Hydrographic-based projects focusing on Offshore Wind Farms (OWF) pose unique challenges at every stage of the survey workflow. Acquisition requires integration of multiple sensor types, and project requirements often specify concurrent data collection posing installation, timing, and positioning challenges. Post-processing requires users to process, review, and if necessary, correct enormous multi-variant data sets. Surveyors continue to push for increased automation in these and other related processes. Furthermore, data fusion across these temporally and spatially variant data sets is critical for proper analysis in order to aid decision-making. Throughout the process, stakeholders need to communicate to each other, even if they have different backgrounds and/or project objectives. The question then is how can the surveyor best communicate with stakeholders, facilitate decisions, and then feed adjustments back into the survey workflow? The answers are found within the innovations of the QPS workflow brought about through the merger of complementary technologies both internal and external to the company itself. This working environment was created to be seamless throughout every stage of the project lifecycle. It is powerful enough to handle complex integrations and data acquisition, automated to reduce mistakes and yet simple at critical steps to provide familiarity and clear understanding for stakeholders. This paper introduces the common survey requirements throughout the various stages of an OWF lifecycle, and derives critical success factors necessary to meet them from real client case studies. Through automation, quality integration/acquisition, reductions in human error, and intuitive comprehension, the QPS workflow is uniquely designed to achieve these success factors. Regardless of a person’s background, QPS solutions are aligned to work together to enhance the capacity of all team members involved in a wind farm project by facilitating fluent workflows through all project stages.
Developing technologies that set new standards within the marine industry takes time. Once in use, however, a robust new technology often proves superior under several parameters. This is the case of the Danish innovative company Copenhagen Subsea A/S. Founded in 2014, Copenhagen Subsea A/S develops and manufactures four sizes of electrical rim-diven thrusters for the most commonly used subsea vehicles in the marine industry: ROVs, manned submersibles and AUVs. Customers include companies and institutions within both the industrial segment and universities.
General Dynamics Mission Systems has a history of success in the development and delivery of mission-critical solutions for the undersea domain. With Bluefin Robotics’ legacy of design and developmental know-how and General Dynamics’ extensive engineering reach and customer intimacy, a new generation of autonomous unmanned underwater vehicles (UUVs) was created to meet dynamic operational needs in challenging underwater environments. Most notably, General Dynamics is the systems integrator for the U.S. Navy’s Knifefish Surface Mine Counter Measure program of record. A highly advanced derivative of our commercial Bluefin-21 medium-class UUV, Knifefish autonomously searches, detects, classifies, and identifies buried, bottom, and volume mines in high-clutter environments in a single pass.

The implementation of autonomous technology in hydrography has seen steady evolution for 20+ years. The initial developments focused on deploying large diameter (0.5 to 1m) vehicles (AUV’s) at great depths. AUV’s have quickly proven to be cost-effective solutions for obtaining high resolution bathymetry, imagery and photographic images in environments where preceding technology fell short. The most recent innovation surge is focusing on autonomous surface vessels (ASV’s) where organizations have found great gains to be made by removing personnel from the vessel altogether. Since 1997, QPS has provided options for the user to minimize the interactions with the surveyor and the system by automating key functionality. The combination of QINSy’s automation and Qimera’s data processing innovations (Wilson et al., 2018) provides a tightly integrated solution for organizations to embark on this new era of Hydrography.

Offshore oil and gas platforms are typically located in harsh environments. Think of the North Sea between the UK and Norway, the South China Sea and the Gulf of Mexico. Severe winter storms, typhoons, and hurricanes are commonplace. The offshore industry is well practiced at dealing with such extremes of nature but relies upon the provision of precise meteorological and oceanographic data to do so. Understanding the magnitude and complexities of ocean waves around offshore structures is crucial for the safe berthing of support vessels, landing of helicopters, for safe working of men and machines on deck, and for confirmation that operational platform response parameters are within design limits. Furthermore, these data are essential for the validation of numerical models used in the structural design of offshore platforms, informing the design and management of offshore structures now and into the future.

As a manufacturer, we are always striving to create products that we believe to be what the end users desire. The technology around which our lives revolve these days has had a strong influence over what we expect from products in every area of life. For instance, I have my smartphone, tablet and laptop; I have high speed access to information and data via the internet. Hardware is easily charged, memory is plentiful and expandable, quality is good and costs are reasonable. So, these are the standards I expect from the equipment I am about to use when hydrographic surveying. Valeport has led the way in sound velocity technology for more than a decade and our latest addition to the portfolio, the SWiFT SVP, was designed from the outset with customer feedback front of mind and a practical understanding of what customers actually want from an instrument.
Significant interest in autonomous and unmanned vehicles has developed within the survey community during the last few years. Unmanned Surface Vehicles (USV’s) are being considered for tasks such as data gathering in waters considered too shallow for manned vehicles and in areas presenting hazardous operating conditions. Looking forward, the concept of operating a fleet of autonomous and unmanned surface vehicles, with or without manned vessels as part of the fleet, holds great promise to improve survey efficiency.
Today’s shallow water multibeam echosounder are capable of efficiently delivering bathymetry, backscatter and water column data types. To benefit from this technology, Hydrographers are having to adjust their data collection and data processing workflows to deliver detailed and accurate information in an effective manner to a wider variety of End Users.

In 2011, oceanographer Glen Gawarkiewicz sat in the back row at a National Science Foundation (NSF) public hearing about the upcoming installation of a vast and long-term ocean monitoring system, called the Ocean Observatories Initiative Pioneer Array (Pioneer Array). The chosen location, right off the coastal waters of New England, meant the array could interfere with fishing and shipping, and there was concern that the science generated by the array could be used to force fisheries closures. The people whose livelihoods depend on this ocean region were at the hearing and they meant to be heard. “There was a very crowded room in the public library in New Bedford,” recalls Gawarkiewicz, “and there were some contentious moments.” He was sitting next to a woman he hadn’t yet met, and Gawarkiewicz remembers one of them said to the other, “There’s got to be a better way than this.”
