Nautronix to Supply

DPR System for Rig

Nautronix won an order from HHI, Korea to supply a NASNet Dynamic Posi- tioning Reference (DPR)

System which will be used on the Bollsta Dolphin drilling rig. NASNet DPR is a position reference system for Dynamic Po- sitioning that also fea- tures the benefi ts of the

NASNet subsea acoustic positioning system and can be used either within pre-installed fi eld-wide

NASNet arrays, or as a localized positioning sys- tem. According to Nautro- nix, the system provides robust mitigation against many of the risks associ- ated with both acoustic and satellite position- ing systems, allowing multiple users to benefi t simultaneously from the same array with no risk of interference. NASNet DPR uses cutting edge acous- tic technology combined with a user-friendly inter- face to provide high speed position updates and stable positioning in wa- ter depths up to 4,000m. www.nautronix.com

Tritech StarFish for

Z-Boat 1800

The Oceanscience Group un- veiled the fi rst Z-Boat 1800 remotely-operated survey boat with integrated side scan sonar, from Tritech International. The new boat provides a shore opera- tor with real-time high defi nition side scan imagery from Tritech’s

StarFish 990F side scan on a por- table 1.8m surface vessel. The StarFish side scan is attached to a special skeg (keel fi n) under the Z-Boat, eliminating the need for a dedicated hull mounted transducer. In addition, the compact size of the StarFish topside box means that a single or dual frequency single beam echosounder can still be accommodated on the Z-Boat. Z-Boats with single beam echosounders are in operation around the world and can perform shallow water hydrographic surveys in natural and industrial water environments. www.tritech.co.uk

Insulated Wire Expands

Insulated Wire (IW) announced the ex- pansion of its capabilities to produce custom composite cables featuring low smoke/zero halogen polyurethane jack- ets. The company hasseen sales of these cables grow signifi cantly – particularly in naval applications, both on subma- rine and surface vessels.

IW’s composite cables provide a myri- ad of options. Components can include individually shielded and jacketed sig- nal transmission cables, power cables, microwave cables and fi ber optic. De- pending on the application, cables can be optimized to address issues such as hydrostatic pressure, tensile loads, concentrated compression points, etc. Over- all shielding can be provided with ferrous or non-ferrous materials. High per- formance, non-metallic braids and strength members, such as Kevlar are also available. The cable, shown with this release, was produced for a submarine application and contains multiple, individual signal cables and IW’s Tuf-Flex microwave cables for use at frequencies up to 18 GHz. Water block fi llers and binders are incorporated under a double braided Sn/Cu braid and polyurethane jacket. Cable withstands the anticipated environmental extremes in accordance with the method requirements of MIL-DTL-24643B par 4.8.8 and can withstand

Hydrostatic pressure up to 1050psi.
