Potable and Demineralised Water for Gas Plant

One of Australia’s leading Oil and Gas providers reached out to MAK Water with a unique UV disinfection replacement project for an offshore gas production platform. MAK Water was tasked with delivering a new UV disinfection solution in an existing area with very limited space requiring out-of-the-box thinking in regard to installation and on-going serviceability. MAK Water designed and manufactured a reliable solution to disinfect the potable water supply in the potable plant room, replacing a very worse-for-wear UV system installed in 1993 which was failing. We worked closely with the client to design a fit for purpose, long-term solution, compliant with the Australian Drinking Water Guidelines (ADWG) and rigid offshore engineering specifications.

An oil & gas operation was rehabilitating a decommissioned site on a remote island off the northern Western Australian coast. They required fresh water for the irrigation of planted seedlings to help them establish and restore the environment. However, the arid island had no natural fresh water source, other than sporadic rainfall which was not sufficient to support the rehabilitation works. The native seedlings don’t require irrigation once they’ve established their roots, thus, this customer’s need for a seawater desalination plant was only temporary, making the purchase a desalination plant an undesirable capital outlay. Compounding factors in this challenge were the logistics of getting the plant to the very remote site, and the island’s status as a Class C nature reserve, requiring strict quarantine compliance and operational reliability with minimal risk to the environment.

A contractor for a major Oil & Gas plant expansion project in the northwest of Western Australia had two 260kL water tanks supplying potable water to the construction facilities. MAK Water was selected to design and manufacture a reliable solution to maintain adequate disinfection levels in the tanks and pump the water through the distribution network. MAK Water worked closely with the client to design a fit for purpose, custom Sodium Hypochlorite Dosing – Recirculated (SHDR) plant to continuously maintain a specified chlorine level in the water so that it safely complies with the Australian Drinking Water Guidelines (ADWG). The system is also flexible; able to operate on one tank while the other one is being refurbished.

An EPC contractor was engaged to deliver a gas processing facility for one of the largest gas fields ever discovered onshore in Australia. The project required ultra-pure demineralised water for makeup water in gas conditioning as well as potable water for the site. MAK Water worked collaboratively with the EPC contractor through the tender phase to value engineer a bespoke solution and was subsequently selected to deliver the plant.

A remote natural gas, condensate and oil processing facility in north-west Western Australia had an ageing sewage treatment plant (STP) requiring replacement, the operator contacted MAK Water. We took our client through a thorough engineering design process where we had to account for the challenges of the extreme remote location, 20-year design life in a cyclone-prone, corrosive marine environment (AS4312, Category 5), and compliance with our client’s exacting engineering standards and specifications MAK Water manufactured, commissioned and continues to visit the sewage treatment plant monthly to keep the plant operating optimally.

A Gas Plant in Karratha – home to one of the most advanced, integrated gas production systems in the world, where LNG, domestic gas, condensate and LPG is produced, approached MAK Water to assist with a new demineralised water plant. The water treatment plant was a part of a US$5 billion life extension program, to extend the life of the asset by 20 years. MAK Water has been a long term and trusted supplier to the client; working cooperatively with their contractor during the budgeting phase, MAK Water was awarded the contract to design, manufacture, supply and commission the new demineralised water plant.
