Last year was a huge year for initial public offerings as 222 companies went public. Master limited partnerships proved to be no exception, and the 20 MLP IPOs of 2013 was good for an all-time record.

This year has proven to be quite different, however, as MLP IPOs have slowed to a trickle. In this video, Fool.com contributor Aimee Duffy talks to Tyler Crowe about the IPO of Cypress Energy Partners (CELP), and possible MLPs in the works from Antero Resources (AR 1.93%), and PBF Energy (PBF -0.63%). She also points out that though midstream IPO activity has slowed down, the industry itself remains hot thanks to recent moves from companies like Phillips 66 (PSX -0.99%).
