FEATURE OBJECT ATTRIBUTES


Attribute: vessel's measurements

Acronym: VSLMSM Code:

Camel case: vesselsMeasurements

Attribute type: Complex


Definition:

Multitude of terms and definitions specifically related to vessels. (http://en.wikipedia.org; 24 July 2010)


Sub-attribute Camel Code Identifier Multiplicity Sequential
VSLCAR vesselsCharacteristics 1 n/a
VSLVAL vesselsCharacteristicsValue 1 n/a
VSLUNT vesselsCharacteristicsUnit 1 n/a
COMPOP ComparisonOperator 1 n/a











Comments:


VSLVAL has been set to REAL assuming 3 decimal places, i.e.: 10.000 m.

That would give the result:
1. VSLMSM [VSLCAR=5 (draught); VSLVAL=10.5; VSLUNT=1 (m); COMPOP=2 (>=) ] the regulation applies for vsl of 10.5 m draught and above
2. VSLMSM [VSLCAR=6 (deadweight); VSLVAL=2000; VSLUNT=4 (tons); COMPOP=5 (=) ] the regulation applies for vsl of exactly 2000 DWT
3. VSLMSM [VSLCAR=10 (L.O.A.); VSLVAL=150; VSLUNT=1 (m); COMPOP=3 (<)] the regulation applies for vsl of less than 150 m length

Using a further example:
4. [VSLMSM [VSLCAR=10 (L.O.A.); VSLVAL=50; VSLUNT=1 (m); COMPOP=1 (>)]], CATVSL=3 (tanker), LOGCON=1 (and), LIMTYP=2 (required); associated to a PILBOP object: tankers with LOA > 50.0 m must use the PILBOP

In an example for tankers between 50 and 100 m in length, the coding is like this:
5. [VSLMSM [VSLCAR=10 (L.O.A.); VSLVAL=50; VSLUNT=1 (m); COMPOP=1 (>)], [VSLCAR=10 (L.O.A.); VSLVAL=100; VSLUNT=1 (m); COMPOP=3 (<)]], CATVSL=3 (tanker), LOGCON=1 (and), LIMTYP=2 (required); associated to a PILBOP object: tankers with LOA > 50.0 m and < 100.0 m must use the PILBOP
