Modes of operation that simply uses the tweak of a tweakable block cipher What is the name of the mode in which we simply change the tweak for each block without the need for complex chaining modes? Is this mode secure?

Are there any other recommended modes for native tweakable block cipher like Threefish?
Many people want a "seekable cipher", which implies that they can't use chaining modes.(a) (b)
So far I've seen 3 ways to build such a cipher:


XTS: "XEX-based tweaked-codebook mode with ciphertext stealing (XTS)" is used in most modern "full-disk encryption" systems. (c)
CTR: "Counter mode (CTR)" (d)
OCB "Offset Codebook Mode (OCB)" (e)
