摘要

On the well JACINTO 01 (Angola), by 1632 m of water depth, while pulling out the BOP stack to check a malfunction during the pressure tests of these BOP, before starting the 17"1/2 phase, the breaking of the drilling line, while the BOP was at 620 m, caused the fall of the BOP and about 600 m of riser. The top drive felt and passed through the rotary table and, some other parts (bails, balls back-up wrench, elevator, riser running tool and few other metal debris) felt on the seabed with the BOP and the riser. The vessel returned to Cape Town for repair, inspections and preparation of the BOP recovery. In accordance with specialized service companies, we decided to try to recover it and we prepared tools: For Example: => Lasso tool, Pride design => Modified riser running tools => Use of excavators => Special jet subs with different designs... The BOP recovery operation program, that will be developed in the presentation, is: 1- Installation of a protection cage on well head 2- Recovery of metal debris around BOP 3-Recovery of laying riser joints by using jet tools, lasso tools... 4-Excavation around BOp using excavators, jet tools... 5- Cutting first riser 6- Fishing BOP using two strings in the same time... The operation ended in success on the 26/01/2000, the entire BOP and the risers has been recovered.
