In the years ended December 31, 2019 and 2018, we made an aggregate cash contribution of $74 million and $91 million, respectively, to Orion Holdings (Cayman) Limited (together with its subsidiary, “Orion”), a Cayman Islands company that, through its wholly owned subsidiary, owns the harsh environment floater Transocean Norge. At December 31, 2019 and 2018, the aggregate carrying amount of our investment in Orion, representing a 33.0 percent ownership interest, was $164 million and $91 million, respectively, recorded in other assets using the equity method of accounting.

Related party transactions—We engage in certain related party transactions with Orion under a management services agreement for the operation and maintenance of the harsh environment floater Transocean Norge and a shipyard care agreement for the construction of the rig. In the year ended December 31, 2019, we received an aggregate cash payment of $96 million, primarily related to the commissioning, preparation and mobilization of Transocean Norge under the shipyard care agreement. We also lease the rig under a short-term bareboat charter agreement, which is now expected to expire in late 2020. In the year ended December 31, 2019, we recognized rent expense of $8 million, recorded in operating and maintenance costs, and made an aggregate cash payment of $6 million under the bareboat charter agreement.
