Vessel Traffic Safety

APPLICATION: Vessel Traffic Safety in the Port & Harbor Environment

Access to accurate, real-time current and wave information is a critical component of Vessel Traffic Safety (VTS) operations in the port and harbor environment. Teledyne RD Instruments Acoustic Doppler Current Profilers (ADCPs) and multi-directional Waves Array products are ideal tools for this environment, offering highly reliable environmental data when and where you need it most.

ADCPs in the port & harbor environment

Why do you need current and wave data in the port and harbor environment?

Improve Port Efficiency
As shipping vessels become larger, time windows for port entry and exit become smaller. The key to moving more ships is to know what’s happening with the waves and currents. Real-time wave and current information puts an end to reliance on tide predictions and uncalibrated models, resulting in larger windows of operation, improved efficiency, and lower costs.

Bottlenecks cost money. Demurrage fees add up quickly when ships are waiting offshore or inside a port. Real-time current and wave measurement solutions from Teledyne RD Instruments can help reduce these costs.

Ensure Vessel and Personnel Safety
Large vessels operate with minimal under keel clearance, which means safe port operations require accurate current information to understand the true under keel clearance from excessive vessel squat. Accurate wave information is crucial for predicting extreme vessel pitch and roll, which can cause potential groundings. Sending a ship out when the tides are wrong (a decision too often based on imprecise models and predictions rather than on solid, real-time data) can result in a costly incident.

Enhance Security
Precise knowledge of a port’s currents can enhance security operations by helping to predict the effects of a contaminant spill and by predicting likely methods of attack by SCUBA equipped terrorists. Whether a contaminant is released deliberately or as a result of an explosive attack, the need to know where that contaminant will end up is paramount. Any model that attempts to predict this must have up-to-date and precise current data. Without it, there’s no telling where contaminants will end up,and damage control resources will not be as effectively applied.

Where are Teledyne RDI ADCPs being used?

Teledyne RDI’s ADCPs and waves measurement products are hard at work collecting data in ports and harbors around the globe. Two specific recent examples include:

Port Kembla, Australia
At Australia’s Kembla port, the pilots were asking for wave and current information. Port managers answered by giving them data from two Teledyne RD Instruments ADCPs. Pilots now receive real-time wave and current data, information that has helped them operate safely, especially at night.

Rotterdam, The Netherlands
In an effort to widen the port ’s operating windows,managers at Rotterdam installed a Teledyne RD Instruments horizontal ADCP. The real-time data is also being used to improve safety as ships are required to make a sharp turn into the harbor at slow speeds, a situation in which current speed plays a big role.

Teleyne RDI ’s Product Solutions:

  1. Workhorse 300 kHz Horizontal Acoustic Doppler Current Profiler (H-ADCP) with optional Waves Array looks out horizontally from its mounting structure to measure near-surface water currents and multi-directional waves out to 200M ranges. The H-ADCP can be placed at the port entry to measure currents and waves in the harbor approach channel, or variations of the currents across the navigation channel.

  2. ChannelMaster Horizontal ADCP (H-ADCP) provides critical horizontal current information for short range applications such as vessel docking.
  3. Workhorse Acoustic Doppler Current Profiler (ADCP) collects internally logged or real-time information about the vertical variation in water speed and direction. The flexible, bottom-mounted Workhorse platform can be upgraded to include multi-directional wave measurement capability.
