Our team installed the monitoring systems for the rig lifting operations on board the platform. 36 Wireless 4K UltraHD CCTV Cameras powered by 12VDC 24Ah weatherproof cyclic batteries
Considering the installation in areas with difficult access to electricity, an industrial wireless CCTV system in the 2.4 Ghz band was chosen with 36 CCTV cameras in various locations, of which 8 cameras acted as repeaters. The system operated continuously for 60 hours from start-up, providing more than enough time compared to the 24 hours expected for the lowering and then raising of the tower in Constanta.
The system was installed inside and outside the drilling derrick in the anchoring areas of the hydraulic cylinders that took over its weight during the horizontalization process. A total weight of 850 Tons was launched with precision within a period of 24 hours.
Fiind o operatiune cu risc ridicat echipa Transocean nu a permis nici unui membru al echipajului care nu a fost implicat in operatiune accesul la bord. Iar personalul esential de la bord nu a avut permisiunea de a lucra la exterior in timpul operatiunii, astfel totul a fost realizat prin monitorizare video de precizie cu 40 camere FullHD si UltraHD . Provocarea a venit din partea materiarului constructiv al platformei, metal de 5-15 mm grosime, iar penetrarea wireless a avut de suferi in unele locuri – in acest sens au fost instalate 13 repetitoare de semnal, 4 NVR-uri Ultra HD , iar in punctele cheie camerele au avut si functia de redare si inregistrare audio.
Intreagul stream video al celor 36 de camere a putut fi vizualizat live in cabina de comanda de unde echipa de control a realizat cu succes operatiunea in Cartagena.
La sosirea in Portul Constanta, acelasi procedeu a fost repetat invers de aceasta data , turla de foraj fiind ridicata si readusa la pozitia verticala initiala. In premiera acelasi stream video a fost transmis live si catre sediile TransOcean din Stavanger – Norvegia si Houston Texas SUA.
Simultan cu cele 36 de camere doua drone performate cu zoom optic 30x au stat in aer 24h iar operatorii dronelor au stat in stransa legatura radio cu echipa de control de la bord – afisand pe un display secundar cu transmisie video live din drona punctele de interes cerute in timpul ridicarii turlei pe pozitie.
Aceasta operatiune a fost necesara pentru ca platforma sa poata trece pe sub cele trei poduri din stramtoarea Bosfor cu o inaltime de 67 metri. Platforma a avut 64 metri cu turla lasata la orizontala in timpul traversarii.
