Due to its low weight, and small foot print coupled to its modular design the CiBAS WHRU is ideal for retrofitting onto existing Platforms or FPSOs to replace a Traditional WHRU or to where a gas turbine is available to increase the facilities process heat supply
Case Study
The client when planning to tie back a number of additional fields that it had discovered and developed to an already operating offshore processing facility. The Client had calculated that the additional product flow through the processing plant would exceed the current process heat rising capability.
However on the facility there was a gas turbine driven compressor set that was at that time running in open cycle mode which could be utilised to recover heat from providing that a WHRU could be installed into the space that was taken up by the silencer, stack and support steel-work.
Having taken the process data and the projects requirements from the client CiTECH calculated that there was sufficient space for a CiBAS Unit to be installed and only minimal reinforcing work to the existing structure was required to support the unit.The early calculations also showed that the dry weight of the unit would be in the region of 50 tonnes. As a single lift this was outside of the facilities crane capabilities of 15 tonnes at that reach, therefore the Client would be looking at hiring a heavy lift crane if the unit was to be installed as a single lift. The cost of hiring a crane with this capability was high coupled with the unpredictable weather conditions that frequented the area made planning the lift difficult and as a result cost were predicted to rise.
