SenTURIAN Large-Bore Subsea Landing String Electrohydraulic Operating System

Overview Library

Quickly operate subsea equipment with less risk and reduced rig-up time

The compact SenTURIAN large-bore 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 arctic conditions, ultradeep water, and HPHT.

Subsea safety first with SIL 2 certification

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).
