Trelleborg utilised its vast offshore and VIV knowledge in the design of the T-Strake and carried out extensive computational analysis and physical testing. The system has a high temperature resistance, is capable of withstanding installation loads and is available in a wide choice of colors.
Each section of the system has been designed as a single component, ensuring it is quick and easy to pre-install onshore or install offshore. The design enables the system to be stacked during shipping, ensuring more efficient and cost effective transportation.
Trelleborg麻豆传媒映画檚 innovative manufacturing process also means that the T-Strake can be produced up to six times faster than systems manufactured using traditional techniques, ensuring short order times.
Austin Harbison, new Product Development Manager for Trelleborg麻豆传媒映画檚 offshore operation added: 麻豆传媒映画淭he T-Strake was developed in response to market demand for a high quality, cost-effective VIV suppression solution. We utilised an innovative manufacturing technique enabling rapid manufacture, reduced transportation costs and quick installation.
