SUBSEA RELIABILITY IMPROVED: Technological Progress of Subsea Thrusters Saves Both Money and the Environment.

11/2018

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.

Know What’s Below: General Dynamics Mission Systems Bluefin Robotics® Unveils the Bluefin™ - 9 UUV

11/2018

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.

Aiding AUV Operational Decisions with CARIS Onboard

07/2018

In April 2017, CARIS Onboard™ Product Manager, Travis Hamilton, was onsite with the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) to conduct a CARIS Onboard installation and trial. JAMSTEC is an organization committed to supporting ocean research and development activities which covers a broad spectrum of marine science and technology. With several institutions located across the country, their mandate is to contribute to the creation of a holistic understanding of global concepts surrounding the ocean.

Ping and Done: Evolving QPS Technology for the new Era of Autonomous Hydrography

07/2018

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.

The Development of WaveRadar for Ocean Wave Measurement

11/2017

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.

SUB-BOTTOM PROFILING ACQUISITION & PROCESSING IN HYPACK®

07/2017

The newly launched HYPACK® SUB-BOTTOM is a sub-bottom profiling acquisition and processing software package designed for marine geophysical, engineering & geotechnical site surveys, dredging, mining applications. It’s a simple and easy-to-use solution for most sub-bottom profiling survey requirements. Basic sub-bottom profiling acquisition & processing has been available in HYPACK for the past few years, but during the first quarter of 2017 a considerable amount of effort has been put into improving the stability, memory allocation and features of the program. This article is highlights some of new features and functionality of HYPACK® SUB-BOTTOM.

The SWiFT SVP is Valeport’s latest addition to its portfolio of sound velocity sensors and profilers

Listening to your customer is key when designing a new product

07/2017

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.

Improved Operational Decision- Making for USV Fleet Surveys

07/2017

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.

WHOI scientists partner with Rhode Island fishermen to understand rapid changes in Gulf Stream-dominated east coast shelf waters

02/2017

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.”
