Page 40 A. Transceiver The ME70 and MS70 Transceiver Unit is housed in a 19-inch instrument rack. Easy access to the front and rear of the rack is essential for smooth replacement of parts.
Page 41 The Uninterruptible Power Supply (UPS) must have the capacity to independently maintain power to the ME70 and MS70 systems for a minimum of 10 minutes. This allows you to turn off the ME70 and MS70 systems in a controlled manner in the event of a power failure.
Page 42 Kongsberg ME70 and MS70 Installation Manual G. Steel conduit H. At the bottom of the drop keel, the ME70 and MS70 transducer can be installed with the transducer face flushed with the horizontal plating. The mounting ring is welded to the hole prepared for the transducer. Screws through the clamping ring into the mounting ring secure the transducer in place.
Page 43: Sonar Room Requirements
Make sure that installation or maintenance of other equipment in the sonar room does not affect the ME70 and MS70 system units. The use of heavy tools in the sonar room must be avoided. This includes welding equipment, saws, hammers or similar hand or electrical equipment.
Page 44: Requirements For Watertight Integrity
Kongsberg ME70 and MS70 Installation Manual recommended that you keep the ambient temperature between +5 and +40°C, and the relative humidity less than 80%. The Mean Time Between Failure (MTBF) will increase if these limits are exceeded. Observe the environmental specifications related to each unit.
Page 45: Size And Access Requirements
Preparations Size and access requirements A well designed sonar room with a well fitted size and easy access reduces the risk of corrosion, and simplifies maintenance. This increases system reliability. Note The physical size of the sonar room must be limited, so that in the event of a major leak, the flooding of the room will not induce instability, or cause the vessel to capsize or sink.
Page 46: Requirements For Electrical Installations, Cables And Communication
Kongsberg ME70 and MS70 Installation Manual Insulation requirements The insulation in the sonar room should be the minimum equivalent of 50 mm of rock-wool. Piping passing through the space prone to condensation must be properly insulated. Heating requirements Heating is an effective method for reducing humidity. The heater in the sonar room must be dimensioned to maintain the equipment within its environmental tolerances.
Page 47: Requirements For Bilge Pump And Decking
Proper vessel ground must be provided. Cabling requirements The sonar room units are connected to other ME70 and MS70 units located in different compartments on the vessel. The units may also be connected to peripheral devices. If these cables pass through hatches or areas where they may be damaged, they must be run in conduits.
Page 48 Kongsberg ME70 and MS70 Installation Manual of the compartment, and/or in other locations where the water will gravitate to first. Inspect the bilge sensors periodically. Decking requirement Once the installation has been completed, the sonar room must be suitably decked without restricting access to the equipment and the cables.
Page 49: Where To Install The Transducer
Introduction to transducer position The type of scientific multibeam system determines the position of the transducer. In the ME70 system, the transducer must be installed so that the transducer face points down towards the sea bottom. In the MS70 system, the transducer face must point horizontally to the side.
Page 50: Flow Noise
At that depth, the water is free of air bubbles up, even during very high sea states. At the bottom of the drop keel, the ME70 and MS70 transducer can be installed with the transducer face flushed with the horizontal plating.
Page 51: Avoid Protruding Objects Near The Transducer
Preparations Related topics Installation summary on page 33 Installation principles on page 37 Where to install the transducer on page 47 Preparations on page 33 Sonar room requirements on page 41 Avoid protruding objects near the transducer Objects protruding from the hull will generate turbulence and flow noise. This will reduce the overall performance of your system.
Page 52: Keep The Transducer Far Away From The Propellers
Kongsberg ME70 and MS70 Installation Manual A. Turbulent flow B. Laminar flow C. Air bubbles Air bubbles absorb and reflect the sound energy, and they may in worst cases block the sound transmission altogether. The boundary layer increases in thickness when it becomes turbulent. The boundary layer is thin in the forward part of the vessel hull, and increases as it moves aft.
Page 53: Mount The Transducer At A Safe Distance From Bow Thruster(S)
When in operation, the noise and cavitation bubbles created by the thruster may make your ME70 and MS70 transducer useless, almost no matter where it is installed. When the bow thrusters are not in operation, the tunnel creates turbulence. If your vessel is pitching, the tunnel may be filled with air or aerated water in the upper position and release this in the lower position.
Page 54: Summary And General Recommendations
Kongsberg ME70 and MS70 Installation Manual Summary and general recommendations Some of the installation guidelines provided for transducer location may be conflicting. For this reason, each vessel must be treated individually in order to find the best compromise. In general, the most important factor is to avoid air bubbles in front of the transducer face.
Page 55: Acoustic Noise
Preparations Acoustic noise As with any other hydroacoustic systems, the quality of the ME70 and MS70 echo data and presentations are subject to unwanted acoustic noise. The echoes from any large and small target must be detected inside the noise.
Page 56 Kongsberg ME70 and MS70 Installation Manual during operation. As for the target properties, there is nothing any of us can do with those. The signal-to-noise ratio, however, can be improved by making the correct choices during installation. Signal-to-noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise.
Page 57: Self Noise
Preparations • Propeller noise • Flow noise • Acoustic noise from other hydroacoustic systems B. The transducer cable is long. Electric noise from generators, pumps, cooling systems and other electric or electromechanical devices is easily picked up. C. The preamplifiers are very sensitive. They can easily pick up electrical noise from internal and external power supplies.
Page 58: Propeller Noise
Kongsberg ME70 and MS70 Installation Manual International regulations and certifications are used to control and reduce this, but even these are limited if the electrical systems are poorly installed and/or maintained. Propeller noise Propeller noise is often the main source of noise at higher vessel speeds. Variable pitch propellers or fast moving propellers usually make more noise than fixed propellers or slow moving propellers.
Page 59 Preparations Turbulent flow Laminar flow Air bubbles Air bubbles absorb and reflect the sound energy, and they may in worst cases block the sound transmission altogether. The boundary layer increases in thickness when it becomes turbulent. The boundary layer is thin in the forward part of the vessel hull, and increases as it moves aft. The thickness depends on ships speed and on the roughness of the hull.

Page 62 Kongsberg ME70 and MS70 Installation Manual Reducing flow noise The shape of the transducer (or dome around it) must be as streamlined as possible. The hull plating in front of the transducer must be as smooth as possible. Important: Be especially aware of bilge keels and sacrificial anodes.
Page 63: Reducing Electrical Noise
(for example the K-Sync) should be considered. Reducing electrical noise These points must all be considered to reduce electrical noise in the ME70 and MS70 systems. • Place the transducer cables in a metal conduit all the way from the transducer to the transceiver.
Page 64: Installing The Transducer
Transducer description The Kongsberg ME70 and MS70 transducer is a short cylindrical container with 800 transducer elements. The transducer elements are located at the "bottom" of the transducer. When the transducer is mounted, the elements are facing down towards the seabed.The transducer cables are provided as 25 individual cables in three bundles.
Page 65 A mounting ring must be welded to the lower blister plate. A clamping ring is then inserted from the bottom and up. The transducer is secured with twelve -12- M12 bolts through the clamping ring, and fastened to the mounting ring. Both rings may be supplied with the ME70 and MS70 system delivery. Note An accurate measurement of the final position and angular orientation of the transducer is always required after installation.
Page 66: Sacrificial Anodes
Kongsberg ME70 and MS70 Installation Manual Sacrificial anodes The transducer is provided with three sacrificial zinc anodes. These are mounted on its top surface (lid). The sacrificial anodes must be replaced when 1/3 of their bodies have been spent. If it is difficult to access the zinc anodes after the transducer has been installed, additional anodes must be mounted inside the blister.
Page 67 Installing the transducer Rules for transducer handling Observe these transducer handling rules: • Do not activate the transducer when it is out of the water. • Do not expose the transducer to direct sunlight or excessive heat. • Do not use high-pressure water, sandblasting, metal tools or strong solvents to clean the transducer face.
Page 68: Transducer Installation Principles
It can also be mounted using a suitable hole in the hull plating. If your vessel is fitted with a drop keel, this is a superior platform for the ME70 and MS70 transducer. Drop keels are often used on larger research vessels. A drop keel will frequently protrude as far as three meters below the hull.
Page 69 A typical streamlined blister is shown as an example. A common blister can be used to contain both the ME70 and MS70 transducer as well as transducers for other acoustic systems. If many acoustic systems are used simultaneously, due care must be taken to prevent acoustic interference between the different instruments.
Page 70: Using A Drop Keel
Kongsberg ME70 and MS70 Installation Manual Using a drop keel A drop keel is a superior platform for the ME70 and MS70 transducer. Drop keels are often used on larger research vessels. A drop keel will frequently protrude as far as three meters below the hull.
Page 71 Installing the transducer Provide enough slack for maintenance and replacement purposes. Minimum two meters of cable must always be available for installation inside the Transceiver Unit. Once the transducer is positioned, the transducer cables - with the transceiver plugs - must be pulled through the steel conduit.
Page 72: Inclination Angle
As an option, Kongsberg can provide the transducer with each cable in a protective hose. These hoses start inside the transducer. Protection can be used along the entire length of the cables, and all the way up to where the cables penetrate the bulkhead to where the transceiver is installed.
Page 73 Installing the transducer Note The protective is hose is fitted to the transducer cables during the production. For this reason, the length of the hose must be specified when you order the transducer. The transducer cable must be properly fastened at the bottom of the drop keel. They must be fully supported while lowering and hoisting the drop keel.

During this test, noise measurements are done for different vessel speeds. The weather and sea conditions for the noise measurements will be those at the time of the test.
Page 216 Kongsberg ME70 and MS70 Installation Manual • The water must be as deep as possible. • There must be no other vessels in the vicinity. • The vessel must lie still in the water. • As much machinery as possible must be turned off. It is particularly important to turn off electrical motors, as well as cooling systems and hydraulic pumps that may cause electric noise.
Page 217 Setting to work If possible, verify the vessel speed on the top bar. In the Numerical view, read the noise level estimates for the centre beam (beam 3) and from one of the outer beams (beam 0). Record the values in the result table. In the Echogram view, for the centre beam (beam 3) and for one of the outer beams (beam 0), estimate the range to where the noise becomes visible.
