Compact, high-performance sensor development – a balancing act you need to get right
Subsea vehicles are becoming more capable, whether it is a resident robot that can spend months beneath the surface, or a large ROV performing functions like station keeping without human input. Critical to these functions are the sensors used to input data from the surrounding environment. One such sensor is the Doppler Velocity Log (DVL), which is used to provide vehicles a control system with speed over ground measurements.
Helping the rapidly expanding USV sector strengthen data collection capabilities with ADCPs
Oceanographic measurements from Uncrewed Surface Vehicles (USVs) are opening new possibilities, and these innovative measurement platforms are pushing in-situ data collection capabilities beyond the norm. Which aspects must users keep in mind as the industry starts to deploy these new vehicles?
Fulfilling the changing needs of the subsea vehicle market
Doppler Velocity Logs (DVLs) are an essential navigational aid used in subsea operations where GPS is unavailable. DVLs use the Doppler effect to provide estimates of velocity relative to the seabed, preventing errors from accumulating within a vehicle’s navigation system. These sensors ensure that remotely controlled and autonomous underwater vehicles (ROVs and AUVs) can perform a variety of tasks accurately and consistently with minimal human input.
The Other 70%: Connecting the ocean to our daily lives with the Nortek podcast
The ocean affects many aspects of day-to-day life for nearly everyone on Earth, yet these connections are often overlooked. In The Other 70% podcast, we highlight companies, individuals and organizations whose work relies on our blue planet and strengthens these connections, in an accessible way that anyone can learn from and enjoy.
Increased demand for ROVs and deepwater equipment indicates a more optimistic offshore market
The beginning of 2021 saw a very positive outlook for offshore operations and maintenance (O&M), with a record number of orders for Seatronics’ VALOR ROV and increased demand for deepwater equipment. In an offshore market on the rebound, Nortek’s tried and tested subsea navigation sensors have helped Seatronics provide reliable solutions to their clients.
Women in Nortek share insights on working in the ocean tech industry
Are you considering working in the ocean technology industry, but don’t know what your options are? Talented and inspirational women from Nortek share their paths into what they describe as incredibly fulfilling careers in the ocean technology industry.
Nortek provides practical, technical training in ocean technology for academics across the world
For academics doing research with ocean technology instrumentation, not all skills can be developed in the lab. Geological Survey of Japan's Dr Mamoru Tanaka joined Nortek Japan for two months to receive practical training in ocean technology and upskill in the principles and applications of ADCPs and ADVs. He is one of many academics that have been given practical training by Nortek to successfully deploy acoustic instrumentation for ocean research.
DVLs with bottom-tracking algorithms that improve accuracy and reliability for subsea navigation
Navigating subsea presents many challenges, and having a reliable navigation system is critical for successfully conducting a subsea mission with an ROV or AUV. Why is a sophisticated DVL with an advanced bottom-tracking algorithm crucial for subsea vehicles navigating in challenging environments?
NORBIT Aptomar acquires the SeaDarQ radar system for environmental monitoring
Nortek announces the sale of its SeaDarQ radar technology for environmental monitoring and oil spill detection to NORBIT Aptomar, a technology provider to global maritime markets.
Why patches are the best anti-biofouling solution for an ADCP
We all want our ADCP to gather data accurately and work for as long as possible, but biofouling can stop us achieving both of these objectives. When marine organisms accumulate on a transducer surface, the instrument’s performance can be greatly diminished.
New 250 kHz version of Signature VM Coastal offers accurate current profiling to 200 meters
Nortek has launched the Signature VM Coastal in a 250 kHz version. This completes the company’s suite of vessel-mounted acoustic Doppler current profilers (ADCPs) designed to measure coastal movements throughout the epipelagic zone.
Nortek redefines current profiling from autonomous vehicles
Installation and operation of current profiling instruments on remote unmanned or autonomous surface vehicles (USVs and ASVs) can be fraught with difficulties. Nortek has made it a lot simpler – and more useful – by combining its Signature VM acoustic Doppler current profiler (ADCP) system with specially customized software.
