A web-eye for maintenance


Navigation equipment manufacturer Alphtron Marine has developed a headset for onboard crew, which lets them share what they are seeing with a shore-based expert. In effect, it provides an extra pair of eyes to help with onboard fault support. AlphaEye transmits audio and video over a dedicated (satellite, 3G or 4G) communication link directly with support personnel at Alphatron Marine’s headquarters. This telepresence makes troubleshooting considerably more straightforward as crew waste less time trying to describe the set-up, while the remote staff can offer clearer instructions to resolve a particular issue, even with heavily customised onboard environments. While intended primarily to

support Alphatron equipment, the web-eye could be used for remote assistance in other onboard situations or emergencies.


Water treatment gets shrunk

ALFA LAVAL: Boasting a smaller installation footprint and reduced investment cost, equipment manufacturer Alfa Laval has introduced PureNOx Prime: a redesigned water treatment system for engines using exhaust gas recirculation (EGR) to meet US Tier III NOx limits. With the implementation of

Tier III sulphur limits for the North American and US Caribbean control areas approaching, Alfa Laval says the re-use of exhaust gas is “a technology front-runner due to its significant space savings and low total cost of ownership”. Water treatment is a crucial part of the EGR process.

time period for instant replay ashore, saving valuable time in responding to an incident. Service technicians or ship managers can remote in to the shipboard hardware while at sea to collect data samples and perform diagnostics in preparation for mandatory annual performance tests (APTs). In this way, they can ready the appropriate tools and spare parts to meet the ship on

arrival at port. In addition to pulling data from

Alfa Laval’s original PureNOx technology was developed in close co-operation with MAN Diesel & Turbo and tested aboard vessels from the Danish boxship giant Maersk. PureNOx Prime is said to pack the same perfor- mance as the original into a smaller footprint, thereby reducing lifecycle costs.


Remotely peeking into blackboxes

DANELEC MARINE: Danelec Marine has introduced a PC software tool that facilitates remote selective data downloads from shipboard voyage data recorders (VDRs). VDR OnDemand allows shore offices to log on via an internet link and request data from a vessel’s VDR . In the event of an onboard

incident or emergency, the ship manager can request transfer of recorded VDR data for a given

a vessel, the company is develop- ing a range of ‘push-through’ solutions for automatic down- loads of recorded data from the VDR and connected sensors and systems at pre-selected intervals.


Painting a picture of fuel savings AKZONOBEL: AkzoNobel’s marine coatings brand International has launched a fuel calculator that is said to provide accurate and transparent

predictions on the fuel and CO2 savings potential of fouling control coatings prior to application. “When selecting a hull coating for a vessel, having an accurate understanding of the return on investment prior to purchasing is essential,” said project lead Michael Hindmarsh. Intertrac Vision was four years

in the making and involved collaboration with leading academic and commercial research institutes, including the University College London (UCL) Energy Institute, MARIN, Newcastle University and some 30 shipowners and operators. The tool combines an understanding of total hull roughness (micro and macro) and ‘roughness’ associated with biofouling together with findings from CFD studies on different hull

forms to predict the impact of fouling-control coatings on the comparative powering require- ments of a vessel. The calculator uses hundreds of thousands of datasets, which, say its creators, makes it one of the shipping industry’s first Big Data solutions. Tristan Smith from UCL’s

Energy Institute said: “While hull coatings manufacturers have long offered insight into the fuel and CO2

saving potential of their

solutions, ship owners have maintained a degree of scepticism around performance prediction. The lack of accurate and transpar- ent supporting data underpinning statistics quoted has contributed to this mindset.”


Reeling in fish bombers SA INSTRUMENTATION: A Scottish technology company is on a mission to prevent fishers in Malaysia from bombing their catch out of the water. This rather unconventional method of harvesting fish endangers the coral reefs in the Sabah region of Malaysia. St Andrews Instrument- ation of Tayport, Scotland, was called in to develop a bomb listener to better locate the fishers. The device provides authori-

ties with co-ordinates of the fish bomb blast in almost real time, increasing the probability of those responsible being apprehended while they are collecting the fish. The overall aim of the plan is to deter fishermen from using bombs as a quick and easy way of boosting their catch. SA Instrumentation operations

manager Richard Baggaley said: “The biggest challenge was to design a product that could listen for bombs from multiple locations and determine the approximate GPS location of the explosion. It was also necessary for it to work over long distances.”
