Change of Management for Nortek

After over two decades at the helm of Nortek, a specialist in oceanographic instrumentation, Atle Lohrmann is taking on new challenges at newly started Hefring Engineering in Boston. Nortek’s new CEO, Finn Ivar Marum, has been entrusted with the task of ensuring Nortek’s continued growth.Nortek was established in 1996, when Atle Lohrmann set up offices outside Oslo, Norway, and started building up production capacity for Doppler instrumentation.Since then, Nortek has grown rapidly, with its revenues increasing from $985,000 in 1996 to $24.6 million in 2018. Many factors lie behind the

new system was being presented to the OceanObs’19 community for feedback to ensure it would be “fit for purpose.” Throughout the event this concept was often raised for all technologies as a way of reminding the participants that there are many solutions to diverse ocean observing needs.Nortek was also onsite at OceanObs’19 embracing the conference charge to “improve the efficiency, decrease the cost, or add new observations that were not previously possible.” Their solution was the ECO platform.

companies. Attendees were given an opportunity to pilot the vehicle in and out of the water using the handheld controller. Three beach profiles were run using GPS autonomy, and later a state profile line was run. The Sea Ox, which can pressure sensor based bathymetric data, was also equipped with a Nortek ADCP and AML turbidity and sound speed sensors.The vehicle can be used in autonomous mode using inertial systems or GPS, and can be driven using RF antenna, RF buoy or using a tether. Trialed this summer at ANTX, the inertial system achieved a misclosure of 3.38m after a 2,813m mission with 44 turns

A New USV for Ocean Surveying

A new unmanned surface vehicle (USV) designed for the Chinese market offers an open and low-cost platform to measure water current and direction. Nortek China has integrated Doppler instrumentation on the vehicle to help better meet user requirements for ocean surveying.The new USV has an IPC (Industrial Personal Computer) as the main operation platform and uses Remote Desktop, a remote control technique, to communicate with all the instruments installed. This means that the vehicle offers an open and low-cost platform for customers who need to carry out several different tasks at the same time.

Nortek Opens Australian Office

Nortek, a leader in Doppler-based measurements in marine environments, has opened the latest of its global network of offices in Melbourne, Australia. This facilitates access to cutting-edge Doppler instrumentation for researchers and engineers in Australia and New Zealand.This is the company’s first office in the region, creating a strong local point of contact for sales and support. The Port Melbourne office also gives Nortek a platform from which to extend its reach throughout Australia and New Zealand, an area that has been important for the company since it was founded over two decades ago.

The robust buoy is equipped with a seabed mounted Nortek AWAC to provide three-dimensional current profiles in cells with thicknesses from 0.25 to 4m. The ADCP is additionally furnished with a Prolog board for internal wave processing, and it can also be used to estimate suspended sediment loads by correlating the acoustic back scatter intensity to a site

Current Profiling & China’s Maritime Infrastructure Drive

China’s recent wave of infrastructure renewal has included a large portfolio of developments, such as ports and other developments, that have a subsea component. Accurate, efficient and cost-effective current profiling is vital in the successful implementation of major maritime projects.Nortek has been able to play a role in this side of China’s economic revolution, through its collaboration with a subsidiary of China Communications Construction Company (CCCC), a Fortune 500 listed firm that has been at the forefront of the infrastructure drive.CCCC & NortekCCCC’s hydrological

The equipment offers the prospect of at least five years’ running time without needing maintenance, and probably a lot longer. So it could serve well

Collaborators Make ROVs Smaller and More User-friendly

. Getting it all to work together takes a high level of collaboration between professionals, located around the world.The Defender models now being produced by Pennsylvania-based VideoRay, a world leader in inspection-class ROVs, are a prime example.For these vehicles, Norwegian Doppler specialist Nortek deployed its DVL1000 Doppler Velocity Log in collaboration with both VideoRay and Vermont’s Greensea Systems – which supplied the OPENSEA operational software platform, inertial navigation, and an autonomous control system for the ROV – to create a versatile, powerful and extremely
