Cargotec’s subsidiary MacGregor has actually won an agreement with the united state overseas assistance vessel proprietor Otto Candies to provide an energetic heave made up FibreTrac offshore crane.
The order was scheduled in Cargotec’s 2022 very first quarter order consumption, with distribution anticipated to be finished by the end of the year. MacGregor informed Offshore Engineer that the crane would certainly be mounted aboard the Wyatt Candies dive assistance vessel.
The range of supply consists of complete distribution of the 150t AHC crane, ranked for the customer’s requirements at 100t training ability, along with Lankhorst Lanko ®Deep Dyneema DM20 fiber rope for 3400m functional deepness.
“The crane is the first of its type and provides the ability to lift heavy loads at depths that normally require much larger cranes on larger vessels,” MacGregor stated.
“This highly innovative crane uses neutrally buoyant fiber rope with an Applied Fiber termination connecting directly to the hook allowing full payload at all depths. This is in contrast to standard wire-rope cranes, where the weight of the steel wire steadily robs the crane of its lifting capacity as more wire is paid out,” the firm stated.

According to MacGregor, the FibreTrac principle was established in cooperation with Parkburn Precision Handling Systems, which will certainly provide the fiber rope Deepwater Capstan (DWC) that delicately de-tensions the rope in between the high-tension functional side and also the low-tension storage space side.
Parkburn likewise established the crane’s Lift Line Management System which handles rope health and wellness tracking and also comments making use of a mix of noticing modern technologies and also a life time use formula established by DSM based upon their DM20 product.
According to MacGregor, the subsea AHC fibre-rope crane will certainly have the globe’s very first DNV-DRS course symbols based upon the DNV-ST-E407 requirement.
“This new standard governs how such a crane and its rope system can remain continually certified based on real-time measurements of rope health and represents a significant departure from earlier certifications based on prescriptive rules and periodic inspections,” the firm described.
“Owners and operators can now have an up-to-date health status of every portion of the lift-line and use it confidently and to its fullest potential, instead of guessing based on work hours since the last inspection and cutting back or replacing it,” MacGregor stated.
“The drive for much better vessel application and also effectiveness has actually never ever been more powerful in the overseas globe. Thanks to all that have actually added to creating this one-of-a-kind crane which we are really pleased to get involved in procedure,” states Jan Erik Pedersen, Senior Vice President, Offshore Solutions Division, MacGregor.
