It would lead to fewer safety regulations b. It would have no impact on job roles c. It may lead to job displacement but increase technical positions ✓ d. It would create more jobs in traditional roles The correct answer is: It may lead to job displacement but increase technical positions Question 111 Correct Mark 1 out of 1 Flag question How does valve lift percentage relate to ow control in a valve? a. It is always proportional b. It depends on the actuator type c. It varies with valve characteristics ✓ d. It remains constant The correct answer is: It varies with valve characteristics Question 112 Correct Mark 1 out of 1 Flag question How is "Degree Three" characterized in the IMO Levels of Automation? a. Partially autonomous ship b. Ship with decision support but no automation c. Remotely controlled ship with no seafarers on board ✓ d. Fully autonomous ship The correct answer is: Remotely controlled ship with no seafarers on board Question 113 Correct Mark 1 out of 1 Flag question How many degrees of autonomy are identi ed in the IMO scoping exercise for automation? a. Five b. Three c. Four ✓ d. Two The correct answer is: Four Question 114 Correct Mark 1 out of 1 Flag question How might the absence of seafarers on board in Degree Three impact search and rescue operations? a. It would improve the e ciency of search operations b. It would complicate rescue operations as no crew is available ✓ c. It would have no impact on rescue operations d. It would require remote systems to handle rescues The correct answer is: It would complicate rescue operations as no crew is available Question 115 Correct Mark 1 out of 1 Flag question How might the role of remote operators in Degree Two in uence shipboard safety protocols? a. Remote operators can increase e ciency, making safety protocols redundant b. Remote operators must be integrated into existing safety protocols ✓ c. Remote operators are not accountable for safety protocols d. Safety protocols would shift to focus more on the crew than the remote operators The correct answer is: Remote operators must be integrated into existing safety protocols Question 116 Incorrect Mark 0 out of 1 Flag question How would a seafarer on a remotely controlled ship under Degree Two intervene in a system malfunction? a. By switching to a higher degree of automation b. By shutting down the system entirely c. By manually overriding the automated processes d. By contacting the remote operator for instructions × The correct answer is: By manually overriding the automated processes Question 117 Correct Mark 1 out of 1 Flag question How would you address non-linear behavior in shipboard control systems? a. By manually adjusting the control settings frequently b. By applying control systems with exible response parameters ✓ c. By reducing the number of sensors in the control system d. By using xed control actions to avoid system instability The correct answer is: By applying control systems with exible response parameters Question 118 Correct Mark 1 out of 1 Flag question How would you apply Degree Three automation in a scenario where weather conditions become unsafe? a. Use manual controls for navigation b. Increase the degree of human oversight c. Inform the remote control operator to take over ✓ d. Allow the ship’s autonomous systems to handle the situation The correct answer is: Inform the remote control operator to take over Finish review ◄ SELF TEST - BSMARE SI-BRAVO NSA Jump to...
