Definitions
- the present invention relates to a method and an installation for monitoring and controlling an articulated fluid transfer arm with an emergency disconnection device, intended to connect and connect a ship to a platform at sea.
- the known document FR-A-2 347 159 describes a logical system for monitoring an articulated fluid transfer arm, comparing an isolated signal with a predetermined limit without taking account of the preceding information.
- the present invention relates to a logic system comparing the statistical parameters of a sample of signals with a predetermined limit.
- the invention meets these various imperatives and constraints by ensuring, in particular, either the stopping of all circulation of fluid, or the emergency disconnection.
- the values of the signals from the computer approaching the alarm envelope are used to trigger the alarm.
- the signal values of the computer approaching the intervention envelope produce an semi-automatic alarm for the operator, who can act on a device for stopping the circulation of fluid in the transfer arm and, in automatic, produce the direct action of sealing means of said pipe.
- the invention also relates to an installation for monitoring and controlling an articulated fluid transfer arm intended to connect and connect a ship to a platform at sea and implementing the above method.
- the installation comprises, in addition to the computer, sensor means allowing constant monitoring of the parameters to which the ship is exposed simply moored to the platform.
- the boom is, during loading operations, substantially in a horizontal position and has two degrees of freedom: - a rotation relative to a vertical axis secured to the platform, which rotation allows the arm to follow the horizontal drift of the ship ; and - a rotation relative to a horizontal axis integral with the platform, which rotation allows the arm to rise or lower to follow the vertical drift (due mainly to the tide) of the ship.
- an oil tanker (T) is shown connected to an offshore platform (P) by means of a simple hawser or mooring (A).
- A On the arrow (F) of said platform hangs an articulated fluid transfer arm (L) itself connected at a theoretical point (M) of the ship.
- the articulated arm (L) can be of any suitable type and is provided with at least one device for stopping the circulation of fluid (not shown) and a device for emergency disconnection (1 ) of which a part (1A) is integral with the ship (T) ( Figure 2).
- the articulated arm suspended from the arrow is of the accordion or zigzag type, but it is obvious that this choice is in no way restrictive.
- the arrow (F) can rotate around a vertical axis and around a horizontal axis.
- the vessel (T) is subject to continual variations in the sea state and the connection point (M) considered is illustrative, according to three degrees of freedom (H-SW-SU) of the movements of the vessel resulting from variations in this state sea.
- H-SW-SU degrees of freedom
- the point (M) is part of a plane, preferably pendulum, in which is located the articulated arm (L) and all angular or linear displacements of said pendular plane correspond to variable coordinates in the space of the point (M); the axis OX being taken as corresponding to the longitudinal axis of the ship.
- variable coordinates of point (M) can be measured at all appropriate points; on the arm (L), on the boom (F) of the platform or on the ship itself.
- the sea state intervenes mainly on the angular displacements and the linear displacements of the ship.
- the phenomena which characterize it can be of slow or fast action vary in time and according to the places of the globe where we are. This is how tides and currents cause rather slow linear movements while the waves cause rather rapid linear and angular movements of the ship.
- the amplitude and the duration of these oscillations depend in fact on several factors and on the relationship with each other (dimensions, direction and speed of propagation of the swell; dimensions, inertia and righting moment of the ship, etc.).
- the ship itself therefore constitutes in itself an important factor, determined by its dimensions, its type of construction, its resistance to the sea as to that of the wind and depending on whether it is in an empty or loaded state.
- the most complete possible set of these various data and these various events of variable frequency (regular or irregular, fortuitous or rare) occurring in various places and of variable importance in the scale of the potential risks of damage and accidents that they represent is inventoried and analyzed statistically and supplied in memory to a computer or other calculator.
- the computer accumulates in memory the information supplied by sensors in order to statistically process a representative sample of the situation. In order to reflect the evolution of the situation, the sample is periodically renewed, the oldest information being rejected to make room for the most recent information.
- movements (H'-SW'-SU ') having a frequency of the order of that of the wave are said to be “rapid movements” and movements (H “-SW” ) having a period much longer than that of the wave (or constant) are called “slow movements”.
- the arm (L) takes account of the movements (H'-SW'-SU ') while the arrow (F) takes account of the movements (H "-SW").
- the computer discriminates slow horizontal displacements in particular by analysis by digital filter, and the result of this operation is the displacement of the arrow to compensate for the drift.
- the measured values of the variable angular displacements of the point (M) considered on the ship, like the variable linear displacements of this same point (M) are continuously supplied to the computer.
- One of the tasks of the computer is then to continuously compare the information acquired from statistical analysis (AS) information with the information it constantly receives from measurement sensors. From the result of this continuous comparison, the computer provides usable signals, either semi-automatic or automatic, on the circulation of the fluid in the transfer arm (circulation stop device) or on the emergency disconnection. (emergency disconnection device) and sufficiently in advance to take into account the inertia of these fluid circulation stop and emergency disconnection devices.
- AS statistical analysis
- one or more limit thresholds (S1-S2-S3) are imposed on the computer so that the approach of these thresholds generates a triggering of an alarm or a triggering of 'an operation, by one or more of the operating signals supplied by the computer.
- An operating criterion imposed by the invention is therefore to force the point (M) to remain inside a volume delimited by a surface called “capable envelope”.
- a work envelope which is a closed surface containing all the possible trajectories of the point (M) is calculated with a given probability of crossing (for example it can be agreed that the probability for the point (M) of crossing the 'work envelope in ten years is less than 1/100).
- the fluid transfer arm is calculated so that the working envelope is inscribed entirely inside the capable envelope of the arm.
- the function of the computer is to ensure that point (M) never crosses the working envelope S (a, ⁇ , 0). Since for given p, ⁇ , y coordinates, the point (M) is fixed, it is possible to determine the coordinates of (M) in a system centered in (Mo). When the arm is disconnected, the point (M) returns to a position (R) which is a rest position.
- the movements of the point (M) are measured before, during and after the connection of the arm (L) to the vessel (T).
- the arrow (F) is substantially in a horizontal position and has two degrees of freedom: - a rotation relative to a vertical axis secured to the platform, which rotation allows the arm (L) to follow the horizontal drift of the ship; and- a rotation with respect to a horizontal axis integral with the platform, which rotation allows the arm to rise or lower to follow the vertical drift (due mainly to the tide) of the ship.
- Two accelerometers (Acc 1 and Acc 2) are provided to measure the vertical movement (direction Z) and the horizontal movement (direction Y only).
- the sensitive axes of the accelerometers are preferably mounted on a stabilized platform or with Cardan joint.
- the acceleration signals are integrated twice.
- this is preferably transformed into a low frequency square wave signal, amplitude modulated. This low-frequency signal is then demodulated to obtain an exploitable signal. It is thus possible to do without any electric transmission cable and to use a low energy.
- the instrumentation can be installed on the moorings of a buoy subjected to the wave, which constitutes, in itself, a reliable means allowing the measurement of the vertical movement of the sea.
- the geometry of the articulated arm is determined by several angles using potentiometric means.
- the measurement of the angles a, ⁇ , y allows the determination of the coordinates X, Y, Z of the point (P) located at the point of connection of the articulated arm with the loading connector.
- the determination of the point (P) is considered sufficient by measuring only the angles a, ⁇ , y .
- the measuring instruments can be constituted by four potentiometers (P01-P02-P03-P04) intended to measure the angles a, ⁇ , y, ⁇ .
- the first of these potentiometers is installed on the articulated arm (L) and the fourth on the ship (T).
- An electrical connection is provided between the vessel and the articulated arm to connect the fourth potentiometer and this connection is waterproof.
- the potentiometers are installed in watertight boxes, of robust construction with sealed axis passage.
- the output signal from each potentiometer is a voltage proportional to the angle measured.
- two sets of four potentiometers each are provided in order to increase the security of the measurements.
- the readings can be compared and crossed if necessary by comparison of eight groups of three readings each for the angles a, ⁇ , y.
- the invention applies whether or not the arm L is connected to the ship (T).
- the movement of the point (M) at the front of the ship can be determined, according to one embodiment, by the combination of two cameras, both fixed to the arrow (F), one at the end of the arrow (camera A), the other at the base of the arrow (camera B).
- a transmitting diode is required at the front of the ship at a point close to point M.
- the two cameras are directed at this point and the combination of the two measurement forms provides the three-dimensional movement of the front of the ship relative to a system of references taken from the arrow (F).
- the two cameras are installed so that they can "see” the point (M) regardless of the position of the articulated arm (L).
- X, Y and Z are the coordinates relative to a reference system taken on the arrow (with the horizontal OY axis).
- the cameras are placed in waterproof boxes and fitted with windscreen wipers.
- optical axes of the two cameras are preferably in the same plane.
- the power of the emitting diode and the aperture ratio of the lenses are calculated as a function of the distance from the point (M) and the detector of each camera is also calculated accordingly.
- a single camera placed at the end of the arrow (camera A).
- This camera is mounted on the gimbal and looks down, vertically, at two points B and C from the front of the ship, fixed relative to point (M). These points B and C are equipped with emitting diodes.
- the distance between these points is the distance l o .
- a maximum distance Imax can be calculated according to three or more travel times. This maximum distance I max is very close to the real distance 1 0 ; thus this arrangement provides the absolute X and Y coordinates of the two points B and C of the bow of the ship and the X and Y coordinates of the point (M).
- the vertical displacement Z is not measured by the camera and, in this case, additional equipment is required.
- Z in this case can be measured by a distance measuring device such as an infrared rangefinder or equivalent device.
- This device continuously monitors the distance from the bow of the ship and the output signal is measured and filtered to give an accurate representation.
- This equipment can be protected against bad weather, in particular, against heavy rain and against substantially vertical reflection from the deck of the ship exposed to the sun.
- a television camera is installed at the end of the arrow (F) and directed at the front of the ship. This arrangement allows the operator to view the operations at the front of the ship and in particular to control the positioning of the articulated arm (L) during this connection.
- This camera is also placed in a waterproof casing and fitted with windscreen wipers.
- this surveillance camera is camera A already installed for measuring the displacement of the bow of the ship.
- Connection monitoring begins once the boat is moored. Before any operation takes place, the movement (Z) of the ship is given by an accelerometer or a “Datawell” type buoy. Statistical analysis decides whether the operation can be carried out or not. In the event that the operation is not to be carried out, the computer interrupts the sequence; if the operation can be carried out, the means available for measuring the movement (Y) is the optical means, which gives the distance separating the arrow (F) from the central axis of the ship and allows the computer to initiate rotation in the arm position.
