HAMPIOJAN -a worldwide network

COMPANY PROFILE In the spring of 1934, midst in the Great Depression, 13 individuals gathered a small fortune to start up an industrial company to manufacture fishing nets, ropes and fishing long lines for the Icelandic fishing fleet. Hampidjan has since evolved to become one of the largest fishing gear and high tech ropes manufacturer of the world, having 14 entities in 4 continents with over 500 employees. We have made relentless product development the essence of our being. We do that so our customers know that if they are with Hampidjan, using advanced DynIce and DynIce Dux ultra high...

Seismic Product Catalogue 1.1. DynIce Towing Ropes. The first DynIce Superwides were taken into use in 1993 as the first ones to replace steel wire on seismic vessels. Since then they have been preferred choice of the seismic companies. The DynIce rope has less density than water and is therefore floating and the lightness makes handling easy. One of the main advantages is excellent abrasion resistance as the rope is constructed with double strands in 12 strand braid configuration. Partly coverbraided Fully coverbraided In 2012 we installed the world largest braider for 12 strand ropes with...

The newest patent pending generation of wide tow ropes combines the best and most advanced materials available today from Dyneema®. The onboard sheave section and the outer end is made of DynIce Ultrabend based on Dyneema® XBO. The main length in-between is then made of DynIce 75 or DynIce 78. The outer end is tapered to double thickness next to the deflector to tolerate better cutting and bending fatigue which can appear in that part. The wide tow rope is however seamless as the material and construction changes gradually in the rope and there are no visible joints. TOTAL LENGTH TOTAL...

Dynlce Seismic Towing Ropes. The Dynlce towing ropes for seismic are cold stretched prior to coverbraiding in order to remove constructional elongation and compact the ropes. This is especially important for coverbraided ropes as if the rope is not fully compacted the cover can slide on the rope. The ropes are impregnated with Duracoat but the cover is without heavy impregnation to preserve the slippery surface of Dyneema. Testing of the ropes is made in state of the art in-house testing bench and tests are witnessed and approved by DNV if requested. Dynlce Towing Ropes Diameter The...

Seismic Product Catalogue 2.1. Fairings. Fairing on towing ropes is important to reduce or eliminate turbulence behind the rope which is vibrations in the ropes. Fairing of the rope which is underwater is made by pulling out part of the cover strands. They can be taken out to different lengths and on one side or both sides of the rope. The fairing strands are specially impregnated in order to extend the lifetime of them. The hairy fairing is made from Dyneema® as it outperforms all other synthetic materials in bending fatigue. The fairing configuration is made according to customers request...

Flexible DynIce Webbing flag fairing for superwides, separation ropes and deflector straps DynIce Swallow tail fairing is alternative fairing type to the conventional hairy fairing and the rigid plastic wings. The flag fairing is made from Dyneema® webbing and is fully flexible and can tolerate the pressure when wound on drums under load. The swallow tail fairing is patent pending. The aim of the invention it to improve the lifetime and effectiveness of the fairing as hairy faring tends to wear out fast leaving the rope without the needed damping to minimize noise and drag. The end of the...

The accurate distance between the streamers is of high importance and not least how the set length will keep for the lifetime of the separation rope. The accurate distance between the streamers is of high importance and not least how the set length will keep for the lifetime of the separation rope. DynIce Dux is free of constructional elongation and will show limited change from initial setup until it is taken off and replaced. For the main rope its possible to choose between DynIce Dux, DynIce 75 and 78. DynIce Dux recommended as its free of constructional elongation and will show limited...

High precision deflector straps for accurate setting of deflector angle. The DynIce Deflector Straps are unique as they have very small tolerances or only +/- 10 mm in lengths up to 10 meters. Moreover they keep within the tolerances throughout the lifetime and maintain the strength as well. In this way they have proven to be unmatchable by other types of straps and are now the preferred choice of the major seismic companies. The DynIce deflector straps are coverbraided with Dyneema® and with heavy and durable eye protection The length accuracy is the key factor to set the exact angle of...

4.1. DynIce Deck Ropes. High performance ropes for various applications were high strength and durability is needed. DynIce 75 Diameter DynIce 75 is reliable and proven 12 strand braided rope from Dyneema SK75 fibres impregnated with Duracoat for improved abrasion resistance. The ropes are soft and flexible and easy to splice. Elongation at break is about 3,5%. DynIce 78 is constructed as double strand DynIce but with the more advanced fiber SK78. All propertis are the same but under high static tension the rist of creep is much less. DynIce Dux is very firm, heatset and stretched 12 strand...

Seismic Product Catalogue 4.4. DynIce 3–eye splice. The 3-eye splice The 3-eye splice connects the lever arm and spurline to the wide tow rope. All eyes are soft eyes with heavy and durable eye protection and hairy fairing to reduce drag and noise. Our experienced team of professional splicers are capable of splicing all kind of braided ropes with the most advanced splice types specially adapted to seismic ropes.
