Singapore Sling

Singapore is the Asia Pacific hub for ExxonMobil’s downstream and chemicals businesses. The SPT project was instigated by ExxonMobil as an extension of its existing presence with a 605,000 barrel per day refinery. When completed, the petrochemical complex became the largest project owned and operated by ExxonMobil.

The Singapore Parallel Train (SPT) project is an integrated petrochemicals project within the refinery and chemical hub of Jurong Island in Singapore.

In January 2006 Foster Wheeler was awarded the contract to work on the early phase of the project including the initial feasibility and FEED. In October 2017 the final investment decision was made on the $4 billion project and the joint venture partnership of Foster Wheeler and Worley Parsons were awarded the engineering, procurement and construction (EPC) of new process units and their integration into the existing facility.

The construction of SPT was carried out within an existing ‘live’ petrochemical complex which brought numerous restrictions for heavy lifting and transport operations.

To undertake the installation of all the major process vessels it was proposed to use the very first Terex Demag CC8800-1 Twin Boom, a 3,200te capacity crawler crane, on its inaugural job. The crane was assembled in one location, within the plant on a purpose built concrete foundation. From here it lifted columns weighing over 300 tonnes at radii of up to 80 metres.

Kilometres of modularised pipe racks (PARS) were fabricated in Batam, Malaysia, and then barged across to Jurong Island, where they were transported on SPMT into the plant and installed using a combination of crawler and mobile telescopic cranes.

With monsoon rain storms and lightning strikes a regular occurrence during the installation period, planning and coordinating the barging, transport, storage and lifting of the equipment was key to the overall success of this project.

Techlift’s scope of work included the following activities:

  • Onsite management of clients team of heavy lift engineers & supervision
  • Review and final sign off all heavy lift and transport operations
  • Focal point for coordination with base plant operations
  • Carry out project update presentations to ExxonMobil management
