The consumption of expensive standard seawater is great- ly reduced through a standardization technique which allows the standard sample to be reused for many meas- urements. The dual cell approach removes the need for highly stable bath temperatures since both cells are sur- rounded by a well stirred oil bath to ensure thermal uni- formity. This ensures that sample properties needn’t be changed by warming to match the salinometer, making it ideally suited to CSIRO’s requirement to calibrate over a range of temperature.

Schilling HD ROV Targets IMR, Drill

Support Markets

Schilling Robotics launched the HD Remotely

Operated Vehicle (ROV). Schilling’s 125shp HD system is currently completing deepwater sea trials and two HD systems have been ordered for delivery this year. The HD employs Schilling Robotics’ technology to bring a high performance work-class ROV system to the market that has a compact deck footprint, while providing design fea- tures and performance normally reserved for larger sys- tems.

The HD is designed for accommodating the specific needs of the Inspection, Maintenance, and Repair (IMR), drill support, and medium-duty construction markets.

The HD features Schilling’s power management system, remote diagnostics, and advanced automatic piloting modes that deliver superior operational stability and prec6utise control. Based on integrated sub-systems, the

HD is designed to reduce complexity, increase efficiency, and lower the cost of owning and operating an ROV. The

HD includes dedicated interfaces for integrating interven- tion or survey tooling. Ergonomic and modular system design provides users with spacious access to the system for rapid maintenance, and a large onboard capacity for installing additional intervention tools. Combined with

Schilling’s electric TMS system, the HD is capable of excursions up to 425m. www.Schilling.com

New Underwater Positioning System

Kongsberg Maritime has a new range of acoustic underwater positioning systems and transponders, designed to harness the power of 'Cymbal', Kongsberg Maritime's new sig- nal processing protocol while also being backwards compatible with the HPR 400 proto- col and analog transponders. In addition to a new family of transponders called cNODE, new systems include HiPAP 501/451/351/351P, which are the second generation of

Kongsberg Maritime's acoustic underwater positioning system and are designed to offer improved position accuracy, longer range capability and faster data telemetry. The new cNODE series of transponders consists of three models: Maxi - a full size transponder with large battery capacity, floating collar and release mechanism, and long life operation, designed primarily for seabed deployment. Midi - a short transponder with good battery capacity perfectly suited for subsea construction work and Mini - a small transponder for

ROV/AUV mounting and subsea construction work. cPAP, a new compact subsea trans- ceiver, designed for ROV positioning is also part of the new transponder family. www.kongsberg.com
