Moorlink - Wire Clamps, Swivel Links, Connections and Mobile Mooring Components
|
MoorLink's special mooring components meet the most extreme needs of the demanding offshore industry. We design, produce and install certified swivel links, connections and wire clamps for use on any chain, wire or rope. We have numerous by ABS/DnV approved swivel sizes and are involved in functional testing in test beds in co-operation with well-known laboratories. Since 1995, Moorlink has delivered approximately 1,000 units worldwide. We focus on providing products for the following solutions:
Swivel links The ML 1200/40 long term mooring (LTM) swivel link was especially designed for the FPSO "PetroJarl Foinaven", which is moored west of Shetland. The link connects the upper two wire segments (diameter 135mm, six stranded wire each), as well as joining the 40 Te net up-lift subsurface buoy to the mooring line. The swivel link is constructed from a 200mm thick plate and includes a large diameter brass bearing, which prevents the buoy pigtail from twisting around the mooring line. Composite Orkot bushes or washers (in total 14 on each swivel link) protect all items in movement. Extensive technical investigations and calculation were performed in order to ensure these swivel links will withstand the harsh environment for a period of at least 20 years. This included fatigue and static calculations as well as cathodic protection calculations to meet DnV's standard for long-term mooring systems. The complete weight in air is 2,450kg each. Wire clamps The ML 64-90/40 patented wire clamp is a specially designed wire clamp developed to fit surface or sub-surface buoyancy to six stranded mooring wires of any diameter. The clamps are cast in a high-grade steel, heat treated for correct material characteristic and finally machined to fit perfectly. A mould is then taken of the six stranded wire, which is placed in between the two halves of the outer casted casings. A specially chosen type and hardness of polyurethane is then poured into the inside of the steel halves. The result is a high performance system, which serves the two requirements of extremely high longitudinal holding power and minimum wear/fatigue of the mooring wire. The outer part accommodates a swivel with a built-in shackle for easy fit of the buoy pigtail. The swivel limits the torque effect, which is built up in the mooring wire whilst under tension. Moorlink has successfully supplied over 100 clamps in wire sizes from 64mm to 90mm wire rope. Other sizes are also available upon request. Swivels MoorLink swivels are supplied in either forged or cast versions. The structural design is thoroughly analyzed by FEM-analysis and allows the swivel to run through a fairlead, chaser ring or over an anchor handler stern roller under high load, avoiding damage to the bearing system or any other swivel part. The bearing consists of a high grade, maintenance free bronze alloy slide bearing, moving over a polished stainless steel washer. All swivels are approved by the major certifying authorities. Buoyancy support The MoorLink patented wire and chain clamps are specially designed and developed to fit surface or sub-surface buoyancy to mooring wires or chains of any diameter. Our clamps are cast in a high-grade steel, heat treated for correct material characteristic and finally machined to fit perfectly. The result is a high performance system which serves the two requirements of extremely high longitudinal holding power and minimum wear/fatigue of the mooring wire. M-link The polyester mooring line connectors M-Link consists of two main plates and two main tubular shafts, eliminating the need for having loose and expensive thimbles. The holes in the shafts can also be used for simpler handling during installation and recovery. This means no handling shackles are required. By introducing the hollow pin design we have managed to integrate a few advantages which make it a very competitive alternative solution for connecting polyester/composite mooring lines. Tether systems MoorLink is a major supplier of tether systems for suspension of free-standing steel hybrid risers in buoyancy cans. In recently completed projects, we comply with the new extended testing requirements made by operators and classification companies.

  Expand ImageThe ML 1200/40 LTM (Long Term Mooring) Swivel Link was designed and developed for the Golar Nor FPSO Petrojarl Foinaven 10-point mooring system.  Expand ImageThe ML 1200/40 includes a large diameter Johnson Oile brass bearing avoiding buoy pig tail twisting around the mooring line whilst under tension/torque. All steel parts in the movement are protected by Orkot composite bushes and washers to avoid mechanical wear.
