application are used.
Using one of the largest closing machines in the world,
Haggie can manufacture anchor lines as large as 150mm
in diameter in continuous lengths up to the equivalent of
120 tonnes per length.
Due to the rough handling anchor lines receive, its is
sometimes considered that a galvanised surface finish is
not warranted. This range of ropes is therefore available
as drawn-galvanised or ungalvanised.

3. Anchor Lines for
Offshore Exploration
All anchor line ropes are manufactured in right regular
lay to limit rope torque in service. Ropes of 103mm (4
in) diameter and less are available in IPS, EIPS and
EEIPS grades. The larger ropes in the 6x55/IWRC
construction are supplied in EIPS grade as a standard.
Higher breaking forces are available subject to negotia-
tions at time of enquiry

gral part of Haggie's offshore capability.

5. Drill Lines
Product description
The string of drill pipes is raised and lowered by means
of the drill line. This operation requires a rope construc-
tion with maximum resistance to abrasion and crushing
on the multi-layered drum.
The recommended rope is a 6x19/IWRC, EIPS grade,
right regular lay, ungalvanised.
The 9 large outer wires provide resistance to abrasion,
while the IWRC enhances crushing resistance as well as
contributes towards the rope breaking force. The right
regular lay reduces the tendency of the rope to build up
torque during the operation.
6x26C/IWRC UHP ropes have proved a major success in
rotary drilling applications.
An 8x19/IWRC rope construction has also been used
successfully for this application by some operators; the 8
strand construction provides superior fatigue life but the
smaller wires may adversely affect abrasion resistance.
