摘要： Flexible riser hang-off for rigid risers deployed offshore is provided and called a spoolflex hang-off. The spoolflex hang-off utilizes combined torsional and bending flexibilities of a rigid tubular jumper deployed between a top of the riser and a floater piping. The rigid jumper transports fluids, contains the fluid pressure and accommodates angular deflections of the riser. The riser top is suspended from a pivoting arrangement that transfers the riser tension to the floater structure. The rigid jumper can be made of titanium or of other metallic or nonmetallic materials.The flexible riser hang-off provided has rotational stiffness independent on riser tension. Low static and fatigue bending loads on the riser and on the floater structure result. The hang-off allows large riser deflection angles.

摘要： A subsea riser support buoy is disclosed having a riser support member and a jumper support member that extend generally parallel to each other and that define a lengthwise direction extending between them across the buoy. Pontoons extend lengthwise beyond the riser support member and the jumper support member to provide attachment points for connecting tethers to the buoy. In this way, the attachment points are spaced more widely than lengthwise extremities of the riser support member and the jumper support member, beneficially altering the dynamic behavior of the buoy and especially its pitch characteristics.

摘要： A system and method are provided for detecting fluid invasion of an annular space in a pipe structure. The system includes a thermal element and a temperature sensing element placed in the vicinity of each other in the annular space of the pipe structure. A thermal signal is generated by the thermal element. The temperature sensing element is connected to a monitor that monitors and processes the thermal signal. As the thermal signal changes when conducted through different types of fluids, the invasion of an annular space by seawater that normally contains oil or gas may be reliably detected.

摘要： The invention relates to an offshore system for transferring fluid at least partly below sea surface. The offshore system comprises a flexible transporting unit and a first movable structure fix-point with a nominal position and a second structure fix-point arranged at a distance to seabed and at a lower position relative to the sea surface than the first structure fix-point. The flexible transporting unit is fixed to respectively the first structure fix-point and the second structure fix-point to provide a catenary liftable length section of the flexible transporting unit extending between the first structure fix-point and the second structure fix-point, wherein the catenary liftable length section has a touch down point at seabed at nominal position and where the distance to the second structure fix-point can be increased sufficiently to lift the catenary liftable length section from the seabed to form a catenary.

The pipe comprises in order from inside to outside: an interior lining; a wound tape; and at least one reinforcement layer. The wound tape contains a first exterior layer of a plastics molding composition that is not electrically conductive; an intermediate layer of an electrically conductive plastics molding composition; and a second exterior layer of a plastics molding composition that is not electrically conductive. A volume resistivity to IEC 60093 of the intermediate layer is in the range from 10−3 to 1010 Ωm, and the intermediate layer comprises at least two metallic conductors embedded into the plastic molding composition along an entire length of the tape in such a way that, the two conductors do not touch one another.
