Major improvements achieved over 50 years of service
Since its creation, the Research and Development department has focused on continuous innovation. Discover the dates and key turning points which have enabled us to improve the performance and durability of LE DREZEN fishing gear.
- 1960 : 1st tuna seine net manufactured in Europe for the Atlantic. Development of assembling technique mesh by mesh.
- 1980s : introduction of openable rings facilitating manoeuvres at sea
- 1981 : Acquisition of an autoclave for dimensional stabilisation of the netting. Service life increased by 20%.
- 1988 : Introduction of FNI (Fishing Net Impregnation) for better UV and abrasion resistance and the acquisition of an industrial drying oven for optimised treatment.
- 1989 : Black nylon dyed in mass (durability 2.5 times longer than with ecru nylon dyed black).
- Beginning of 1990s : Introduction of EVA (ethylene vinyl acetate) floats to reduce maintenance costs.
- 1997 : Creation of a unique digital simulation programme for tuna fishing to optimise the design of our seine nets and to help choose the appropriate mechanical materials.
- 2004 : Reinforcement of high and low ropes for improved durability.
- 2012 : Sustainable development programme for the treatment of our seine nets.
- 2013 : 20% increase of the service life of nets by improving their mechanical properties. Creation of a specifications document for the adjustment of all components in order to prolong their service life (90% of WireCo World Group products).
- 2016 : With the support of WIRECOWORLDGROUP, LE DREZEN is now the only Western industrial group to design and manufacture complete tuna seine nets. The R&D department believes it can prolong the service life of a seine net by another 30%.
Innovation over the next 3 years
Every piece of information is exploited : the power of the vessel and the progression of propulsion systems, ocean currents, weather conditions in the fishing zone, fishing companies’ specific expectations and the bosuns’ and crews’ know-how.
All of this data is analysed then reproduced by a unique digital simulation programme, which LE DREZEN will continue to invest in over the next 3 years.
The direct result of this innovation is the reduction of damage and operating loss and reducing maintenance costs for the fleet owner. This cost optimisation goes hand in hand with our sustainable and responsible fishing policy.
