Inspection/maintenance
This paper compares traditional welded techniques, such as above-water repair methods and underwater hyperbaric welding, with the novel options offered by subsea connectors purposely developed for corrosion-resistant-alloy-clad pipelines.
This paper introduces a technology for offshore pipeline inspection centered on an autonomous robotic system equipped with underwater computer vision and edge-computing capabilities.
The offshore industry is actively embracing a digital-first, low-carbon future, supported by scalable demonstrators, intelligent systems, and integrated engineering approaches now entering precommercial or early-deployment stages.

Visualization technology has played a key role in reducing operational expenditure (OPEX) and improving collaboration, thus maximizing uptime across the industry throughout the asset life cycle. -
Since the recent oil price downturn, the offshore MMO market has witnessed a significant decline in global expenditure. The most severe decline in total regional expenditure is anticipated to occur in North America, with modifications expenditure forecast to drop by 56% between 2014 and 2016.

Optimization of maintenance costs is among operators’ main concerns in the search for operational efficiency, safety, and asset availability. The ability to predict critical failures emerges as a key factor, especially when reducing logistics costs is mandatory.
-
As subsea electric lines age, they are prone to cracks that allow seawater in, reducing their effectiveness, and if the leaks are bad enough, they can shut down operations.
-
Low prices will constrain maintenance and modifications in the coming year. However, maintenance can only be delayed so long, leading to a long-term outlook of growth in the market for maintenance, modifications, and operations.

This paper describes the measures put in place so that the mooring system of the Gryphon Alpha FPSO could be replaced and reconnected on an efficient schedule.
-
There are few deepwater-pipeline operators with expertise in pipeline repairs. This paper describes a strategy developed and implemented on deepwater-pipeline intervention, based on a deepwater operational experience built over a decade.
-
Compared to the US industrial average downtime ranging from 3% to 5%, the oil and gas industry’s estimated downtime ranges from 5% to 10%,indicating that improvement is needed in reliability and maintenance of facilities, equipment, and processes.

Douglas-Westwood expects 8% growth in offshore operations and maintenance (O&M) expenditure annually from 2012 to 2016. O&M are markets considerably less vulnerable to downturn than their capital‑led counterparts.
