n innovative new wire- less subsea modem has been trialled at the Underwa- ter Centre in Fort William, Scotland. WFS Technologies – the
world’s leading supplier of wireless technology for un- derwater communication, navigation and power transfer – trialled the Seatooth S100, a mobile, wireless subsea modem suitable for a variety of underwater applications from 100 – 4,000m. The modem can provide a
reliable digital wireless com- munication link or logging device up to 5m range, even in challenging deepwater condi- tions.
It is equipped with stan-

dard data communication in- terfaces, making it suited to sensor and underwater vehi- cle applications. It can be deployed swiftly
on temporary or permanent installations to support safety and efficiency in a range of subsea applications including data logging, upgrading sub- sea equipment and wireless backup.

Monitor for safe transfers O
SIL has launched a Ves- sel Motion Monitoring System (VMMS), designed to increase safety of transfers during offshore wind farm operations.
With a second generation 6 DoF (Degrees of Freedom) motion sensor, the VMMS monitors safety thresholds for heading, heave, pitch, roll, sway and yaw. The portable, battery
powered monitoring system has a removable hard disk for data retrieval, and is pro- grammed to display a red sig- nal to indicate when it is unsafe to transfer because safety thresholds have been exceeded. The Vessel Motion Moni- toring System’s safety thresh- olds are customisable to
34
customer’s specific operations, ensuring that transfers are only made under the green light.
Richard Williams, managing director of OSIL, said: “We are excited to expand our product portfolio with our state of the art Vessel Motion Monitoring System. The transfer of wind farm technicians to the wind turbines has inherent risks, which we are looking at improving with our new monitoring system. Rather than having to make a sub- jective decision, users can now make informed, scien- tific decisions on safety measures.”
pany’s decision to test the new Seatooth S100 at Fort William was the Underwater Centre’s 1.5 million litre in- door seawater tank which al- lowed the WFS team to both observe and monitor their equipment in one location without tidal drift.

OSIL’s Vessel Motion Monitoring System
onardyne Asia will be pre- senting a new automatic leak detection sonar to the Asian Off- shore industry at OSEA 2012. The Automatic Leak De- tection Sonar (ALDS) is de- signed to continuously monitor one billion cubic feet of water for leaks around sub- sea oil and gas assets. Capable of 360° coverage, it can detect leaks at rates of less than one barrel per day at ranges in excess of 500m in deep water. Sonardyne’s Autonomous Monitoring Transponders (AMTs) and GyroUSBL will also be on display. AMTs are designed for long
endurance data collection whilst Lodestar GyroUSBL requires only an initial calibration, en- abling significant savings in ves- sel time and operational costs.
