Gothenberg, Sweden based Humphree was founded in 2002 by a team of engineers that sought to leverage their expertise in high-speed marine propulsion – or more specifically, hydrodynamics, electronics and digital controls – to create vessel stabilization packages that would be easy to install and use. And thus, Humphree’s interceptors were created.The compact and robust transom-mounted units feature an adjustable blade that activates vertically into the water stream beneath the hull to create a lift force.

For the monitoring of gas turbines: the new acceleration and pressure sensors, plus fitting charge amplifiers from Kistler (Photo: Kistler)

Kistler has introduced what it says is world’s first high temperature accelerometer for the monitoring of gas turbines. Designed for long-term use at up to 700° C, the piezoelectric sensor – made in Switzerland – is not pyroelectric and does not show any popcorn effect, offering manufacturers and operators of gas turbines new options for monitoring the combustion stability.The efficient and secure operation of gas turbines relies upon stable combustion processes. These have to comply with increasingly strict regulations, including flexible operation on different fuels and minimal emissions.

AB Marine To Distribute Gobius Tank Monitors

AB Marine of Rhode Island has been selected to distribute Gobius Tank Monitors in the U.S. and Canada. Sweden-based Gobius recently introduced the Gobius4, an outside-the-tank monitoring system that requires no holes to be drilled for mounting. The Gobius Technology system consists of a shaker and an accelerometer. It is best described as “knock and listen”, to measure fluid levels in all types of tanks. The sensors are mounted outside the tank so no holes need to be drilled. Unlike other tank monitors, the Gobius4 can be used on aluminum, plastic, stainless steel or fiberglass tanks of any shape and size. The control head maintains all of the calibration data even when the system is switched off so there are no worries about accuracy or reliability.

Seacoaster Merges Surface Effect Ship with Catamaran Design

Air Ride Craft, Inc., Miami, has developed a new marine vehicle that promises to revolutionize the fast-craft industry. The Seacoaster combines the best features of the Surface Effect Ship (SES) and the catamaran. The vessel is the subject of extensive ongoing patent efforts both in the U.S. and internationally. It is applicable to all manner of marine craft markets including commercial and military. · Offers pricing comparable to other craft due to its simple low cost design. The first of these new vessels will go into service on Lake Erie this summer as a 44 knot, 150-passenger ferry for Island Express Boat Lines Ltd., Sandusky, Ohio. The passenger ferry, called Island Rocket II, is depicted in an artist's drawing in Figure 1. The 72 ft.
