Go deeper with Diab buoyancy foams

High-performance materials

– Crucial for these demanding applications Diab materials provide excellent buoyancy, strength and insulation for a smooth and sustained operation

Buoyancy

– Diab’s wide range of low density foams can withstand water pressure from sea level down to 10 000 meters

Low water absorption and improved impact protection

– Buoyancy foam surfaces can either be treated with laminate, paint of your choice, left as-is, coated or included in a sandwich construction depending on the application need


Excellent strategic partner

– Diab has been providing solutions for subsea applications for more than 40 years. We have the knowledge and skill to help you realize your product needs

Long service life and low maintenance

– This is what makes Diab's buoyancy foams a cost effective material bringing optimal life cycle economy to your project

Understanding buoyancy requirements

Pressure is applied from all directions in subsea environment

Polymer materials will loose buoyancy over time due to creep behavior and water absorption

HCP stands for Hydraulic Crush Point and is defined as the point of pressure in Bar, where the material when subjected to an increasing pressure of 1-2 Bar/second has lost 5% of its initial volume.

(Hydrostatic Crush Point - QII 111-1, internal Diab standard)

Hold your breath for this

BACKGROUNDDWTEK is Taiwan’s first marine inspection equipment manufacturer and supplier. To develop their flagship ROV, the Investigator, they needed technical expertise and support and the right materials.

SOLUTIONDWTEK have been partner with Diab for more than 5 years and it was natural for them to seek advice at Diab.

RESULTDiab supplied Divinycell HCP for the construction of the Investigator. The vessel has outstanding payload capacity and works according to all requirements.

SUCCESS FACTORS:Diab’s Divinycell HCP offers low water absorption and low buoyancy loss up to 700 meters depth, making it the ideal material for the Investigator.

Plumbing new depths

BACKGROUNDArgus designs and manufactures its own range of remotely operated vehicles (ROVs) for subsea missions like surveys, repairs, maintenance, laying cables and pollution control.

SOLUTIONBoth Divinycell HCP and Syntactic Foams are used in Argus ROVs. Divinycell HCP offers very low buoyancy loss and water absorption under long-term loading conditions. BTMI Syntactic Foams offer very high buoyancy per kilo.

RESULTCurrently Argus offers ROVs with depth ratings to a maximum 6,000 meters (19,685 ft.). Although the company has five models in its current line-up, each ROV can be individually customized with a variety of add-on modules to suit customers' needs.

Diving into the sea

BACKGROUNDThyssenKrupp Marine systems has from proven design principles of previous submarines in the family now developed the HDW Class 214 submarine.The new submarine is well equipped to perform various missions, ranging from operations in littoral waters to ocean-going patrols.

SOLUTIONThe HDW Class 214 design is characterized by the following features:

• increased underwater endurance• increased diving depth

RESULTThanks to its modular design and high degree of automation, this submarine is a very cost-effective weapon system, extremely difficult to detect and thus the unbeatable solution for future-orientated navies.

With the power of the tide

BACKGROUNDIrish-based OpenHydro specializes in the design, manufacture, installation and maintenance of marine turbines for generating renewable energy from tidal streams. The company’s vision is to deploy arrays of tidal turbines under the world’s oceans, silently and invisibly generating electricity at no cost to the environment.

SOLUTIONSimplicity of design is at the core of OpenHydro’s turbine technology. It features a horizontal axis rotor with power off-take through a direct drive, permanent magnet generator.

The design has no need for a gearbox or other complicated components requiring regular intervention, and is based on a philosophy of zero maintenance between overhauls. The turbine is manufactured from a combination of glass reinforced composite materials, steel and Diab structural cores.

RESULTFrom an environmental standpoint, the OpenHydro design minimizes the risk to all forms of marine life in several ways. Firstly, the rotor blades are retained within the outer housing and secondly a large center provides an exit route for marine life. In addition there is no requirement for potentially toxic oils or lubricants.

Last year, OpenHydro successfully deployed the first commercial scale in-stream tidal turbine in the Bay of Fundy, Canada, on behalf of its customer, Nova Scotia Power.

Tough, even below the surface

BACKGROUNDOffshore oil production needs reliable protection for sensitive pipelines and production valves from damage in their installed position subsea. Threats to these subsea installations are defined as loads from dropped drill strings and fishing equipment like trawl boards.

SOLUTIONCSUB produce protection covers designed according to DNV-OS-C501 Composites Components and NORSOK U-001 Subsea Production Systems. CSUBs covers prevent structural damage by providing excellent impact protection with the help of Diab’s high strength core material, hatches are made easy to operate by ROVs. Diab’s HCP keeps it original volume over a long period of time and unlike other types of material does not crack upon impact.

RESULTDue to its excellent strength to weight ratio and the long service time subsea, Diab’s HCP material has allowed CSUB to create excellent and vital protection to subsea pipelines and other subsea structures in need of protection on the sea bottom.
