EP42 equipped with Side Scan Sonar, 10 beam DVL and ADCP. Early this year, OceanServer delivered the

University’s third vehicle for service in the Great Lakes. The new vehicle will be used as part of the Great Lakes

Observing System Tributary

Monitoring project with funding from the Great Lakes Restoration

Initiative. The project looks at moni- toring five separate Areas of Concern across all five Great Lakes, using dif- ferent monitoring methods. The

University of Michigan’s part of the project will be using the Iver2 AUV for surveying Saginaw Bay, an Area of

Concern in Lake Huron. Researchers will use a Bottom Classification

Software with the sonar to support an on-going study of Cladophora growth that leads to unsightly and foul smelling muck on the beaches.

The new Iver vehicle will also be used for mapping fish habitats and reefs.

L-3 Klein’s new UUV-3500 prod- uct line leverages a powerful wholly

FPGA implemented - multi-channel processing engine. The sonar engine simultaneously optimizes two differ- ent - and concurrent - output data streams for: photo quality side scan imagery and high accuracy, co-regis- tered swath bathymetry. The UUV- 3500 operates exclusively with L-3

Klein’s proprietary wideband technol- ogy providing quality scan range and resolution in a low power, compact and lightweight payload. The swath bathymetry option allows for wide swath performance which is typically 10-12 times the overall altitude of the

UUV and thereby significantly greater coverage than can be achieved by a multi-beam echo-sounder.

A new addition to the Teledyne

TSS range of DMS motion sensors was launched at Ocean Business. The

DMS-500 range is being developed specifically to meet the needs of users who require a top-quality motion sensor with Ethernet connectivity, but do not require the subsea-rated housings that typify Teledyne TSS products. The result will be a com- plete range of conservatively-priced sensors that incorporate a number of advanced and innovative features for applications such as Dynamic

Positioning (DP), wave height moni- toring and structural stress monitor- ing. The versatile design means that the range will be available in various accuracies to make it suitable for a wide range of bespoke applications.

The first phase of the product’s launch introduces the Roll Pitch range of sensors including the DMS- 525RP and the DMS-535RP and

DMS-550RP, which were on view at

Ocean Business. These are designed to provide a reliable, accurate and cost-effective choice for motion measurement with roll/pitch accura- cies from 0.25° to 0.50° RMS with high dynamic accuracy during vessel turns. Unique features of the new sensor are the ability to provide power and data over Ethernet; and the inclusion of two independently configurable serial outputs - offering users a wide range of connection and application options.

PDM Neptec launched two new products at Ocean Business 2011.

The low loss Omicron Subsea Fiber

Optic Connector is high on perform- ance, yet low on cost. Rated for use to 5000 meters (mated), and designed for compact installations requiring minimum connector size,

Omicron incorporates proven ferrule carrier and alignment technology, producing insertion loss performance of <0.5 decibels at typical operational wavelengths with single or multi- mode fibers. The Compact

Quickcure Molding System (QMS) is a single slot, portable hotplate sys- tem for quick and easy cable splicing and repairs offsite. It comprises a sin- gle slot custom made mould heating block, Quickcure heater and temper- ature probe. Sachet based twin pack

Elastomers are available for use in custom made moulds which are sup- plied with a Peg Spanner and Mould

Drift for de-molding. The Compact

QMS heats up to the required tem-
