5.5.1 <strong>Ethical</strong> <strong>issues</strong><br />
Pip<strong>in</strong>g <strong>and</strong> equipment<br />
Any <strong>design</strong> process <strong>for</strong> pip<strong>in</strong>g <strong>and</strong> equipment gives rice to ethical <strong>issues</strong>,<br />
particularly those perta<strong>in</strong><strong>in</strong>g to safety. These ethical <strong>issues</strong> are discussed <strong>in</strong> more<br />
detail <strong>in</strong> section 5.4, I will review them here shortly.<br />
Eng<strong>in</strong>eers believe that <strong>design</strong><strong>in</strong>g accord<strong>in</strong>g to legislation <strong>and</strong> codes leads to<br />
safe <strong>in</strong>stallations. Legislation <strong>and</strong> codes prescribe a lot, but do not cover all<br />
choices regard<strong>in</strong>g safety.<br />
At the start of the <strong>design</strong> process, a choice has to be made between us<strong>in</strong>g the<br />
different codes that the pert<strong>in</strong>ent legislation permits. Some choices regard<strong>in</strong>g<br />
safety are not specified <strong>in</strong> a code <strong>and</strong> have to be made by the eng<strong>in</strong>eers <strong>and</strong> / or<br />
customer. For example, accident <strong>and</strong> load scenarios are not def<strong>in</strong>ed <strong>in</strong> European<br />
codes <strong>and</strong> legislation. Under the PED eng<strong>in</strong>eer<strong>in</strong>g companies are obliged to<br />
make a risk analysis of their <strong>design</strong> but what accident <strong>and</strong> load scenarios should<br />
be used are not specified.<br />
Accord<strong>in</strong>g to the eng<strong>in</strong>eers there is a difference between merely follow<strong>in</strong>g a<br />
code <strong>and</strong> follow<strong>in</strong>g that code well with<strong>in</strong> its limits. The Notified Body cannot<br />
reject <strong>design</strong>s that comply with legislation <strong>and</strong> codes but there is a difference <strong>in</strong><br />
safety between a <strong>design</strong> on the lower limits of a code or a <strong>design</strong> well with<strong>in</strong> its<br />
limits.<br />
There are also ethical <strong>issues</strong> related to the division of responsibility especially<br />
if the <strong>design</strong> is to be constructed by another company. Some details are not<br />
specified <strong>in</strong> a <strong>design</strong> because a construct<strong>in</strong>g company needs some freedom to<br />
decide what method to use <strong>for</strong> construction. This may tempt eng<strong>in</strong>eers not to<br />
specify any of the difficult details because the construction company will do this.<br />
The <strong>design</strong><strong>in</strong>g company might make a <strong>design</strong> that cannot be produced, or one<br />
that is only possible if employees at the build<strong>in</strong>g site run large risks.<br />
Another ethical issue that was raised by the eng<strong>in</strong>eers at the eng<strong>in</strong>eer<strong>in</strong>g<br />
company <strong>and</strong> the eng<strong>in</strong>eer from a Notified Body was that the level of knowledge<br />
regard<strong>in</strong>g <strong>design</strong><strong>in</strong>g safe <strong>in</strong>stallations with<strong>in</strong> chemical companies, eng<strong>in</strong>eer<strong>in</strong>g<br />
companies <strong>and</strong> the Notified Body was decreas<strong>in</strong>g. Chemical companies have<br />
outsourced most of their eng<strong>in</strong>eer<strong>in</strong>g work where once they had some<br />
experienced eng<strong>in</strong>eers work<strong>in</strong>g with<strong>in</strong> eng<strong>in</strong>eer<strong>in</strong>g departments. Eng<strong>in</strong>eer<strong>in</strong>g<br />
companies fired some of their very experienced senior eng<strong>in</strong>eers when the<br />
dem<strong>and</strong> <strong>for</strong> eng<strong>in</strong>eer<strong>in</strong>g work was low dur<strong>in</strong>g the n<strong>in</strong>eteen n<strong>in</strong>eties. The<br />
Stoomwezen has not been allowed to hire new eng<strong>in</strong>eers <strong>for</strong> some years <strong>and</strong><br />
now its experienced senior eng<strong>in</strong>eers are retir<strong>in</strong>g without the junior eng<strong>in</strong>eers<br />
hav<strong>in</strong>g ga<strong>in</strong>ed enough experience <strong>and</strong> knowledge to carry out their certify<strong>in</strong>g<br />
tasks at the same level as that of the eng<strong>in</strong>eers who have retired.<br />
