    SIGMA Mooring Tail Rope

  • Description

    The mooring tail rope provides both high strength and flexibility, helping to absorb shock during mooring operations. It connects to the primary mooring line to enhance safety and stability.

Product Connection Regulations LMP


The mooring tailrope is designed to absorb shock during mooring operations, helping to ensuresafe and stable mooring. It is typically connected to the primary mooring line,minimizing the impact from environmental factors such as waves and wind. It canbe easily applied to vessels of various sizes, providing long-lasting, reliableperformance.



Key Features:


  • Compliance with OCIMF regulations
  • Absorbs shock during mooring operations
  • Made from synthetic fibers with excellent durability
  • Resistant to corrosion and chemical damage
  • Suitable for use with various vessel sizes
Product Connection Regulations LMP

Using the cow hitch between a correctly sized single leg tail and mooring line does not significantly affected the strength efficiency of the mooring line assembly. When connecting to a grommet tail the strength reduction can be higher due to the larger influence the D/d ratio has on tail strength. Oversizing of tails to account for the potential loss of strength is not recommended due to the consequent effects on termination integrity and tail stiffness. Cow hitch connections should never be used to connect steel wire mooring lines to synthetic tails.

Product Connection Regulations LMP

-Every vessel shall have Ship Design MBL.

-Every vessel shall implement LineManagement Plan (LMP)


Newregulations and guidelines


The IMO Maritime Safety Committee (MSC) hasissued new requirements related towing and mooring equipment. The requirementsare incorporated in the amendments to SOLAS Regulation II-1/3-8 and will comeinto force on 1 January 2024.


• IMOMSC.1/Circ.1175/Rev.1, “Guidance on shipboard towing and mooring equipment”


This circular has been updated to nowinclude a reference to the calculation of the Ship Design Minimum Breaking Load(SDMBL). The update will apply to all vessels constructed after January 2024.The original document remains in effect for vessels built between January 2007and January 2024, and is not replaced by the revised version.


•IMO MSC.1/Circ.1619, “Guidelines on the design of mooring arrangements and theselection of appropriate mooring equipment and fittings for safe mooring”


These guidelines are applicable to allvessels constructed on or after 1 January 2024 and offer details on the designof mooring systems as well as the selection of mooring equipment, includinglines.


•IMO MSC.1/Circ.1620, “Guidelines for inspection and maintenance of mooringequipment including lines”


These guidelines are applicable to allvessels and provide guidance on the inspection and retirement of mooring lines,along with the criteria for replacing lines after their retirement.

 


Keydefinitions


Ship Design MBL (MBLSD, SDMBL)

Ship Design Minimum Breaking Load. The minimum breaking load of new, dry, mooring lines for which shipboard fittings and supporting hull structures are designed in order to meet mooring restraint requirements.

LDBF

Line Design Break Force. The minimum force that a new, dry, spliced mooring line will break at. (Wet for only nylon) 100-105% of SDMBL

TDBF

Tail Design Break Force. The minimum force that a new, wet, spliced mooring tail will break at. 125-130% of SDMBL

WLL

This is the maximum load that a mooring line should be subjected to in operational service, calculated from the standard environmental criteria.

Steel wire rope : 55% of SDMBL / Synthetic rope: 50% of SDMBL

D/d

The diameter, D, of a mooring fitting divided by the diameter, d, of a mooring line that is led around or through the fitting. The D/d ratio is used by mooring line manufacturers to specify the minimum radius of a fitting around or through which a mooring line of diameter "d" should be led, in order to reduce or mitigate bend loss of strength of the mooring line.
