The Sagar Jyoti (BDR-02) oil rig, built by Coromandel Deepwater Constructions (the same company that built the Kaizen Pioneer), is planned to be the first Bhahsani-Vangan joint oil rig and the first joint program between the two in over 35 years. The rig is built upon the base of an old Bijoyite project bearing the same name, which was a hybrid pontoon/spar/sea star layout, revolutionary at its time (around the late 1990s). The project, though, was shelved for unknown reasons, but was unshelved recently as part of the Future Industrialization megaproject. According to the official blueprint given by Coromandel Deepwater Constructions, the Sagar Jyoti will mount 1 CB-400 and 2 CB-300 offshore cranes to haul heavy supplies across the rig and onto transport vessels. The rig also features a 55-meter-tall central drilling derrick, along with a single large-diameter central riser pipe extending from the bottom of the spar hull directly onto the seafloor, where heavy hydraulic tensioners support it. Also, just like the Kaizen Pioneer, it features a cantilevered, structured steel octagonal helipad with distinct green safety trimming. The rig is planned to be moored to the seafloor using 8-point heavy catenary chains and wire rope anchoring networks that extend diagonally from the outrigger pontoons to deep-sea anchor templates. It will also be equipped with four auxiliary thrusters to maintain pinpoint station-keeping during active drilling missions. Additionally, the hybrid SeaStar hull footprint reduces rolling and pitching by 40% compared to traditional rectangular semi-submersibles. To accommodate the 120 crew members who will operate her, Sagar Jyoti has a multi-story modular habit block with crew comforts, including a cafeteria, clinic, and even a gym. Sagar Jyoti also has a radome radar to avoid collisions with heavy maritime traffic from the Alaksandrian Estuary, Mouth of Alaksandria, and the Alfours Sea. Additionally, in the event of an emergency, Sagar Jyoti is equipped with high-visibility, hyperbuoyant free-fall lifeboat capsules with a 200% survival-craft capacity. When she is not used for drilling, Sagar Jyoti will have four ropes that drive into the ocean to accommodate exploration missions and recreational swimming. Additional systems include three parallel three-phase separator trains, a 45-meter-tall diagonal flare boom, and a color-coded pipe network.
