Proiect TTM – CargoplanPasta de indigo. Vopsea de

culoare albastra preparata din frunzele si tulpinele plantelor Indigo, indigene in Indonezia, India, Egipt etc. Se expedieaza in stare de pudra sau de pasta, deobicei in sub forma unei paste. A se impacheta in pachete captusite cu un material care previne infiltratia sau contaminarea mediului. Este o marfa valoroasa, se recomanda inspectarea ambalajului si refuzarea oricarui container care prezinta urme de fortare sau manipulare gresita. Trebuie stocate intr-o loc special amenajat pentru a preveni poluarea mediului.

On the displacement sheet we calculate it and its centre of gravity: D = 8149 T LCG = 58.65 M VCG = 6.03 M

At the displacement of 8149 tonnes the following values are determinated by linear interpolation from Chapter XV – HYDROSTATIC PARTICULARS:

Corresponding draught, d0 = 5.669 M Transverse metacentre height, TKM = 7.361M Longitudinal centre of buoyancy, LCB = 62.379 M Longitudinal centre of flotation, LCF = 60.713 M Moment to change trim one cm, MCT = 107.9 T ∙ M

Trimming lever – the distance between LCB and LCG; trimming lever = LCB – LCG. When LCG is aft of LCB the trim will be by the stern. When LCG is forward of LCB the trim will be by the head.

Trimming lever = 3.729 M aft

Draught on fore perpendicular, dfore:dfore = daft – TR [M]dfore = 4.265 M Nava apupata

METACENTRIC HEIGHT (SOLID), GMSOLID

GMSOLID = TKM –VCG [M]

GMSOLID = 1.331 M

CORRECTED METACENTRIC HEIGHT (FLUID), GMFLUID

GMFLUID = GMSOLID – CORRGM [M], where: CORRGM is the free surfaces correction

CORRGM = TOTAL FSMGM / D [M]

TOTAL FSMGM = 1132 T ∙ MCORRGM = 0.087 MGMFLUID = 1.244 M

KGCORR = VCG + CORRGM [M]KGCORR = 7.274 M

To comply with IMO Resolution A.749 (18), the Master must be sure that the vertical centre of gravity, increased with the free surfaces correction, is less than the permissible KG value (see Chapter XII).

KGPERMISSIBLE = 7.30 M

KGCORR < KGPERMISSIBLE ; 7.274 M< 7.30 M

From Chapter XIX – IMO WEATHER CRITERION by double linear interpolation for corresponding draughtd0 = 5.669 M and KGCORR = 7.274 M, K = 6.229 > 1.

To calculate the righting levers curve the following formula is to be used:

GZΘºSOLID = KN – VCG ∙ SIN Θº

GZΘºLICHID = GZΘ

ºSOLID - CORRGZΘº ,

CORRGZΘº = TOTAL FSMGZΘº / D, where:

KN values will be found by interpolation from Chapter XVI – TABULATION OF THE CROSS CURVES OF STABILITY, KN.

CORRGZΘº is the free surfaces correction for GZ levers from Chapter XIII – FREE SURFACES MOMENT.
