Definitions
- the inventions disclosed and taught herein relate generally to oil and gas drilling and production equipment; and more specifically relate to an improved design and installation method for belly strakes useful for stabilizing floating, deep-water offshore oil and gas drilling and production platforms.
- Offshore oil and gas drilling and production operations can involve the provision of a vessel, or platform, sometimes called a rig, on which the drilling, production and storage equipment, together with the living quarters of the personnel manning the platform, if any, may be mounted.
- offshore platforms fall into one of two classes, that is, “fixed” and “floating” platforms.
- Fixed platforms often comprise an equipment deck supported by legs that can be seated directly or indirectly on the sea floor. While relatively stable, they are typically limited to relatively shallow waters, e.g., depths of about 500 feet (approximately 152 m) and less.
- at least one so-called “compliant piled tower” (CPT) platform which is referred to as the "Baldpate” tower, is said to be operating at a depth of 1648 ft. (approximately 500 m).
- Floating platforms are typically employed in water depths of about 500 ft. (approximately 152 m) and greater, and may be held in position over the well site by, as examples, mooring lines anchored to the sea floor, motorized thrusters located on the sides of the platform or both.
- floating platforms may be more complex to operate because of their movement in response to environmental conditions, such as wind and water movement, they are generally capable of operating in substantially greater water depths than are fixed platforms.
- Floating platforms may also be more mobile, and hence, easier to move to other well sites.
- There are several different types of known floating platforms such as, for example, so-called “drill ships,” tension-leg platforms (TLPs), semi-submersibles, and spar platforms.
- Spar platforms for example, comprise long, slender, buoyant hulls that give them the appearance of a column, or spar, when floating in an upright, operating position, in which an upper portion extends above the waterline and a lower portion is submerged below it. Because of their relatively slender, elongated shape, they have relatively deeper drafts, and hence, substantially better heave characteristics, e.g., much longer natural periods in heave, than other types of platforms. Accordingly, spar platforms have been thought of by some as a relatively successful platform design over the years. Examples of spar-type floating platforms used for oil and gas exploration, drilling, production, storage, and gas flaring operations may be found in the patent literature in, e.g., U.S. Pat. No.
- spar-type platforms include some aspects that need improvement.
- they can be relatively more complex to manage during offshore operations under some conditions than other types of platforms in terms of, for example, control over their trim and stability.
- spar platforms may be particularly susceptible to vortex-induced vibrations (VIV), which may result from strong water currents acting on the hull of the platform.
- VIV vortex-induced vibrations
- the provision of apparatus on the elongated hulls for vortex breaking, or controlled vortex-shedding, can reduce or eliminate this problem.
- U.S. Pat. Nos. 6,148,751 and 6,349,664 to Brown et al.
- the first possibility may include towing the spar on the surface of the water, such as with tug boats, for a "wet tow" transport.
- the belly strakes may be installed around the hull if the draft of the hull plus the strake panel width does not exceed the yard and the ship channel water depth, normally 45 ft. (14 m).
- the draft in the yard and/or ship channel may be low, which may make it difficult or impossible to have the fully extended strakes around the hull.
- the second possibility may include towing the spar on a Heavy Lift Vessel ("HLV”) for a "dry tow" transport.
- HBV Heavy Lift Vessel
- the spar hull is dry transported using a HLV from a remote fabrication yard to a near fabrication yard.
- the final outfitting will be completed in a near fabrication yard.
- the final outfitting may include removal of dry tow transportation supports and aids, installation of remaining wet tow aids and lightweight survey of the hull.
- the hull will be wet towed to the offshore site.
- the belly strakes can be installed in the quayside of the yard by rotating the spar hull.
- the belly stake may need to be installed offshore due to the limited water depth of the ship channel, for example.
- the inventions disclosed and taught herein are directed to an improved system and method for designing and installing a belly strake for a spar with a large diameter hull.
- a spar hull for a floating vessel may include a hard tank having an outer surface, which can include a belly portion, a fixed strake and a folding strake configured to be selectively folded toward the outer surface of the tank.
- the strakes can be coupled to any portion of the spar hull, such as the outer surface of the hard tank.
- the folding strake can have one or more strake panels, which can be coupled, such as for rotation, to one or more portions of the spar hull, for example, to a belly side.
- the folding strake can have one or more folded or unfolded positions and can include structure for locking the strake in one or more positions.
- the folding strake can include one or more strake panels and support frames, each of which can, but need not, be configured to be coupled, such as rotatably, to the side of the spar hull.
- one or more support frames can be coupled to the side of the spar hull and the strake panels rotatably coupled to the support frames that collectively form a strake surface when the strake panels are unfolded.
- the panels and/or frames can have one or more folded or unfolded positions and the support frame can, but need not, be configured to support the strake panel, directly or otherwise, when the frame and/or panel are in one or more respective unfolded positions.
- a method for utilizing belly strakes on a spar hull for floating vessels can include providing a floating spar having a hard tank and a belly side, transporting the spar to a deep water pit, rotating the spar so that the belly side is in a first workable position, which can be any position, and coupling at least one folding strake to the belly side of the spar.
- the method may further include fixing the strake in a folded position, such as for transport or tow, and rotating the spar to a second position, such as for wet tow transport.
- the folding belly strake may include one or more frames and/or panels, which may be fitted or removed before transport or final positioning.
- the method may include unfolding one or more components of the strake and coupling those components in a position for operations, fixed or otherwise.
- a method of utilizing a spar hull for offshore oil and gas operations may include providing a spar hull having a belly strake, wherein at least a portion of the belly strake has folded and unfolded positions, fixing the strake in the folded position, positioning the spar hull offshore in a transport position, upending the spar hull, unfolding the strake, fixing the strake in an unfolded position and positioning the spar hull in the installed position.
- Unfolding the strake may include unfolding one or more support frames and/or strake panels.
- Applicants have invented a belly strake system, design and installation method for a spar having a large diameter spar hull.
- the spar hull without the belly strake may be towed, for example, dry towed on a heavy lift vessel (HLV), from a fabrication yard to a float-off site.
- the spar hull can be offloaded at the float-off site, for example, into a deep water-filled pit or tank (such as a 77 ft. (23 m) deep water pit in Kiewit Offshore Services yard, Texas, USA) for preparing or outfitting the spar hull for operations.
- a deep water-filled pit or tank such as a 77 ft. (23 m) deep water pit in Kiewit Offshore Services yard, Texas, USA
- the hull can be rolled about its longitudinal axis, for example, 180°with its bare belly side upward in the pit, for allowing access to a portion of the hull where a strake may be coupled thereto.
- a belly strake such as a foldable strake, can be installed on the belly side in the quayside.
- the spar hull can be rolled back toward or to its original position with the strake and belly side toward the sea bed or other bottom of the deep water pit and towed to another site, such as its permanent site for operations.
- the tow can pass through a shallow water depth zone, such as a 45 ft. (14 m) deep channel, for example. Once the spar arrives at a location for operations, it can be upended.
- the strake panels can be unfolded and fixed in place, such as by installing fasteners to lock the strake panels into an unfolded position.
- One or more support frames can be utilized to support the strake panels, and in some embodiments, the support frames can be folded, as well.
- the systems and methods described herein can reduce the time and costs associated with the installation and use of belly strakes on spar hulls.
- installing the foldable strake panels on the quayside can reduce or eliminate offshore swage, grouting, or other steps, and the time and costs associate therewith.
- Another of many advantages of the present invention may include improvement of the dimension control associated with strakes or spar hulls.
- the present inventions can allow the folded support frames and/or folded strake panels to be unfolded in the yard, such as for performing one or more system integration tests (SITs).
- SITs system integration tests
- the strake supports and panels can be folded and temporarily coupled to the hull, such as with temporary sea fastening.
- This can allow, for example, the strake panels to be quickly and accurately installed on the strake support frame during offshore operations, which may help ensure safety and efficiency.
- the present inventions may eliminate the need for a lifting vessel for strake panel installation at the site of operations, such as the permanent rig site, which can significantly reduce operations costs.

- a second coupler 316B can be used couple together an inward portion of the panels that is proximal to the hull.
- the number of couplers can vary from one to many and the illustrated number is only exemplary.
- couplers are shown engaged with the panels 304A and 304B coupled together.
- the portions of the coupler are shown uncoupled, and thereby the panels 304A, 304B are also uncoupled. More specifically, as shown in FIG.
- the coupler 316B can include a first portion 340 that is coupled to the panel 304A and a second portion 342 that is coupled to the panel 304B.
- a latch 344 can be rotatably coupled to the first portion 340 about a pivot 346 and can be held in such position by a fastener 348.
- the second portion 342 of the coupler 316 acts as a receiver and can receive the latch 344, when the latch 344 is rotated toward the second portion 342.
- a fastener 350 can be inserted through an opening 352 formed in the latch 344, to secure the latch with the second portion 342. The opening is illustrated in FIG. 11B and a secured latch is illustrated in FIG. 11A .
- FIG. 12 illustrates one of many embodiments of a spar 100 in an installed position and utilizing certain aspects of the present inventions.
- spar 100 can be positioned for operations, such as, for example, in the final or operations position shown in FIG. 12 .
- moor lines 802 can be coupled to hull 104 or other portions of spar 100, such as to anchor spar 100 to the sea floor.
- one or more decks 804 or cranes 806 can be coupled to spar 100, separately or in combination with any other drilling or operations equipment required by a particular application. While the contour of folding strake 302 is shown in FIG.
- strakes 106, 302 are shown in FIG. 12 to be coupled in a helical fashion about spar 100, it need not be, and can take any form or fashion.
- strake can be folding strake or the folding strake can be folded or unfolded automatically, such as by pistons.
- the various methods and embodiments of the spar can be included in combination with each other to produce variations of the disclosed methods and embodiments. Discussion of singular elements can include plural elements and vice-versa.
