CAPS has won the compressor contract for Woodside Petroleum's North West Shelf project, at its $5 billion North Rankin B Platform.
According to the compressor company, the North Rankin B project is similar to the one carried out for Woodside’s North Rankin A Platform nearly a decade again.
“As part of Woodside’s continuous improvement and ‘lessons learnt’ policy, CAPS incorporated the feedback from Woodside and developed a package that contains significant design improvements,” Alan Kemp, the senior project engineer forCAPS Australia said.
Local content was a major focus for the company as it designed and built the package, with the majority of parts being sourced in Australia.
CAPS will provide three 160 kW Ingersoll Rand rotary screw air compressors along with two air dryers and four filters that have been designed and built specifically to meet Woodside’s need for a 30 year life cycle, it stated.
In designing the package, CAPS had to factor in the extreme climatic conditions of Western Australia's North West Shelf, both on sea and land.
Because of these issues it had to build custom features into the compressors to handle the corrosive environment surrounding the platform.
CAPS stated that "the unit’s oil and air coolers will be purpose built with unique anodised surfaces and the internal oil handling system will be made of duplex and super duplex stainless steels. The entire external enclosure will be made from passivated 316 stainless steel. In consideration of the location and ecology, the coolant, lubricant and drying media chosen for use in the machinery are non-hazardous and eco-friendly.
“To ensure maximum uptime and reliability, the package will have a centralised state-of-the-art programmable logic controller (PLC) which will oversee the three compressors and two dryers, linked to a range of data monitoring and analysis instruments. The PLC will include emergency power supplies to ensure minimal disruption even in the worst cases,” Kemp added.
To make installation easier, the company also created a special lifting beam to provide for safer and easier handling.
