The Salient features of our SPM Hawsers:
The SPM hawser will be a Single / Double Leg Grommet type assembly made of Nylon / Maxiflex (up to 120 mm dia.) 8 strand Braided rope.
PE braided netting with copper and steel wire to reduce algae growth and protection from predators
The Length of the Hawser assembly will be maintained as required.
The ropes will be manufactured, inspected and tested in accordance with OCIMF guidelines 2000 - First edition.
The New Dry Breaking Strength of the rope would be verified by Third Party Surveyor i.e. Lloyd’s Register Asia.
For double leg grommet assembly, the calculated assembly strength will be 1.7 times of the New Dry Breaking Strength of the rope.
The TCLL (Thousand Cycle Load Level) value as determined by prototype cyclic load procedure described in OCIMF will be 75.63 % of NWBS (New Wet Breaking Strength) for Maxiflex ropes and 50 % for Nylon ropes.
The material of the rope will be composite fiber i.e. Mix of Polyester and Polypropylene for Maxiflex and 100 % Nylon for Nylon ropes.
For double leg systems the legs will be tied / seized together at minimum 7 places for a ength of 1.2 m each.
For double leg grommet, each leg will have an end for end splice in the center thus balancing the total assembly.
The rope will form soft eyes at each end. The ends will have a polyurethane encapsulated Cast Steel Thimble IS 1030 : 1998 Gr. 230 – 450 W grade

•  Verification of auxiliary gear and 20% reserve buoyancy.
•  Verification of thimble material and dimension as per customer approved drawing.
•  Verification of chafe protections as per customer requirement.
The inspection agency / third party will stamp the Thimbles of each rope after inspection.


PACKING

The hawsers will be packed in wooden boxes. The wooden boxes will be lined with PE film. Rope slings will be provided for lifting the box as well as the hawsers from the box. Total product description will be displayed at three sides of the box for customer reference.

Advantages of 8 strand constructions

An 8 strand construction with 4 “s” way laid and 4 “z” way laid strands gives torque free and completely balanced mooring rope.
8 strand is a flexible construction under dry or wet condition. So easy to handle.
Easy to inspect because of braided construction and so regular inspection on site is possible. In case of double braided internal structural damage in the core cannot be checked.
