Abstract: A reinforced composite laminate for an aircraft and a method of manufacture thereof. The laminate includes a set of stacked plies of pre-preg material laid up forming an XY plane, wherein the laminate further includes a plurality of elongated carbon pins including a round section with a diameter smaller than 0.5 mm. The pins are nailed through the stacked plies following the Z direction to withstand the out-of-plane loads.

Abstract: A rear pressure bulkhead comprising a dome shaped structure, and a set of built-in extension components (“petals”) homogeneously distributed along the periphery of the dome-shaped structure. This results in the dome-shaped structure being secured to a frame of the aircraft, while the extension components are secured to longitudinal structures of the aircraft. An aircraft rear fuselage is provided including such a rear pressure bulkhead so that the available cabin space, i.e., pressurized space, is extended without enlarging the fuselage.

Abstract: A method for disposing of an offshore platform jacket comprises suspending the jacket in one piece under a tow vessel, towing it to the disposal site and safely and quickly releasing the jacket at the disposal site. Once the jacket foundation piles have been severed, the first end of the jacket is lifted using a derrick barge crane or winch connected to a first lift rigging device until the first lift rigging device engages with a first release device. The second end is lifted in a similar manner with a second lift rigging device and a second release device until the jacket is suspended substantially beneath the tow vessel. The lift rigging device include a spreader bar having at least one skid shoe attached thereto, at least two padeyes attached at opposite ends of the spreader bar, a lift sling attached to the padeyes and at least two jacket support slings. Each release device is attached to the tow vessel and includes at least one rocker beam having a connector.
