Universitetet i Bergen (UiB) anskaffet i 2001 et marint streamer system som bestod av:

  • TriAcq recording system
  • Nessie-3 (N3) digital streamer, 3 km, 240 kanaler

Fra før hadde UiB andre deler som trengtes:

  • Geco airgun controller, GUNCO (1990)
  • Streamer "birds" (for vertikalkontroll av streamer) - DigiCourse mod. 3010

Systemet skal nå overføres til Universitetet i Tromsø, for bruk på FF "Kronprins Haakon"

SPARCserver 1000E - boot problem, januar 2021


  • Sun SPARCserver 1000E skal starte operativsystemet (Sun Solaris) fra det eksterne SCSI disk kabinettet.
  • Det har tidligere vært problem med oppstart, som er blitt løst ved enten å trekke ut og sette tilbake SCSI konnektor i SPARCserver'n, eller justere avlastningen (en snor som holder konnektoren fiksert i 90 graders vinkel ut fra maskinen - slik at pins i konnektor ikke har noe vinkel-moment på seg).
  • Får heller ikke frem diagnostikk-meny (POST = "Power-Up Self-Test", se link til manual i avsnitt over) der man kan undersøke responsene fra enheter på SCSI-bussen.

Mulige løsninger


  1. Booting and Testing Your System -- "This chapter describes the most common tasks that you perform using the OpenBoot firmware. "
  2. ''Frequently Asked Questions about Sun NVRAM/hostid:
    • " ... The sun4d machines (e.g. SS1000) also have an NVRAM chip. However, the IDPROM information ..." --- "sun4d" is a certain Sun machine architecture. "It is a development of the earlier Sun-4 architecture, using the XDBus system bus, SuperSPARC] processors, and [[https://en.wikipedia.org/wiki/SBus | SBus I/O cards. The XDBus was the result of a collaboration between Sun and Xerox; its name comes from an earlier Xerox project, the Xerox Dragon. These were Sun's largest machines to date, and their first attempt at making a mainframe-class server."

Nessie-3 (N3) main features


Streamer, N3:

  • Fabrikant: Western-Geco
  • Modell: "Nessie-3" (N3)
  • Antall kanaler (traser): 240
  • Antall aktive seksjoner i streameren: 30 stk
  • Lengde hver aktiv seksjon: 100 m
  • Gruppelengde (Hydrophone group spacing): 12.5 m (normal konfigurasjon; 6.25 m also possible)
  • Groups/section: 8
  • Digitaliseringsenhet ("bubble"):
    • En stk for hver 2. aktive seksjon
    • Altså 15 stk
    • De innerste enhetene fjernes når streamer'n skal lagres (pga liten spolediameter på de innerste lagene).

TriAcq system:

  • Digitizing in-sea, one digitizing unit (nicknamed 'bubble') every 2nd section.
  • Compact bubble; diameter same as streamer diameter.
  • Applies digital production filters.
  • 1008 maximum channels per streamer, up to 16 streamers with maximum channel capacity of 6500.
  • 1 ms to 4 ms sample rate.
  • 6.25 m and 12.5 m hydrophone group spacing.
  • 6.25 m group consists of 12 hydrophones; 12.5 m by wiring two 6.25 m groups in parallel.
  • Spare transmission channels for increased reliability.
  • Low system noise (100dB dynamic range).

N3 oppbygging


A streamer is composed of several different pieces - stretches, active sections, bubbles, repeater bubbles, tail-buoy tow cable. Every second active section is followed by a bubble. Hydrophone groups overlap between sections, hence, at the front of the actives we use a 10m half group section (the last active at the tail has a redundant half group).

Streamer section nomenclature


All Western-Geco streamer sections have their own unique identification code and serial number. The code consists of letters, and indicates the function and hardware arrangement of the section.

Ulmatec Baro (formerly Baro Mek. Verksted) has been shown pictures above. Their reply (2014):

"We can not confirm the winch was manufactured by Baro. It might look like a Baro winch, but details differ. The hydraulic motor is also unknown to us. It might look like a Geco winch from the 1980'ties. The slip ring unit is similar to the types that Geco used. Baro did not deliver winches to Geco. Odim is a possible supplier. It might also be a copy made in USA or UK."

29 May 2017, measured on winch, in Longyearbyen (storage facility, contact LNS Spitsbergen):
Frame is 3,92 x 2,45 m, drum approx Ø 3m, hydraulic motor protrudes 0,95 m from drum, and distance from center of hydraulic motor to ground is 1,55 m.

Krav til hydraulikk / tiloplinger


Ulmatec Baro AS recommends the following (2014):

"When your winch was delivered, the usual hydraulic pressure was 175 Bar. In later years there has been a tendency for increased pressure; nowadays 220-230 Bar is common. Pressure can be reduced in proper hydraulic component ("Trykket kan reduseres i manøverventil ...") in order to use the old winch. Flow rate should be 100-200 liter/minute depending on winch cable force and rotating speed. Hydraulic pump must also be dimensioned according to the number of motors that must be operated simultaneously."

No. 5 has crossfeed from the solenoid pulse; the "crosfree blanking" feature of the GUNCO is activated (red area), causing any signal that appears within the read zones to be ignored.

GUNCO connector wiring


The key to understand the GUNCO connector system is to see how the front slot positions of the MSIBG cards corresponds to the connectors on the rear side - see figure below.

We normally only use one MSIBG card located in slot #5. This card will thus have sensors connected on SI3 (labelled "STBD1,2"), and solenoids on SO5 (labelled "STBD 1").

The difference is that relays have been added for the airgun solenoid test unit, which allows the operator to monitor sensor voltage and current, and measure resistance to solenoid.


SYNC UNIT - INTERFACE TO EIVA SURVEY COMPUTER


The Sync Unit is placed between the EIVA Survey computer and GUNCO. It receives a trigger command from the survey computer in the form of an ASCII "A" sent over RS232 serial line.

The Sync Unit was designed in 1998 and at that time also interfaced two other systems, a magnetometer and a recording system (DFS V) that have both been phased out long time ago. The LCD menu hasn't been updated and thus still provides options that reflects those now unused systems (so don't get confused).

At that time the Survey Computer by mistake sometimes issued double shot event triggers a couple of seconds after the proper trigger. This caused the GUNCO to fire when it wasn't supposed to. To prevent this situation the Sync Unit was furnished with a software timer that defined a period in which new triggers were ignored after the first one. The green LED on the front panel is lit during this "trigger ignored" interval.

This survey requires 12.5 meter shot point distance, which means the "trigger ignored" setting must be reduced from it's current value of approx 8 seconds, down to 1 second. This is explained in section below.

Routing of CLOSURE and FIRE signal to GUNCO


The GUNCO is now controlled by the "Triacq" recording system of the 3km streamer. Two BNC cables must be relocated so it will become slave to the Sync Unit instead:

  1. Disconnect the coax cable bundle (consisting of three cables) from the Triacq recording system. The Triacq recording is located in rack #3 counting from GUNCO. Remove the rear wooden "door" in the corridor.
  2. Route like this:
      ---------------------------
      SYNC UNIT           GUNCO
      ---------------------------
       CLOSURE   <---->   CLOSURE
       FIRE      <---->   FIRE
                          FTB  (not needed)

Schematics


CPU card inside: "Flashlite-V25"


The CPU card is "Flashlite-V25" made by JK Micro. This product has long since been replaced by other versions. The documentation cannot be located (here's a report from someone using it in 2000). But it's quite similar to its replacement, Flashlite 186:

Flashlite 186 embedded computer made by JK Microsystem
Flashlite 186 embedded computer made by JK Microsystem.

How to alter the "trigger ignored" time parameter


The Flashlite 186 CPU card is in reality a tiny MSDOS computer. In initial mode we get contact with the card via serial RS232 cable. A terminal program will then get access to the normal DOS prompt.

A user program is automatically started by following instructions found on page 2 of the Flashlite 186 manual:

When power is applied to the Flashlite or when it is reset, the board goes through its initialization procedure and then starts DOS. A simple (read-only) AUTOEXEC.BAT file is executed and then the board is ready to use. The batch file performs several functions before the user is given control. The DOS search path is set, the DOS prompt is set, the CTRL-C flag (discussed later in this manual) is checked and finally, an attempt is made to execute a file named STARTUP on the B: drive. This provides a convenient way for custom applications to execute immediately after initialization of the Flashlite. If you wish to have your application start automatically, create a batch file named STARTUP.BAT that invokes the program.

Here is the crucial point. The program accepts command line parameters. The first parameter instructs the card to operate in either "OBS" mode (that we use now) or "DFS" mode (which is deprecated). And the second parameter sets the "trigger ignored" duration, in seconds.

So in the STARTUP.BAT file the last line will be the program name followed by two parameters, "OBS" and "8" (or close to that figure). The last parameter must be set to "1" instead. If it's omitted the program uses a default value of 15 seconds instead.

How can the STARTUP.BAT file be edited? First the program that is running on the CPU card must be terminated or prevented from starting. That can be done in two ways:

  1. Connect a RS232 serial cable (1-to-1) between laptop and 25-pin female DSUB connector at the rear of the Sync Unit. Start a terminal program on laptop (TeraTerm or HyperTerm). Comm parameters are: 9600 8N1. This is what is referred to as the CONSOLE input in the Flashlite manual.
  2. Prevent the program from starting by entering <CTRL>+<C> after resetting or powering the unit (there is a reset switch on the top, or use the rear rocker switch). After interrupting the normal start-up sequence the CONSOLE port should now issue a DOS prompt.
  3. ALTERNATIVELY: Quit a running program by sending a <Q> or <ESC> character. Important: This command must be sent on the other serial port - the one that is connected to the Eiva Survey Computer and normally only receives the trigger character <A>. After that switch to the CONSOLE serial port. Press <ENTER> to see that DOS prompt is returned. This port is 25-pin DSUB male. It is probably wired as DTE (Data Terminal Equipment) with output on pin 2 (which will be pin 3 if measured on a 25-to-9 pin adapter). So a null modem cable or -adapter is needed.

The edit process itself is described on page 15 of the Flashlite 186 manual:

EDIT.COM
A simple line editor is included to allow quick creation and modification of batch files or other text files. EDIT is similar to Microsoft’s EDLIN provided in earlier versions of MS-DOS. It allows list, insert, delete, and modify. Upon exit, a backup of the original file is created (filename.BAK) and the edits are saved. If a backup file with the same name already exists, it is overwritten. A list of commands and their usage is available by entering ‘h’ at the edit prompt ( >> ). The name of the file to edit must be supplied following the command EDIT on the command line.

 EXAMPLE:
  B:\>edit test.bat
  FlashLite Line Editor v1.0
  Enter h for help
  New File: test.bat
  >> i
  0: @echo Batch file being processed...
  1: mytsr
  2: myapp
  3: ^Z
  >> l
  0: @echo Batch file being processed...
  1: mytsr
  -> 2: myapp
  >> q
  Save before exit (Y,n): y

Software for air pressure monitoring and alarm


The sensor display unit is furnished with RS232 (or RS485) interface. A serial command can be sent to the unit and it will respond with measurement value. Python data collection software running on a Linux PC issues sampling commands continuously. When airguns are fired the software extracts the highest pressure value that had been registered lately, in order to plot plot air pressure as function of shot number. The result is shown below. Other process parameters are also sampled.

Overvåkning av GUNCO, trykk fra seismikk-kompressor, streamer "Birds", navigasjon DOL (Distance Off Line)


Et Linux-basert system som samler inn og presenterer informasjon fra:

  1. Skipets Survey Computer, som sender ut informasjon på serieport om siste skuddspunktsnummer
  2. Skipets navigasjonsutstyr, som sender info om tid/dato og skipets hastighet
  3. Trykksensor, der data hentes hvert sekund, så ekstraheres maksimalt trykk for siste skudd, som da regnes som trykk i skuddøyeblikket (nominelt 138 Bar = 2000 PSI)
  4. GUNCO sender opplysninger om hvilke kanoner som var aktive ved siste skudd, og Delay/Error/Status info
  5. Streamer "Bird" system sender info om aktive "Birds", deres aktuelle dyp og vinkel på vingene (figur viser at atremer'n ligger på korrekt dyp 8 meter, men noen "Birds" må ha stor vinkel på vingene for å klare dette (nr 2, 3, 9) --- maks utslag er +/- 15 grader --- så enkelte seksjoner burde kanskje vært balansert bedre.

All informasjon vises på webside med akustisk alarm hvis egen-definerte alarmgrenser ble overskredet. På denne måten kunne studenter under SVALEX-kursene være alene i instrumentrommet, mens en "usynlig overvåkning" foregikk i parallell.

HVORDAN BRUKE MODERNE GUNCO PÅ FF "KRONPRINS HAAKON" ...?


Innledning


Vi ønsker å se på muligheten for å bruke moderne GUNCO, som modell "HotShot" fra Teledyne, i stedet for vår Geco GUNCO fra ca 1990 (selv om den er pålitelig).

Teledyne, GUNCO modell "Hot Shot


Dept of Geology/ Univ of Tromsø has acquired airgun controller Teledyne, model "Hot Shot". This unit is able to fire either four Bolt/G-guns or two GI (Generator-Injector) guns. Multiple units (max 4) can be combined, so that in total 16 Bolt/G-guns can be used.

Using MOB (Man over-board) input on the "HotShot" airgun contoller


Advise from manufacturer regarding MOB input on the "HotShot" airgun controller:

The man overboard contacts need to be maintained in a closed position for the unit to operate. Once the contacts open the controller will no longer fire. Once closed again it will be able to fire again. So a normally closed pushbutton, with a pull to reset feature is usually what is desired for this. Some users like to have one that is covered as well, so as to not accidentally press it.

TriAcq på RV "Polarstern" i 2003 - interface unit brukt den gangen


Innledning --- problemet som måtte løses


På EUROMARGINS-toktet med RV "Polarstern" i 2003 ble det sendt opp et komplett TriAcq recording system og N3 streamer inkl Birds. Skipets GUNCO og Survey Computer ble brukt. Det var dermed et interface problem som måtte løses den gangen.

TriAcq systemet forventet ved hvert skuddpunkt et telegram sendt over RS232 serielinje Survey Computer. Telegrammet måtte være av såkalt '''NORSTAR Format 4" type, definert i dette dokumentet: NORSTAR-format4-from-ExtHeader-ver-5-8.pdf (PDF)

I tillegg forventet "Streamer Interface" delen av TriAcq en bestemt sekvens av triggesignaler med bestemte polariteter og spenning-/strøm-karakteristikker.

Systemdiagram tegnet av GECO Field Engineer M.G. som deltok under toktet med RV "Polarstern" i 2003.

UNDERSØK: Ble TriAcq re-konfigurert på noe vis, for å kunne arbeide med Navigasjonsutstyr og GUNCO på "Polarstern"? Prøv å spore opp M.G. og spør om han husker dette ...
