Subsea blowout preventers (BOPs) are installed on the seabed, with their upper end connected to the riser system and their lower end linked to the subsea wellhead or subsea tree. They constitute the most critical well-control equipment in deepwater drilling operations. The mainstream subsea BOPs used internationally operate at a working pressure of 15,000 psi (103.5 MPa), with maximum operating pressures reaching up to 20,000 psi (153.5 MPa), and can accommodate water depths exceeding 3,000 meters. A typical subsea BOP system comprises a lower riser manifold assembly (LMRP), a lower BOP stack (LBOP), and a control system.
The auxiliary high-pressure piston accumulator system enables ROV (remotely operated vehicle) intervention systems to meet the regulatory requirement of a minimum shut‑down time of 45 seconds at the maximum allowable pressure. As requirements for controlling secondary blowout preventer stacks become increasingly stringent, users can rely on our proven, code‑compliant ROV intervention approach, employing the SCHWERLL auxiliary rapid‑intervention accumulator system.
Our solution offers a modular, standalone subsea energy storage system that can be rapidly and easily integrated to support emergency blowout preventer (BOP) interventions.
Anyone who has the opportunity  ROV  All can be achieved via hydraulic flywires and industry-standard…  17H High‑flow hot spools connect the auxiliary accumulator system to the blowout preventer stack. The ROV‑operable paddle valves on the control panel enable convenient, direct operation, and the system can operate at an optional pressure of 5,000 psi.  and  3000psi or  3000psi and  3000psi and  Provides high flow (100 gal/min) at 1500 psi.  It controls fluid flow and is equipped with dual pressure regulators. For larger volumes, an auxiliary headset module can be integrated into the system. Designed to meet the requirements of blowout preventer intervention and secondary control, the system is specifically engineered for long-term subsea deployment. Seaville also provides maintenance services and certifications for specialized products, ensuring that the equipment is ready for emergency use at all times.
