Provided sustainable green solutions for the world's largest biodiesel plant. Performance in past Neste job encouraged client to award Keller another job. Strong problem-solving attitude and technical capabilities overcame challenging soil properties.
Neste, a Finnish renewable energy company, invested S$2 billion in its expansion by building the world’s biggest biodiesel refinery in Tuas, Singapore. With excellent record from previous job done for the client, Keller was entrusted again due to our innovative and sustainable solutions.
Compared to previous Neste project in 2008, Keller faced the challenge of high variability in soil properties as the site, which was 118,300 m2 in area, was entirely reclaimed from sea. After extensive analysis, Keller proposed design and build solutions customised for the variable properties. This required four operations: pre-drilling through dense sands, stone column installation for clay layer, vibro compaction for looser sands and upper stone columns in the residual soil, with up to 160 manpower on site at its peak.
Keller’s innovative and cost-effective solution with low carbon footprint resonated with NESTE’s objectives and provided flexibility to foundation placement while design was still ongoing. Our expertise, capabilities and resources gained the client’s trust, resulting in over 10 years of relationship.
