rig comprising drilling equipment in the form of a transfigurable container begins by transporting transfigurable shipping containers comprising drilling equipment to a drilling location. The method continues by unfolding the transfigurable shipping containers and the drilling equipment at the drilling location, and connecting two or more of the unfolded transfigurable shipping containers to form operable drilling equipment. The operable drilling equipment is erected into a drilling rig, wherein the operable drilling equipment comprises a drill floor, a mast substructure; a mast; a control cabin, a drawworks; a blow out preventer; a choke and kill manifold; a blow out preventer (BOP) control unit (38), not shown. The method ends by connecting piping and cabling for communication and power cabling to the erected operable drilling equipment and, then, operating the drilling rig.

A modular transfigurable drilling rig comprises one or more transfigurable containers with drilling equipment to form an operational drilling rig. The transfigurable containers include a first and second load bearing support and a load bearing bottom disposed between the first and second load bearing supports, thereby forming a space. The container includes drilling equipment rotatably attached to the load bearing supports or the load bearing bottom. The drilling equipment is disposed within the space. The drilling rig further includes one or more connectors adapted to engage at least two transfigurable containers together. The drilling rig further includes piping adapted to connect the drilling equipment together, cabling adapted to provide communication between the drilling equipment, and a power source connected to the drilling equipment, wherein the power source is adapted to provide power to the drilling equipment.
