Cypress, TX -- Tai Power, Taiwan’s state-owned Energy Company, needed a storage solution for their fuel at their Hsin-Ta Fossil Power Station in Kaohsiung Hsien, Taiwan. Gibsin Engineers LTD, a specialist company hired by TaiPower, determined that four 126m diameter concrete silos with an aluminum dome cover would fend off saltwater spray and typhoon winds.
In 2005, the Team of Geometrica Inc. from Houston, Texas; along with Triumstar International Co. Ltd. and Chien Yang Construction and Engineering Co. Ltd. (both from Taipei), won the bid to provide cost-efficient structures that met with TaiPower requirements.
From the start and through the whole project, the companies supported each other to deliver a seamless experience to Tai Power. Triumstar and Geometrica had over 10 years experience cooperating to build domes. Geometrica handled engineering, manufacturing and technical assistance during installation.
Being part of their expansion plans, Tai Power Company had the need to store their fuel material under cover at their Hsin-Ta Fossil Power Station in Kaohsiung Hsien, Taiwan. The state-owned company retained the specialist company Gibson Engineers LTD to draw up the plans and specifications that would encompass all emerging necessities for the coal storage.
Gibsin layout solution consisted of four 126m diameter concrete silos with internal automated stacker/ reclaimer system, and metal dome covers. Each unit would store 180,000 t of coal in a live pile for a total of 720,000 t.
Gibsin specified domes clad with aluminum sheeting and galvanized steel for the structure, as it would provide superior strength, flexibility in schedule, and because it used round tubular members (which preclude dust accumulation on the members), all for a more competitive price.
In mid-2005, the team consisting of Triumstar International Co. Ltd. of Taipei, Geometrica, Inc. of Houston, Texas, and Chien Yang Construction and Engineering Co. Ltd. of Taipei, was chosen for the project.
Construction on site started in July, 2006. The dome was assembled using the “perimeter-in” method of construction: the first nodes and tubes are settled on the supporting concrete wall. Each 3 to 5 tubes were joined to one node forming a “spider”. Each spider was then raised to the work front and tapped into place, creating rings around the base that grew one on top of the other until the whole skeleton was formed.
Coordination with other trades was easy, as the area under the dome was free of obstacles. Neither scaffolding nor other special equipment were required, and the project was completed with a perfect safety record.
Turnover of the domes and testing of the first silo started in October 2007, approximately 16 months after start of construction. The completed domes are beautiful evidence of the careful planning, execution and cooperation between the companies involved in the project, and attest to Taiwan Power’s commitment to a clean and safe environment.
