Kongsberg GeoAcoustics has unveiled its new compact survey vessel (CSV), which is designed to help survey shallow coastal and inland waterways quickly.

The CSV features a manoeuvrable two-person catamaran and is equipped with the latest GeoSwath 4R shallow water simultaneous swath bathymetry capability and side-scan system.

It has been specially designed to be transportable in order to facilitate launch and recovery operations in even the most remote locations.

The lightweight craft can be launched by one person and features ergonomically designed instrument controls, communication systems and survey operating tools.

Kongsberg’s new CSV is made from plastic with all stainless steel fittings and measures 3m in length and 1.62m in width. The 182kg vessel is powered by a 30hp outboard engine.

The CSV offers a standard fuel capacity of 24L and is capable of cruising at a top speed of 27k from a launch site to survey area.

In addition, the vessel has a draft of 0.35m, which allows it to operate in extremely shallow environments. It can also quickly map bathymetry and record geo referenced side-scan data using the GeoSwath 4R system.

"The CSV offers a standard fuel capacity of 24L and is capable of cruising at a top speed of 27k from a launch site to survey area."

The vessel’s GeoSwath transducer is mounted on a retractable pole with pre-installed motion sensor, GPS heading and position system and sound velocity sensor, while the operator uses a console mounted ruggedised laptop to plan and control the survey.

It can be used in both marine surveys and on canals, rivers and lakes due to its shallow draft, high top speed, manoeuvrability and the stability of a catamaran hull.

According to Kongsberg, the new GeoSwath 4R system provides enhanced productivity in shallow waters with at least 12 times the water depth coverage right up to the waterline, complying with the requirements defined by the International Hydrographic Organisation’s performance standards for bathymetric data.

The GeoSwath 4R system also includes various advanced capabilities, including a feature filter for automatic filtering of vertical structures, as well as a new user-friendly graphical user interface with an initiative design, among others.
