Abstrakt:

This paper presents the application of recycled tubular, flowline, and umbilical in coastal protection structures. Flowline and tubular are found to improve the load resistance capacity of concrete beams. Embedment of flowline, umbilical, and tubular into concrete beams would be beneficial to the structural performance, which do not noticeably alter the initial cracking strength of the concrete beam but will provide good post-cracking resistance. A techno-economic analysis was performed, which revealed that coastal protection concrete structures with decommissioned components accounting for more than 25% of the concrete weight could be both economically viable and environmentally friendly options. Since global warming is the most dominant environmental impact (i.e., 63%), recycling these decommissioned components from offshore structures could impose positive environmental impacts. Given the limited supply of construction materials in the remote coastal area as well as its proximity to decommissioned oil and gas rig sites, these decommissioned components could have great potential for use as construction materials in the coastal areas adjacent to the oil exploration. This preliminary study finds no showstopper for the concept of recycling the mentioned decommissioned components as coastal protection concrete structures from structural performance, environmental impact, and economic perspectives.
