Advantages of 8-strand rope: + efficient construction + torque-free + easy to handle + easy to splice Points of attention: - yarns can be pulled - in winching: only on a split drum 8-Strand Multiplait Rope Construction Cosalt/Bexco Offshore Mooring Systems for operational performance, reliability, safety & on-time delivery

Advantages : better abrasion resistance; smooth surface (strands/yarns will not get caught easily) rope is round : visual aspect easy to use on the winch (no burying because of round construction) non-rotating endless ropes possible very easy to splice ideal for lifting with free end (non rotating + round) 12-Strand Multiplait Rope Construction Cosalt/Bexco Offshore Mooring Systems for operational performance, reliability, safety & on-time delivery

Ultraline Construction Rope Construction Typical penetration of UV into rope is 1-2 mm cores cover - Cover not only protects against abrasion, but also UV - Small repairs are possible if inner strength has not been ccompromised – strength will not be affected. - All rope strength is contained within central cores.
