Intelligent wireless bolts in wind turbines or satellites may be able to let the operator know when something is wrong
Intelligent wireless bolts in wind turbines or satellites may be able to let the operator know when something is wrong

In the future, intelligent wireless bolts in wind turbines or satellites may be able to let the operator know when something is wrong. This could reduce the risk of human injuries and save cost.

A research team at NTNU in Gjøvik is working to create bolts that send an alert when something is not as it should be or when maintenance is needed. Each bolt must be able to contact a control center, which will receive messages from all intelligent bolts of this type in all installations around the world.

The team working on these wireless bolts includes Professor Michael Cheffena, two fellows and the manufacturer Dokka Fasteners. The vision of the research team is to develop wireless sensors to be installed inside the bolts. If the sensors detect that something is Continue reading “Are ‘Smart Bolts’ the thing of the future?”

Heinen & Hopman have launched new CFD-analysis service to reduce HVAC costs

Marine HVAC supplier Heinen & Hopman has introduced a new service that can accurately predict where deficiencies in an HVAC system may occur before mounting a single piece of equipment on board a vessel.

According to Heinen & Hopman, computational-fluid dynamics (CFD) technology is used to analyse the HVAC-system design to validate whether the HVAC installation shall meet specific requirements.

In a recent press release, Heinen & Hopman outlined, “CFD is a well-established technology in many industries. With CFD technology, airflows can be realistically simulated to identify common HVAC problems, such as drafts, high levels of turbulence, high-pressure drop[s] and poor air-distribution. CFD considers everything from Continue reading “Heinen & Hopman launches new CFD-analysis service to reduce HVAC costs”

Liquid nitrogen and heat system could meet new rules on emissions

Posted on by News Hound

Perryman Technologies is developing what it believes is the marine power source of the future – a source of powering marine engines that do not rely on combustion and does not result in any harmful emissions. Instead, steam, gas turbine can be powered by heat and diesel engines can be powered thermal energy, heat, stored as molten metal, combined with liquid nitrogen or highly compressed air.

Spokesman Shiva Vencat says the Perryman battery system is timely, considering the IMO has just agreed to cut emissions by at least 50 percent by 2050. He also cites Wood Mackenzie’s prediction that global shipping fuel costs are likely to rise by a quarter in 2020 when the global sulfur cap takes effect.

Martek Marine provides superyacht D-Fence from drone threat

The superyacht fraternity are waking up to the growing threat that drones pose to privacy, safety & security on-board their yachts. Recent years have seen a massive advance in drone endurance, range and payload capacity whilst the price has also plummeted, leading to a proliferation of drones expected to reach 12 million by 2020.

Terrorist use of drones deploying explosives and poison gas attacks are well documented. The potential for a drone to deliver an explosive charge or even payloads such as nerve-gas on-board a superyacht is a stark reality. Paparazzi intrusion using drones approaching superyachts is already a recognised and growing problem. Yachts in port, at anchor or on coastal transits are simply ‘sitting ducks’ and currently powerless to know if/when they’re going to be attacked, let alone be in a position to defend against the threat.

To combat this emerging threat Martek Marine have Continue reading “Martek Marine provides superyacht D-Fence from drone threat”

ClassNK publishes guidelines for use of drones in class surveys

Leading classification society ClassNK has released its Guidelines for Use of Drones in Class Surveys. These guidelines incorporate the applicable range and procedures for use of drones in class surveys, the technical considerations for safe operation and the requirements for drone service suppliers.

Because drone-related technologies are improving at an extremely rapid pace, application in diverse fields is increasingly expected. In the maritime industry as well, efforts aimed at utilization in the field of inspections and surveys are being carried out.

At the International Association of Classification Societies (IACS), discussions on the use of Remote Inspection Techniques (RIT) including drones in class surveys are already underway, and IACS Rec. 42 (Guidelines for Use of Remote Inspection Technics for Surveys) was revised in June of 2016. A revision of the related IACS Unified Requirements has also been completed and will take effect in January 2019.

On the other hand, when flying a drone in places such as Continue reading “ClassNK publishes guidelines for use of drones in class surveys”
