American Midstream Partners LP has acquired a 66.7% interest in the 100-mile Okeanos natural gas gathering system in the Gulf of Mexico from its general partner, part of bundle of deals in which it paid $225 million (see Daily GPI, April 26). The Denver-based partnership, financed by ArcLight Capital Partners LP, had said it purchased interests in offshore and onshore infrastructure, including the Destin gas pipeline, the Tri-States and Wilprise natural gas liquids pipelines. The Okeanos pipe, with 1 Bcf/d of total capacity, connects two platforms and one lateral, terminating at the Destin Main Pass 260 platform in Mississippi Canyon blocks. Enbridge Inc. is the minority interest holder.
