External Environment
We provide solutions for handling acute pollution, including oil and fuel, in water or on land.
Our expertise lies in managing small and medium-sized installations along watercourses, such as those related to transport, construction and power production.
Our expertise
Management of acute pollution
We deliver all types of solutions for handling acute pollution from oil, fuel, etc. to water or ground. We have extensive experience and solid expertise in handling small and medium-sized installations along water and watercourses. For example in connection with transport, construction work and power production.
When handling acute pollution, great demands are placed on the right competence, as wells as the right equipment. We have precisely this competence and can, in the event of an unwanted incident, contribute everything from task management to government contact and delivery of equipment.
Emergency equipment
We supply oil booms, oil absorbers, absorbent booms, absorbents and related equipment.
Note in particular our "incident kits". These are emergency boxes that are delivered with the capacity to handle smaller spills from 30 to 750 liters. For the power industry, we have delivered a number of these kits that are used in emergency vehicles, workshops, hatcheries and inside the power station itself.
Product overview
Cast Iron Ballast
Ovun Cast Iron Ballast is designed to add weight to subsea cables as well as protect from abrasion and damage due to impact from dropped objects, rock dumping etc.
The ballast system stabilizes a cable laying on the seabed, while also working s as a bending restrictor.
Drill Riser Shims & Riser Protection
Ovun offers excellent solutions for protecting Drill Risers during use and storage.
Our Riser Clamp- and Riser Flange Protection makes it possible for the client to carry out fast and safe deployment and recovery of Drill Risers without Riser Buoyancy Elements.
Bend Restrictors
Ovun Bend Restrictors are designed to prevent cables, flexible pipelines, or umbilicals from overbending and buckling at the interface with a rigid structure.
The Bend Restrictor elements consists of 2 half shells made from a high durability rigid polyurethane, assembled with bolts and lock nuts.
We have developed standard Bend Restrictors for a wide range of common diameters, loads and MRBs. Custom designs with a wide range of features are provided to specific applications when required by clients.
Dilt Floats
Ovun has since the 1990´s developed and delivered Dilt Floats to most seismic companies worldwide.
We have a wide range of Dilt Floats systems that fit most applications.
Our range spans sizes from 270 to 2500 litres, and we can supply floats with plastic or steel fins.
Activa SmartTop Buoys
The Activa SmartTop aquaculture buoy is a long sought after addition to our product line.
With its new and improved fitting, corrosion has been eliminated & the buoy’s weight significantly reduced. With major focus on safety and a life expectancy of 20 years we would like to call this the aquaculture buoy of the future!
The Activa SmartTop buoy has been approved by DNV and constructed and manufactured in accordance with NORSOK R002 with the option to be certified as a lifting appliance if required.
The fitting consists of top and bottom systems made from polyurethane and fiber rope.
The Activa Smart Top series of buoys consist of 9 different models and sizes.
Activa Aquaculture Buoys
Activa is our complete product range of buoys and equipment specially designed for aquaculture and fish farming.
In the development of the Activa series, we have built on our expertise and long experience with production of buoyancy to the offshore industry worldwide. A lot of the learning we have obtained from some of the world’s roughest seas.
Active aquaculture buoys are a complete range from 800 to 12,000 liters. The buoys have an outer shell of impact-resistant, rotational molded polyethylene (PE). The buoys are filled with expanded polystyrene foam (EPS) and has excellent flotation qualities that have been tested and developed over many years. All buoys have through-chain fittings.
Activa buoys can be returned to us for recycling!
Pipe Stacking Units
For safe storage of drilling riser buoyancy on deck, PartnerPlast has developed stacking devices to minimize skidding and increase safety on board. We supply two types – one for the first (deck) layer and one for the following layers.
The products can be delivered for several dimensions of drill risers. The block has fixing points for connecting of wire or strap in order to fasten a sling to the steel pipe of the riser module if desired. The modules are of low weight for easy handling.
Tie in Buoyancy
This product is perfectly designed for buoyancy support of pipeline deployment. Either the buoyancy units can be customer specifically designed to fit a pipe diameter, or a universal design can be used. In addition, adaptors can be supplied to existing units for fitting several diameters.
Modular Support Buoy 234 – Heavy Duty
The MSB 234 series can also be delivered with a Heavy Duty shell as an option, resulting in mooring buoys that can survive even more harsh environments and rough handling.
Modular Support Buoy 180
The MSB 180 series is a mid-size buoy based on the same modularity principle as MSB 234, but with smaller dimensions. Available in all depth ratings from surface to 2500 meters. For surface buoys, AIS, radar reflector and light system can be provided as an option, with a detection range of four nautical miles. The steel work has a MBL of 85t.
