1INTRODUCTION
The purpose of this Harbour Acceptance Test (HAT) is to verify that the Echosounders and/or
the ADCPs in the EK80 system are correctly installed, and fully functional. It is then ready for the
Sea Acceptance Test (SAT).
After the HAT, the Customer Acceptance Form must be signed by the relevant parties. The
completed document then becomes the official report. Data logged during the HAT must be
downloaded and stored on KM internal servers for future reference.
1.1 Personnel and location
This Harbour Acceptance Test is done onboard the vessel, alongside the quay. The test is done
by personnel from Kongsberg Maritime, or by a representative from an authorized dealer or
distributor.
The personnel performing the HAT must be qualified operators of the system and have received
proper training.
1.2 Test equipment
The following test equipment is required to perform this test:
•453635 – Shielded dummy load WBT

2HAT PROCEDURE EK80
2.1 Hardware and Software registration
In Table 3 List of Items, fill in the information for all the units supplied by Kongsberg Maritime.
The items supplied can be:
•Computer
•Network switch
•WBTs
•Transducers
2.2 Visual inspection
Perform a visual inspection of all the units in the system. Make sure that they are mounted
properly and do not have any physical damage or scratches.
Also, check that the equipment and the belonging cables are installed according to the
requirements in the installation manual. Check that the units and cables are located so that the
risk of electrical interference is kept at a minimum.
2.3 Test Procedure
To start testing the system, make sure all units are powered on.
2.3.1 Check installation
Open the installation menu in the EK80 software and verify:
•All WBTs and/or ADCP transceivers are installed, including proper licenses
•All transducers installed and connected to the correct transceiver (WBT).
2.3.2 Configuration of interfaces
Verify that all ship interfaces are turned on and operational.
In the Installation -> I/O Setup configure the required inputs and outputs. Configure both the
serial ports and the LAN ports according to the system interconnection and setup
documentation.
As a minimum the following inputs must be set up:
•GPS position
•Heading of the vessel
•Motion data of the vessel
Note! If an ADCP is included in the system, the motion data must be in the KM Binary
format.
Note! If an ADCP is included in the system, it is essential that the ADCP is synchronised to
an available NTP server for accurate timing. The time synchronisation settings can be
checked in the ADCP Editing menu.
Other examples of inputs and outputs may be:

401925 / D / 2021-08-17 / Page 6 of 15
•Transmit synchronisation
•Sound velocity sensor
•NMEA outputs
•…
In the checklist enter OK for the interfaces that are configured and tested OK. For interfaces not
configured enter N/A.
2.3.3 Dimensional survey
A dimensional survey must be present for the HAT to be approved.
Note! The accuracy requirements for the dimensional survey are listed in the EK80
installation manual and the EC150-3C installation manual.
Note! Modest accuracy requirements apply when your EK80 system is only used to
investigate objects in the water column. When used for Acoustic Doppler current
profiler (ADCP) measurements the accuracy requirements are increased.
In the Installation menu, enter the lever arms and angular offsets for all the sensors.
2.3.4 Functional test of Echosounders
Note! Make sure the transducers are in water when pinging is activated. Pinging in air may
damage the transducers. This is especially important to pay notice if the vessel has a
drop keel.
2.3.4.1 Normal operation
Activate one frequency at a time and start pinging. Verify that the echogram looks normal and
that the system detects the bottom at all frequencies.
If EC150-3C is part of the installation, also run this in echosounder mode.
Test the systems with both CW and LFM pulses, where applicable.
If the water is very shallow it might be necessary to reduce the pulse duration and power.
2.3.4.2 Transducer measurements
Measure the impedance and phase for all the echosounder transducers.
Note! This section does not apply to the EC150-3C.
2.3.4.2.1 CW pulses
Make sure all frequencies are set to active and that CW is selected for all. Enter the Diagnostics
-> TRANSDUCER menu. Select one system at a time and verify that the impedances and phase
are according to acceptance criteria.
CW acceptance criteria: 60Ω < |Z| < 95Ωand -30° < φ < 30°.

2.3.4.2.2 LFM pulses
Make sure all frequencies are set to active and that LFM is selected for all transducers where
this is possible. Enter the Diagnostics -> TRANSDUCER menu. Select one system at a time and
verify that the impedances and phase angle plots are as expected.
Verify that the plots look normal, and that there are no large deviations between the different
sectors.
2.3.5 Functional test of ADCP
Note! Make sure the ADCP is in water when pinging is activated. Pinging in air may
damage the transducer.
Configure the EC150-3C to ADCP mode. Set the power and cell size to minimum. Reduce the
colour span of the ADCP to minimum.
Operate the ADCP in both CW and LFM mode.
Verify that you see the bottom return in the echogram and that all beams detect the bottom.
Check if you measure any velocities in the water column.

2.3.6 Noise measurements
To fully utilize the system’s capabilities, it is important to achieve the best possible Signal to
Noise ratio (SNR) for the installation. The first step is to follow the guidelines given in the
installation manual.
For a ship installation, there are other systems and noise sources that inevitably will influence
the SNR, but still, it is important to optimize the installation and keep the influence at a
minimum. KM can provide a report showing the achievable noise levels under ideal conditions.
During the tests, the vessel should have the generators operational and not be running on shore
power. It is important to have the conditions as realistic as possible so that they reflect the
normal operation as close as possible.
Note! Be aware that the lower frequencies can be affected by noise caused by construction
work in the port or background noise in the sea and the surroundings.
2.3.6.1 Setup of system for noise checks
Note! The EC150-3C must be configured in ES mode during the noise measurements.
Set up all the frequencies with the following pulse configurations and settings:
•LFM, passive mode, pulse length 2.048ms, max power, fast ramping
•For frequencies where LFM is not available:
oCW, passive mode, pulse length 1.024ms, max power, fast ramping
•For EC150-3C in ES mode:
oLFM, passive mode, depth cell size 2, max velocity 10m/s, max power
•Echogram range 2000 meters
•Ping mode maximum. Bottom detection should be turned off
•Select TVG to Sv (20 log) and echogram threshold -70 dB
Record data for 5 minutes.
2.3.6.2 Collecting and checking noise data
2.3.6.2.1 Noise data with transducer
Activate all the systems and log data for 5 minutes.
Check the noise estimate value for all the systems in the Diagnostics -> Noise menu. The values
will vary from ping to ping. Do an average over 10 pings and enter the value in the checklist.
2.3.6.2.2 Noise data with dummy load
Note! This section does not apply to the EC150-3C.
Disconnect the transducer cables from all the WBTs and connect the shielded dummy load (P/N
453635). Activate the system(s) with the dummy load connected and log data for 5 minutes.

Check the noise estimate value for all the systems in the Diagnostics -> Noise menu. The values
will vary from ping to ping. Do an average over 10 pings and enter the value in the checklist.
2.3.7 Data download
If no restrictions exist, download the data to an external disk and bring it home for storage on
the KM local server. The data will be used for future reference.
Alternatively, the technical report must include screenshots of installation menus and
echograms for documentation.
