BPZ Energy, an independent oil and gas exploration and production company, announced that the hull tower for the CX-15 platform was successfully floated off the transport vessel, uprighted and ballasted. Subsequently, the topside facility was also successfully mated to the hull tower.
The CX-15 platform is now anchored at the West Corvina field location, one mile south of the existing CX-11 platform.
Welding and other miscellaneous activities are underway and will take approximately two weeks. The Petrex-28 drilling rig, which has been inspected and accepted for work, will then be mobilized to the CX-15 platform. It is expected that the necessary environmental permit required to conduct drilling operations from the CX-15 platform will be received from the Peruvian authorities before the drilling rig is mobilized. The Company expects to spud the first well of the CX-15 drilling campaign in late October.
The CX-15 platform was safely completed and successfully delivered to BPZ Energy at Wison Offshore & Marine’s Nantong, China, fabrication facility in a record 11 months from contract signature and without a single lost time incident. Wison’s scope included the engineering, procurement and construction of the facility’s 2,500 ton Buoyant Tower hull and 1,500 ton topsides facility. This project represents not only the first use of the design, but also the first implementation of Wison’s integrated international delivery model including members from the company’s three operation centers Inc. located in Shanghai and Nantong, China, and Houston, Texas, USA.
The Buoyant Tower hull for the facility was designed and engineered through a joint venture between Wison affiliate, Horton Wison Deepwater, and GMC Limited and consists of four, ring-stiffened connected cylindrical tubes or “cells” with one central suction pile. Each cell measures 8.4 meters in diameter and 60.1 meters long, with a total hull length, including suction pile, of 69.9 meters. This design, which is similar to proven cell spar technology, was a key enabler for the project due to the fact that it will not require a derrick barge for installation as it is located in a region with minimal resident offshore construction vessels.
