Scope of Project
The rope terminations are used in anchoring offshore oil platforms. Although similar designs are already used extensively in industry and have a proven ability to take operating loads, Bridon’s clients required a validation analysis before accepting delivery. Bridon also held detailed hand calculations for all models; nevertheless, analysis was needed to validate these, as well as performance in the field.
"IDAC was recommended to Bridon by a supplier who could not commit to the fast-track time limits set by our customer for this project.” explains Stuart Hallam, Technical Manager of Cable Products at Bridon International “IDAC's quick and knowledgeable response to the initial enquiry gave Bridon the confidence to place an order for the finite element analysis."
The rope ends are single castings of over a metre in length, the largest of which weighs well over a tonne. The steel cable is inserted into the cavity of the casting, and then fixed in place with a setting resin to prevent it sliding out. With the socket fixed through a pinhole, it should be able to withstand cable loads of up to 5000 kN in the case of the largest socket.
Such large-scale components are obviously not suited to easy prototyping. The nature of offshore work demands safely designed parts, so accurate computer simulation offers a cost and time effective tool for the design process.
