Clean Sea is an advanced robotic technology aimed at providing a cutting-edge and highly cost-effective solution to the increasing demand for both environmental and asset integrity monitoring in new and more challenging oil and gas developments, notably deep water and arctic areas.
Clean Sea is built around a unique concept of hybrid, modular and low-logistics ROV/AUV, easily reconfigurable for several applications, including (but not limited to): environmental monitoring tasksautomatic water samplingdetection and accurate localization of hydrocarbon leakages (from flowlines, SPS templates, etc.)seabed acoustic surveysvisual inspection of pipelines, SPS, jacketscathodic protection surveyspipe tracking (buried and exposed)
This (patented) technology originates from a successful R&D project sponsored by eni and eni Norge and carried out by tecnomare between 2011 and 2013. Clean Sea technology was successfully proven over comprehensive trials carried out during 2014 and 2015 in environmentally different sites such as Lake Vattern (Sweden), offshore Hammerfest (Norway), Caspian Sea (Kazakhstan), Sicily Channel and Adriatic Sea (Italy). The successful trials have proven the viability of Clean Sea concept as well as the benefits that this technology will provide to the oil and gas industry in terms of operational flexibility, cost savings, asset integrity preservation, performances, safely operations in critical environments.
Following the successful conclusion of the trials program, Clean Sea is currently transitioning to fully operational deployment, allowing the substitution of traditional ROV-based techniques and costly dedicated vessels. Moreover, the modularity of the system is fully exploited by continuous addition of new functionalities, in pursuit of the strategic evolution of the initial basic concept.
The paper provides an overview of Clean Sea technology and advancements, and explains the basic concept of its operational capabilities. Examples of the most significant results achieved will be provided, including details on the on-going development program. Case studies for Clean Sea operation will also be presented and commented.
