France-based STAPEM Group has chosen Sonardyne’s Ranger 2 Ultra-Short BaseLine (USBL) technology as the permanent solution for one of its flagship offshore support vessels, the STAPEM Boreale.Operating in one of STAPEM Group’s key regions, Angola, the vessel is now equipped with a Ranger 2 GyroUSBL 7000 system, an all-in-one, high-performance USBL system for precise positioning performance, previously used on a hire basis.Ranger 2 GyroUSBL 7000 is optimized for ultra-deepwater operations and, like all Ranger 2 GyroUSBL systems, includes a single, pre-calibrated transceiver head.

Offshore service provider OS Energy has adopted Sonardyne’s SPRINT-Nav DP dynamic positioning (DP) reference system to support its marine renewable energy projects in the North and Baltic Seas. SPRINT-Nav DP will enable OS Energy to maintain DP integrity, even in shallow water and GNSS-compromised environments that are increasingly characteristic of offshore wind construction and maintenance activities. Housed within a single, pre-calibrated unit, the easy to integrate system allows operators ride out GNSS disruption, maintaining safety, accuracy and DP certification.

Back in 2017, Ocean Infinity made a novel move; deploying six autonomous underwater vehicles (AUVs), instead of just one, from a single vessel, vastly increasing the ground that could be covered in a single survey. Now the firm is taking the use of remote, robotic systems a significant step further.Back in 2017, Ocean Infinity made a novel move; deploying six autonomous underwater vehicles (AUVs), instead of just one, from a single vessel, vastly increasing the ground that could be covered in a single survey.

ROV manufacturer Forum Energy Technologies has completed the construction of what it says is a highly advanced submarine rescue vehicle (SRV), which may be utilized to extract submariners from distress situations.According to Forum, the LR-class SRV is capable of rescuing up to 17 people at a time and operate at depths of up to 600 meters. "The new model has increased power and an advanced auxiliary thruster control system that allows for speeds of up to four knots, enabling it to operate in high currents.

Driven by the need to organically protect maritime Task Groups from the threat of sea mines, the Royal Australian Navy is introducing a deployable Mine Counter-Measures (MCM) capability under the first phase of Project SEA 1778.The Royal Australian Navy’s (RAN) SEA 1778 deployable Mine Counter-Measures (MCM) capability is both a small step forward in the spiral development process and a “technological leap” into autonomy.”The RAN is looking to replace its four legacy Huon-class minehunter coastal ships (MHCs) with a new deployable MCM capability.

Designed to combat below-the-surface terrorism, Sea Wasp is the latest generation remotely operated vehicle (ROV) from defense and security company Saab. Presented at the Navy League’s Sea-Air-Space Exposition in National Harbor, Md., Sea Wasp has been engineered to relocate, identify and neutralize underwater improvised explosive devices (IEDs). While most underwater IED threats are disposed of manually by trained explosive ordnance disposal (EOD) divers, Sea Wasp is operated remotely by two-person teams from the surface, allowing operators to keep a safe distance from the explosives.

“The collaboration between Nortek and the entire PUMA team has resulted in an tool that provides unique information to the sailing crew. They can now measure leeway, a first in sailing, and use it to measure ocean currents much more precisely than ever before,” said Atle Lohrmann, CTO of Nortek. “This is the biggest advancement in sailing instrumentation since the invention of the GPS,” said Hopkins, who runs performance testing for PUMA and worked with Nortek on the project. “Nortek adapted their new DVL technology to our sailing performance needs, to measure very high speeds along the boat's track and very low speeds across it. Leeway is the sideways skidding angle a boat makes as it sails forward.

SeeByte, the global leader in creating smart software technology for unmanned systems, and VideoRay the world leader in Inspection Class-ROV technology, have announced their decision to enter a partnership with the aim of developing solutions to improve value to their customers. The decision follows the success of SeeByte’s SeeTrack CoPilot integration with the VideoRay micro ROV which was demonstrated at VideoRay’s VIPS 2011 conference last month in Florida. The demonstration…
