Singapore's Offshore Industry Recovering

, which may happen probably next year," he said. "They are slowly increasing their investment but not in a big way. Demand is still pretty slow."Growth in Singapore's trade-reliant economy had slowed in the wake of the oil price crash. It has since recovered as output in sectors like electronics surged, though economists say the city-state faces growing headwinds from a bitter U.S.-China trade dispute.Dwindling ContributionThe offshore and marine engineering industry's direct output contribution has more than halved since 2014 to about 1 percent of the city-state's economy, but

His previous roles include VP Finance at ALSTOM Grid where he was CFO for ALSTOM’s EPC business in the Asia Pacific region. Prior to ALSTOM, Liew also held key finance and strategy positions with SONY Electronics Asia Pacific Pte Ltd, and SingTel Ltd.Liew’s appointment completes Kreuz Subsea’s leadership team. He is the company’s fifth executive hire since AJ Jain took over the reins as chief executive officer in October 2017. In June, Jerry Starling joined as director of diving. In April

payloads to be mounted within minutes, without concern of payload shape, volume, or weight. Payloads have included salinity, turbidity, sonic velocity depth, various cameras, imaging sonar, release-able buoys, soil penetrometers, and electromagnetic sensor sleds, among others.Batteries and all electronics are included within the track volume maximizing free volume for the payload bay while minimizing “bottoming-out.” The wide track results in ground pressures of less than 1.3-kilopascal, when dry or 0.43 kilopascal when submerged. Track design can be modified for more aggressive grip

Both have the same Ethernet and serial data transfer as Torden.WiSub’s connectors use high-frequency microwave communication electronics to transfer data at high speed and use inductive resonance to transfer power, as they can coexist without interference. Using induction and microwave electronics also means the connectors have axial freedom and wide angular misalignment tolerances and don’t face wear issues – unlike

Robotics’ Operations Team from their California headquarters in Silicon Valley almost 9,000 km away and covered over 1,700km at sea.For this mission, Cefas’ Lyra was fitted with the new Simrad EK80 broadband echosounder with two transducers (200kHz and 70kHz), utilizing a version of the electronics that has been specifically designed for autonomous surface vehicles called the WBT Mini. The system was self-contained with its own dedicated battery and used in standalone mode. Lyra collected acoustic data continuously for 23 days on the organisms in the water-column at very high resolution

payload, running at peak efficiency gives the micro-UUV a range of a little more than 100 nautical miles in 33 hours. This presumed an operating speed of 3.0 knots. At 0.5 knots the same vehicle configuration could run for three days.In early 2018, Riptide announced a near-total redesign of internal electronics resulting in a new MKII µUUV. This offered a nearly 60% reduction in hotel load power to 3.8 Watts from its first-generation boards. It also reduced the internal wire count in the vehicle by 80%, simplifying the vehicle further. This traditional battery based performance is more than adequate

Nevertheless, companies including ABB, Siemens and Baker Hughes, a GE Company (BHGE), are working on solutions, by either marinizing already proven components (VSDs, switchgear, transformers, etc.) in one atmosphere containers, or creating and qualifying new components

reliable over multiple mating cycles since there are no dynamic seals that wear out, a far more forgiving mating tolerance, immunity to contamination and no pins to align, break or bend. A reduced mechanical complexity is valuable in increasing reliability, and justifies the application of solid-state electronics. There are further enhancements that an intelligent connector can provide which ‘simple’ pins cannot, such as localized network diagnostics.”   One of the vital breakthroughs that made the UAC concept viable relates to WiSub’s patented high-speed, high frequency
