... be a viable alternative to improve well offtake rates. Chemical sand consolidation can give a formation some additional residual strength in order to enhance the maximum sandfree rate (MSFR). Sand production in weakly consolidated reservoirs will occur when stresses in the well/perforation tunnel walls...

...., fax 01-972-952-9435. Abstract Full-scale polyester ropes were tested to determine the impact of damage on the strength of polyester rope used as mooring lines for deepwater structures. The ultimate goal of this project - to provide information on the residual strength of damaged polyester rope...

.... It should also be noted that the metocean condition/direction that results in the highest component utilizations or highest base shears may not always produce the lowest platform RSR. Residual Strength The ultimate strength of an offshore structure in a damaged condition is expressed as the structure s...

In addition to generating fatigue data covering endurances to around 20 million cycles, two ropes (10 tonne and 250 tonne) were each tested to 40 million cycles without failure. Post test examination and textile yarn residual strength tests revealed that no scale effect...

This aimed to assess the residual properties and remaining service life of the HMPE ropes and compare the data to new tether data and prediction tools used in the design of new mooring tethers. The evaluation included residual strength, residual tension-torque fatigue...

ABSTRACT A test program consisting of 13 steel tubular brace specimens with dent damage and various diameter-to-thickness (D/t) ratio was conducted to assess the residual strength and repair of damaged tubular braces in offshore platforms. Specimens were inflicted with a dent having...
