Invented and manufactured APPLICATIONS by DSM Dyneema. It is a HMPE (High Modulus PolyEthylene) fibre made from UHMWPE Mooring (Ultra High Molecular Weight PolyEthylene). Today’s largest ships, such as LNG carriers, oil The extreme strength of the fibre is due to a tankers, bulk carriers and container carriers, need unique gel spinning process, also developed by mooring lines with a very high breaking load. DSM Dyneema. Traditional steel wire mooring lines are too heavy and difficult to handle with these larger ships, and The result is a fibre which is 15 times stronger even conventional synthetic mooring lines made than steel on a weight-for-weight basis. Besides from nylon and polyester are bulky and heavy. having the best strength to weight ratio, Dyneema® Mooring lines made with Dyneema® are the proven, offers dynamic properties and is highly resistant workable solution. They are much lighter and easier to abrasion, bending fatigue, and environmental to work with than other types. They are as strong as influences such as UV radiation and salt water. steel wire lines of the same diameter, yet less than one-seventh of the weight.

  • Braided Polypropylene Rope
    er Product fold DEAR USER OF THE “PIIPPO PRODUCT FOLDER” This product folder is intended to provide answers to your questions regarding the use and applicability of ropes and twines. More information is available from us by telephone +358 13 562 555 and on our Web site: http://www.piippo.fi There are very few products in the world that are equally old and necessary as ropes and twines. The manufacture of rope is one of the oldest skills of hu- mankind. Thousands of years ago ropes were made of animal hairs and plant roots. Later on, long-fibre products separately cultivated for the purpose, such as hemp, flax, sisal and abaca replaced these ancient rope fibres. The manufacture of rope was important in the early days of industrialisation, and ropemakers could be found almost everywhere. Many famous places have indeed been named after ropes, with Reeperbahn in Hamburg possibly the best known. La Canebière, the main street of Marseille, means ‘hemp street’ and refers to the raw material used for ropes. Turku, the traditional stronghold of Finnish ropemaking, also has a street called Köydenpunojankatu (Ropemaker Street). There was a factory along that street with a rope line producing ropes directly in 220-metre lengths. Piippo Oy was established in 1942, in the midst of national hardship. At that time, the company’s founder Matti Piippo invented and patented a method for manufacturing paper twine. Today, Piippo Oy is headquartered in Outokumpu. During the years, Piippo Oy has grown into one of the most important manufac- turers of ropes, twines and nets in Northern Europe.

  • Design and Application of Buoy Single Point Mooring System with Electro-Optical-Mechanical (EOM) Cable
    Journal of Marine Science and Engineering Article Design and Application of Buoy Single Point Mooring System with Electro-Optical-Mechanical (EOM) Cable Junwei Yu 1,2,*, Shaowei Zhang 1,*, Wencai Yang 1, Yongzhi Xin 1 and Huaining Gao 1 1 Institute of Deep-Sea Science and Engineering Chinese Academy of Sciences, Hainan 572000, China; [email protected] (W.Y.); [email protected] (Y.X.); [email protected] (H.G.) 2 College of Materials Science and Opto-Electronic Technology, University of Chinese Academy of Sciences, Beijing 100049, China * Correspondence: [email protected] (J.Y.); [email protected] or [email protected] (S.Z.) Received: 17 July 2020; Accepted: 27 August 2020; Published: 1 September 2020 Abstract: This paper presents the design of a hybrid system named the Mooring Buoys Observation System for Benthic with Electro Optical Mechanical Cable (MBOSBC) for long-term mooring buoy observation in deep oceans. MBOSBC is comprised of three main modules: a surface buoy, a benthic node, and an Electro-Optical-Mechanical (EOM) cable. The Surface buoy provides energy for the entire system, the Benthic node is used to observe scientific phenomena on the seabed, and the Electro-Optical-Mechanical (EOM) cable connects the sea surface buoy and the benthic observation node, serving as the information and power transmission link. This paper provides design criteria for a single point mooring buoy using an EOM cable. The environmental load of the buoy under varying wind, wave, and current conditions is analyzed and the mooring hydrodynamic force of EOM is calculated. After calculating the load of the EOM cable under extreme marine conditions, the hydrodynamic force needed for the system is analyzed.
