1. One vessel leaves for Port D after loading cargoes at Port A.
The load lines applicable can be seen as follows.

A (Tropic)

B (Summer) C (Winter)

D

*-5460 n miles* 840 n miles-3790 n miles*

Suppose the tropic displacement is AT =20205t, the summer
displacement is AS =19710t, winter displacement is AW=19215 t,
light ship displacement is AL=5565t; the weight for food, crew,
luggage and stores is J₁ =28t, Ship constant is C=200t, Speed is
17.5 knots, time margin at sea is trs 4 days; the fuel and fresh
water consumption at sea is Jj, =40 t/d; The fuel and water supply
can be acquired after 2 days when the vessel arrives at Port D. The
fuel and fresh water consumption at berth

is jb = 15 vd.

Q: What is the max net DWT at this voyage for this vessel?
4. One ship is worth $5 million, and it can run for 10 years,
the residual value at year 10 is $0.3 million. The net revenues at
the end of each year are $2.5 million, the annual

interest rate is 10%.

Q: is worthwhile to invest in this project?

(A/P, 10%, 10)-0.162745

(P/F, 10%, 10)-0.38554

(A/F, 10%, 10-0.062745

(P/A, 10%, 10) 6.1446
