Problems solved by technology

Conventionally there are two ways to go about it - let the uppermost layer make the decision about which PCB to use (but if it fails, it may take time to get another PCB to operate) or have a complex process running between the PCB's processors Algorithms, such as tokens between them, but there is a cost to developing such an algorithm, given that processors may have limited computing power

[0028] first reference Figure 4 , assuming that the software load for "electronic access" and "calculation" with respect to devices 1, 2 and 3 is greater than the processing power or capabilities of processor PA, but for "electronic access" with respect to devices 1, 2 and 3 and with respect to The software load of the "calculations" of the means 4, 5 and 6 is within the processing capabilities of the processor PA. Also, the software load for "electronic access" with respect to devices 4, 5 and 6 and for "computation" with respect to devices 1, 2 and 3 is within the processing capability or capabilities of the processor PB. Thus, processor PA performs "electronic access" with respect to devices 1, 2 and 3 and "computation" with respect to devi...

Abstract

A subsea electronics module comprises a plurality of processors (PA, PB) for controlling operations in a subsea hydrocarbon extraction well, the processors being coupled to a data highway (7) and there being distributed software in the module for controlling the processors so that the function of at least one of the processors may be carried out at least in part by at least one of the other processors.

Description

technical field [0001] The invention relates to subsea electronic modules. Background technique [0002] A typical configuration of an offshore oil or gas well includes an uppermost Master Control Station (MCS) with subsea control equipment installed on the seabed. MCS provides an interface for operators through subsea equipment, and displays the current status and sensor information of various parts of the equipment, enabling operators to control the entire subsea system. The MCS is connected to the subsea control module (SCM), which is installed on the tree on the seabed and controls all subsea control processes, providing hydraulic transmission to drive valves installed on the tree and at the wellhead. It also receives process instrumentation signals from sensors installed on the tree and at the wellhead. These signals are received and processed in an electronics module (SEM) housed within the SCM, and the resulting data is then transferred to the MCS. [0003] In earl...
