I'm not completely familiar with tonberry's hashing system, but here's what I know, hope it helps.
The animation data for ocean is located on the same texture page as road textures, this is probably also the reason why you got animation to your roads IF you tried to "scale" it over animation data (again, not very familiar how tonberry works.
Ocean's tim texture is located in wmset.obj and in wmsetXX.obj files. The reason why it isn't in texl.obj is probably because the animation data may be done for 128x128 sized textures and all the textures in texl.obj are in 256x256 format. This also means that ocean textures are in 128x128 tim, but luckily I can do some magic with the exporter/importer and "upscale" textures through texture coordinates and later through geometry editing.
