Bionic high holding power anchor
The present invention discloses a bionic high holding power anchor, which includes an anchor rod, a suspension clasp coupled with one end of the anchor rod and an anchor fluke hinged with the other end of the anchor rod, wherein a plurality of fluke heads arranged at equal intervals are extended from a front end of the anchor fluke, fin-like streamlined balance wings are arranged at two sides of the anchor fluke; the fluke head is in a shape of triangle-like taper containing a plane side wall and two curved side walls, the plane side wall is an isosceles triangle, the two curved side walls are smooth curved surfaces, and the two smooth curved surfaces are symmetrical around a normal plane of the plane side wall. According to the bionic high holding power anchor of the present invention, the balance wings are arranged at the two sides of the anchor fluke, a body is avoided from being turned completely and the anchor reaches to a soil layer at a correct working angle during a process that the anchor is thrown into water; and a longitudinal dimension of the anchor is increased, so that an anti-turning property of the anchor in the soil layer is improved significantly, and a risk of anchor dragging is reduced.
PROCESS OF ANCHORING A FLOATING PLATFORM ON A ROCKY SEABED
A process of anchoring a floating platform on a rocky seabed, comprising the following steps: providing at least one trench portion in the seabed, the trench portion extending along a line, installing an anchor structure in the trench portion, the anchor structure comprising a core extending along the line, steel plates welded to the core and extending from the core radially with respect to the line, and at least a first grout line, injecting grout in said first grout line in order to fill the trench portion with grout, the plates being at least partly surrounded by the injected grout, and after curing of the injected grout, connecting a connecting point of the core (to the platform using a mooring chain.
Fluked Burying Devices
A fluked burying device (1, 1A), for augmenting the burying and holding capability of a drag embedment marine anchor and chain cable system while being fixedly located thereon, comprises a fluke member (8) inclinedly attached to a body member (7) including pockets (12A, 12B, 12C) for accommodating links (16, 17) of a chain cable (4) passing there-through in a defined attitude such that axial and transverse loading is impressed in the chain cable (4) via separate links (17A, 17C) to maintain bending stresses therein similar to that occurring in a 5-pocket wildcat of a chain windlass and such that emergent links (16A, 16B) have sufficient articulation in service while embedded to permit the chain cable (4) to perform the function of and eliminate need for heavy expensive shackles. The fluked burying device (1, 1A) enables soil loading from a plurality thereof to be distributed along a length of chain cable (4) and is preferably provided with a body member (7) less wide than the effective footing width of a chain cable (4) and preferably split about a plane of symmetry (5) in two halves (2, 3) for ease of transport within container gauge.
Conduit displacement mitigation apparatus including springs, methods and systems for use with subsea conduits
Disclosed are apparatus, systems and methods for reducing displacement of a subsea conduit such as offshore hydrocarbon production pipeline, also referred to as pipeline walking or buckling, thus reducing the need for expensive pipeline anchoring or other mitigation solutions. A movement resistor adapted to be installed on a subsea conduit is provided having an inner portion adapted to receive and securely attach to a subsea conduit and at least one resistor portion adapted to resist induced forces. The at least one resistor portion includes a spring element therein. At least one movement resistor can be installed along the length of a subsea conduit.
Tension foundation for holding a buoyant object
A tension foundation is provided for holding a buoyant object in flowing water via a tether. The tension foundation may include a spine component, rotation members rotatable about the spine component, slats, and additional features. The rotation members can include multiple types with distinct dimension ratios, which may be arranged in an alternating pattern. During operation, the tension foundation advantageously provides increased contacting edges to grip an uneven surface, such as a rocky lakebed or river bottom.
NAUTICAL ANCHOR
Nautical anchor comprising three flat pieces, consisting of a penetration nail, a positioning clamp and a supporting arm, which have a configuration that allows, quickly, easily, and without the need for the use of tools for it, the mutual coupling of the same, being firmly joined and arranged symmetrically with respect to a central vertical longitudinal plane and facing each other, in their working position, so that the nail and the arm are completely perpendicular to each other, the nail being located in a horizontal plane and the arm in a longitudinal vertical plane, while the clamp is located in an inclined vertical plane, facing transversely to the arm and forming an angle greater than 90 with respect to the nail.
