3.4.8 Drain and vent Nozzles for drain and vent are located on
the headers.
3.4.9 Skid The WHRU have included support structure for single
lift to provide easy and fast installation as well as adaptation to
the compressor module. The skid frame material will be painted
carbon steel S355 J2. Painting and surface treatment will be
according to customer specification or NORSOK system 1. 100% MPE
and 100% visual examination of all main welds will be included.
Material certificates will be according to EN 10204-3.1. The
suggested WHRU arrangement integrated into the Nohoch compressor
module is illustrated conceptually in red in Figure 1.
Figure 1: The proposed WHRU incl interconnecting ducting and
extra support steel shown integrated in the Nohoch compressor
module.
