STEEL CARGO CLAIMS / VENTILATION PRACTICES
ÇELIK YUK CLAIMLERI/HAVALANDIRMA UYGULAMALARI
Ttransit related damage to steel cargoes on account of improper ventilation practices
and condensation related issues. While most Masters and
Chief Officers are no doubt
aware of the importance of ventilating cargoes during the voyage, it has become
increasingly more common to find officers that are not aware of the specific
requirements for proper ventilation of steel cargoes.
Transit ile ilgili yük hasarlar genelde uygun olmayan havaland rma uygulamas yap larak
ambar içindeki yo unla rmay art lmas ndan olu maktad r.Bir çok kaptan ve ikinci
kaptan sefer boyunce yükün havaland lmas na önem verirler fakat bu konuda özel
isteklere uygun havaland rma yapan ikinci kaptan bulmak oldukça zordur.
In many cases, vessel Masters and/or Chief Officers are of the opinion that steel
cargoes are to be ventilated as much as possible during periods of good weather. This
practice, of course, gives no consideration to the prevailing humidity conditions, dew
points and temperatures.
In most cases, when ventilation is carried out in this manner
without proper regard for dew point and relative humidity, condensation in the form
of cargo sweat and/or ship's sweat will form resulting in potentially significant cargo
claims.
Bir çok olayda gemi kaptan ve ikinci kaptan iyi havalarda yükün havaland raca fikrine
sahiptirler.Fakat pratikte yükün havaland lmas mevcut neme,s cakl a ve yo unla ma

relative humidity dikkate al nmaz ve
ambar içinde yo

claimlerle kar kar ya gelinir.
Vessel Owners should take steps to insure that their Masters and Chief Officers are
aware of the proper steps to be taken in order to determine whether ventilation of a
steel cargo is necessary. In order to determine whether or not to ventilate a cargo
hold loaded with a steel cargo, the dew point of the outside air should be compared to
the dew point of the air within the hold. Owners should insure that their vessels are
provided with a hygrometer (an instrument consisting of both a wet and dry bulb
thermometer that is utilized to determine dew point/relative humidity). Furthermore,
inexpensive portable wet/dry bulb thermometers should be placed in each cargo hold
in order to determine the dew point of the air in the cargo hold. A sling psychrometer
can also be utilized to measure dew point in the cargo holds.
Gemi sahibi gemi kaptan ve ikinci kaptan n vantilasyon yap lmas
veya yap lmamas ile

Gemi sahibi gemide uygun bir hygrometr( slak kuru termometre dew point/relative
humidity belirlemek için)oldu undan emin olmal r.Her ambara pahal olmayan bu
termometrelerden koyarak ambardaki dew pointi belirleyebiliriz.veya bir
psychrometer(nem ölçer)de kullan labilir.
The basic dew point rules relating to ventilation are as follows:
Vantilasyonla ilgili ana havaland rma kural k saca öyledir.
If the dew point of the air inside the cargo hold is lower than the dew point of the
outside air, ventilation should NOT be carried out.
