Subsea production systems benefit from RGD resistant HPHT seals in Christmas trees, manifolds, and control modules. Deepwater operations face combined high hydrostatic pressure, thermal gradients, and rapid cycling during intervention. Materials compliant with NORSOK and ISO ensure long-term reliability without frequent retrieval. Low compression set preserves sealing force over years... https://globalsealstech.com/product/rgd-rapid-gas-decompression-o-rings/
