A sealing element for pipes comprises a body made up of a section of stem that has a circular plant head region at one end that acts as a grip area. The stem section includes in a downward direction from the head region a plurality of parallel positioning regions with a substantially discoidal shape, having a primary positioning region that has a larger diameter than remaining secondary positioning regions. The primary positioning region has two sections devoid of material diametrically opposed to each other, so as to define two opposite fins capable of bending. A positioning region adjacent to the primary positioning region in a direction to head region has two sections devoid of material which are offset by 90 degrees with respect to the positioning of the two sections devoid of material of the region of primary positioning.

An apparatus for sealing a tubular section is provided. The apparatus may include a retainer and a dart. The retainer may include an annular body having a tapered outer surface and a slip having a left-hand thread profile defined in the slip. The slip may expand along the tapered outer surface of the annular body to hold the retainer in position within the tubular section. The dart may include a sealing element and a vented cap. The sealing element may include a body, a plurality of fins, and an engagement member that engages with a cavity of the vented cap. The cap may contact the annular body of the retainer. The sealing element may compress against the cap, sealing the tubular section.

A system and method for laying an underwater pipeline is provided. The present invention includes a plurality of pipe support rings connected together by tension cables. The tension cables are secured to a S or J laying ship by a winch. The plurality of pipe support rings form a pipe channel sized to guide the underwater pipeline. The present invention further includes a sea water pipe having a distal portion and a proximal end. The proximal end is fluidly connected with a pump on board the ship. The distal end includes a plurality of nozzles. The sea water pipe is disposed underneath the plurality of pipe support rings. The underwater pipeline is fed through the plurality of pipe support rings while the nozzles form a trench on a sea bed.

The present disclosure relates to an insert and system of installing the same. The insert includes a tapered core and a cylinder. The core releasably secures to an installation device which includes a depth stop or a depth control to control the installation depth of the insert. The insert may be provided in a tray that allows for easier handling of the inserts and installation thereof in installation holes, for example in a hydraulic manifold. In some cases, the core includes a threaded hole to releasably secure the insert to the installation device, thus allowing the installation device to pull the core into the cylinder. The core and cylinder may be made of metallic materials such as steels, steel alloys and others. In some cases the insert can withstand blow out pressures of 40,000 psi or higher.
