Cygnus Instruments

Cygnus Instruments showed off their new Mk5 range of Surface Ultrasonic Thickness Gauge, as well as their latest Underwater Ultrasonic Thickness Gauge.

The Cygnus Underwater Dive Ultrasonic Thickness Gauge is used in diving applications to accurately and easily determine the thickness of materials and the Cygnus ROV Mountable Ultrasonic Thickness Gauge and Cygnus Mini ROV Mountable Ultrasonic Thickness Gauge used with ROVs to accurately measure material thickness remotely.

As well as the featured products that are used in a variety of underwater applications; Cygnus demonstrated the Cygnus Hatch Sure Ultrasonic Leak Detector and the New Cygnus Mk5 Range of Ultrasonic Thickness Gauges. The Cygnus Hatch Sure uses ultrasonic energy to improve the accuracy of leak detection for hatch covers, such as those used in bulk ships. The new Mk Range boasts new intuitive and intelligent features that improve the accuracy and reliability of thickness readings, whilst maintaining their commitment to simple and easy to use products.

These exhibits were interested in underwater, diving, surface and ROV metal thickness and corrosion monitoring; NDT services; hatch seal and leakage monitoring. And attended the Monitoring Structural Integrity: Understanding Risk and Reliability; and Oil & Gas: What’s next for Ageing Offshore Assets? conference streams.

Cygnus Instruments Ltd is the pioneer and leading UK manufacturer of ultrasonic thickness gauges used for detecting metal thickness, through coatings, to determine the levels of corrosion. Cygnus has a wealth of experience, covering over 30 years, within the industry.

DUTCH OCEAN GROUP – four organisations’ exhibits are highlighted by the Netherlands Pavilion organisers (F600).


Nautikaris obtained the agency of OxTS Ltd survey products, and showed some products at OI 2016 in the Netherlands Pavilion. OxTS designs and manufactures world leading products combining the best of Inertial Navigation and GPS/GNSS. They focus on low-cost INS using MEMS gyros and precision accelerometers. Their Kalman filter extracts the maximum information from GNSS to deliver high accuracy measurements and low drift rates. They are dedicated to designing simple-to-use products that deliver reliable and accurate results. All products are backed up with first class service and support.

TARKA-SYSTEMS presented their Marine Operations Survey System (MOSS) at the Netherlands Pavilion. The MOSS is a practical, robust, portable measurement solution for your monitoring and surveying needs. Developed and manufactured by TARKA-SYSTEMS with the needs of Marine Surveyors and Naval Architects in mind. It is not a single tool but a multipurpose solution for many different measurements.


Save time and overhead by using the MOSS system for your surveys due to the pragmatic design, clear functionality and the ability of reading a wide range of sensor inputs.

The functionality of the MOSS can be applied for marine, offshore, salvage and civil applications.

For special functionality the basic system can be extended on clients’ request.

The MOSS model is a handheld unit that provides the readout and storage of connected sensors.

The sensor values are gathered, displayed and stored internally or on a USB stick. Average values can be calculated and displayed during the measurements.

Additional to the data-gathering, visualization and storage there are possibilities to forward the data to an overall main measurement system through one of the available ports on the MOSS.

The Marine Operations Survey System (MOSS) is a multipurpose tool for field applications and survey jobs. With the MOSS it is possible to carry out different measurement with the same hardware. With multiple sensor inputs a wide range of sensors can be connected. The basic software reads, displays and stores all sensor values. Client specific software can be programmed and be installed by use of a USB stick even when the system is already in the field.

The MOSS was initially developed on request of a salvage company to be used as a portable freeboard measurement system. This to replace the traditional (old-fashioned) way of measuring the freeboard with a lead-line or going out with a RIB to read the draft marks.

After the first operational freeboard system the added value of a small, portable and battery powered system was noticed and the request for other sensor inputs (incline, temperature) followed soon.

Their exhibits were particularly interested in attending the Hydrography, Geophysics and Geotechnics; and Ocean Observing Systems: Marine Technology and Services Sector Role in the Blue Economy conference streams.


• U BOAT WORX presented theirs new manned submersible C Researcher 3. The U-Boat Worx submersibles are the most advanced private submarines ever built and have set the standards for 21st century underwater exploration. They will be showing a spectacular video.

The new C-Researcher 3 brings a whole new world with a compact three person research and leisure submersible that can explore the artefacts and seascape of the ocean for up to twelve hours of multiple dives in safety, comfort and luxury. Features such as leather seating, automatic climate control and a Bluetooth audio system complete the ‘out of this world’ experience.

Advances in design software and materials have allowed U-Boat Worx to achieve compact dimensions and a limited weight. Unlike traditional research submarines that are restricted to operate from large dedicated mother vessels, the C-Researcher 3 can be operated from a wide range of vessels including superyachts. The C-Researcher 3 can also be transported in a shipping container to minimize mobilisation time and cost.

It is the first time that a spherical acrylic pressure hull is applied to reach a depth of 1700 m.

Bert Houtman, Founder of U-Boat Worx comments: “Those lucky few diving our C-Researcher will be rewarded with stunning panoramic views of a rich and diverse underwater scenery that has been hidden from mankind since the existence of our oceans”.

Numerous unmanned submersibles were presented at the show, but the dive in a manned submersible was a completely different experience.

In the BBC documentary on the Great Barrier Reef even Sir David Attenborough was blown away by this experience. Their exhibits are of interest to, and use by scientists, researchers and the explores and adventurers of this world; and to those who attend the Ocean Observing Systems: Marine Technology and Services Sector Role in the Blue Economy conference stream.


• RADAC will present the newest version of the WaveGuide server, which is updated to the latest state of the art. The new WaveGuide server isn’t only faster, more robust and more stable. It also facilitates network connection, USB storage and RS232 output while still running at low power. The server is part of the WaveGuide, a high quality radar system which monitors waves, tide and water levels. Mounted high above the water the WaveGuide is equipped to measure waves, regardless of the most extreme conditions. It is of use to offshore wind parks, oil/gas platforms, harbours and vessels.

Their exhibits are of particular interest to those attending the following conference streams: Hydrography, Geophysics and Geotechnics; Marine Renewables; Monitoring Structural Integrity: Understanding Risk and Reliability; and Ocean Observing Systems: Marine Technology and Services Sector Role in the Blue Economy
