Embodiment Construction

[0016] Figure 1 schematically shows the above configuration of the control system of a hydrocarbon extraction well facility incorporating the present invention. Reference numeral 1 designates the MCS; reference numeral 2 designates the umbilical; reference numeral 3 designates the SCM; reference numeral 4 designates the SEM; reference numeral 5 designates the tree;

[0017] The SCM is a self-contained sealed unit with a steel sleeve and metal base plate, which is secured to the tree 5 by a series of bolts. The SEM 4 itself is a heavy metal unit, firmly integrated inside the SCM 3.

[0018] However, contrary to what has been described above, the sensor group 6 does not include the above-mentioned dedicated vibration sensor. In contrast, embodiments of the present invention require the installation of an integrated circuit (IC) 7 that incorporates a three-axis vibration sensor on a PCB 8 mounted into the SEM 4 . The IC 7 is mechanically affixed to the PCB 8 by a sufficiently s...

Abstract

An electronics module (4) for use subsea is provided with a vibration sensor (7) on a printed circuit board (8) in the module, for sensing vibration of the module. The module is typically a subsea electronics module for use in a control system for a subsea hydrocarbon extraction well facility.

Description

technical field [0001] The present invention relates to electronic modules for subsea use, for example in control systems for hydrocarbon extraction well installations. Background technique [0002] In offshore oil and gas production control systems, many devices are assembled on trees, installed on the seabed. The main equipment of a typical system configuration includes: [0003] Master Control Station (MCS), which provides the operator interface with subsea equipment and displays the current status of various subsurface equipment, subsea valves and sensor information, allowing the operator to control the system; [0004] an umbilical cable that connects the MCS to equipment installed on the seabed and incorporates a communication link that conveys control signals to the subsurface equipment and status information of the subsurface equipment to the MCS; [0005] Subsea Control Module (SCM), which receives commands from the MCS and controls all subsea processes, provides ...
