Case illustration on how TANKER4004 can be used to schedule a fleet of 7 VLCC for a period of 6-12 months.


Assume our company "owns" four VLCCs

Additional requirements

Ship availability
When we start a schedule, we need to specify the expected port and date where/when vessels are open for scheduling.

 

Drydocking information
Drydocking is quite often an issue where chartering must work closely with technical department to find a suitable time and place for docking.
If any of the vessels are planned for drydocking during the scheduling period, we need to specify this.

Assume that  FRONT CENTURY is planed for drydocking during this scheduling period.
Technical department has said that they can drydock in either of Singapore or Lisboa with info as shown below

DISTANCES
Tank4004 includes an automatic distance table. So when the user specifies a sailing from say SIDI KERRIR to Rotterdam, the program immedalitely retrieves such distance and will also tell if routing via Suez or Panama is more optimal.

CARGOES TO BE LIFTED
The illustrative screen below shows that info is divided into three areas:

1) Load/Discharge port with port costs

2) Cargo information:Type of cargo
Stowage
Min/Max cargo to be lifted in each shipment
Freight rateFor tankers WS basis rate plus contract rate (Or expected spot rate)

3) JOB data
In  Tanker4004 each lifting is refered to as a JOB.
JOB data links to the trade info (ports etc) plus info about laydays for the shipments

The cargoes to be lifted are in this case shown as quarterly spot lifting. The user has specified the WS expected for each of the trade routes for each quarter

 

SELECT VESSELS TO BE TAKEN IN ON TC
In our case we assume that there are three tc vessels available ijn the market:
SAHBA, DORRA and GHAZAL

We can fix one, two or three of these vessels. The user has specified the expected TC rate to apply. When Tank4004 is run, the program will analyse what is most profitable. This is a very powerful function that enables the user to see the whole fleet and which tc vessels(s) are most profitable overall.

FUEL PRICES
Since cost of fuel is an important and significant item, Tanker4004 has a flexible system available for specifying relevant fuel prices:

A) We can distinguish between all bunker qualities: HVF, MDO, GASOIL etc

B) We can specify a "global" price to apply for all scheduled sailings. We can for this purpose use Rottredam or USG prices:

In our example we use following prices:
HVF: 600 USD/mt
MDO: 900 USD/mt
GO: 1,100 USD/mt

C) If we wwnt to apply more "correct" fuel prices, we can specify fuel prices applicable for all the relevant fueling ports that we include in our scheduling. I.e. we do not need prices for all the world, we need to update those ports where we typically take fuel.

In order to facilitate fast specification, we can specify fuel prices in these ports either as the full local price or as a differential to Rotterdam prices.

D) If the user takes bunker at the expense of cargo, this can be specified.

 

CANAL TOLLS
Tanker4004 includse an updated list toll tarifs for Suez and Panama tolls. Canal tolls will automatically be calculated based on vessels' SUEZ and PANMA TONS.

Canal restrictions such as LOA, BEAM or DRAFT will automatically be matched against potential ships to be scheduled through any canal.
Of particular imprtance is the automatic calculation of cargo intake based on any draft restrictions.

CURRENCY

Tanker4004 can work in any currency: Canal tolls may be in SDR, Fuel price in USD, Cargo rate in EUR, etc.. The user will specify a currency table and can select which currency to be used for corporate view.

VOYAGE ESTIMATOR

At the core of Tanker4004 is a powerful Voyage estimator. The user can run this separately, but keep in mind that what Tanker4004 is doing when it is searching for an "optimal" schedule, it goes thorugh hundreds if not thousands of voyage calculations to find the best overall schedule. This is where Tanker4004 stands out from any other voyage estimation systems: It enable "automatic" calculation.
