Definitions

  • the invention relates to a modular riser section storage and handling system for storing and handling riser sections which riser sections are adapted to be used in offshore wellbore drilling activities.
  • the invention further relates to a method for using such a modular riser section storage and handling system and a vessel comprising such a modular riser section storage and handling system.
  • Offshore wellbore drilling comprises placing a subsea template on a seabed, said subsea template may be a concrete slab with a hole that marks the wellbore.
  • a riser may be placed between the subsea template and a drilling vessel. The riser functions to protect the wellbore drill, allow mud and other residue to be carried off, and to allow subterranean gas or oil to be transported from the wellbore to the vessel.
  • the riser is constructed from riser sections.
  • a riser section comprises a riser pipe and additionally one or more auxiliary pipes, also called satellite, service, or peripheral pipes or lines, on the outside of and parallel along the riser pipe.
  • the auxiliary pipes are e.g. used as fluid lines, e.g. to a BOP or other subsea equipment, as choke line, kill line, hydraulic line, booster line, injection line (e.g. for glycol), etc.
  • the main riser pipe is provided at each end thereof with a radially extending flange, the main pipe and the flanges being made of steel.
  • One or both of the flanges may have bolt holes allowing to join riser sections by means of bolts and nuts.
  • An auxiliary pipe may have an individual connector fitting at its end or ends, e.g. a bayonet fitting, or be designed to fit sealingly into the auxiliary pipe of an adjoining riser section.
  • riser sections come in different lengths. Commonly riser sections have lengths between 50 ft. (15.24 meters) and 90 ft. (27.43 meters). A very common length for riser sections is 75 ft. (22.86 meters).
  • riser sections are commonly heavy; far heavier than other tubulars used in the offshore drilling industry.
  • a single 75 ft. subsea riser section may weigh between 20 and 25 tonnes, which is incomparable to the weight of an equally long drill pipe. Therefore riser handling is subject to different considerations than drill pipe handling, mainly in view of their size (diameter) and weight.
  • the riser sections typically are wide enough to facilitate the wellbore drill and allow passage of drilling residue, oil and/or gas.
  • the riser sections are typically provided with floating devices to enable the vessel to support the riser in the upright position.
  • typically one or more of the riser sections are telescopic riser sections.
  • the riser sections are stored on the deck of the drilling vessel.
  • Patent publication US 4,202,653 discloses a riser section storage and handling system including an overhead crane, supported on an overhead track, multiple type of rack bins comprising riser sections and drill pipe, and a riser section handling station for moving the riser in an axial direction towards and away from the rack bins.
  • the disclosed system is configured for storing and moving small diameter drill pipe, larger diameter casing pipe and still larger diameter riser pipe.
  • the some of the rack bins comprise guide channels for stacking riser sections.
  • the rack bins are fixed to the deck of the vessel. The deck thus forms part of the frame that provides the rack bins with structural integrity.
  • the overhead track is supported on vertical support beams, which vertical support beams are located outside the rack bins and are fixed to the deck of the vessel.
  • Patent publication WO 2018/172529 A1 discloses a method for providing a deck surface on an offshore drilling rig comprising installing a modular deck structure comprising a plurality of deck modules over at least a portion of a vertical riser storage bay provided for storing riser joints in a vertical orientation.
  • the modular deck structure is mounted on existing infrastructure within the riser storage bay.
  • Patent publication EP 0174055 discloses an arrangement for storing pipes in an offshore drilling installation below an upper deck carrying a derrick with associated equipment comprising a pipe magazine below the upper deck, a horizontal transport means for the individual displacement of riser sections between an aperture in the upper deck and storage means formed by a plurality of racks.
  • riser section storage on a vessel is typically designed to allow storage of the number of risers needed for the deepest sea in which the vessel is intended to be used.
  • a riser section storage adapted for storing a high number of riser sections thus costs a lot of valuable deck space.
  • Deck space is valuable because deck space is a limited commodity, and is used to store many equipment and utilities. Therefore, area of the deck space occupied with riser section storage is preferably kept to a minimum.
  • vessels are preferably used in seas with depths close to the maximum depth for which the vessel was designed. For example, when a vessel designed for use in deep sea is used in the relatively shallow North Sea a lot of deck space is occupied with empty riser storage. This deck space thus cannot be used for other ends and effectively represents a loss of money. Hence, this vessel is preferably not used in the North Sea.
  • Loading and unloading of riser sections may be a time consuming process and is preferably done as time efficient as possible. This is particularly true when a lot of riser sections have to be loaded or unloaded from the deck of a vessel, as may be the case when the wellbore is located in deeper sea. Loading riser sections on the vessel costs time in which the vessel is not used in a drilling operation, thus the owner of the vessel may be losing profit.
  • to provide a more versatile riser section storage and handling system which allows for more efficient use of deck space of the vessel. It is a further object of the invention to provide a riser section storage and handling system that allows for more efficient loading and unloading of the riser sections to and from the vessel.
  • the invention therefore provides a modular riser storage and handling system according to claim 1.
  • the riser storage and handling system comprises multiple riser section transport containers that are configured to be set up side to side in a storage configuration, and an overhead track for supporting the overhead crane.
  • the multiple riser section transport containers set up in the storage configuration support the overhead track, and thus enable the overhead crane to travel above and along the multiple transport containers in the storage configuration and to move riser sections between the multiple transport containers and the riser section handling station.
  • the multiple transport containers in combination with an overhead track comprising track sections enables a modular set up of the modular riser section storage handling system. Simply by providing more or less transport containers and a track composed of more or less track sections respectively allows for a modular riser section handling system having a large or small storage capacity and footprint.
  • transport containers for holding the riser sections facilitates transport of the riser sections, and also allows for transporting multiple riser sections at once, i.e. in one container that speeds up the transport.
  • utilising the transport containers for supporting the overhead track allows for an efficient set up, demounting, and adaptation of the modular riser section storage and handling system.
  • the multiple riser section transport containers in combination with the overhead track comprising multiple track sections thus allow for a versatile riser section storage system.
  • one or more of the multiple riser section transport containers may be mounted on the deck of the vessel.
  • one or more of the transport containers may be lifted from the deck of the vessel creating free deck space.
  • the freed up deck space may be used for other purposes such as storage of a well template.
  • the size of the footprint of the riser section storage system on the deck of the vessel is flexible and may be adjusted based on the number of riser sections needed in a particular well drilling operation.
  • the full modular riser section storage and handling system including the overhead crane and riser handling station may be lifted from the deck of the vessel completely freeing the deck of the vessel for other use and other purposes. Hence, the system allows for more versatile use of the deck space of the vessel.
  • the invention can be used with riser sections having lengths between 50 ft. (15.24 meters) and 90 ft. (27.43 meters), a very common length for riser sections is 75 ft. (22.86 meters), but may also be used with risers sections of great length, for example riser sections of at least 100 ft. (30.48 m), e.g. of 120 ft. (36.57 m) or 150 ft. (45.72 m).
  • Riser sections are typically provided with buoyancy means, due to which they have a comparatively large diameter compared to drilling tubulars.
  • riser sections may be placed in the riser section transport containers while the riser section transport containers are still on a shore and while the vessel is not yet ready to receive the riser sections. Placing the riser section transport containers containing the riser sections on the deck of the vessel allows for multiple riser sections to be loaded on the deck of the vessel at once. The riser sections may also be removed from the vessel using the riser section transport containers. This speeds up the process of loading and unloading of riser sections, increasing the efficiency of the loading and unloading process.
  • the invention comprises an overhead crane which is adapted to move along the overhead track for lifting and transporting riser sections, and which overhead crane can be removed from and can be placed on overhead track.
  • the overhead track for use by the overhead crane is formed by track sections that are located preferably on top of the riser section transport containers. Removal of riser section transport containers removes all or some track sections that form the overhead track. The length of the overhead track is thus flexible.
  • the invention allows for easy removal of the track, or sections thereof and the overhead crane, thus further increasing the versatility of the modular riser section storage and handling system.
  • the deck space occupied by the riser section handling system, embodied by the transport containers, the overhead crane and the overhead track, can thus be optimised for different well bore drilling operations depending on the number of riser sections needed.
  • Each track section may comprise two tracks components, which track components placed on opposite ends of the respective riser section transport container.
  • the track components are single beams. This allows for efficient support of the overhead crane.
  • the track may also comprise rollers or a pinion structure for supporting the overhead crane and allowing the overhead crane to move along the track.
  • the riser section transport containers each have a longitudinal axis extending from one end of the transport container to an opposite end of the transport container, and the top entry opening extends parallel to the longitudinal axis between the opposite ends of the container.
  • the container is configured to support at each end of the transport container, between the top entry opening and the ends of the transport container, a track section, the track sections extending parallel to each other and in a direction perpendicular to the longitudinal axis of the transport container.
  • the riser section transport container is a longitudinal container, having a longitudinal axis that extends between opposite ends of the container, and comprises a reinforced frame at each end and at opposite sides of the top entry opening of the container, which reinforced frames enable the container to support the track sections, and the overhead crane moving along that track section while supporting a riser section, and to transfer that load to the deck of the vessel.
  • the reinforced frames comprise connector devices for securing the transport containers to each other in the storage configuration and/or securing devices for securing the transport container to mounts in or on the deck of the vessel.
  • the reinforced frames comprise stacking frames, wherein said stacking frames are provided with stacking devices for supporting a stack of riser sections, for example three riser sections, one above the other.
  • the multiple riser section transport containers and preferably the riser section handling station, each comprise a track section, preferably on a top side of transport containers, preferably each track section comprising two track components located on opposite sides of the entry opening, such that when the transport containers are set up in the storage configuration the track sections form the overhead crane transport track.
  • the track sections are part of the transport container and preferably of the handling station.
  • the track sections are mounted on the transport containers, and preferably, the handling station, to compose the overhead track after the transport containers and the handling station are set up in the storage configuration.
  • track sections more in particular the components such as rails or beams making up the track sections, can be transported separately from the transport containers.
  • a single track section may extend from one transport container to another, may even extend over multiple containers, and thus bridge the area where two adjacent containers meat up. Such a configuration allows for single track sections, and may thus enable a continuous track with only a limited number of transitions between track sections.
  • the track sections may be configured to as connector devices for connecting adjacent riser section transport containers, and preferably the riser section handling station, when the multiple riser section transport containers, to thus secure the transport containers in the storage configuration.
  • the track sections may be integrated in the frame of the transport container or they may be placed separately on the top side of the riser section transport container.
  • the riser section handling station is adapted for handling riser sections and may receive riser sections from the overhead crane and prepare the riser sections for transport, preferably in an axial direction i.e. parallel to a longitudinal axis of the riser section, to a firing line of a well bore drilling operation on the deck of the vessel.
  • the riser sections may be transported to the riser section handling station by the overhead crane through for example a top side of the riser section handling station and further moved towards the firing line through an end or side of the riser section handling station.
  • Riser sections may also be transported from the firing line through the riser section handling station to a riser section transport container.
  • the riser section handling station may be located on an end of the modular riser section storage and handling system where a riser section transport container is only adjacent to one side, or the riser section handling station may be located in the modular riser section storage and handling system with riser section transport containers adjacent on two sides of the riser section handling system.
  • the most efficient configuration of the riser section transport containers and the riser handling station depends, among other things, on the side through which riser sections are transported from the riser section handling station.
  • the invention allows for a riser section storage and handling system having a versatile deck space footprint, which allows for a more efficient use of the deck of the vessel. Furthermore, the riser section handling system allows for a more efficient loading and unloading of riser sections on the vessel. This may reduce total time and cost of well bore drilling operations.
