    Abstract: An arrangement for monitoring a submarine reservoir comprises a number of sensor units located in an array (1) on the seabed, and an interrogator unit for obtaining data on the reservoir from the sensor units. The interrogator unit comprises a transmitter unit (20) for sending optical signals to the sensor array and a receiver unit for receiving modulated optical signals from the array. Optical radiation from an optical source (22) is transmitted along an uplink optical fibre which is split in a number of positions 36, 38 to form the array. The receiver unit comprises optical - to - electrical converters (54) for converting the optical signals to electrical signals, a phase demodulator (58), a multiplexer (60) for multiplexing signals from the phase demodulator, a signal processor (68) and recording unit (70). The interrogator unit is divided into a concentrator that includes one or more of the splitters and optical - to - electrical converter, phase demodulator etc, and an interrogator hub that includes the optical source.

    Abstract: A fibre-optic package comprises at least two fibre optic devices or components (102, 104, 106, 118, 120, 122, 124) coupled together by fused-fibre coupling. The package typically comprises two or more fibre optic accelerometers, and may be of reduced size compared to fibre-optics packages of the prior art, due to the reduced length of optical fibre required to connect the devices or components.

    Abstract: The present invention provides an attitude sensing device and method for determining an attitude of a reference axis of a package (50) containing a fibre optic sensor (200). The attitude sensing device comprises an electro-mechanical attitude sensor (210, 215) for generating an electrical signal indicative of the attitude of that attitude sensor, and converter logic for converting the electrical signal into a stimulus signal. A local power source is preferably provided for the electro-mechanical attitude sensor (200, 215) in the converter logic. The stimulus signal is such that the fibre optic sensor (200) is responsive to the stimulus signal to cause a variation in at least one predetermined property of an optical signal transmitted through the fibre optic sensor (200), the attitude of the reference axis being determinable from the variation of the predetermined property. By this approach, it is possible to use the existing fibre optic sensor (200) within the package (50), along with the corresponding existing telemetry and multiplexing system, to recover the information from the electro-mechanical attitude sensor (210, 215).
