Mooring Buoys

Mooring Buoys are used to keep one end of a mooring cable or chain on the water's surface. Designs for mooring buoys, like Polyform Mfr. are a traditional buoy with hardware or a buoy with a tube through the center.

A permanent mooring system, when properly designed, should securely position a boat so that it can be left unattended.

Flotation and will last for several seasons, depending upon the salinity of the water. A mooring system usually consists of a mooring buoy , a mooring anchor and a length of chain. Also the proper ground tackle includes correct sized galvanized and swivels.

Mooring Systems Inc.

About MSI For over a decade, Mooring Systems Inc. (MSI) has designed, fabricated, recovered and deployed , from buoy to anchor, great quality buoy systems and mooring designs for the international oceanographic community. The company expertise is firmly established in the fields of deep sea moored or bottom mounted instrument structures.

Their engineering and design programs continue to evolve. Computer modeling, materials research, the judicious selection of components and in house fabrication are all part of their effort to provide the best mooring systems possible. As custom manufacturers, they specialize in innovative designs and can accommodate any modification to meet individual customer needs. Flexibility and punctual delivery are MSI trademarks.

At Mooring Systems Inc. they take pride in having the level of experience that makes a difference. A strong academic background in ocean engineering, years spent on the technical staff of the Woods Hole Oceanographic Institution's mooring design group, and their demonstrated success as a worldwide provider of mooring systems have established MSI as a leader in this field. We have taken their designs to sea and deployed them. Mooring Systems Inc. know what works during computer simulation, and in a 40 knot North Atlantic gale.

It takes a skilled, reliable crew to successfully deploy a 15,000-foot long oceanographic mooring and we have all been part of such crews. The greatest lesson learned from shipboard experience is the importance of a simple, yet high-quality and dependable mooring system. At sea a failed component often leads to a lost mooring. You will not find a weak link here at MSI.

Meteorological Buoy

Built for the Marine Optical Buoy project off Lanai, HI. This is an excellent example of a custom tower surface buoy engineered and designed to accommodate diverse instrumentation by MSI.

Marker Buoy

The MSI Marker Buoy series is built to be simple and cost effective. The basic design consists of Surlyn foam flotation sandwiched between two galvanized steel plates. A galvanized steel threaded rod or rods provide structural integrity between the large upper lifting bale and lower mooring eye. The Standard features include a tensile strength of at least 5 times the buoyancy, self-fendering flotation collar and large pick-up bail. Custom instrument components, colors, sizes and shapes are available upon request.

Surface Buoys

Mooring Systems' line of MSI Surface Buoys offers a broad scope of features and options to meet the needs of the oceanographic community. Standard and custom constructed buoys incorporate the outstanding properties of Surlyn foam flotation collars. The basic design consists of a cylindrical hull with or without chines, a central well, a footed base and a tower. Standard options include solar panels, custom sensor and instrument mounting brackets, multiple instrument wells, antifouling paint and stenciling.

The Company have proven to be rugged and reliable in the harsh offshore environment as well as resilient and cost-effective in shallow water locations.
