Teledyne Bowtech: Lamps for the Five Deeps Expedition

to design a bespoke lamp, designed to operate in up to 11,000 meters of seawater and with a lumen output of 15,500. Designed to also meet Triton’s input voltage specification, the lamps were supplied oil filled with individual compensators. The main challenge was the right selection of lamp electronics to ensure that they would be suitable for long-term submersion in oil and were able to withstand the 1100 bar pressure whilst remaining fully operational. In order to achieve all of the above, significant and considerable analysis and testing was conducted to ensure suitability and reliability

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

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

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
