A Windows DLL and sample C, VB and Java programs for IMDG Code
Substances and Calculations
(TUPS Libraries)
Author: Exis Technologies Limited, October 2012
This is a toolkit for software developers wanting to integrate IMDG Code functionality into their
own in-house cargo management systems.
With these routines you can retrieve substance data from the Dangerous Goods List (chapter
3.2). Fields such as Name, Class, Marine Pollutant, Special provisions, Packing instruction
number, Limited Quantity, Stowage and Segregation, Properties and Observations are available.
These records are retrievable by UN number and variant. 'Next' and 'Previous' UN numbers are
also locatable. You can also retrieve the general stowage requirements from chapter 7.1 for a
substance, according to its class, subrisks, packing group, etc.
You can also check the stowage and segregation requirements for several substances in a
load; whether it is prohibited, allowed on deck only, or on or under deck, on a passenger or
cargo sailing; and whether the mix of substances need to be segregated from one another.
Segregation is according to the classes and subsidiary risks of section 7.2.1.16 and 7.2.7, the
segregation groups of chapter 3.1, special requirements from the Dangerous Goods List such as
'segregation as for class 5.1 but away from...', and other paragraphs of chapter 7.2. The degree
of segregation required between two loads can also be obtained.
The text of the Special Provisions of chapter 3.3, and the Packing, IBC and Tank Instructions and
Provisions of chapters 4.1 and 4.2 are retrievable by name.
The 32-bit windows DLL is called ctups.dll. Following normal windows conventions, the routines
use the WINAPI calling convention.
There are sample programs with source code written in C and VB. These are intended to show
very simply how the routines can be called rather than to be the basis of a complete end-user
system. We also supply ctups.h (for C) and tupsdecl.bas (for VB) for you to include in your own
programs to define all the routines and constants. For calling from other languages you can use
these as a guide to write your own equivalent. C programs should be linked with the import library
ctups.lib (unless you are doing LoadLibrary and GetProcAddress calls). VB programs need to find
the dll, for instance by puttting it into the <system> directory or your program's working directory.
A similar Java program (Subsdemo.java) is also provided. It uses the same data file and calls
other .class files but does not use the DLL.
The data file is around 2 Mb in size. It is binary and portable between Windows/DOS, VMS,
AS/400 and RS/6000 systems ('big-endian' versions will flip 16-bit integers from low-high to highlow byte order as they read). Accessing a substance record requires just one disk 'seek'.
Packaging Instructions and Consolidated Comments will take several.
The current version corresponds to IMDG Amendment 35-10, published in November 2010. This
was usable during the transition year of 2011 and became mandatory from 1 January 2012.
IMDG Code errata and future amendments will require changes to the data file and possibly to
the routines also. Amendment 36-12 is due to be published in late 2012, and the year 2013 will
be the transition period during which either amendment 35 or 36 can be used.

Getting started with subsdemo.exe or VBexample.exe
The exe files, ctups.dll and subs.ind should be in the same directory. At first you can only look up
UN numbers ending in 0 or 5. Run subsdemo.exe (for a C example) or vbexample.exe (for VB).
To look up a substance, type 1230 in the UN number box, and press 'Substance'. You see the
primary class, packing group, stowage category, limited quantity value, emergency schedule and
packing instruction for Methanol, and the stowage and segregation comments.
UN 1230 var 0 Class 3 PG II Cat B LQ= 1 L EmS= F-E,S-D PI= P001
METHANOL||
Clear of living quarters.
Type 2430 and press 'Substance'. You see variant 1 of ALKYLPHENOLS, SOLID, N.O.S., with
qualifying descriptive text and a variation description 'Packing group I.' after the name. Type 2
into the variant box, press 'Substance' again, and see the second variant.
To look up a packing provision, type PP4 in the phrase name box and press 'Phrase'.
PP4 For UN 1774, packagings shall meet the packing group II
performance level.
To see a special provision, type 191 into the box an press 'Phrase' again.
Receptacles with a capacity not exceeding 50 ml containing only
non-toxic constituents are not subject to the provisions of this Code.
Examples of other phrases are: packing instruction (P302), IBC instruction (IBC02), tank
instruction (T3), IBC provision (B6), tank provision (TP10).
To check for segregation requirements within a load, start a load by clicking the radio button for
'Closed / Passenger'. Type 1790 in the UN number box, 2 in the variant box, and press 'Add to
load'. You see return code 97 - this substance is not allowed on passenger sailings. Start another
load by clicking the radio button for 'Closed / Cargo'. Press 'Add to Load', and this time it is
allowed (return code 0). The label numbers (bitsfields 4000 and 800) are decoded as primary
class 8, subrisk 6.1 (refer to the description of function TupsLabCom). Add another substance by
putting 1230 and 0 in the UN and variant boxes, and press 'Add to Load'. There is no clash, and
class 3 (bitfield 20) is added to the labels. Add a few more substances (e.g. substances 1400,
1515, 3250), and you will start to see clashes - a set of 3 numbers means substance sequence
number 'i' clashes with number 'j', and the degree of segregation required is 'k'. You may also see
return code 98 - this substance is only allowed in tanks (e.g. substance 3250).
Having built one load you can check how it should be segregated against another one. Start the
second load by clicking the radio button for 'Closed / Second', and add a few substances to that.
In this case the set of 3 numbers means that substance sequence number 'i' in load one clashes
with number 'j' in load two and the degree of segregation required is 'k'. For a more complete
explanation refer to the technical document section "Compatibility between loads".
Recompiling the sample programs
Subsdemo is a small, simple windows program. If you want to add more features, edit the .cpp or
.rc file. makedemo.bat compiles and links the program. This works with Microsoft C++ versions 5
and 6. Slight changes may be needed for other compilers. It assumes that 'cl', 'rc' and 'link' are to
be found in the path, an that environment variables INCLUDE and LIB point to the standard .h
and .lib files.
VBexample is an equivalent program in VB, which is most easily worked with inside Visual
Studio. If you want to run the program from inside Visual Studio, it is easiest to uncomment the
'ChDrive' and 'ChDir' calls in 'Sub Form_Load', and set the values to your own working directory.
Specification of the routines
Initialization
int TupsInit(char *name)
Function TupsInit (ByVal fname As String) As Long
This should be called first. It opens the substance file and performs various initializations.
name
the filename, "subs.ind", with any necessary directory specification.
return value
-1 = Can't open file
-2 = Can't get enough memory (unlikely, except in 16-bit versions)
-28 = Unactivated copy.
Other negative values = various copy protection failures.
+ve = OK (the file handle of subs.ind)
With an unactivated copy and other protection failures, the system works in 'demo mode'.
This only accepts UN numbers ending in 0 or 5, and some of the fields of the dangerous
goods list are blank (struct tups, elements pp, ibci, ibcp, tankun, tankimo, tankp,flash and
explim; specprov shows only the first provision)
Substance Lookups
int TupsSub(int un, int suffix)
Function TupsSub (ByVal un As Long, ByVal suf As Long) As Long
Finds a substance on file.
UN number
suffix
un
suffix
Note: Where a UN number has no variants, it will be have suffix 0 (e.g. UN 2050, suffix
0). Those with variants are numbered 1 upwards (e.g. 2810 suffixes 1, 2 and 3 are for
packing groups I, II and III). A search for suffix 0 or 1 will equally find either of 0 and 1.
Alternatively, suffix may be -1 or -2, to find the respectively the next or previous UN
number (and suffix 0 or 1) to the one specified.
return value
99 if no such substance
0 = OK
int TupsRead(int field, char *buf)
Sub TupsInfo (ByVal field As Integer, buffer As Any)
TUPS_STOW*
Sub TupsRead (ByVal field As Integer, ByVal buffer As String)
'used for TUPS_INFO and
'used for other values
Reads data for the substance last found with TupsSub. 'buf' can be variously a pointer to
a char array, an array of shorts or a 'struct tups' into which the data will be copied. Note
that the user must provide a buffer of sufficient size.
field
TUPS_NAME retrieves Proper Shipping Name, qualifying descriptive text
and variation comments. A '|' character (ascii 124) separates the three
items, and a NULL terminates it. The string may include embedded
linefeed characters.
TUPS_STOW retrieves (as an array of shorts, terminated by a zero) the
stowage and segregation phrase codes from column 16 of the
Dangerous Goods List. See TupsCom for converting the codes to
printable phrases.
TUPS_STOWC retrieves general stowage comment codes applicable to
Cargo ships, for this class, subrisks, packing group, etc, from chapter
7.1 of the code.
TUPS_STOWP ditto for passenger ships.
TUPS_PROP retrieves as text the properties and observations from column
17 of the Dangerous Goods List.
TUPS_INFO retrieves assorted data from the Dangerous Goods List:struct tups
{
short un;
// UN number
short suf;
// suffix
char prim[5]; // primary class
char secn[6]; // secondary class (subrisk)
char tert[4]; // tertiary class
char mp;
// Marine pollutant, null, Y, S (=severe, PP) or C
(=conditional, bullet)
char ulineems;
// Underlined EmS. 1 = fire, 2 = spillage, 3 = both
char ems [8];
// Emergency Schedule
char classcode[5]
// ADR classification code
char flags;
// additional user data required - see below
char specprov[28];
// special provisions
char lq[10];
// limited quantity
char pi[16];
// packing instructions and provisions
char pp[26];
char ibci[11];
// IBC instructions and provisions
char ibcp[15];
char tankun[7];
// tank instructions, UN, IMO and provisions
char tankimo[9];
char tankp[25];
char flash[26];
// flashpoint
char explim[28];
// explosive limits
char scat[3]; // stowage category, A to E or 01 to 15
char pg[4];
// packing group, null, I, II or III
char state;
// S,L,G,E,A for solid, liquid, gas, explosive substance or
explosive article
};
which is declared in an H file.
or 'Type tups' which is declared in tupsdecl.bas
Note that there are 2 versions of this routine for VB, 'TupsRead' to return a string,
and 'TupsInfo' to return an array or a 'tups' structure.
The value returned in 'flags' indicates whether any additional information is required from
the user to print on a Dangerous Goods Note or manifest. It is the combination of:1
Technical name required (special provision 274 and others)
2
Possible marine pollutant
4
Flashpoint required (class 3 or subrisk 3)
8
Control and emergency temperatures (items under temperature control)
16
Radionuclide, category, activity and transport index required (class 7)
32
May be carried in limited quantity
64
Net explosive content required (class 1)
128
Warn user about special provisions 900 (certain formulations are prohibited)
int TupsCom(short code, char *cbuf)
Function TupsCom (ByVal code As Integer, ByVal buffer As String) As Long
Obtains the comment text related to a numeric comment code. The text will be nullterminated and may include linefeed (ascii 10) characters.
code
code number (retrieved from TupsRead) to look up
cbuf
char array into which the phrase will be copied
return value
0 = OK
1 = no such comment.
int TupsPhrase(char *code, char *cbuf)
Function TupsPhrase (ByVal name As String, ByVal buffer As String) As Long
Obtains the text related to a text comment code. The text will be null-terminated and may
include linefeed (ascii 10) characters. The codes may be packing instructions Pxxx, IBC
instructions IBCxx, tank instructions Txx, packing provisions PPxx, Bx or TPxx, or special
provisions, numeric. Provisions retrieved by TupsRead may include several codes (e.g.
"PP25 PP26 PP31") separated by spaces. It is for the user to split these into separate
null-terminated codes for this routine.
code
phrase name to look up
cbuf
char array into which the phrase will be copied
return value
0 = OK
1 = no such comment.
Hint: If the user enters a UN number, call TupsSub for that UN number and suffix zero. For an
return code of 99 tell him 'invalid UN number'. Otherwise, if it retrieves suffix zero, there are no
variants and you can show him the substance details. If it retrieves variant 1, call
TupsRead(TUPS_NAME... to get the description of the first variant, then TupsSub and TupsRead
for variants 2, 3, etc until a return of 99 indicates no more variations. Ask him to select one.
Checking a Single Load
void TupsNewLoad(int mode, int type, short *clashlist, int max_clash)
Sub TupsNewLoad (ByVal mode As Long, ByVal utype As Long, clist, ByVal les As Long)
For validation of a single load, this empties the load, and specifies whether it is to be
checked for passenger or cargo sailings, and open or closed units, or a tank.
mode
TUPS_PSNGR for a passenger sailing
TUPS_CARGO for a cargo sailing
and may be or'ed with
TUPS_NOCHECK to suppress validation as each substance is added.
type
TUPS_OPEN
TUPS_CLOSED
TUPS_TANK according to the unit type
clashlist
array of shorts which becomes filled with triplets describing each clash
a) sequence number of first substance counting from 1
b) sequence number of second substance
c) degree of clash - see values 1 to 10 for TupsAddSub
The list is terminated by a zero value. With a single load (a) < (b).
With VB, pass the first element of the array, clashlist(0)
max_clash
maximum number of clashes to report. Filling of clashlist stops when this
is reached. Thus clashlist can be dimensioned to [3*max_clash +1].
int TupsAddSub(int un, int suffix)
Function TupsAddSub(ByVal un As Long, ByVal suf As Long) As Long
Adds a substance to the load, and (unless TUPS_NOCHECK applies) validates it against
the load so far. Details of clashes with previous substances will appear in 'clashlist'
un
suffix
UN number
suffix
return value
99 if no such substance
98 if not valid in a tank / must be in a tank, when this unit isn't / is a tank.
97 if substance prohibited (entirely, or on this passenger sailing).
96 if this explosive is not allowed in this open unit.
88 if failed to expand working space (16-bit versions are limited to about
440 substances in a single load).
1 to 10 highest clash value if this substance clashes with others already
in the load.
0 if no clash or if TUPS_NOCHECK is set.
With a return value of 88 upwards, the substance is not added to the load, and so is not
checked against future substances which will be added.
Return values 1 thru 4 are 'away from', etc, as in section 7.2 of the IMDG Code.
1
"Away from"
2
"Separated from"
3
"Separated by a complete compartment or hold from"
4
"Separated longitudinally by an intervening complete compartment or hold from"
We also use numbers 5 to 10 in relation to explosives:
5
If UNDER DECK – "Separated from". If ON DECK - not less than 6 metres apart.
6
As 4, and also as remote as possible from each other.
7
As 4, and also as remote as possible from each other, and not more than 50 kg
total net explosive mass per ship.
8
As 4, and also as remote as possible from each other, and not more than 10 kg
total net explosive mass per ship.
9
Not on same ship
10
If UNDER DECK – As 4. If ON DECK - not less than 6 metres apart.
Note: In setting the highest clash value, 5 is more severe than 2, but less than 3.
Hint: Items carried in limited quantities (see IMDG chapter 3.4) are allowed on or under
deck on both passenger and cargo sailings, need not bear hazard labels, and need not
be segregated from other incompatible goods. Don't call TupsAddSub for limited quantity
substances.
int TupsEditLoad(int seq, int un, int suffix)
Function TupsEditLoad (ByVal seq As Long, ByVal un As Long, ByVal suf As Long) As Long
Changes a substance in a load, but does not recheck the validation.
seq
sequence number within the load, numbered from 1 upwards.
un
UN number (or zero to remove it from the load)
suffix suffix
return value
99 to 96 as with TupsAddSub
0 = OK
int TupsReCalc()
Function TupsReCalc () As Long
Re-validates a load, if it was originally defined as TUPS_NOCHECK, or when one or
several changes have been made with TupsEditLoad.
return value
0
if no clash
1 to 10 highest clash value if a clash.
void TupsLabCom(short *lab_com)
Sub TupsLabCom (labcom As Integer)
retrieves the aggregate list of labels and stowage comment codes for the items in the
load.
filled with a list of consolidated label and comment data for the current
load.
lab_com[0]
bitfields for primary labels
lab_com[1]
bitfields for subrisk labels
lab_com[2...] comment codes. Use TupsCom to convert to phrases.
With VB, pass the first element of the array, lab_com(0)
lab_com
The bitsfields for labels represent (in hex):
0001
0002
0004
0008
0010
0020
0040
0080
0100
0200
0400
0800
1000
2000
4000
8000
marine pollutant
explosive (1)
flammable gas (2.1)
non-flammable gas (2.2)
toxic gas (2.3)
flammable liquid (3)
flammable solid (4.1)
spontaneous combustible (4.2)
dangerous when wet (4.3)
oxidizing substance (5.1)
organic peroxide (5.2)
toxic (6.1)
infectious (6.2)
radioactive (7)
corrosive (8)
miscellaneous (9)
Bit '1' for a primary label indicates a marine pollutant label is definitely required. '1' for a
secondary label indicates one may be required, depending on concentration or
composition (at least one item was 'marine pollutant bullet', but none were definite marine
pollutants)..
lab_com[2] will always be 1 (prohibited), 2 (as approved by competent authority), 3 (ondeck only) or 4 (on or under deck). Some other values later in the list will restrict the load
to various parts of a ship, e.g. 32 (Clear of living quarters) or 60 (Stow in a well ventilated
space).
Compatibility between loads.
Having built one load with TupsNewLoad and TupsAddSub, TupsNewLoad can be called again
with a mode of TUPS_SECOND Tups_AddSub is then called for each substance in the second
load.
Note:
a)
b)
c)
d)
e)
if the first load was known to be valid, time is saved if it is built with a
TUPS_NOCHECK flag.
further loads can be checked against the first with more TupsNewLoad /
TUPS_SECOND calls.
TupsEditLoad, TupsReCalc and TupsLabCom are not appropriate with a
TUPS_SECOND load.
in 'clashlist', (a) is the sequence number of an item within the first load, (b) within the
second.
to check ten loads against each other build load one as a first load, then check it
against loads two to ten in turn. Then build load two as a first load and check it
against loads three to ten in turn, and so on, i.e. you need to use a nested loop.
Notes for VB users
In the above descriptions, 'short' means 'Integer', 'int' means 'Long', and 'char*' means String. The
function declarations are thus:Function

TupsDistance (ByVal opclo As Integer, ByVal degree As Integer, ByVal shiptype As
Integer, ByVal ondeck As Integer, foraft As Integer, athwart As Integer, notes As
Integer)
To pass an array to the DLL, pass the first element. So for example, the call to TupsLabCom is
Dim labcom(40) as Integer
call TupsLabCom(labcom(0))
There is an extra declaration 'TupsInfo', which is the same as TupsRead, but with the second
argument of type 'tups' so you can call
TupsInfo (TUPS_INFO, details)
Null-terminated strings are not handled nicely in VB, so the sample program includes a
Function sTrim(s As String) As String
which converts a null-terminated string to a VB String
The Java routines
Subsdemo.java is a small demonstration program written in Java. The Java routines it calls are
thread-safe, so they could be used by a multi-threaded server application. There is one static
class 'Tups' which controls the data file and is used for phrase lookups. An instance of a class
'DGSubs' is used for substance lookups, and one of class 'DGLoad' is used for load validation.
The routines can be operated with two data files open, for instance during an IMDG transition
year, when the files may be for two different amendments. Substance lookups and load validation
can be done against either of the files.
class Tups
public static int start(String filename, int ver)
This should be the first routine called. On an initial call it opens the data file and does various
initialisations. Subsequent calls to the routine for the same file number (e.g. by other threads in a
multi-threaded server application) are harmless and have no effect. Any exception of 'file not
found' or a disk read error is caught and returns a 1.
filename
ver
the filename, "subs.ind", with any necessary directory specification.
= 0 or 1, the data file number.
return value
0 = OK
1 = error, probably unable to read the file
public static synchronized void unload(int ver)
This closes the data file, for instance if it needs to be replaced by a revised version without
restarting the application or taking down a server. No other routines should be used until another
call to 'start' has been made to open another file. If the data file is changed and a user has
existing instances of class DGSubs, the next routine called should be TupsSub (to look up a new
substance) rather than one which gets information about the 'current' substance. Similarly, if there
are existing instances of DGLoad, the next routine should be TupsNewLoad to start a new load
rather than continue working with the substances in an existing load.
Calling unload is harmless if the file is not open, and catches any exceptions returned by the file
close.
ver
= 0 or 1, the data file number.
public static int TupsCom(short code, StringBuffer phrase, int ver)
Obtains the comment text related to a numeric comment code. The text may include linefeed
(ascii 10) characters. Calling this without the file being open returns 1, the same as 'code number
not found'.
code
phrase
ver
the comment number
the phrase
= 0 or 1, the data file number when running with 2 amendments.
return value
0 = OK
1 = no such comment number
2 = an exception such as a disk read error has been caught.
public static int TupsPhrase(String phrasecode, StringBuffer phrase, int ver)
Obtains the text related to a named comment code. The text may include linefeed (ascii 10)
characters. The codes may be special provisions (2 or 3 digits, as in IMDG chapter 3.3), packing
instructions (Pxxx or LPxx), IBC instructions (IBCxx), tank instructions (Txx), or packing
provisions (PPxx, Bx or TPxx), as in IMDG chapters 4.1 and 4.2. Calling this without the file being
open returns 1, the same as 'phrase name not found'.
phrasecode
phrase
ver
the phrase name
the phrase
= 0 or 1, the data file number when running with 2 amendments.
return value
0 = OK
1 = no such phrase
2 = an exception such as a disk read error has been caught.
public static int TupsFindIndex(String name, int language, int ver)
Find the location in the index where a name starting with this string would be found.
name
language
ver
the name to be looked up
= 0 for the english index, 1 for the german.
= the file number, 0 or 1
return value
the sequence in the index where such a name would be locate, from
0 at the beginning to a maximum value at the end
public static int TupsIndex(int num, int language, int ver, StringBuffer name)
Return the name at a particular location in the index. The string returned will be fixed format, as
follows:UN number
4 digits, or all spaces
Class
4 characters, e.g. '3', '6.1' or '1.3G'
Marine pollutant 1 character N, Y S, or C for no, yes, severe or conditional
Sort string
10 characters, capitals, ignoring spaces, digits, punctuation, and
standard prefixes
Name
variable length, as printed in the book.
For example, 29333 NMETHYLCHLOalpha-Methyl alpha-Chloropropionate, see
num
language
ver
name
the position number to be looked up
= 0 for the english index, 1 for the german.
= the file number, 0 or 1
set to the name at that location

offered in a menu. Starting with 'selected' as empty will give choices such as "Inner then outer
packaging|Outer then inner packing|Single Packing|IBC|Tank Instruction T7" according to the
packing instructions and provisions for this substance. Calling again with 'selected' equal to one
of those strings such as "Single Packaging" will return a list of the valid single packaging types,

100 = a disk exception has been trapped.
class DGLoad
Constructor
public DGLoad(int maxs)
maxs
An overestimate of the maximum number of substances in the load.
For a value below 16, 16 is used. There is a memory overhead of 50
* maxs for each DGLoad object, so do not set it extravagantly large.
For segregation between loads, maxs needs to be at least 1 greater
than the number of items in the first load.
public int SetLoadVer(int ver)
Set subsequent operations to use the specified file number. File number zero will be used if this
routine is not called. This should not be called after the first substance has been added to the
load.
ver
= 0 or 1, the data file number.
return value
0 = OK.
-1 = Error, ver is out of range, or the data file is not open, or there
are already substance in the load
public void TupsNewLoad(short mode, short unittype)
For validation of a single load:DGLoad.PSNGR (4) for a passenger sailing
DGLoad.CARGO (0) for a cargo sailing
type
DGLoad.OPEN (1) or
DGLoad.CLOSED (2) or
DGLoad.TANK (3) according to the unit type
For segregation checks between this load and others, see later.
mode
public int TupsAddSub(int un, int suffix)
public int TupsAddSub(int un, int suffix, float nec, String groups, int stowseg[])
Adds a substance to the load, and validates it against the load so far.
un
suffix
nec
groups
stowseg[]
return value
UN number
Suffix
net explosive content in kg (ignored except for explosives of
compatibitly groups B, C, D, E, G and N)
code letters for additional segregation group to which this substance
belongs
extra stowage and segregation code numbers to apply to this
substance
99 if no such substance
98 if not valid in a tank / must be in a tank, when the unit type is / is
not a tank
97 if the substance is prohibited (totally, or on this passenger sailing)
96 if the explosive is not allowed in this open unit.
95 if the total net explosive content exceeds that permitted on this
passenger sailing
94 if a port, vessel or operator restriction prohibits this item
100 = a disk exception has been trapped.
88 if MAXSUB items are already in the load.
1 to 10 highest clash value if segregation is required from previous
items.
0 if no segregation required
With a return value of 88 upwards, the substance is not added to the load.
Return values 1 thru 4 are 'away from', 'separated from', etc, as in section 7.2 of the IMDG Code.
We also use numbers 5 to 10 in relation to explosives.
1
Away from
2
Separated from
3
Separated by a complete compartment or hold from
4
Separated longitudinally by an intervening complete compartment or hold from
5
If UNDER DECK - "Separated from". If ON DECK - not less than 6 metres apart.
6
As 4, and also as remote as possible from each other.
7
As 4, and also as remote as possible from each other, and not more than 50 kg total
net explosive mass per ship.
As 4, and also as remote as possible from each other, and not more than 10 kg total
net explosive mass per ship.
9
Not on same ship
10
If UNDER DECK - As 4. If ON DECK - not less than 6 metres apart.
In setting the highest clash value, 5 is more severe than 2, but less than 3.
8
public int TupsEditLoad(int seq, int un, int suffix)
Changes a substance in a load, but does not recheck the validation.
seq
un
suffix
return value
sequence number within the load, numbered from 1 upwards.
UN number (or zero to remove an item from the load)
Suffix
100 to 94 as with TupsAddSub
0 = OK
public int TupsReCalc()
re-validates a load, when one or several changes have been made with TupsEditLoad.
return value
0 if no clash
1 to 10 highest clash value if a clash.
public void TupsLabCom(short lab_com[])
lab_com becomes filled with a list of consolidated label and comment data for the current load.
lab_com[0] - bitfields for primary labels
lab_com[1] - bitfields for subrisk labels
lab_com[2...] - comment codes, terminated by a zero value. Use TupsCom to convert to phrases.
The bitsfields for labels represent (in hex)
1 marine pollutant
2 explosive (1)
4 flammable gas (2.1)
8 non-flammable gas (2.2)
10 toxic gas (2.3)
20 flammable liquid (3)
40 flammable solid (4.1)
80 spontaneous combustible (4.2)
100 dangerous when wet (4.3)
200 oxidizing substance (5.1)
400 organic peroxide (5.2)
800 toxic (6.1)
1000 infectious (6.2)
2000 radioactive (7)
4000 corrosive (8)
8000 miscellaneous (9)
Bit '1' in prims indicates a marine pollutant label is definitely required. '1' is secs indicates one
may be required, depending on concentration or composition. lab_com[2] will always be
1 (prohibited),
2 (as approved by competent authority),
3 (on-deck only) or
4 (on or under deck) - the stowage position according to IMDG.
Some other values in later elements of lab_com will restrict the load to various parts of a ship,
e.g. 32 (Clear of living quarters) or 60 (Stow in a well ventilated space).
public int TupsClashes(short list[], int maxnum)
This returns details of the individual clashes between items in the load. The list is filled with sets
of three numbers being:the sequence number of one item in the load
the sequence number of the item it clashes with
the degree of clash (1 to 10)
the number of clashes stored in 'list', so 'list' can be dimensioned to
3*maxnum+1.
the number of clashes stored in 'list'.
maxnum
return value
The list ends with a zero value for the first sequence number. For validation of a single load the
first sequence number will always be smaller than the second.
Compatibility between loads.
Having built one load with TupsNewLoad and TupsAddSub, TupsNewLoad can be called again
with a mode of DGLoad.SECOND (64). Tups_AddSub is then called for each substance in the
second load, and will check them for segregation from all the items in the first load. Note:a) further loads can be checked against the first with more TupsNewLoad / TUPS_SECOND
calls.
b) TupsEditLoad, TupsReCalc and TupsLabCom are not appropriate with a TUPS_SECOND
load.
c) in TupsClashes, the first sequence number refers to an item within the first load, the second to
an item within the second load.
If one 'first load' is being checked against all the other loads on the ship as 'second loads', a
return value of 95 from TupsAddSub will indicate that the total explosive content of a passenger
ship (IMDG 7.1.7.5) has been exceeded.

(Note that 1065 needs to be 'away from' 1230. However, since both units are 'closed', this requirement is automatically
satisfied, and no clash is reported. 1500 needs to be 'separated from' both 1230 and 1790.)
