s Moorings

AXYS has been designing, building, deploying and recovering moorings on a wide variety of instrumentation and buoys in lakes, rivers, coastal and deep offshore oceanic waters for 35 years. AXYS holds an extensive library of proven mooring designs developed in-house and from other oceanographic institutes around the world.

Design, Testing & Modeling

Optimum design of a mooring is dependent on several factors, including functional requirements, water depth, currents, tides, waves, vessel traffic, fish bite, deployment logistics, anchor requirements, etc. Ensuring the buoy has sufficient buoyancy under maximum conditions is a critical component in the design.

All mooring designs are analyzed with numerical models and modeled with dynamic simulation software that confirms their operational performance. These mathematical techniques, sound engineering practices, and years of experience to select the best mooring materials, result in long-life, reliable moorings. Our designs have been proven in very aggressive environments across the world, and consideration is specifically given to durability of the mooring within a range of environmental challenges.

Mooring Wear & Maintenance

Moorings Moorings will wear differently depending on many factors including, waves and currents, fish bite, biofouling, and boat or fishing accidents. For optimum performance over time, AXYS can recommend a best practices maintenance plan in order to help increase the Mean Time Between Failure (MBTF) of your mooring. The AXYS Services team has participated in the annual service cruise for the Environment Canada Weather Buoy network on the west coast in 1985. Find out more about the mooring maintenance procedures conducted on these cruises in our webinar here.

s Custom Projects

Many of AXYS’ standard products are customized to meet the client’s specific monitoring requirements, however occasionally AXYS gets a request for an altogether new monitoring solution that requires an innovative custom design.

Custom NOMAD Instrumentation Buoy

Following a thorough analysis of the project’s monitoring requirements, AXYS will design a system that meets all the criteria. Rigorous project management and quality assurance methodology are followed according to an established process in order to ensure that the final system meets the client’s needs. The AXYS Services team is able to provide training on every system delivered, as well as commissioning and deployment assistance.

Examples of some custom monitoring solutions include:

Wave Energy Testing Instrumentation Buoy

To help Northwest National Marine Renewable Energy Center at Oregon State Univeristy reach their goal of an offshore mobile wave energy testing facility, AXYS partnered with them to design a new buoy – the Ocean Sentinel Instrumentation buoy. AXYS engineers worked with NNMREC staff to develop this custom buoy system that interfaces with numerous custom control and monitoring devices, as well as basic meteorological and oceanographic parameters. The system also provides real time communications that monitor all aspects of the system performance.

Sub-Surface Environmental Monitoring 

AXYS has provided sub-surface environmental monitoring systems for a variety of challenging marine environments. With an array of sensors, including temperature, dissolved oxygen, and water chemistry, data can be transmitted to a surface buoy for processing using an acoustic modem or an inductive mooring line. Two-way communication capabilities allow remote system management, including configuration and diagnostics of both the buoy and the mooring components. Sub-surface moorings are easily recovered using acoustic releases, which can be triggered at any time, allowing the instrumentation to float to the top and leaving the anchor on the seabed.

Other examples of custom projects: 

  • HydroLevel Buoy for NAVOCEANO – portable and flexible GPS buoy for water level measurement
  • Arctic Lake Monitoring System – year-round monitoring of arctic lakes using a buoy and sub-surface mooring.
  • Water Quality Buoy for Environment Canada – automated water quality data collection.
  • WatchMan500 for University of New Hampshire – detect, model and forecast changes in the ecosystem.

 

s Water Levels and Tides

Monitoring water levels, tides and their currents is an important field of study for many applications, including ship navigation and port operations, government defense, coastal zone engineering projects, ecological studies, and even commercial and recreational fishing.

HydroLevel Mini Buoy

Traditional tide and water level monitoring uses shore-based tide gauges. The limitations to this method include availability of the land when there are permitting, operational, safety, and security challenges. If onshore tide gauges are not available, a combination of techniques such as tidal constituents databases, tidal zoning and hydrodynamic modling produce estimates of chart datums and tide correctors. This modeling is based on best available information and due to this uncertainty of model input, the water level error can be 40-60% of the total depth solution.

AXYS has developed an electronics payload using  DGPS to accurately monitor water elevation in any body of water where a surface following buoy can be deployed. In addition to position measurement, a motion sensor on the buoy measures the pitch, roll and heading of the buoy in real time. This data, along with earth tide corrections are supplied to the buoy’s processor, which performs tilt corrections, averaging and filtering. It enables depth positions to be measured on the absolute three dimensions and eliminates the need to estimate water levels The AXYS HydroLevel™ technology is available on many buoy platforms, enabling the system to be used in differing environmental conditions.

s Offshore Wind Resource Assessment

The need for accurate offshore wind data is growing rapidly worldwide. Wind farm developers and financers understand that accurate wind data is critical to the overall success of the site, not only in assessing the potential power of the location, but also in the positioning of the wind turbines.

WindSentinel Floating LiDAR

The traditional approach for gathering wind data is to construct a meteorological mast equipped with anemometers. However, in the offshore environment this practice is both difficult and expensive to implement. Floating LiDAR technology is an innovative solution to these problems. The AXYS FLiDAR WindSentinel™ buoys use a LiDAR to measure wind at turbine hub-height to provide accurate and reliable data on wind speed, wind direction, and turbulence. Additional sensors can be integrated onto the buoy to achieve a full environmental assessment of the location.

s Metocean Monitoring

Metocean monitoring is an important field of study for many applications including, weather forecasting, climate studies, operations & safety, resource assessment, maritime safety and marine domain awareness, among others.

NOMAD Met Ocean Buoy

Typical ocean and coastal monitoring buoys gather data on wind speed and direction, waves, currents, atmospheric pressure, air temperature, water temperature, and relative humidity to  measure a variety of meteorological, oceanographic and water quality parameters. Data is acquired, processed, logged and transmitted via radio, cellular, or satellite telemetry to the end user. Many buoys provide the dual function of automated weather station and navigational aid. Deployments can be in various locations, from calm, shallow waterways to 5,000m depths in open ocean. Buoys are typically powered by solar panels and rechargeable batteries, which enable them to remain deployed for long periods of time.

AXYS offers a variety of metocean buoy systems to meet specific monitoring requirements and environmental conditions. Custom mooring design, telemetry communications, and data hosting services are available, as well as commissioning and deployment from our experienced services team.
