Norway-based Kongsberg Maritime has delivered a new CCTV system for installation on to the US Coast Guard's (USCG) heavy ice breaker vessel, Polar Star (WAGB-10).
It comes after the successful incorporation of a CCTV system on Polar Star's sister vessel, the USCG Healy Polar ice breaker, in 2013.
Kongsberg's CCTV range features an in-house design with modified off-the-shelf (MOTS) video camera stations, telemetry and control components.
The cameras fitted on the Polar Star are made of stainless steel and equipped to combat harsh weather, as well as adapt to extreme low temperatures.
The system's components meet naval specifications to adapt to shock, vibration, electromagnetic interference (EMI), temperature, and humidity. It can be deployed in adverse marine environment.
The CCTV system is comprised of a range of marine-grade camera stations with static cameras equipped with zooming capability, and one pan, tilt and zoom (PTZ) camera in the deck locations exposed to the external climate.
Fitted with high-resolution low-light colour / mono sensor with 18x optical zoom, the cameras also feature an integrated wiper system.
The below deck is monitored by a series of high resolution varifocal colour dome cameras with in-built IR illumination, facilitating its operation in low-light conditions.
It is expected to enhance video image quality, offering more flexible control, power conditioning, viewing, recording options, and increased hours of operation in adverse marine environments.
The images, after being generated, are spread across the vessel via a large video matrix, and the cameras can be controlled at telemetry keyboards with three axis joystick controls.
Kongsberg will also provide local assistance during the commissioning of the CCTV system.
Last year, Kongsberg deployed its OE14-530 3DHD underwater video camera to generate images during an expedition to survey the historic World War II shipwrecks of HMAS Sydney (II) and the German raider HSK Kormoran, off the coast of Western Australia.
