14. Master Control Station
The MCS is a 19” rack mounted system that provides control of multiple subsea wells.
It provides the operator interface as well as control logic, interlocks and event logging.
The standard system offers dual PC redundancy to ensure maximum uptime.
Communication with the subsea equipment is based on Vetco Gray’s market leading high speed powerline signalling technology.

22. Version Control
It is common for multiple engineers to be working on the different modules of the same application at any given time.
Applications are usually developed in separate modules for different functionality.
Ensuring that the engineer is using the most up-to-date version is essential.
Version control allows engineers to work on the same application at the same time without worry that it is being changed by another engineer.
Version control allows you to role back to previous versions of the application, extremely useful if a bug gets programmed into the version.

23. Code Reviews
When working as part of a team of software engineers it is important to ensure that regular code reviews are carried out.
This not only re-clarifies the goal of the project but also helps other people understand what you are trying to achieve.
It also helps to highlight possible bugs which may be in the code.
It can also highlight the possibilities for optimisation.

24. Log Books Your log book is your best friend.
It is essential when you need to refer back to a common problem.
Log books are commonly used as a method of proving your knowledge, they can be used to become a chartered engineer.
Log books can also be used when it comes to patents and for proving intellectual property.

26. Small Change Big Difference
A change in your section of the application may inadvertently effect another part of the application.
Always use a method of version control when developing software. Often you will be working a teams and developing different parts of the same application.
If developing safety critical systems ensure the use of interlocks.
Design your system so that it can only be operated one way.
