Ramnas provides offshore safety in your mooring system through high quality anchor chains and acc.

Ramnäs Bruk will give you best quality through the entire purchasing, fabrication and supplying phase of your offshore project. Ramnäs Bruk, Sweden, is a leading manufacturer of quality chains. Alone in the market with 5 year quality warranty for all chain! Ramnäs staff knows how important the chain is for their customers. Quality is a way of the everyday life at Ramnäs Bruk! Fourty-five years of experience working in the offshore sector and producing chains since 1876 in Ramnäs, Sweden. Twenty-five years without a single customer claim due to fabrication failure. Ramnäs quality chain begin in the steelworks that manufacture and supply the high-grade steel that is required. Based on decades of experiences and constant technology development Ramnäs Bruk has a wide and deep knowledge of the alloys and characteristics developed for all our chains including the new grade 5 chains. Ramnäs Bruk has a long experience from offshore mooring chain production and combined with state of the art techniques, a service for inspection and storage of chain and accessories can be provided. Ramnäs Bruk is a world-wide class manufacturer of high-quality offshore chain meeting the classification societies highest quality standards. The best stud link anchor chain on the market is produced in Ramnäs! Ramnäs stud link chain is superior compared to all other available stud link anchor chain, this is due to Ramnäs unique manufacturing method of controlled stud expansion. Our manufacturing process conforms to the international quality assurance standard ISO 9001:2008. The first forging-hammer was built by the Queen dowager Catarina Stenbock, to whom the whole district belonged as fief. Swedish wrought-iron played an important role in Swedish export the following three-hundred years. During the second half of the nineteenth century the wrought-iron manufacture in Ramnäs was completed with a rolling mill, thus creating a fully integrated manufacture of steel bars from pig iron. Ramnäs Bruk has through the years been a pioneer in the development of chain and connector design as well as in the introduction of new manufacturing, inspection and testing routines. New connector designs, latest version known as RF-connector, were introduced in 1990 and a new stud chain design, with an asymmetric stud in combination with controlled stud expansion, was introduced in The greatest step seriously affecting the development of anchor chain came during the sixties when the offshore industry started to utilise ships-chain for mooring of drill-ships and semi-submersible platforms. Offshore chain is continuously subject to load, whereas the chain on most ships is in rather infrequent use. Thus the offshore chain has to withstand considerably more severe conditions than ships-chain, particularly as regards resistance against fatigue. The traditional chain for ships was always tested and delivered in 15 fathoms-lengths which were shackled together to longer lengths. The offshore industry wanted continuous lengths without shackles and our new factory responded to the customers’ wishes. In this new factory we also developed the continuous test-loading of the chain, breaking the very old tradition of testing 15 fathom lengths. Too much chain was produced without waiting for the practical consequences in offshore operation. The following decade was devoted to fine tuning of specifications as well as of works practice and of material qualities utilised for grade 2003 Delivery of chain with extra high demands in taylor made length was performed.
