Page 19: Inspecting And Cleaning The Transducer Face
Transducer handling and maintenance Inspecting and cleaning the transducer face Marine growth (biological fouling) on the transducer face reduces the ES18 performance. For this reason, it is important to keep the transducer face clean. Every time your vessel is in dry dock, you must remove the marine growth. At the same time, you must inspect the transducer closely for physical damage. -
Page 20: Painting The Transducer Face
Check for dents, scratches, holes or other damage to the surface. If you find suspicious damage, take high resolution photos that show the damage. Contact your dealer or the Simrad support organization for advice. If necessary, apply anti-fouling paint as described in the dedicated procedure. - Page 21 Transducer handling and maintenance • Airless spray Because some paint types may be aggressive to the polyurethane in the transducer, consult our list of approved paints. Context The transducer has not been designed with any protection against biological fouling. Anti-fouling paint may therefore be applied to the transducer face. To minimize the negative acoustical effects the layer of anti-fouling paint must be as thin as possible.

Page 57: Transducer Installation Inside The Hull
Transducer installation principles Transducer installation inside the hull The transducer can be mounted inside the hull. This installation method forces the transducer to send and receive the acoustic pulses through the hull plating. This requires a good acoustic contact between the transducer face and the hull. In order to install the transducer like this, you must design and build a tank around the transducer. -

Page 61: Using A Suitable Inclination Angle
Transducer installation principles Using a suitable inclination angle Ideally, the transducer face should be mounted in parallel with the sea surface when the vessel is in normal trim, as this will provide the most accurate echo information. However, it is also very important that the water flow over the transducer face is laminar. In order to ensure laminar flow, the transducer face must be tilted slightly upwards in relation to the water flow. - Page 62 Simrad ES18 Installation Manual Emuge’s saw-tooth profile up to pitch P ≤ 0.7 mm Emuge’s saw-tooth profile up to pitch P >0.7 mm Standard thread External thread Internal thread The advantages of using Emuge self-lock thread include: • The thread locking feature if integrated in the internal thread •...

Page 66: Introduction To Transducer Location
Simrad ES18 Installation Manual Introduction to transducer location A single answer to the question "where to install the transducer" cannot be given. The physical location of the transducer depends on the vessel's design and construction, how the hull is shaped, and how the water runs along the hull. There are however a number of important guidelines, and some of these are even conflicting. -
Page 67: Avoid Protruding Objects Near The Transducer
Where to install the transducer Slamming Slamming happens if the vessel hull climbs out of the water in heavy seas. The force of the water when the hull falls down may push the transducer up, and may cause damage both to the transducer and to its mounting. This is especially important for low frequency transducers with large faces. -
Page 68: Mount The Transducer At Forward Part Of Hull To Minimize The Effects From The Flow Boundary Water Layer
Simrad ES18 Installation Manual Mount the transducer at forward part of hull to minimize the effects from the flow boundary water layer The upper water layers of the sea contain a myriad of small air bubbles created by the breaking waves. When the hull moves through water it will cause a disturbance, and this will generate friction. -
Page 69: Keep The Transducer Far Away From The Propellers
Where to install the transducer Keep the transducer far away from the propellers The propulsion propellers is the dominant noise source on most vessels. The noise is easily transmitted through the water. This noise may often reduce the overall performance of your ES18. The transducer must be installed as far away from the propellers as possible. -
Page 70: Summary And General Recommendations
Simrad ES18 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 71 Where to install the transducer If the vessel hull has a bulbous bow, this may well be a good transducer location, but also in this case the flow pattern of the aerated water must be taken into consideration. The foremost part of the bulb is often a good location. Thruster Transducer location This applies to the vessel in normal trim and speed.
