  • the present invention relates to monitoring of subsea installations and in particular, though not exclusively, to a subsea deployment system based on a wireless monitoring system for use in the controlled deployment of a portion of a subsea installation onto a fixed subsea structure.
  • WO201 1 /1 141 52 to the present Applicant's describes a wireless auxiliary system for monitoring and control of an underwater installation.
  • Data and control signals are sent between a lower stack in a hydrocarbon drilling or production facility and an associated riser assembly.
  • Data is collected by locally powered sensors on the fixed lower stack and transmitted via an umbilical to surface.
  • the data is sent from a first transceiver located on the stack to a second transceiver located on the riser assembly by electromagnetic signals. This allows wireless transfer to occur between the lower stack and the riser assembly after the riser assembly is detached or just prior to reattachment. Such detachment and reattachment is required during periods of bad weather when the riser assembly can move significantly due to it's attachment to a topside floating rig or vessel.
  • WO201 1 /1 141 52 provides for the transmission of sensor data during detachment and reattachment of a riser assembly to a lower stack on an operating subsea well. It does not assist in the speed or guidance of the detachment or reattachment. Yet further it is limited to transferring data only during detachment and reattachment. It is an object of the present invention to provide a subsea deployment system based on a wireless monitoring system for the controlled deployment of a portion of a subsea installation onto a fixed subsea structure.

  • the underwater vehicle is a remotely operated vehicle (ROV).
  • Such vehicles are already used in a subsea environment and can be guided to a wellhead or other subsea location of a well.
  • the data is transmitted as an electromagnetic and/or magneto-inductive signal. Signals based on electrical and electromagnetic fields are rapidly attenuated in water due to its partially electrically conductive nature. Propagating radio or electromagnetic waves are a result of an interaction between the electric and magnetic fields.
  • seawater provides attenuation losses in a workable bandwidth which provides for data transmission over practical distances.
  • the data may be compressed prior to transmission. Compression allows the occupied transmission bandwidth to be reduced. In this way, increased data rates can be transmitted over equivalent distances.
  • the data is compressed in combination with use of a lower carrier frequency.
  • the lower carrier frequency leads to lower attenuation. This in turn allows data transfer through fluids over greater transmission distances. In this way the data compression and carrier frequency can be adjusted as the parts are brought together so that increased data is transmitted at closer distances.
  • the data is also transmitted by an acoustic signal.
  • Acoustic signals can best carry low data rates over large distances.
  • acoustic signals may transmit data between the vehicle and the parts to provide guidance and positioning data across thousands of metres to both assist in deploying the second part and in steering the underwater vehicle to the first part.
  • the signals can be switched over to electromagnetic and/or magneto-inductive signals to increase the data rate. Both signals may operate for a period with the data being compared to provide error correction and analysis for improved reliability.
  • the signal is also transmitted by an optical signal.
  • Optical signals offer large data rates but are effective only across short ranges.
  • the optical signals are used at distances of less than 5 metres but most preferably at a few centimetres and below through seawater.
  • Electromagnetic and/or magneto- inductive signals and optical signals may operate with the data being compared to provide error correction and analysis for improved reliability.
  • the data transmission is bi-directional.
  • command and control signals can be transferred between the vehicle and the parts.
