lang=EN-US> If for any reason, an automated control function fails or the
connectivity between a 3<sup>rd</sup> party app and the RigOS is lost, the
RigOS applies a series of actions to put the drilling machines in a state that
is safe for the current operation. This state lasts for at least a few tens of
second in order to leave time for the human operator to regain control of the
situation even though his situation awareness may have been low. In the context
of DWIS, the only addressed SMM functions are those linked to the protection of
the drilling process. i.e., SMM functions that deal with the protection of the
drilling machines are outside the scope of DWIS.</span></p>

</span></span><b><span lang=EN-US>Fault, Detection, Isolation and Recovery
(FDIR):</span></b><span lang=EN-US> If a drilling process incident occurs,
it is important to respond as quickly as possible. FDIR functions monitor
continuously the process and are capable of detecting when an abnormal
situation has started. After detection, the FDIR function proceeds with an
immediate response to keep the process as safe as possible. Then after
identification of the cause of the dysfunction, it applies procedures to
isolate the problem. Finally, when isolation has been successful, it applies
procedures to recover from the problem and get ready to resume the original
normal command. FDIR functions apply when automated control functions are
active, but also when human operators control the machines. A failure of the
isolation or recovery procedures may trigger SMM functions. In the context of
DWIS, only FDIR functionalities that concern the drilling process are addressed.
In other words, DWIS does not interfere with FDIR functionalities that protect
the drilling machines. FDIR is a subfield of </span><span lang=DE><a

combines the safe operating envelopes for the drilling process with the safe
operating limits that protect the drilling machines. SOE functions apply for
both human operator and automated function commands. It is not in the scope of
DWIS to address SOE functionalities concerning the protection of the drilling
machines.</span></p>
