Abstract: In a first aspect, there is a helicopter skid landing gear assembly including a front cross tube configured to interconnect two skid tubes; and a rear cross tube configured to interconnect two skid tubes; wherein at least one of the cross tubes comprises a monolithic metallic tube having a cross-section with a round exterior shape and an elliptical hollow portion therein. In a second aspect, there is a method for retrofitting a helicopter with a landing gear assembly; the method including providing a front cross tube and a rear cross tube, at least one of the front cross tube and the rear cross tube comprises a monolithic metallic tube having a cross-section with a substantially round exterior shape and an elliptical hollow portion therein; and connecting the front cross tube and rear cross tube to a fuselage.

Abstract: The invention relates to an upending system for an elongated tubular element like an offshore foundation pile or a turbine mast, the system comprising; a pile frame for supporting a elongated tubular element, the pile frame comprising a pile support member for engaging a pile wall in order to avoid movement of the elongated tubular element with respect to the pile frame, and a coupling section, a support structure for supporting the pile frame, wherein the coupling section is rotatably supported by the support structure to allow rotation of the pile frame with respect to the support structure, wherein the support structure and the coupling section of the pile frame are configured such that the pile frame is detachably coupled to the support structure.

Abstract: A cartridge of tubulars may be removably positioned with a carriage, and the carriage may move the cartridge transversely, vertically, and/or rotationally to roll tubulars on an adjacent tubular receiving member using only gravity from a selected tier of tubulars without human contact. A single trolley disposed with the tubular receiving member both pushes and pulls tubulars toward or away from the drilling deck.

Abstract: A telescoping, adjustable length tool basket, particularly suitable for offshore operations in the oil and gas industry. A center section has four elongated, tubular corner members, joined by bottom and side members. At least one, and preferably two, wing sections comprise elongated inner corner members that are slidably disposed within the outer corner members. The wing sections can be moved inwardly and outwardly from the center section to adjust the overall tool basket length to accommodate the tool length. When adjusted to the desired length, a lock pin is inserted through aligned holes in at least one pair of outer and inner corner members, to lock the tool basket at the desired length. Inner and outer bushings are disposed in the annulus between the inner and outer corner members. Preferably the bushings are of a polytetraflouroethylene (PTFE) material such as Teflon®.

Abstract: A transport device for transporting elongated substrates through a vacuum coating system comprises an essentially rectangular frame and two groups of holding elements, which are rotatably mounted on opposite sides of the frame in such a manner that any pair of opposite holding elements can be connected to both ends of a substrate. Furthermore, at least one retainer bar is provided that is operatively connected to a group of holding elements in such a manner that the holding elements of this group are moveable in order to increase or decrease by choice their distance from the holding elements of the other group. Also provided are a loading and unloading device for loading and unloading the transport device, and a method for loading and unloading the transport device.

Abstract: A pipe conveyor system which operates to assemble and disassemble a plurality of pipes.

Abstract: A device for transferring objects (100) from a printing machine chuck (2) to a support and distancing pin (51), the chuck (2) and the pin (51) being moved on two independent paths, at a point of which paths they are parallel to one another and at a predetermined reciprocal distance, the device comprising a carriage (40) which is mobile in a parallel direction to the chuck (2) and to the 5 pin (51), between a distant position from the chuck (2) and the pin (51) to a close position to the chuck (2) and the pin (51), means (46) for gripping and releasing the objects (100) being provided on the carriage (40), which means for gripping and releasing are mobile along a trajectory in a perpendicular plane to the carriage (40) in order to be placed alternatively in front of the 10 chuck (2) and the pin (51), the trajectory including at least a tract in which it is parallel to the path of the pins (51).

Abstract: A system for laying a pipeline from a floating vessel onto the ocean floor in relatively deep ocean water which provides an erector for raising new pipe sections to be added to a pipeline which is depending from the system, the pipe sections being raised into accurate alignment with the mast of the system although the mast is free to be gimbaled in any direction within two degrees of angular freedom.
