This table 1 shows the data that has been taken from the Sima pro and used to
design the Steel structure of this ship. The welding of two different thicknesses
is taken and is assumed that their collective emission data would be equivalent
to the emissions for a 6-7mm 2 thick steel plate. The fiber reinforced cement
tiles have been used as it has the same composition as the deck coverings. The
insulation being used is glass wool which has a density of 100 kg /m 3 . In this
case glass wool that has a 40 kg/m 3 has been used.
In the case of steel structure of the ship
Table 2. Calculations for steel superstructure
The weight of the Structure is = 950 tons (Safedor, 2003)
Total weight carried per year = 1750000 tons/year (Anna Hedlund)
Over a lifetime it would be carrying = 43750000 tons (1750000x25)
The ship travels = 308000 km/year (880 km/day x 350 day/yr) (Anna Hedlund)
Over a lifetime it is 7700000 km. (308000 x 25)
15 The energy used here was taken as a resource input from the nature as unspecified energy because exact
energy source was not mentioned otherwise other and exact forms of energy could have been taken from
technosphere for modeling. Though this does not have any impacts on the lifecycle so it can be assumed
that we can use this energy from the nature than the technosphere. This would be the case with all three
superstructures.
