coatings in harsh environments. Their solution saves users more than 30% on material and labor, while increasing or maintaining asset lifetime, reducing toxin exposure/imprint, and providing a high-volume value add for a fishery waste stream.Marecomms Inc. (Halifax, NS) designs and builds robust and broadband wireless communication solutions for maritime environments. Their first underwater wireless communication product, RObust Acoustic Modem (ROAM), has been put to numerous tests in challenging ocean environments in the North Atlantic and shown to offer nearly 200 times faster connection speeds than

AUV Case Study: Marine Roboticists are Turning AUV Sight into Perception

. It’s risky.”To address this problem, AutoTRap delivers real-time performance on the embedded hardware of the Gavia. As soon as it finds an object, AutoTRap sends a message to other onboard AUV software so it can (for example) reroute for a closer pass. On an AUV equipped with an acoustic broadband transmitter, AutoTRap can help pass object detections in real-time to a mission planner on the surface.  Because of the wide range of objects of interest (mines, pipelines, shipping containers) Balasuriya and his team needed AutoTRap’s object recognition capability to be versatile.

machine learning algorithms. It also means making the interface for the human operator as simple as possible, first through a mission planning app and second through a Dashboard for presenting the results of the mission.4G/LTE is also much more standard these days. It’s a more recent mobile broadband internet access offering higher capabilities in connectivity as it offers a higher rate of data transfer. During the ARGOS Challenge we experienced black spots with the Wi-Fi network even on small sites because of interference caused by metallic equipment. Our latest robot design has a dual router

Flooded Member Detection Using ROVs

the first of its kind to utilize digital acoustic detection instead of typical harmful gamma rays to inspect offshore platform members or subsea pipelines for flooding as a result of cracking, damage, corrosion, and/or other defects. The ISFMD is suitable for small ROV deployments as it uses a compact broadband ultrasonic probe paired with an advanced digital signal processing engine to provide reliable readings. The ISFMD uses Impact Subsea's SeaView software for control, visualization and data collection.The ISFMD was supplied and supported by ECHO81, a U.S.-based equipment specialist for marine

on its EM 2040 MKII multibeam echosounder. The first enables the use of dual high frequencies to survey wide swaths of the seabed at much higher resolutions than before, while the second facilitates simultaneous collection of back scatter data using multiple frequencies.The EM 2040 MKII is a broadband multibeam echosounder system, which uses frequencies from 200kHz to 400kHz to yield a wide swath of up to 170 degrees. With the new high frequency feature, the EM 2040 MK II will additionally employ 600kHz and 700kHz frequencies to give enhanced detail over a swath of up to 120 degrees. This will
