For over 40 years, Russian-Vietnamese Joint Venture «Vietsovpetro» has been performing its operation in the shelf area of the Socialist Republic of Vietnam. The Company possesses a large number of technological vessels and mobile offshore drilling units. Mobile offshore drilling fleet consists of five self-elevating mobile offshore drilling units (jack-up rigs): Tam Dao-01, Tam Dao-02, Tam Dao-03, Tam Dao-05 and Cuu Long. To ensure the absolute safety while operating the drilling units and to comply with the requirements of the Supervising Register of Shipping, the scheduled and major repairs of jack-up rigs are performed consistently, including the repairs in a dry dock. In 2023, the dry-docking was scheduled for Tam Dao-01 jack-up rig. However, the massive size of the “rig” and existing Vietnam dock infrastructure allows performing such operations for the mobile offshore rigs only at Qung Quat shipyard, which is located in the Central Vietnam, 400 sea miles away from Vietsovpetro production facility. Considering an actively developing and steadily increasing fleet that operates at Vietnam offshore, Dung Quat dry dock is highly demanded and, consequently, very busy. The distance and limited availability of Dung Quat dock led to the fact, that Tam Dao-01 repair operations required not only high level of Vietsovpetro competence in terms of naval operations, but also elaborating the unique solutions for repair-docking the “rig” under the conditions when the dry dock access is limited. As the result, Tam Dao-01 has been safely transported and docked for repair with due dispatch.
