Description
SEALING PROTECTOR APPARATUS
The present invention relates generally to the field of subsea pipelines and manifolds, and in particuhr, to an apparatus and method for protecting umbilicas and further adapted to improve safety management of kickbacks or blowouts of hydrocarbons, and in particular natura' gasses) in offshore production systems.
INTRODUCTION
Often, hydrocarbons, such as oil and gas, are deposited in rock formation ocated beneath the seabed. Thus, in order to explore and produce the hydrocarbons, wellbores, associated ancillary equipment and pipelines have to be installed subsea.
The wellbore-and ancillary equipment, such as seabed pipelines and pigging equipment (Pipeline Inspection Gauge], generally require the use of high-pressure lines/hoses, couplings and valves, in order to manage fluid flow (e.g hydrocarbons, drilling fluids etc.) between the reservoir and offshore production facilities, such as a platform or vessel.
Figure 1 shows a typical offshore production setup where a floating platform 10 (a'so known as "rig"] is located on the surface. A large diameter pipe 12, also known as a riser, is provided to connect the reservoir with the stack with the platform 10 via a lMowout preventer (BOP) 14 and a diverter 16.
The riser 12 is used to return the drilling mud and/or cuttings to the surface. The riser 12 is large enough to allow the drill pipe 18, logging tools (not shown] and multiple casing strings (not shown] to pass through. The BOP 14, usually placed at the seafloor between the wellhead and the riser 12, provides protection against over-pressured formations and sudden releases of gas. The diverter 16 is adapted to divert shallow gas through overboard pipelines 20 and/or vent gas in the riser above the BOP 14. In the event of, for example, a shallow gas kick, the diverter 16 is energized to seal around the drill pipe 18 and divert the gas safely overboard or into a suitable storage. The diverter 16 may deploy a bag or packer mechanism to provide the seal around the drill pipe 18.
However, there is a known risk that the diverter system 16 may not conform around the umbilicals and/or auxiliary lines 22, which are running on the outside of the drill pipe 18, during final completion and workover operations. In some cases, an "annular kick" from the riser 12 may result in catastrophic consequences. Of particular risk are deep water applications, where kick detection and subsequent deployment of the lower BOP 14 may be too late allowing a high-volume gas kick to emerge and move towards the diverter 16, potentially endangering any personnel in close vicinity.
Currently, these problems / risks are addressed using so called riser sealing mandrels 24 that are installed around the drill pipe 18 and umbilicals 22. However) typical riser sealing mandrels are made of a relatively long metal body having a substantial weight making its handling and installation extremely difficult Therefore, such metal riser sealing mandrels require a considerable amount of handling equipment providing further problems in the relatively tight space available on the platform floor. Accordingly) the difficult handling and installation) as well as, the equipment required to handle the metal riser sealing mandrels proves to be also very time consuming) resulting in significant rig downtime, making the installation of such riser sealing mandrels costly.
In addition, other currently available wear protector systems are not able to provide a true gastight seal in order to prevent) for example, high volume gas kicks to potentially break through the diverter system 16) putting personnel and equipment at risk. Also) sealing mandrels and other protector systems are not yet an established standard to be used in riser systems.
Although, in response to recent accidents/incidents (e.g. BP incident in the Gulf of Mexico], the oil & gas industry has become much more safety conscious and is therefore considering to utilise and deploy many more sealing and protector systems, especially as the trend to even deeper subsea depths continues.
Accordingly, there is a need for a llghtweight and/or modular protector apparatus, such as a cable protector, capable of providing a true gastight seal when in situ with a diverter system of BOP. Therefore, it is an object of the present invention to provide a modular protector apparatus comprising a gastight seal adapted to prevent fluid, such as gas, to pass through when in engagement with the barrier provided in situ with a diverter or BOP.
SUMMARY OF THE INVENTION
Preferred embodiments of the invention seek to overcome one or more of the
disadvantages of the prior art.
According to a first aspect of the present invention, there is provided a protector apparatus for protecting at least one cable during operation of a diverter, comprising: a plurality of protector assemblies) each comprising at least a first protector component and a second protector component defining a first bore and at least one second bore along a longitudinal first axis, said first bore being adapted to receive and operatively attach to a string of tubulars, and said at least one second bore being adapted to receive an umbilical, wherein each one of said plurality of protector assemblies is interlockable to at least one longitudinally arranged adjacent one of said plurality of protector assemblies to form said protector apparatus, and wherein each one of said plurality of protector assemblies further comprises at least one first sealing element adapted to engage with said first and second protector component so as to prevent fluid flow through said plurality of protector assemblies in a direction along said longitudinal first axis when in situ.
This provides the advantage of providing a true gastight seal through the protector apparatus when in situ. In particular, the sealing elements are arranges so as to not affect the functionality and modularity of the apparatus, therefore providing significantly improved handling and installation, as well as, adaptability of this "riser sealing mandrel"-type apparatus. Thus, improved handling and installation as well as the modular character and lightweight material, eliminates the need for large handling equipment, subsequently minimising rig downtime and maximising its cost efficiency.
The first and second protector components may be moveable with respect to each other between a first disposition, where the string of tubulars and umbilical can be moved into respective said first bore and said second bore, and a second disposition, where removal of the string and umbilical from respective said first bore and said at least one second bore is prevented. Advantageously, the first protector component may comprise a first contact surface and said second protector component may comprise a second contact surface arranged so as to matingly face said first contact surface when in said second disposition. Suitably, the first contact surface and said second contact surface may define said first bore and said at least one second bore when in said second disposition.
This provides the advantage of an even further increased modularity improving ease of use and installation time.
Advantageously, the first contact surface and said second contact surface may sealingly engage said at least one first sealing element when in said second disposition. Even more advantageously, the at least one first sealing element may be arranged between said first contact surface and said second contact surface in a direction along a second axis, that is perpendicular to said longitudinal first axis, when in said second disposition. Preferably, the at least one first sealing element may cover the entire width of the mating regions of said first and second contact surface.
S
This provides the advantage that the pressure generated by the two components when closed around, for example, the drill pipe and one or more umbilicals, is applied to the sealing elements, thus compressing the sealing elements and subsequently improving the seal between the two components.
Advantageously, the at least one first sealing element may be attached to said first or second contact surface via an adhesive.
Alternatively, the at least one first sealing element may be removably attached to said first or second contact surface via a groove on respective said first and/or said second contact surface.
This provides the advantage that the sealing elements are easily exchangeable in the event of damage or wear and tear.
Advantageously, the atleast one first sealing element may be located in a region at a bottom end of each one of said plurality of protector assemblies when in situ. Even more advantageously) each one of said plurality of protector assemblies may comprise at least one second sealing element located in a region at a top end of each one of said plurality of protector assemblies when in situ.
Preferably, at least one of said at least one first and second sealing element of at least one of said plurality of said protector assemblies may be located within a longitudinally defined region of the diverter when in engagement with an external surface of said protector apparatus in situ.
Advantageously, said first bore may have a profile adapted to provide a sealingly snug fit around a portion of the string of tubulars. Even more advantageously, said at least one second bore may have a profile adapted to provide a sealingly snug fit around a portion of an umbilical.
This provides the advantage that the sealing engagement of the first and second bore with the umbilical, e.g. a cable) complements the sealing elements provided between the mating surfaces of the two protector components, ensuring a gastight seal through the protector apparatus.
Each one of said plurality of protector assemblies may further comprise a third protector component adapted to be assembled with said first and second protector component so as to define said first bore when in engagement with said first protector component, and so as to define said at least one second bore when in engagement with said second protector component. Advantageously, the third protector component may comprise a third contact surface arranged to matingly face said first contact surface of said first protector component) and a fourth contact surface adapted to matingly face said second contact surface of said second protector component. Even more advantageously) the first) second and third protector components may be moveable with respect to each other between a first disposition, where the umbilical and or string of tubulars can be moved into respective said at least one second bore and first bore) and a second disposition) where removal of the umbilical and/or string of tubulars from respective said at least one second bore and said first bore is prevented.
This provides the advantage of an even further increased modularity of the protector apparatus, thus improving ease of use.
Advantageously, the external surface defined by each one of said plurality of protector assemblies maybe curved. This provides the advantage of a snug sealing engagement with the bag or packer deployed by the diverter in the event of a kick.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In accordance with the preferred embodiment of the present invention, Figure 2 depicts a protector apparatus 100 that has been assembled to a predetermined length using thirteen centre protector assemblies 102, a first end protector assembly 104 and a second end protector assembly 106. As shown in Figure 3, each of the centre protector assemblies 102 has a female interlocking portion 108 on one side and a male interlocking portion 110 on its opposing other side. Female and male interlocking portions are formed so as to matingly interlock, allowing any number of centre protector assemblies 102 to be assembled to any required length.
The first end protector assembly 104 has a male interlocking portion 110 on one end and a chamfer 112 on the other opposing end. The second end protector assembly 106 has a female interlocking portion 108 on one end and a chamfer 112 on the opposing other end. All of the assemblies 102, 104 and 106 are interchangeable and can be assembled into a protector apparatus 100 of any
suitable length.
Referring now to Figure 4, an example of a centre protector assembly 102 is shown in an exploded view separating a first protector component 114, a second protector component 116 and the third protector component 118 of the centre protector assembly 102. First and second end protector assembly 104, 106 comprise a first) second and third protector components (not shown in detail) likewise to the first) second and third protector component 114, 116 and 118 of the centre assembly 102, and are therefore not described in any further detail.
First, second and third protector component 114, 116, 118 are assembled and fastened to each other by four fastener members 120. For example, the fastener member 120 may be a threaded bolt that passes through respective holes 124, 126 of the second and third protector component 116, 118, and fixedly screws into a suitable thread 128 arranged in said first protector component 114.
First and third protector components 114, 118, when assembled, define a first bore suitaNe for receiving a string of tubukrs (not shown), such as a drill pipe. The diameter of the first bore 130 shoukl be suitaNe to snugly fit around the string of tubulars, i.e. via an interference fit. Second and third components 116, 118, when assembled, define a second and third bore 132, 134 suitable for receiving umbilicas (not shown], such as cables. Second and third bores 132, 134 may be of different diameter to accommodate for different sized umbilicals. Second and third bores 132, 134 are dimensioned so as to snugly fit around respective umbilical, i.e. via an interference fit.
Each of the three protector components 114, 116 and 116 is moveable bodily in relation to its mating protector component, between a first disposition, where a string of tubulars and/or umbilical(s) can be received in respective first, second and third bores 130, 132, 134, and a second disposition, where the removal of the string of tubulars and/or umbilical(s) is prevented. The individua' protector components 114, 116 and 118 maybe hinged to its respective mating protector component so as to allow pivotal movement between respective mating protector components. For example, the pivot may be along the longitudinal edge of any of the contact surfaces 136, 138, 140, 142 of the three protector components, i.e. 114 and 118 and/or 116 and 118. Alternatively, the three protector components 114, 116 and 118 may simply be separate components to be assembled into any of the protector assemblies 102, 104 and 106.
Each of the protector assemblies 102, 104, 106 forms a substantially cylindrical outer surface to maximise the contact surface and sealing engagement with a diverter or BOP during actuation, i.e. when the diverter shuts around the installed protector apparatus 100 to seal off the riser region downhole of the diverter or BOP.
First and second sealing elements 200, 202 are arranged between respective contact surfaces 136/138 and 140/142 in an upper end region and a bottom end region of any one of the protector assemblies 102, 104, 106, covering the full width of the engaging contact surfaces 136/138 and 140/142. In this particular embodiment, the first and second sealing elements 200, 202 are removably arranged in suitable grooves 204, 206 arranged in any one or all of the contact surfaces 136, 138, 140, 142. Alternatively, the sealing elements 200, 202 may be attached to respective contact surfaces 136, 138, 140, 142 via an adhesive, such as for example a glue. In another alternative embodiment, the first and or second sealing element(s) 200, 202 may be arranged so as to cover the whole area of the respective mating surfaces 136/238 and 140/142.
It is understood by the person skilled in the art that first and second sealing element 200, 202 may be made of any suitable sealing material. For example, first and second sealing element 200, 202 may be made of any elastic polymer, such as rubber or silicone rubber, but may also include any other mechanical sealing material suitable to sealing engage two mating surfaces under contact pressure (e.g gasket). Also, any suitable fastener may be used to assemble and fix any of the protector components.
Preferably, each of the first second and third protector components 114, 116 and 118 are made of a tough and high impact wear resistant polymer material. The natural properties of the polymer provides a low weight, safe and easy to handle protector apparatus 100 that is very resilient, but also much "kinder" to all other equipment such as wellheads, tubular handling equipment, marine riser etc. As a result of the weight benefits, the protector apparatus 100 may incorporate a geometrically optimised design without the need for any special fitting or lifting aids.
During installation, first and third protector component 114, 118 may be first fitted around the string of tubulars (e.g. drill pipe) so that the string of tubulars is received in the first bore 130. The umbilicals are then placed in respective second and third bores 132, 134 of the third protector component 118 and covered with the second protector component 116 so as to form a centre protector assembly 102. Any number of centre protector assemblies 102 may be interlockingly fitted to the string of tubulars and umbilicals. When the desired length is reached, first and second end protector assemblies 104, 106 are fitted to opposing ends to complete the installation.
In order to ensure that the sealing elements 200, 202 of the protector apparatus 100 seahngly cooperate with the diverter actuators when engaging with the outer surface of the protector apparatus 100,, the dimensions of the protector assemblies and resulting distances between the first and second sealing elements 200, 202 are suitable that there is always at least one of the first and second sealing elements 200, 202 placed in the engaging region of the diverter actuator (e.g. the packer or sealing bag). For example, the diverter actuator may have a thickness of about 600 mm, wherein the sealing elements 200, 202 are arranged in 300 mm intervals.
A typical assembly of a protector apparatus 100 around two umbilicals 300, 302 is shown in Figure 5.
In yet another alternative embodiment, the protector apparatus may only comprise a first and second protector component adapted to define a first bore for receiving the string of tubulars, and at least a second bore for receiving at least one umbilical.
The two protector components are fitted around the string of tubulars and umbilical(s) and fastened by suitable fasteners (e.g. threaded bolts) clamps etc).
First and second sealing elements are arranged in an upper and lower end region of each one of the protector assemblies so as to prevent any fluid flow in a longitudinal direction through the protector assembly, when in situ. Figures 6 and 7 show an example of a protector apparatus 400 having two protector components 414 and 416. Figure 6 depicts (a) a centre protector assembly 402 and an end protector assembly 404. Figure 7 depicts (a) a front view and (b) a cross sectioned side view of the alternative protector assembly 400 when installed around a string of tubulars 500. Figure 6 (b) and Figure 7 (a) also show handle members 406 that may be removably attached to the protector assembly 400 to improve the handling of the protector assembly 100, 400 during installation / de-installation.
It will be appreciated by persons skilled in the art that the above embodiments have been described by way of examp'e only and not in any limitative sense, and that various alterations and modifications are possible without departing from the scope of the invention as defined bythe appended daims.
