Situation

Our client required an upgrade to the existing power generation facility to support increased demand for industrial and domestic use. Located in a remote, offshore environment, the logistics challenges were presented.

Solution

Aerison were engaged as the primary contractor to deliver engineering and design, fabrication and installation works for the following scope items:

• The acoustically treated and fire rated generator halls to house four (4) Wartsila W6L32 gensets allowing for future removal/installation of any of the gensets.
• Ventilation systems and engine exhaust systems including roof mounted mufflers.
• Structural, mechanical, piping, electrical and instrumentation works.

Particular Features:

• The enclosure was designed to provide a four-hour fire rating for all wall partitions

Project Highlights:

• Complete building, equipment and components were engineered and designed to be suitable for containerised transport.
• Complete project was delivered from Australia for assembly on Christmas Island.
• Equipment and components designed to withstand the harsh coastal environment conditions of Christmas Island.
• Individual generator halls supplied with filtered ventilation air and the electrical control room temperature-controlled air conditioning.
• Generator enclosure designed to meet strict noise requirements of 85 dB(A) sound pressure at 1m.

Outcome

• Design and construction activities were delivered safely with no reportable incidents.
• Reduced onsite construction activity through pre-assembly and modular build methods. Despite inclement weather conditions, the project was completed ahead of schedule within the allocated cost.
