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 |
 |
The soft eyes of the ropes at the end can also be provided with reusable monel bollard K - 400 grade and Bell mouth thimbles IS 2062 grade |
 |
The Thimbles and Monel blocks are ultrasonically tested. The Thimbles are Hot dip Galvanized to suit marine conditions. |
 |
Rope legs inside the Bell Mouth Thimble will be covered with Polyurethane coated Polyester fabric for chafe protection. |
 |
In case of Cast steel thimble, PU encapsulation shall be provided inside the thimble to prevent chafing. |
 |
Additional optional protection such as PU cloth protection / Leather covering / Rubber sleeve can be provided as per customer’s desire |
 |
Lace on type pocket hawser floats will be provided over the length of the Hawser at regular intervals so as to have at least 20 % reserve buoyancy to support the rope in sea. |
 |
For double leg systems a double collar float will be provided over the Spliced portion of the rope. |
