SQAExpected benefits of autonomous technology

• A survey related to autonomous shipping by Nautilus Federation

– almost 900 maritime professionals from 12 different countries

were participated.

• More than 60% consider technology could be used to improve safety and automation offers the potential to deliver improved operational performance.

• Benefits to use new equipment and systems to:

– reduce workloads,

– ease administrative burdens,

– eliminate dirty and dangerous work in enclosed spaces, and

– assist with predictive and preventive maintenance.


“If higher automation releases ships’ staff to monitor more

effectively what is happening aboard their vessels, that

should be an advantage since crews on many types of ship

are overworked and tired, making poor decisions and

accidents more likely.”

SQASoftware Functional Safety


“Functional safety, defined as the absence of unacceptable risks due to

hazards caused by the malfunction behavior of electric or electronic systems,

is quickly becoming a key factor in the development of modern vehicles.”

by FEV Motorentechnik GmbH

Functional Safety

SQASafety and Security


• Safety

– The prevention of accidents which may or may not

involve human agents, but are in any case not

intentional.

– Safety can also refer to protecting against things like

users making dumb mistakes.

– performing dangerous options using computer, we

prompt the user with a confirmation box, to increase

overall safety.

• Security

– The prevention of malicious activities by human such as

mugging, burglary, robbery, terrorist activities.

– The prevention of unauthorized actions such as changing

settings for prevented and/or not allowed data.

• Guidelines on cyber risk management IMO

– Led by BIMCO Baltic and International Maritime Council (2017)

• Guidelines on Cyber Security Onboard Ships

Functional Safety

SQASoftware safety opportunity in Autonomous vessels


• Terminologies

– Smart ships, ships' connectivity, remote ships, and digital twin etc.

• Summary of IMO MSC's discussions on autonomous ships

The scoping exercise of "autonomous ship" should include:

– the full range of human element factors within different levels of

autonomy for both shipboard and shore-based personnel;

– the reliability, robustness, resiliency and redundancy of the underlying

technical, communications, software and engineering systems;

– consideration of conducting a Formal Safety Assessment or gap

analysis as to the safety, technical, human element and operational

aspects of autonomous remotely controlled or unmanned ships.

Functional Safety

SQAConcluding remarks

• Autonomy will come sooner if providing at a low cost

• Software will become a growing feature more and more

- Software quality and Software functional safety as part of overall

maritime safety

• Proactive and preemptive actions are needed

– To improve the level of safety and efficiency in maritime area

– To improve the seafarers’ work life
