Definitions
- the present invention relates to a fairing for mounting upon a cylindrical underwater member such as a marine riser.
- cylindrical member is exposed to water flow and must be protected from the effects thereof.
- VIV vortex induced vibration
- GB 1193750 describes a fairing device for a cable towed behind a ship.
- a "D" shaped channel to receive a cable 7 is formed along most of the length of the fairing between a flat
- US 4078605 depicts a fairing of teardrop shape having end walls with through-going openings to receive a riser. These openings are set well backward of the fairing's leading edge.
- US 4398487 (Ortloff) concerns a fairing which defines an internal channel to receive a riser and has a relatively elaborate spring-loaded bearing arrangement through which it engages with the riser.
- the fairing disclosed in US 6067922 is not a teardrop shape, but has a
- US 4171674 (Hale) is another document concerned with a fairing formed from two halves for assembly around the riser.
- GB 2334733 (Reading and Bates Development Co) discloses a fairing whose leading edge is

- the fairing body and are separated from each other along the length of the fairing body, the
- each collar is interposed between the fairing body and the cylindrical
- Each collar is preferably shaped to form a respective bearing ring for receiving the cylindrical
- Each bearing ring preferably has a substantially circular interior surface.
- An end portion of the collar may be initially free to allow the bearing ring to be opened out
- the collar comprises two bifurcated portions, one limb of each extending between the cylindrical member and the fairing body to provide clearance
- the front of the fairing body may be shaped to complement the cylindrical member, its

- the collar comprises a plastics material with an
- the collar comprises self lubricating material.
- the collar preferably comprises a plastics material with an admixture of an anti-fouling agent.
- fairing body and the collar are formed by separate plastics mouldings.
- the fairing body is preferably formed as a hollow plastics moulding whose interior
- the fairing upon a cylindrical member for underwater deployment, the fairing comprising a substantially
- wedge shaped fairing body which tapers from a front face of the body to its trailing edge
- At least one collar coupled to the fairing body and arranged to receive the cylindrical member and to mount the fairing upon the cylindrical member with the fairing body's front face
- Figure 1 is a perspective illustration of an assembly comprising a first fairing embodying the
- Figure 2 is a side elevation of the same assembly;
- Figure 3 is a section through the assembly at station A- A;
- Figure 4 is a section through the assembly at station B-B;
- Figure 5 is a perspective illustration of a collar forming part of the fairing
- Figure 7 is a section through the same assembly in a transverse plane.
- Figure 8 is a perspective illustration of a stage in the manufacture of a fairing body embodying the present invention.
- the fairing 2 illustrated in Figures 1 to 5 comprises (a) a fairing body 4 and (b) a plurality of
- collars 6 serving to rotatably couple the fairing body 4 to a cylindrical marine riser 8.
- the fairing body 4 can be seen to be generally wedge shaped. Its front, lying adjacent the riser
- the front face 12 of the fairing body is shaped to conform to the
- the illustrated embodiment has a pair of identically formed collars 6,6' at opposite ends of the
- each collar comprises a bearing ring 16 which is
- the collar is
- the ring on either side of the split 18 can be drawn apart - to allow the riser to be introduced.
- limb 26, 28 leading from each bifurcation forms part of the bearing loop and in use lies between the fairing body and the riser (see Figure 4) while the other limb 30, 32 extends in a
- the fairing body has shallow recesses or pockets in which the mounting
- tabs are received, so that the tabs' outer surfaces are generally flush with the adjacent faces
- plastics In order to resist corrosion and minimise weight these may be formed of plastics. However it is anticipated that during refinement of the product some other form of plastics
- the fairing may be
- the user first inserts the riser into the collars and then secures the relevant tabs to the other face 36.
- the fairing body is formed by a single plastics moulding. More specifically the illustrated
- Polythene is the preferred material for this component, which is advantageous due to its low specific gravity (similar to that of water), toughness and low cost.
- An opening 44 allows
- the collars are each formed by a single
- an anti-fouling composition which provides a controlled rate of release of copper ions, whose biocidal properties are well known, and also of silicon oil serving to reduce bearing friction.
- the internal part of the bearing on which the fairing is mounted may be provided by the riser itself. That is, the fairing may be mounted directly upon the riser (or on a cylindrical
- the clamps may be of a type well known in the context having a pair of half cylindrical clamp shells secured to the riser by a tension band passed around the shells.
- FIG. 6 An alternative arrangement can be understood from Figures 6 and 7 in which a clamp formed by two half cylindrical clamp shells 50, 52 is secured to the riser, again labelled 8 in this drawing, by a tension band 54 received in a shallow annular recess in the exterior of a central flange 56 formed by the clamp shells from either side of which project reduced diameter spigot portions 58 upon which the collars 60, 62 of respective fairings, arranged on opposite sides of the clamp, ride.
- the drawing is simplified in that remaining parts of the two fairings are omitted (they can be taken to be similarly formed to those of the previous embodiment).
