Operations from floating vessels
The compact SenTURIAN subsea landing string electrohydraulic operating system features a flexible, modular design and simple operation, and provides up to 50% rig-time savings during handling. Designed to operate from floating vessels, this highly adaptable system allows customization and upgrades to meet project-specific requirements. The system operates in all subsea applications, including deep water, high pressure, and high temperature.
Reliability benchmark
The SenTURIAN system is the world's first in-riser system designed and certified in accordance with IEC 61508 SIL 2 reliability specifications for safety-related systems. This design approach sets a new industry benchmark for reliability of in-riser electrohydraulic operating systems.
Modular and flexible design
The modular design of the SenTURIAN system enables compliance with ISO 13628-7 standards by providing electronic redundancy and pressure readout for each subsea function. The electronic redundancy feature includes fully redundant electric control. The pressure readout provides multiple pressure transmitter and flowmeter functionality, allowing triple-point verification of valve actuation (i.e., electrical contact, pressure reading, and flow measurement).
