Currently, it has been a trend for many shipping companies and lessor to increase the stacking load due to bigger capacity of the vessel's own tank top design into her hold.

Consequently, as per each shipping company's own preference, their conception as to what is the basic MGW applied for the stacking load value (per respective vessel construction facilities) is difference as noted below:

eg., in general, when deciding the stacking load; there're 4 kinds of basic standards as under-noted:

a) 24 ton with 10 highs stacking into the hold:

  24,000 kgs (10 tiers-1 ) x 1.8g (safety factor for dynamic force )÷4=97,200 kgs per corner

   post

  ∴allowable stacking load for 1.8g=(97,200 kgs x4) ÷1.8=216,000kgs






   
   b)32.5 ton with 8 highs stacking into the hold:

  32,500 kgs x (8 tiers -1)x1.8g ÷4=102,375 kgs per corner post for Seacube reefer in MCIQ

∴allowable stacking load for 1.8g=(102,375 kgs x4) ÷1.8=227.500kgs





 

c) 28.333 ton x (9tiers -1)x1.8g ÷4=102,000 kgs per corner post For Seacube reefer in QCRC 

                                                                 & Dongfang

∴allowable stacking load for 1.8g=(102,000 kgs x4) ÷1.8=226,666kgs

d) 34 ton x (8tiers -1)x1.8g ÷4=107,100 kgs per corner post for ONE reefer in QCRC

∴allowable stacking load for 1.8g=(107,100 kgs x4) ÷1.8=238,000kgs

End report
