MacGregor's new fibre-rope retrofit option extends subsea crane capabilities
(Thomson Reuters ONE) -
CARGOTEC CORPORATION, PRESS RELEASE, 16 JUNE 2016 AT 11 AM EEST
MacGregor, part of Cargotec, has launched a fibre-rope retrofit option for its
subsea cranes. The modular upgrade replaces the crane's original steel wire rope
with high-performance synthetic fibre rope, using the same technology as
MacGregor's advanced fibre-rope crane, the FibreTrac 1500, which was introduced
earlier this year.
These game-changing cranes combine MacGregor's proven offshore crane technology
with the fibre-rope tensioning technology perfected by Parkburn Precision
Handling Systems.
"We are proud to introduce our fibre-rope retrofit option to the market. This
unique system offers a good investment to our customers to expand their
operational window," says Alexander Nürnberg, Senior Vice President, Technology
and R&D, MacGregor.
Heavier lifts at greater depths
Fibre rope's great advantage when used in this context is that it weighs
virtually nothing in water, so regardless of the length of rope paid out; it
does not add anything to the load experienced by the crane. This is in complete
contrast to wire rope, where the increasing weight of wire paid out
progressively and seriously limits the load permissible in relation to depth.
"MacGregor is always searching for new solutions that deliver a competitive edge
for our customers," says Gaute Sjusdal, Director of Advanced Offshore Solutions,
Global Lifecycle Support at MacGregor. "By employing this fibre-rope technology,
a crane is able to use its full lifting capacity at maximum depths, so a smaller
crane and vessel can be used for more assignments. The fibre rope crane can lift
loads at practically any depth that is required, allowing these vessels to bid
on a wider range of contracts."
Effectively, a 100-tonne fibre-rope crane has the same lifting capacity as:
- a 150-tonne crane with steel wire rope, lifting at a depth of 2,000m
- a 200-tonne crane with steel wire rope, lifting at a depth of 3,000m
- a 250-tonne crane with steel wire rope, lifting at a depth of 3,500m
Quick installations minimise downtime
The retrofit system is designed in modules for rapid installation. It includes a
deep water capstan traction device, delivered in partnership with Parkburn
Precision Handling Systems, which replaces the crane's original main winch and
overcomes the problems traditionally associated with handling fibre rope. The
system also includes a low tension fibre-rope storage drum.
The fibre rope can be inspected for wear, internally and externally. The ability
to splice in new sections adds great flexibility to the system. "While the
entire rope can be replaced if necessary, damaged sections can easily be
replaced and the length can be increased as required," says Mr Sjusdal.
"Transportation is simple and requires no special equipment. In contrast,
3,000m of steel wire rope poses some significant challenges and has special
transportation, handling and spooling requirements. With its low weight, a
synthetic fibre rope can be shipped in a normal container; there is no need for
a drum. Also unlike wire rope, fibre rope does not require lubrication,
eliminating a source of pollution.
"The crane will be continuously connected to a monitoring system, which delivers
real-time data used to detect conditions that could lead to a breakdown. We will
distribute operational parameters to our customers, to ensure that the equipment
works to its best potential," Mr Sjusdal notes. "This is also a good example of
how MacGregor customers can benefit from the broader experience that Cargotec
has across the cargo and load handling industries in leveraging analysis to
develop insights and value from data."
