1 SYSTEM DESCRIPTION

1.1 Overview

The Kongsberg Simrad EM 1002 multibeam echo sounder is designed for high resolution seabed mapping from the shoreline and down to a depth of approximately 1000m. The system is easy to install, even on small vessels. The EM 1002 has an accuracy surpassing the IHO standard, including the most stringent of the latest version, 4th edition.

The EM 1002 uses the same transduceras theprevious EM 1000, but new and more compact electronics and newsoftware allows a higher pingrate, almost twice the number of beams per ping with narrower beamwidth, higher accuracy, and a much improved operator interface.

The EM 1002 system has a maximum ping rate of more than 10 Hz, a large number of measurements per ping with 111beams, 2° beamwidth, and electronic roll stabilization. Mechanical pitch compensation is available with an optional hull unit. Acrosstrack coverage is up to about 1200 m in deeper waters, and in shallow waters up to 10 times depth beneath the transducer. The angular coverage isfully adjustable, and for surveying to the watersurface alongshorelines, riverbanks andman-madestructures,theangular coverage to one or both sides may be increased to 5° above the horizontal.

The standard EM 1002 system has three different pulselengths (0.2, 0.7 and 2 ms) to maximize coverage in deeper waters, say more than 200 m.A shallowwater version, the EM 1002S, which is identical to the standard system except for having only the shortest pulselength, isa cost-effective alternative to users who do not need the deep water capability. The EM 1002S is usable to more than 600 m water depth, but acrosstrack coverage is limited to about 1000 m and will typically be less than half that of the standard EM 1002 for depths larger than 300 m. The EM 1002S may be upgraded to an EM 1002 if required.

The system’s nominal sonar frequency is 95 kHz. This frequency allows for small dimensions, good range capability and high tolerance to turbid waters. Integrated seabed acoustical imaging capability (sidescan) is included as standard. A combination of phase and amplitude detection is used, resulting in a measurement accuracy practically independent of beam pointing angle.

EM 1002 / Base version

850-160977/E

The EM 1002 is a complete system with all necessary sensor interfaces, real-time compensation for vessel motion and raybending, data displays for quality control including sensor calibration, and data logging included as standard.

Postprocessing software is available for both for bathymetry and seabed classification. A worldwide marketing and service organization having many years of multibeam experience is available for supporting the EM 1002

1.2 System units

Overview

TheKongsberg SimradEM1002 multibeamechosounder consists of these main units:

· Transducer Array

· Transceiver Unit

· Operator Station

· Hull Unit (optional)

® The EM 1002 system units are shown on page 3. ® The EM 1002 hull unit system units are shown on page 4.

Transducer array

The EM 1002 Transducer Array is used both for transmit and receive. It issemicircular witha radius of 45 cm and 160° angular extent and its weight in water is about 90 kg. Eight 20 m long underwater cables connect the transducer to the T ransceiverUnit. The cables are fitted with connectors on the dry-end side, these plug in on the Transceiver Unit.

Transceiver Unit

The EM 1002 Transceiver Unit contains the transmit and receive electronics and processors for beamforming, bottom detection, and control of all parameters with respect to gain, ping rate and transmitangles. It has serialinterfacesfor all time-criticalexternal sensors such as vessel attitude (roll, pitch, heading and heave), vessel position, and external clock.The Transceiver Unit isa wall mounted cabinet with integrated shock and vibration absorbers. An Ethernet cable connects the Transceiver Unit to the Operator Station.

Operator Station

The Operator Station is a high-performance workstation. It contains the operator interface, displays the collected data, and logs them to disk and tape.

Hull Unit

The EM 1002 Hull Unit isa electromechanical device designed to physically lower thetransducer array from a safe storageposition down into the water. The array may be lowered to a maximum depth of 82 centimeters under its storage position within the hull.

The HullUnit will alsomechanically stabilize the transducerarray tocompensate for the vessel’spitch movements during the survey.

2 OPERATIONAL PROCEDURES

2.1 Introduction

This chapter presents the most important operational procedures required to operate the Kongsberg Simrad EM 1002 multibeam echo sounder.

The EM 1002 is operated in on-line or off-line mode.

· The on-line mode is used during the survey. The applications

arethen usedto controlthe multibeamecho sounder, tostorethe data, and to present various views of the data for quality assurance. The on-line applications are started from the EM 1002 Launchpad.

· The off-line mode is used after thesurvey has been completed,

and the data is stored on disk or tape. The applications are then used to view the results of the survey.

The standard EM 1002 applications will generate a full documentation of the survey results, and will provide output for survey statistics, contour charts, illuminated plots etc. For some purposes this may be sufficient, but normally thepost-processing packages available are used for data cleaning, image processing and final chart production.

The following main operational functions are described in this chapter:

® Starting the EM 1002 system: page 8 ® Preparing the system for use: page 9 ® Running a survey: page 18 ® Closing down the EM 1002 system: page 22

This chapter also presents a general description of the desktop operational environment, and - in addition - thefollowing special subjects are described:

® Main Survey Display functions: page 55 ® System selftest: page 62

Operational procedures for the various additional utilities are not found in this chapter. Refer to the applicable utility descriptions further back in the book.

Welcome to [host name]

1 Enter your user name: em1002 2 Press <Enter>.

When this log-in is completed, the system presents the EM 1002 log-in dialogue box:

Welcome em1002

3 Enter your password: simrad0 4 Press <Enter>.

- The system initiates the Common Desktop Environment (CDE), and the following information is

presented:

· Icon dialogue box

· Common Desktop Environment (CDE) dialogue box

- These dialogue boxes are all standard applications provided with the Unix operating system.

- You are now ready to start the EM 1002 software.

5 Placethe cursor in thebackgroundpart of the display image. 6 Press the middle

mouse button.

- A small menu is displayed on the screen. This menu allows you to start the on-line applications (EM 1002) and/or the off-line applications, such as Merlin or Neptune.

7 Select Start Operator Interface on the menu.

- The following applications and dialogue boxes are automatically started:

· Launchpad

· Ping Display

· Runtime Menu

· Survey Display

- Note that the dialogue boxes appear in different workspaces. You can select either one of these on the Launchpad, or in the CDE dialogue box.

Launchpad introduction

The EM 1002 Launchpad is the control dialogue box for the EM 1002 on-line operations. This utility provides realtime monitoring of the storage capacity, sounder parameters and sensor status. It also contains buttons to start and stop the echo sounder and the logging, as well as controls to select the active workspace. The icons are used to activate the other applications provided for the EM 1002 on-line operations, while the bottom field identifies the operator and the current survey.

® The EM 1002 Launchpad is described in detail on page 65.

2.4 Planning and calibration

Survey plan

As a general rule, the survey shouldbe properly planned. The plan can be based upon a chart where the planned survey lines are plotted. General knowledge about the bottom conditions may be useful.

® Survey planning is described in more detail on page 60.

When the EM 1002 systemwas installed, the physical locations of sensors and peripherals were defined, and the appropriate settings were made to the EM 1002. These settings include:

If any of thesesettings have changed,the system parameters must be adjusted accordingly before the survey starts.

® This hardware set-up is described on page 24.

Calibration

To ensure maximum reliability and accuracy from the system, the EM 1002 and externally connected sensors should be calibrated before the start of a new survey.

® A calibration procedure is described on page 254.
