LESSONS LEARNT

1. Carrying out a separate G17 design approval /

appraisal for the preheater itself is

meaningless

2. NGN Comments. Rectified by NGN on behalf of

Bruest prior to commissioning:

i. The heat exchanger is designed as a pressure vessel (not as a pipe). The appropriate maintenance of a pressure vessel will need to be carried out by NGN

ii. Metal on metal pipe clips will not be used in future

iii. Cable terminations to be checked by Bruest before units are dispatched

iv. Where multi-core cables are used, all cores will serve a purpose. Cables with excess numbers of cores will not be specified

v. If electrical equipment is not intended to be sited in a hazardous area, it shall not be specified as if it was to be sited in a hazardous area

3. Consider programme risks of potential

obstructions underground when constructing

new bases
