MACSEA supplies multibeam sonar for C-Innovation ROV

Tritech’s range of Gemini multibeam imaging sonars are rapidly becoming the sonar operators adopt to navigate, visualise and monitor in poor visibility and turbid warters.

C-Innovation do Brasil recently used the deep-rated Gemini 720i to inspect the hull of an FPSO turret; to inspect a repair and to monitor the surrounding environment.
The inspection was to locate a repair, approximately 40cm wide, on the hull of the FPSO. During the operation, the vehicle was slightly elevated and tilted towards the riser and held at a depth of 15 m away from the hull of the FPSO, due to the vast number of risers and mooring lines; therefore the Gemini sonar was operating at long-range.
C-Innovation operated a Schilling ROV, as fitted with the Gemini 720id and Tritech’s local service partner, MACSEA Ltda provided local customer technical support for the demonstration.

Renan Ocampo, Support Technician, MACSEA commented:
“We developed the Gemini brackets based on Schilling ROV frame, making it adjustable and easy to install, providing a good inspection angle.”

Alex Maia, General Manager, C-Innovation do Brasil commented:
“Our ROV fleet is adaptable to host many plug-and-play technologies, including Tritech’s Gemini. We have made several riser inspections where the Gemini helped quite a lot, especially around the TDP [touch-down point] where there was low visibility, here we could clearly see the trench below the suspension, thanks to the imagery of the Tritech Gemini sonar.”

Tomás Peixoto, ROV Operations Coordinator, C-Innovation do Brasil commented:
“We were amazed by the image quality and the operational performance of the Gemini sonar which enhanced our ability to navigate in low visibility, as well as provide a clear window for target identification during the survey. Overall we completed the job in a safe and timely manner.”

Tritech Sonar for AUV Project

MACSEA secures order to supply imaging sonar technology for AUV optimal navigation.

MACSEA secures order to supply imaging sonar technology for AUV optimal navigation. Such sonar technology allows coverage of larger areas (up to 120m) independent of the conditions of visibility, illumination and water turbidity . The real-time multi-beam acoustic imaging sonar (Tritech Gemini) will be used for the mapping and location of the AUV scenario, while the compact CHIRP imaging sensor (Tritech Micron Obstacle Avoidance Sonar), are fundamental for the detection of obstacles in 360º swath.

MACSEA Completes Sistac ROV Upgrade Project

The MACSEA team of the ROV SAAB Seaeye Tiger upgrade project has successfully delivers the system to the customer.

The main objective of the project was to change the characteristics of the vehicle in order to improve its performance, through the interface of a new motion sensor (TOGS), exchange of its data multiplexing system (Focal 907) to interface a new video device (HD IP Camera), increase its operating capacity in low light environments with the addition of two more LED lights to the vehicle. In addition to these upgrades described above, the telemetry of the vehicle and its navigation sensor (Sonar Super SeaKing DST) will operate via fiber optic link.

Tritech Sonar for Sistac ROV

MACSEA has sold a multibeam sonar Gemini, to remotely operated vehicle (ROV) providers Sistac Sistemas de Acesso.

Sistac initially hired a deep-rate Gemini to evaluate its performance during sea trials. The Gemini 720id multibeam sonar is now the primary sonar onboard Sistac’s Soil Machine Dynamics (SMD) Atom Work-Class Remotely Operated Vehicle (WROV).

The ATOM ROV is stationed on board the Sistac Vitória vessel, which is hired by Petrobras for ROV and dive support operations.

The sale of Gemini follows the opening of Tritech’s dedicated support hub with its partner MACSEA.

Mario Gonçalves, Sistac, said: “Sistac is extremely pleased to have purchased the deep-rated Tritech Gemini to assist our operations in Brazil. We worked with MACSEA, a partner of Tritech, for a recent technical demonstration of the Gemini 720id multibeam sonar which validated the quality of the product and its suitability for our vehicle.”

Antonio Silva, Commercial Manager for MACSEA, added: “MACSEA’s aim is to serve the Brazilian market with locally-based equipment, we are therefore delighted by the sale of a Tritech Gemini 720id to Brazilian company Sistac for their WROV.”
