1. Service Description
Oceaneering offers a comprehensive suite of subsea pipeline repair solutions designed to restore integrity and extend the life of damaged or leaking pipelines without requiring costly shutdowns or hyperbaric welding. Their mechanical repair fittings enable permanent, high‑quality seals and structural reinforcement for the design life of the pipeline (typically 25+ years). The portfolio includes both diver‑installed and diverless (ROV‑operated) systems, covering nominal pipe sizes from 2 to 48 inches and pressure ratings up to ANSI Class 2500 (10,000 psi). Oceaneering’s repair technologies eliminate hotwork permits, reduce offshore intervention time, and accommodate sweet and sour service environments. Pre‑repair pipeline preparation is supported by abrasive waterjet cutting, diamond wire sawing, and high‑pressure coating removal tools. Post‑repair integrity verification is performed using advanced non‑destructive testing (NDT) such as ultrasonic mapping, digital radiography, and automated UT scanning. The company also provides pipeline end preparation, mechanical pipe lift frames, and subsea pig launchers/receivers to support complete repair campaigns. All equipment is ROV‑ or diver‑deployable and designed for water depths up to 10,000 ft (3,048 m). With thousands of global installations, Oceaneering’s repair solutions are field‑proven, API/ASME compliant, and certified by DNV GL and Bureau Veritas.
