Voyage Estimating – A Simplified Example

————————————————————————————————————————————————————-
This article attempts to provide you with the basics of voyage estimation based on a full and complete cargo from one port. All aspects of the voyage calculation and supplementary information have all been simplified.
————————————————————————————————————————————————————-
You are an Owner. You have received an indication from Charterers for cargo from Houston, TX, USA to Moji, Japan for the carriage of fertilizer. The inquiry reads:
 
“+++
Charterers invite Owner’s best for following:
 
12,000MT FERTILIZER, 5PCT MOLOO
1SBSP HOUSTON, USA/ 1SBSP MOJI,JAPAN
FEB 1~10,2009
FIOST
LOAD/DISCHARGE 4,000MT PWWD SHINC
NO ADD/NO COMM
+++
 
You search your internal position lists and find the closest suitable open vessel is expected as follows
 
N/OPEN: MIAMI, FL, USA ON JAN 31ST, 2009
NAME: M/V RICHVESSEL
DWT: 17,324 mt
YR BUILT: 1987
FLAG: Philippines
CLASS: LR
SPEED: 13
BUNKER: F.O. 30 MT PD
D.O. (AT SEA) 2MT PD
D.O. (AT PORT) 4MT PD
LOA/BEAM: 145.50m / 21m
HOLDS/HATCHES: 5/5
GEAR: 5 SETS X 25MT (SINGLE) HORIZONTAL SLEWING
CRANES GEMINI = 1 SET = 2 X 25MT = 50MT (USING
#2 & 3 TWIN CRANES)
 
Now, let’s get into the voyage calculation. I normally like to start from the time component. Total time, in this situation, is the (1) ballast leg, (2) loading time (3) transit time, (4) discharging time and (5) weather.
 
“Rotation          Description                          Days
Savannah    
Houston           Sail 1,354 nautical miles        5
Moji                  Sail 9,669 nautical miles
     via Panama                           31
Weather            Factor 5%                              2
Houston            Loading                                 3
Moji                  Discharge                              3
                                                                    44 days”
TIPS
There are many free sources of distance tables available on the Internet. Here are just a few:
 
The next step is to gather all the cost components up. Many prices you will already have at hand but some prices you may need to ask a local port agent. Our costs are: 
Port costs @ Houston                              USD 25,000
Port costs @ Moji                                    USD 28,000
Canal fees @ Panama                             USD 40,756
Other expenses:                                       USD 3,000
Daily hire rate of vessel:                          USD 528,000
USD 12,000 pdpr x 44 days
Bunker Costs @ Sea                                 USD 356,212
     IFO380 x 30mt/day x USD 280/mt x 38 days
     DO x 2mt/day x USD 487/mt x 38 days
Bunker Costs @ Port                                 USD 11,688
     DO x 4mt/day x USD 487/mt x 6 days
                                                                  USD 992,656
TIPS
Here are a couple of tools to familiarize you with the above costs:
 
Panama canal costs:
Bunker prices
 
Given the total costs of USD 992,656, the breakeven freight rate would be USD 82.72/mt. I will not go into how much we should expect from our investments – I have decided to make my initial firm offer @ USD 100 pmt.
You subsequently draft your firm offer for the voyage business as follows:
OWNER’S ARE PLEASED TO OFFER FIRM AS FOLLOWS:
