Mooring and anchor pendant buoys
Foam-elastomersurface buoys by Hippo MarineHippo Marine manufactures buoys in the same way as they manufacture their foam-elastomer fenders. The production method is identical and so are the materials used. As a result, Hippo Marine buoys are extremely capable of absorbing the impact of a vessel, making them ideal for all sorts of marine operations.
Because the buoys are manufactured from closed cell polyethelene foam, the buoys are virtually unsinkable, even if the protective polyurethane skin is severly damaged.
For offshore operations, this provides a tremendous advantage over rotary moulded polyethelene buoys, which basically are hard shell buoys, which might be filled with (usually) polystyrene foam afterwards. Breach of the skin, will result in loss of buoyancy and eventually loss of the buoy (in particular if the buoy is not filled with foam).
Hippo Marine manufacturers a number of buoys typically used for offshore applications:
- Pickups buoys - typically 100 kg nett buoyancy
- Chain support buoys - typically between 900 and 5454 kgs nett buoyancy
- Chain through buoys - typically between 900 and 5454 kgs nett buoyancy
- Cylindrical anchor pendant buoys
- Square anchor pendant buoys
- Rectangular anchor pendant buoys (Suitcase type) - up to 20.000 kgs reserve buoyancy
Subsurface buoyancy
Next to their range of surface buoys, Hippo Marine also manufactures and supplies subsurface buoyancy. Depending on rated water depth, Hippo Marine selects the proper foam for the project (e.g. PVC, PU or syntactic foam).
Hippo Marine can machine the subsurface buoy in virtually any shape in their 5-axis router.
Typically subsurface buoyancy is required for offshore related operations:
- ROV umbilicals
- riser buoyancy
