New Robot Can Sense Plankton Optically and Acoustically

A team of biological and physical oceanographers and engineers have modified a common physical oceanography instrument to be able to image zooplankton as it glides through the ocean.The robot, a first-of-its-kind sensing instrument dubbed Zooglider by Mark Ohman, a biological oceanographer at Scripps Institution of Oceanography at the University of California San Diego, uses as its platform a Scripps-developed glider known as Spray. Ohman and Scripps instrument developers outfitted the torpedo-shaped Spray gliders with a camera (called Zoocam) and a device researchers call Zonar that gathers acoustic

An Industry in Change

“What can we do differently?” The resonating question that over the last decade has reshaped a historically slow-moving industry into the fast-paced, innovation driven, entrepreneurial community we see today. By removing monopolies and making space for new concepts, we have seen smaller start-ups fast become leaders in their field. Today, both long established companies and newcomers alike must find the right a balance between innovation and reliability to thrive in an increasingly competitive space. I spoke with two companies – an established adaptor and one of the most successful

ADCP-based Monitoring System Aids Operations in Darwin Harbor

Near real-time data assist mariners navigating strong and complex currents   Located in Australia’s northern Top End, the port of Darwin has long been a strategic gateway to/from Asia. Founded in 1869, today Darwin is a major multi-modal port serving shipping and cargo markets. Ships range from container and general cargo to cruise and naval vessels. Exports include livestock and minerals as well as bulk liquids like LNG. As well, the port provides services for offshore oil and gas rigs.   Due to Australia’s increasing trade links with Asian neighbors, the port and facilities

HYPACK Offers Barge Management System

HYPACK now offers a solution to track multiple vessels and share the information across vessels. It also allows any remote viewer with a web browser to observe the survey or construction operations on their PC, tablet or cell phone.   Secondary vessels (tugs) are equipped with a Wi-Fi broadcaster which takes their network GPS feed and sends the messages to the Primary vessel (barge). Optional antennas can increase the range from 2km to over 10km.   Tugs can then receive their own Area Map showing all vessels using a Web Browser, or have additional controls for anchor handling and targeting

Designing an HD Camera Platform for the Future

April 2015 will see Imenco bring its latest camera platform, the SubVIS Orca, to market. This will feature HD over Ethernet compatibility. For the last 10 years, most cameras have operated by capturing a digital image and converting it into an analogue composite video signal for subsequent transmission. At the surface this signal is displayed onto a monitor. Some alternative systems reconvert this back into a digital signal (either inside or outside the camera), and send it up the umbilical. The digital signal is then fed into a PC and viewed on a monitor. Three years ago, Imenco reviewed the

, particularly shipping containers and vehicles to help keep tabs on the whereabouts of their cargoes.    The Waterloo, Ont.-based company will provide hardware and software support for cloud-based communications boxes built into shipping containers.   Each device will include a cellular radio, Wi-Fi connectivity, a microprocessor and sensors that monitor what's in the container, its location and other details to help fleet managers stay on top of their products and anticipate potential problems. The communication box is very similar to a cell phone, except it doesn't have a display

Rayotek: Seeing Under Pressure

Rayotek & Safer Viewing of Hostile Marine Environs According to Bill Raggio, Rayotek Scientific isn’t specifically a maritime company, but it definitely is part of San Diego’s “Blue Economy.” “We’re both an engineering company and a sapphire and glass manufacturer. We makes specialized glass for windows and sight windows, diffusers, pressure vessels, hydraulics and boiler systems, submarine periscopes and camera covers,” says Raggio, Rayotek’s chief technology officer.  “Spacecraft and submarines both require windows that can take

Rogue Waves

Ever since man has taken vessels onto the seas, mariners have reported encounters with monstrous waves that seem to arise out of nowhere from an otherwise average sea state.  On his third voyage to the New World in 1498, Christopher Columbus recorded in his logbook that a giant wave lifted up his vessels as they transited the waterway between the Paria Peninsula of Venezuela and the island of Trinidad, a waterway he then named Bocas del Dragón (the Mouths of the Dragon).  In 1853, the ship Annie Jane carrying 500 emigrants from England to Canada was struck by a monstrous wave off the

Underwater Metal Detectors for Law Enforcement, Commercial Diving

Commercial diving companies and law enforcement agencies are acquiring underwater metal detectors to help in their search and recovery operations. Designed for use in the subsea environment, these detectors have a minimal number of controls making them easy for divers to operate. They are an essential piece of equipment for locating and tracking pipelines, searching for lost tools and equipment, pinpointing the position of anchors and moorings, as well as finding weapons, evidence and explosives. New Jersey based Randive is one of the diving companies employing underwater metal detectors in their

USV Powered by Renewable Energy

Eco Marine Power (EMP) today revealed details of its Aquarius Unmanned Surface Vessel (USV) and announced that it will begin work related to the construction of a prototype. The Aquarius USV is being developed as a cost-effective unmanned surface vessel (USV) and will incorporate a number of technologies from EMP and its strategic partners. These technologies include marine computer systems and lightweight flexible marine solar panels. The Aquarius USV will be powered by a solar-electric hybrid marine power solution which will also feature a solar panel array designed by EMP. Onboard batteries will
