Teledyne Supports Nekton
Seychelles Expedition

Teledyne Marine worked with the Nekton Deep Ocean Exploration as an official subsea technology partner through value-in-kind contribution of equipment, technology and support for Nekton’s Seychelles expedition in March. The expedition was a major global scientific collaboration that aims to create a step-change in knowledge of the Indian Ocean and catalyze its sustainable governance.

The Seychelles covers an exclusive economic zone of 1.4 million sq. km.

The expedition was carried out in specific areas within the plateaus of designated outer islands with depths of up to 500 m.

Teledyne Marine provided: Teledyne RESON T50-P SeaBat multibeam echosounder; Teledyne RD Instruments ADCP Workhorse; two Teledyne software packages during and after the expedition; Teledyne PDS acquisition software and Teledyne CARIS HIPS and SIPS for post-processing of the hydrographic data; Teledyne Bowtech HD cameras and LED lights mounted on the manned submersibles and ROVs; and Teledyne SeaBotix ROV LBV300-5 Mini fitted with Teledyne BlueView high-resolution forward-looking sonar systems M900-2250.

Kongsberg Application Enables
BV’s First DP Digital Survey

Kongsberg Maritime, Bureau Veritas (BV) and BOURBON have announced the successful testing of a new solution for DP (dynamic positioning) system performance and redundancy audits—a first in the maritime industry.

Developed by Kongsberg Maritime in collaboration with BOURBON and BV’s DP experts, the DP Digital Survey application runs on an industrial data management system that ensures unprecedented data consistency for the verification of installed systems. It acquires information directly from the DP system and delivers it to auditors via a secure cloud infrastructure, allowing compulsory surveys to be conducted remotely.

The DP Digital Survey application offers a distinct advantage for vessel owners utilizing the remote survey tool to collect a comprehensive quantity of test execution and completion evidence.

MBES Hydrographic System
For Island of Corsica

MacArtney France has delivered a portable multibeam echosounder (MBES) hydrographic system, designed for small vessels, to the French government organization Collectivité de Corse, in Corsica, France.

The Collectivité de Corse represents the interests of the community of Corsica, a Mediterranean island off the south coast of France. Large parts of the island are designated as the Parc Naturel Régional de Corse, not only to protect the natural landscape but the local population and cultural heritage of the region, too.

With 1,000 km of coastline, the island attracts many tourists and cruise ships, creating the need for an MBES hydrographic system small and versatile enough to be portable by road across the island to Corsica’s many harbors.

The purpose of the MBES hydrographic system is to ensure visiting vessels can securely navigate the harbors of the island, monitor the seabed to control the quality of dredging, identify obstructions on the seafloor, and verify underwater installations.

MacArtney France worked with partners Kongsberg, Valeport and SBG Systems on this project.

The scope of supply included: Kongsberg Mesotech M3 sonar; Subsea SBG NavSight inertial navigation system; Valeport miniSVS; 4G modem for receiving RTK corrections; HYPACK software for acquisition and processing; pole for deployment; and on-site installation and training.

New Gyros as Pilot Aid for Largest Construction Vessel

Silicon Sensing Systems Ltd.’s latest inertial measurement technology has been used in AD Navigation AS’s new pilot’s aid, the ADX XR, to successfully guide the Pioneering Spirit, the world’s largest construction vessel, into Maasvlakte in the Port of Rotterdam.

In the trials, precise movement data from Silicon Sensing’s CRH02 all-silicon gyros allowed the ADX XR to deliver a highly accurate and detailed 3- to 5-min. ship course prediction to the pilot.

CRH02 is a compact, low-noise, single-axis gyroscope that performs similar to a fiber-optic gyro, but is more rugged, with a lower size and weight.

Following this successful performance, AD Navigation has placed a production order for CRH02 gyros with Silicon Sensing.

Sonardyne’s SPRINT-Nav 700
For NOC’s Under-ice AUV

The U.K. National Oceanography Centre (NOC) has selected high-performance hybrid navigation technology from Sonardyne International Ltd. for the next generation of its Autosub AUV, targeted for under-ice operations.

The NOC, based in Southampton, will incorporate Sonardyne’s highest performing SPRINT-Nav inertial navigation system (INS) into the new 2,000-m depth-rated Autosub, which is being specifically developed for carrying high-performance sensors on the most demanding research missions under polar ice, hence its name Autosub2KUI (A2KUI).

SPRINT-Nav combines Sonardyne’s SPRINT INS sensor, Syrinx 600-kHz DVL and a high-accuracy intelligent pressure sensor into a single housing, making it one of the smallest combined inertial navigation instruments on the market.

The SPRINT-Nav 700, selected by the NOC, is equipped with the highest-performance available sensors, including Honeywell ring laser gyros and accelerometers, and has a conservative quoted accuracy of 0.04 percent 2dRMS.
