Proiect TTM – Cargoplan

Utilizand datele individuale si mersul de calcul de mai jos intocmiti cargoplanul initial pentru cargoul de 8700 tdw.

Obtineti toate datele si informatiile necesare despre marfa din Thomas’ Stowage (si oricare alt mijloc informational). Prezentati caracteristicile marfii, tipul de ambalare, modul cum se pregateste nava pentru acel tip de marfa, conditiile de manipulare si transport, avarii care pot aparea la marfa (daca este cazul) in timpul manipularii si in timpul transportului, etc.

Loading condition: SF = ..........., Tip marfa:............................., Tip incarcare:.....................

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

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

Corresponding draught, d0 = ......... M Transverse metacentre height, TKM = ......... M Longitudinal centre of buoyancy, LCB = .......... M Longitudinal centre of flotation, LCF = .......... M Moment to change trim one cm, MCT = .......... 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 = ......... M

Trim, TR

Draught on aft perpendicular, daft:

Draught on fore perpendicular, dfore:

dfore = daft – TR [M]dfore = ..... M

METACENTRIC HEIGHT (SOLID), GMSOLID

GMSOLID = TKM –VCG [M]

GMSOLID = ........ M

CORRECTED METACENTRIC HEIGHT (FLUID), GMFLUID

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

CORRGM = TOTAL FSMGM/D [M]

TOTAL FSMGM = ......T ∙ MCORRGM = ...... MGMFLUID = ...... M

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

KGCORR < KGPERMISSIBLE ; ...... M < ...... M

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