MODULIFT CASE STUDY
UK below-the-hook lifting equipment manufacturer Modulift and its in- house engineering team designed and manufactured a bespoke lifting beam that was capable of recovering a micro tunnelling machine from the depths of the sea earlier in the year. The 50t custom beam had to be designed
for use above and below the water, taking of gravity location and weight of the micro tunnelling machine due to the buoyancy force. Modulift’s in-house team achieved the correct tilt and balance to ensure a At the request of the customer, a specialist in tunnelling and micro- tunnelling, Modulift engaged DNV to perform a third-party design review and certify the beam in compliance with DNV- ST-N001. The design was successfully enabling Modulift to complete the project within eight weeks, from design and drawings, to fabrication, painting, and procurement of rigging. The company engineered the lifting beam with eight lifting points, together
“designed according to the latest energy efficient technology on variable frequency drives for crane applications”. With this type of crane, Havfram Wind can perform operations on the vessel itself, as well as offboard operations, such as lifts to the turbine foundations, to supply vessels, or to the quayside when in port. Havfram Wind has ordered the auxiliary
cranes packages in addition to the 3,000- plus mt main leg encircling crane orders that the company recently awarded to Huisman. With these packages, Huisman has six cranes on order to be delivered for Havfram Wind vessels. The cranes will be produced at Huisman’s production facility in Zhangzhou, China. Cees van Veluw, product director
cranes, Huisman, says: “We are highly appreciative of the trust that CIMC Raffles and Havfram Wind have put in Huisman for selecting us as the manufacturer of the auxiliary cranes for their innovative newbuild jack-up vessels. With these auxiliary cranes included in the package, we can further integrate our lifetime service offering to these vessels, thus improving their efficiency and effectiveness.”
with turnbuckles to connect the lifting beam to the tunnelling machine. The 6.7m-long beam featured two top lugs and four bottom lugs, and tugger points were installed for manoeuvring the beam
REPLACE AND MANAGE Sparrows Group, the engineering and maintenance services specialist for the global energy and industrial sectors recently rebranded as Altrad Sparrows after a 2022 takeover, has been awarded a major crane replacement contract for a client in the Middle East. The project, which is worth $13m, is expected to last 18 months. The scope of work will see Sparrows complete all aspects of the engineering required to replace four BOS (board offshore) Liebherr cranes of four offshore platforms, which are beyond their expected operational life. Sparrows will handle all crane interfaces, installation, commissioning and testing, as well as engineered lift plans for the removal and installation of the cranes using a lift barge, which is to be supplied by the main contractor, along with the new cranes. The project will be carried out in two phases, with phase one taking place onshore from the company’s Abu Dhabi facility and workshop and phase two offshore. Charlie Topp, regional director – Middle
East, India, Caspian and Asia-Pacific at Sparrows, says: “This is a significant contract win for us. We’ve got an extensive

track record in the Middle East, and this contract reflects the confidence of operators and contractors in the region to utilise our expertise as part of safety- critical work. As cranes age, it’s vital that maintenance is done to prolong their life, but in instances like this, where ongoing and frequent maintenance is impacting operations, it’s crucial that new infrastructure is deployed.” While Sparrows will undertake the
majority of the scope of work, it has employed a trusted and local partner to undertake structural fabrication, electrical work, public address and general alarm systems, fire and gas systems and telecoms, as part of the full scope of work. The company has also secured a
contract worth approximately £50m with a major UK Continental Shelf operator to provide crane management services across its operating assets in the North Sea. The five-year agreement, which also
has two, two-year extension options, will see Sparrows deliver crane operations and maintenance services across ten of the operator’s assets in the region. Sparrows has held the contract since 2018 and will continue with the provision of
