 ==== To view an oil drift forecast ====
+Take a look at the facility for [[kilden_oilship_wms|Viewing in embedded WMS client]]
 The service includes a rudimentary viewing facility, which is implemented as an embedded WMS client. It is intended to serve as a backup viewing service for met.no's national clients, who normally use their own dedicated GIS to view data files delivered automatically.

 ==== To perform a coupled ship drift - oil drift forecast ====
-[[kilden_oilship_wms|Viewing in embedded WMS client]]
+This facility makes it possible to predict the fate of oil spilled from a drifting ship, as in the "Prestige" accident. In summary, it is done by first performing a ship drift simulation, and then using the position and time information from the drift trajectory as a moving source for an oil spill simulation.
+Take a look at the [[kilden_shipoil_order|order form for oil drift simulation with input from a ship drift trajectory]].
+  - Perform a ship drift simulation as described above. //Note the serial number of the simulation//.
+  - Select **Start oildrift simulation** from the main menu.
+  - Hit the **Get ship trajectory** button. Pops up a //Get shipdirft simulation// window.
+  - Select the ship drift simulation. Edit the oil spill depth and rate, as appropriate. Hit **OK**
+  - Edit list of positions / times / depths / rates if needed.
+  - Fill in other information as necessary:
+      * **Oil type**: Select from the list
+      * **Simulation duration**: The simulation will stop after this period or when the forcing data runs out.
+      * **email**: n/a for Mersea user.
+      * **Description**: Please enter a unique description that is recognizable in the listing.
+  - Hit Advanced options button
+      * Select the **Ocean model**
+         * met.no is for Norwegian waters
+         * default = mercat_o4_glo
+         * mfs_16_med = MFS 1/16th degree model of Mediterranean Sea

+==== To view a ship+oil drift forecast ====
+Same as for viewing any oil drift simulation. Just select the relevant simulation.
+Look [[kilden_oilship_wms|here]] for details on what you see.
