Mini-sparker purchased 

The University of Perpignan, France, has taken delivery of a next-generation SIG, France, Pulse S1 mini-sparker. SIG said the Pulse S1 is a light energy source with easy adjustment of power. "It is a safe, powerful tool for shallow, high-resolution seismic surveys," the company said.

Iver2 AUV delivered to Estonia 

OceanServer of the USA reports it has delivered an Iver2-580 EP42 (expandable payload) AUV to Tallinn University of Technology (TUT) in Estonia.

"TUT has a long track record of utilising new technology for research into real world applications. The researchers at the University expect to use the Iver2 platform to develop and demonstrate software solutions supporting AUV autonomy in the context of the Baltic Sea," said OceanServer. 

The Baltic Sea presents many operational challenges such as brackish waters, very low visibility, heavy marine traffic and many obstacles in the water. 

"The Department of Computer Science of Tallinn University of Technology plans to couple mission-time analysis of data with the ability to augment the mission in real-time," said OceanServer. "The Iver EP platform provides users with a fully developed remote helm capability that allows predefined missions to be interrupted and changed. This flexibility will be relied on as a valuable tool for developing and testing innovative in-situ marine scientific data collection techniques specific to the Baltic Sea area." 

The company added that the University hopes to establish AUV test methods for a range of parameters and non-traditional parameters like underwater noise. The EP42's open system architecture gives TUT the opportunity and flexibility to add additional sensors to help support these efforts, it said. 

Gavias for Poland 

Teledyne Gavia, Iceland, reports it has completed a contract with the Armament Department of the Polish Ministry of Defence for the delivery of two Gavia Defence AUV systems for mine countermeasures (MCM). 

The provision includes all required topside equipment and AUV operation and maintenance training.Teledyne Gavia completed a competitive tender process for delivery of the first MCM AUVs into Poland, winning the contract on the basis of best value with conformance to the required functional and technical parameters, said a spokesman. 

The Gavia vehicles delivered are equipped with EdgeTech, USA, 2205 sidescan sonars. The simultaneous dual frequency 600/1600kHz 2205 sidescan sonar and the Kearfott, USA, T24 inertial navigation system allow the Gavia to gather high-resolution, accurately navigated, sonar images while remaining submerged for several hours of continuous operation at survey speeds up to five knots, the spokesman said. 

"The addition of a high accuracy GPS and the augmentation of the INS by long baseline beacons ensures precise navigation during even longer duration and deeper missions. This combination of sensors makes it ideal for mine countermeasures and search and salvage operations, in continental-shelf waters and beyond," he said. 

The sea acceptance trials (SATs) took place at the Teledyne Gavia proving grounds near Kopavogur, off the west coast of Iceland.The tests were supervised by representatives of the Polish Navy, and the results were checked by specialists from 4 District Military Division (Gdansk)."Data analysis during the SATs and training confirmed the vehicle performance and suitability for MCM search, location and identification missions," the spokesman said. 

The vehicles were supplied through Enamor, Poland, Teledyne Gavia's official representative in Poland. 

Survey vessel 

A new 14-metre catamaran has been delivered to coastal survey specialist Osiris Projects, UK, by GRP workboat builder Blyth Workcats, UK. 

The new boat, named Proteus of Liverpool, has been custom-built at the Blyth Workcats yard on Canvey Island to provide a fast yet stable and comfortable working platform for coastal survey work, according to a spokesman. The boat has been fitted with a range of high specification sonar and acoustic positioning systems that will provide the company's clients with high quality survey data enhanced by the stability of the new boat, he said. 

The Proteus is the fifth vessel in the Osiris Projects fleet and has MCA (UK Maritime and Coastguard Agency) Category 2 approval to work up to 60 miles (97 kilometres) offshore. 

"With a maximum design speed of 24 knots the new boat will be able to get quickly on station and commence surveying with minimum delay," the spokesman said. 

The new survey boat will work primarily for oil and gas and offshore renewable clients, performing cable and pipeline pre- and post-installation route surveys around the coastline of the UK and Northern Europe. It includes a moon pool to house a retractable sonar deployment system, a hydraulic A-frame and retractable transducer mounts and is capable of operating a full spread of survey sensors. 

"The boat's draft of just 1.1 metres also makes it ideal for working in the extreme shallows encountered during precision littoral survey contracts," said the spokesman.


iXBlue, France, has announced it is to supply QUADRANS fibre optic gyrocompass systems for installation aboard the four new Tide-class tankers of the UK Royal Fleet Auxiliary (RFA). 

The systems, to be supplied to UK-based Kelvin Hughes, will be integrated as a sub-system of the integrated bridge systems for delivery to Daewoo Shipbuilding and Marine Engineering in South Korea where the vessels are under construction. 

The deliveries will be made up of twin QUADRANS gyrocompass units, control and display and data distribution units and a comprehensive network of ancillary repeaters from UK-based Marine Data. The QUADRANS will deliver heading, rate-of-turn data for navigation sensors along with vessel motion data to support helicopter operations that represent one activity of the multi-function vessels. 

iXBlue said it had worked closely with Kelvin Hughes and Marine Data to design a type approved system meeting the precise requirements of the end user. 

Wave buoys

AXYS Technologies, Canada, reports it has delivered three more TRIAXYS Next Wave directional wave buoys to the Instituto Oceanográfico De La Armada (INOCAR) of Ecuador. The company said the buoys will be added to the existing coastal wave monitoring network of TRIAXYS buoys owned by INOCAR and deployed along the Ecuador coastline.

The AXYS services team travelled to Guayaquil to provide instruction to INOCAR personnel on managing and operating the network and will visit again for continued system training. 

"INOCAR chose to use the TRIAXYS wave buoy based on its success in other coastal monitoring networks for similar clients in South America," said AXYS. "INOCAR has implemented a large network of AXYS systems along the coastline of Ecuador." 

Hyperbaric sale 

SOS Hyperlite, UK, has announced the delivery of ten Hyperlite Mod 1 portable hyperbaric chambers to Basarnas, the Indonesian search and rescue (SAR) agency. 

Basarnas is tasked with implementation, training, coordinating and controlling SAR activities for missing persons and lost vessels including ships and aircraft, as well as providing SAR assistance for disaster relief in accordance with national and international regulations.

It is anticipated that the ten systems will be strategically located at Basarnas bases around the Indonesian archipelago, primarily to treat divers suffering from decompression sickness. Indonesia has more than 17,500 islands spread over 1.9 million square kilometres and is widely believed to have the greatest diversity of marine life in the world.

"Used primarily for the treatment of pressure related injuries amongst military, commercial, scientific and sports diving accidents, as well as in battlefield medicine and aeromedical evacuation, the SOS Hyperlite's unique portable design makes it ideal for quick deployment and asfirst response medical aid," said a spokesman. 

Indonesian Tiger 

Seascape Surveys of Singapore has acquired its third Saab Seaeye, UK, Tiger ROV for operations in Indonesia.

"The Tiger offers a good combination of size and power for jacket inspections," said Seascape MD Peter Reichlmeier.

He explained that Tigers are used for digital inspection work of subsea jackets, platforms and other structures. "We have been using Tigers for this work for the last four years and find them reliable and versatile," he said.
