Coltraco manufacture Ultrasonics That Work

The difficulty of fire in wind turbines:

  • Potential ignition sources are mainly inside the nacelle where there is fast moving machinery (generators, gearboxes e.t.c) which creates heat and combustible oil and solid material in the. Even with the incredible engineering and safety measures in place, a fire can ignite and develop, leading to the possible complete destruction of the turbine.
  • It is estimated that 0.3-0.5 fire incidents occur per 1000 wind power stations (onshore and offshore) every year (Technical Research Institute of Sweden). 10-30% of all loss-of-power-generation incidents in wind power plants are due to fire.
  • Gaseous Extinguishing Systems in turbines:
  • Wind turbines require an active fire protection system, which includes but is not limited to detection (of flames, heat, gas, and smoke), alerting personnel and rescue services, and activating systems for fire suppression or extinguishing. Due to the height and location of wind turbines, classic firefighting methods come up against their limits and therefore fire extinguishing systems that use gases such as carbon dioxide, inert gases or clean agents such as FM 200 fire suppression system and Novec™1230, which are especially appropriate for dealing with fires in electrical systems because they extinguish the fire quickly whilst not damaging the electrical systems or the compartment in which they are being discharged.
  • Regulations demand maintenance of the systems to ensure that they are operational in the event of a fire: ISO 14520-1:2015(E) assumes that these systems accidentally discharge and leak. 9.2.1.3 The storage container contents shall be checked at least every six months as follows. a) Liquefied gases: for halocarbon agents, if a container shows a loss of agent in quantity of more than 5 % or a loss of pressure (adjusted for temperature) of more than 10 %, it shall be refilled or replaced.”
  • The reality is that gaseous systems are checked for contents annually because they are pressurised and anything that is dynamic offers risk of loss of contents, but this fails to deal with the probability of discharge or leakage for the 364 days per annum in the interim between certification checks.
  • Coltraco have now developed the Permalevel® Multiplex, a fixed fire suppression monitoring system, designed for continuous contents verification. Permalevel® is designed to ensure that fire suppression systems are always fully operational and that no accidental discharge has occurred, which could affect the effectiveness of the overall fire protection system in the event of a fire.

 

CEO Message

Integrity and Science Key to Our Culture of Performance

Dear Coltraco Customers, Strategic Partners and Distributors,

Integrity is our defining value. Performance is its consequence. We understand that our customers have choices, and how we perform determines whether customers choose us. Coltraco’s Code of Ethics does not merely require compliance with laws. It embodies a Commitment to positive behaviours that build trust, promote respect, operate with distinction, with courtesy and global levels of performance, demonstrating our integrity and delivering customer performance.

We honour our commitments, communicate transparently, and act with honour. Ethics are the foundation of our performance culture and our science-based approach. We lead in specific technologies delivering the watertight integrity monitoring of marine structures and the monitoring of fixed liquefied gaseous fire extinguishing systems and the room integrity of protected space to ensure agent hold-times post-installation. We show this by our understanding of the science in them and the mathematics that explain them.

I would like to thank you for your business and for the relationships with our Customers, Strategic Partners, Distributors and ODAs who we value so highly.

My kindest regards,
Carl
