Background
This applies to vessels using tanks for multiple purposes, e.g. tankers which can carry both oil cargo, chemical cargo and slop in the same tank or offshore vessels which can carry oil products dirty oil products and bunker in the same tank.
Telscope's solution for this types of tanks have changed as of version 1.36. This guide is intended for vessels that have used the previous version. Vessels registering such tanks for the first time are referred to the user manual.
Previously the solution in Telscope was to double register tanks, e.g. tanks were registered both as OIL_CARGO and CHEM_CARGO and SLOP to account for recording in Oil Record Book Part II and Cargo Record book. If you have tanks with the same name registered multiple time with different tank type, this guide is intended for you. Removing such duplicated tanks will eliminate many potential errors and is the recommended and only supported way of handling such tanks in TELSCOPE.
What to do: Removing tank duplicates
1. Registering tanks as multi-purpose tanks
Go to Settings →Tanks and select OIL_CARGO as type of tank.
Check the relevant types in the column "Can be used as".
- Chem cargo: If the tank can carry chemical cargo recorded in Cargo Record book.
- Slop: If the tank can be used for slop, recorded in Oil Record part II.
- MDO: If the tank can be used for carrying bunker for the vessels own usage, recorded in Oil Record Book part I.
2. Remove duplicated tanks
Important note!
When tanks are removed, associated data, e.g. quantity retained in tank, is lost. To keep the record keeping consistent and correct, duplicated tanks should be removed only when they are not in use. The easiest way to ensure this, is to remove tank duplicates when a tank is used for oil cargo.
The final step is to remove duplicates of existing OIL_CARGO tanks. It is important that only the tank of type OIL_CARGO is kept. All duplicates should be removed. Look for tanks of type CHEM_CARGO, SLOP and CARGO.
Removing tanks is simple: Go to Settings → Tanks and choose relevant Type of tank. Remove by clicking "Remove tanks" and then press "Save".
