1 - Hydroacoustic Position Reference System consists of transducer(s) onboard a vessel communicating with transponder(s) placed on the seabed. The transducers are lowered beneath the hull, and when a transponder is deployed on the seabed, the transducers can start interrogating. The transponder is listening for the interrogation and it answers with its own frequency. The transducer receives the answer and is able to determine range and direction to the transponder. This defines the vessel position with reference to the seabed transponder and this information is fed to the dynamic positioning system. Jan Kongsberg Maritime AS Page Rev. 07 Training
2 Sound in Water Various physical laws influence the signals travelling through water. The strength of the signal, the direction from where it comes, and noise conditions are examples. The speed of sound in sea water is approximately 1500 m/s. The sound waves will decrease in power when they travel through water and the path from the surface to the seabed will depend on salinity and temperature layers. Page Kongsberg Maritime AS Jan Training Rev. 07
3 Ray bending When the velocity increases from the surface to the bottom (higher salinity and/or temperature), the signal path will be bent up. When the velocity decreases from the surface to the bottom (lower salinity and/or temperature), the signal path will be bent down. Lower velocity Higher velocity Higher velocity Lower Higher velocity velocity Without information about sound velocity in the system, the transponder position will be calculated along the dotted lines. Sound profile Below is an example of a profile. On the picture to the left you can see the profile. The velocity increases quickly from the surface down to m. This sudden change is also found on the ray trace picture to the right.

If you received a reply from a transponder using the above example, it would be a signal bounce, where the pulse would be going between the seabed and surface one or more times. The mean sound velocity is used to calculate the range, while the transducer sound velocity is used to calculate the angles to the transponder. Jan Kongsberg Maritime AS Page Rev. 07 Training
4 Signal Loss The signal strength is reduced as a function of distance and frequency. db Transmission loss Transmission loss in db Alpha 1.5 db/km - 13kHz, 5dB - 25kHz, 8dB/km - 32kHz Range TL 13 khz TL 25 khz TL 32 khz From the table can be seen that low frequencies have less loss than higher, and should work at longer range. The size of the transducer is determined by the frequency. To have low frequency transducers with the same requirements as medium frequency transducers regarding opening angles, requires bigger physical size. Noise The factor that causes most problems is noise. Noise can be generated from the vessel itself (motors, thrusters etc.), from neighbouring installations or vessels, ROVs or from the waves. SPECTRUM LEVEL (DB RE 1UPA) THRUSTER NOISE 100 DRILLING NOISE 80 SHIP NOISE WIND FORCE BEAUFORT (CD3942) FREQUENCY HZ ENVIRONMENTAL ACOUSTIC NOISE LEVEL The diagram shows different types of noise with frequency and noise level. Page Kongsberg Maritime AS Jan Training Rev. 07
5 The curves indicate clearly that thruster noise is far the strongest. Thrusters generate noise, but they can also make air bubbles in the water, and if these come between the transducer and the transponder, the signal can be blocked. Going astern with the vessel using the main propellers normally pulls a lot of air under the hull, this might cause signal blockage similar to that caused by the thrusters. Operational Principles - LBL / SBL / SSBL Jan Kongsberg Maritime AS Page Rev. 07 Training
6 SSBL Principle (Super Short Base Line) When using the SSBL principle, the distances between the elements inside the transducer (base lines) are used to calculate the transponder position. The position calculation is based on distance and direction measurements to one transponder. An interrogation pulse is transmitted from the onboard transducer, which will interrogate the subsea transponder, which again will answer with a reply pulse. If the transponder on the seabed is slightly out of vertical line, there will be a small time difference from one element to the other when the pulse hits the surface of the transducer. This time difference is extremely small and hard to measure by a clock. Instead the system measures the phase difference when the signal hits for instance the Ref. and Y element in the drawing below. When we know the wavelength, and the phase difference, the time difference can be easily calculated. With this information we can calculate the angle of the reply pulse and determine from which direction the pulse is coming. When we know the speed of sound in water we can find the distance. Angle measurement Computation of position in the forward/aft direction Computation of position in two planes Page Kongsberg Maritime AS Jan Training Rev. 07
7 LBL Principle (Long Base Line) The LBL system consists of one transducer and an array of transponders, where the exact distance between each transponder is known. The base lines are no longer the elements inside the transducer, but the distance between the transponders. For SSBL the base lines are less than 10 cm, while for LBL the base lines can be more than 1000 m. The distances between the transponders are calibrated, and LBL is therefore more timeconsuming to set up than SSBL. The calibration is done using a built-in mode in the transponders. All the transponders will be interrogated simultaneously, and they will respond with their individual replies. The LBL system will calculate the ranges from the individual transponders, and by using the base lengths of the calibrated transponder array together with these ranges in software algorithms, the vessel can be positioned. The advantage of LBL systems over SSBL systems is that accuracy is maintained down to decimetre level, even if the ranges are several hundred meters. The transducer might be an SSBL type, or it can be a special one with only one element, since angular measurements are not used. LBL requires intelligent transponders that can be commanded to execute different operations using telemetry. Jan Kongsberg Maritime AS Page Rev. 07 Training
8 Transducers and transducer elements A transducer is an acoustic transmitter/receiver normally placed onboard the vessel, approximately 3 m below the keel. Mounted on a pole which is remotely operated from the bridge, it can be lowered or recovered whenever necessary. A transducer consists of several transducer elements. Electric connection Steel block Electric connection 2 blocks of ceramic crystals Magnesium block Rubber cover Transducer face The elements will start vibrating when voltage is applied, transmitting sound waves with correct frequency. When the pulses from the transponder are received, the elements start generating voltage. The internal distances between these elements are known. Page Kongsberg Maritime AS Jan Training Rev. 07
9 Typical System Overview - HiPAP transducer There are different systems and transducers on the market. Kongsberg Maritime is well known for the efficient HiPAP transducer, (High Precision Acoustic Positioning). The HiPAP hull unit uses the same relay unit to lower and hoist as the two other hull units. The transceiver is installed close to the hull unit, since the cable from the hull unit to the transceiver is only 5 m. Position data is sent from the operator unit to other equipment. The digital interface can be RS232, RS422, current All interfaces to the transceiver (gyro and VRU) are in serial format (RS422) loop or ethernet. Jan Kongsberg Maritime AS Page Rev. 07 Training
10 Transponders A transponder is an acoustic receiver/transmitter placed on the seabed or onboard an ROV or any other structure to be positioned. It is triggered from the vessel using acoustic signals, and will in normal operation only answer if it is interrogated from the vessel. The power source is normally a battery, the lifetime of which depends on how often the transponder is interrogated and what kind of battery type is used. The size and weight of the transponders are determined by the depth specification and battery lifetime. Page Kongsberg Maritime AS Jan Training Rev. 07
11 RPT type For 1000 m depth rated transponders an aluminium housing is chosen. The RPT type is a combined transponder/responder, which can use an external DC power source in addition to internal battery. For 3000 m depth rated transponders a stainless steel housing is chosen Transponder Deployment When deploying the transponder it is important to prevent the air produced by main propellers, thrusters, diving bell, etc. from obstructing the path of communication between the transponder and the transducer. When the system is part of a dynamic positioning system the current and wind direction must be considered before deploying the transponder. The transponder must be deployed in a position where the current carries the air from a diving bell or other air producing equipment away from the operating area. Jan Kongsberg Maritime AS Page Rev. 07 Training
12 The transponders might be deployed with a rope or a wire going to a buoy or the vessel on the surface, or they might be "thrown" over the side of the vessel if they have an acoustic release mechanism. The length of the rope between the transponder base and the weight can be 2-5 m. The recommended weight of the sinker is different for 1000 m and 3000 m transponders. For 1000m transponders we recommend a weight of approx. 60 kg. For 3000m transponders we recommend 100 kg. Keep in mind the current when transponders are deployed. The weight might be increased if the current is strong, it is most important to get the transponder in the exact predetermined position. REMEMBER: Make sure the weight of the transponder and the sinker is brought up in the sinker and NOT in the protective cage on the transponder whenever the transponder is handled. The cage is for protection of the transducer, and is certified for lifting the transponder with flotation collar only. Page Kongsberg Maritime AS Jan Training Rev. 07
13 Transponder models We have three main groups of transponders: - MPT Multifunction Positioning Transponder - SPT SSBL Positioning Transponder - RPT ROV Positioning Transponder MPT transponders are used in: SPT transponders are used in: RPT transponders are used in: LBL positioning Array calibration SSBL positioning General telemetry commands *) SSBL positioning General telemetry commands *) ROV positioning Tow-fish positioning (The RPT does not have the telemetry option) The transponder model name gives the user information about operating frequency, depth rating, transducer beam width and any option. The transponder name is put together like this: Model name: Transponder name = model name + model number + options - MPT = Multifunction Positioning Transponder - SPT = SSBL Positioning Transponder - RPT = ROV Positioning Transponder Model number: 1. digit 2. digit 3. digit 1=15 khz (low frequency) 1=1000 metre depth 1= ±15 beam width 3=30 khz (medium frequency) 2=2000 metre depth 3= ±30 beam width 3=3000 metre depth 4= ±45 beam width 6= ±60 beam width 9= ±90 beam width Some of the options available: - D = Depth sensor - H = Heading magnetic compass - E = External power - I = Inclinometer - II = Internal and external inclinometers, (diff.inclo. TP) - N = Rechargeable NiCAD or seal lead battery pack - R = Release mechanism - S = Split, separate transducer and housing - T = Temperature sensor - Rsp = Responder - DuB = Dual Beam Jan Kongsberg Maritime AS Page Rev. 07 Training
