APPLICATION REPORT | OFFSHORE
PALFINGER At the WindEnergy show in Hamburg, Germany, in September 2022, and in response to the latest safety requirements of the global offshore wind industry, Palfinger launched a redesign of its well-proven fixed-boom crane range. The PF120-4 is for installation on the transition platforms of the towers themselves, for lifting operations during regular maintenance of offshore wind turbines. The redesigned crane can lift materials
and tools from the crew transfer vessel (CTV) onto the transition piece (TP) platform of the wind turbines and is intended for use during routine inspection and service work throughout the turbines’ entire operational life. The new range has been designed
in accordance with the latest technical requirements of the European standard EN13852-3 for light offshore cranes and plays an important role in lifting spare parts and equipment in the daily offshore wind industry supply chain. “Because access to offshore wind
farms is limited and every working hour must be efficiently used, we’ve made the new PF cranes highly resistant to the harsh environmental conditions,” says
R Palfinger will deliver 60 of its PF120-4 fixed boom cranes to a wind farm in Scotland.
Franz Schnöll, head of global marine product management. “Furthermore, we have reduced the
maintenance effort, to lower the life cycle costs for the wind park owner. The new crane design comes from more than 15 years of installed base experience and
LANKHORST FIRST FOR DEEPWATER SPLICING
Floating wind farms need to be anchored, and generally in deep water. Long ropes Splicing such ropes is not simple. Until now there has been no DNV- deployment and recovery systems, rope systems, ropemakers Lankhorst development of a DNV Endorsement of for its LankoDeep rope. In the event the an end-to-end splice can be made quickly, uninterrupted, without the need for shore- based interventions. The splicing procedure was developed in- deepwater deployment and recovery projects. Designed from the outset for deepwater
lowering and recovery projects, LankoDeep ropes. Ropes are claimed to be easier to handle and allow engineers to lift and deploy the maximum load without the need to factor in the self-weight of steel wire. “Neutrally buoyant LankoDeep allows operators to maximise the lifting capacity of their crane during deepwater deployment and recovery. With the introduction of we’re considerably increasing the utility of LankoDeep, ensuring operations run smoothly,” says Sergio Leite, sales director,
feedback from service teams and our clients. It is therefore well positioned for the future requirements of the global offshore wind industry.”
The design is modular, and standardised
reaches are from 3m to 7m. Safe working loads are 1,000kg at 3m to 7m in single- line operation and up to 3,000kg at 2.9m to 6.9m outreach in double-line operation. Each crane undergoes thorough function and load tests at the assembly plant before being delivered. The procedure is said to ensure ‘plug and play delivery’ with the highest safety standard and minimised installation time. So far, more than 250 of the new Palfinger fixed boom cranes have been ordered and are scheduled to be delivered to the UK, Taiwan, US and Japan between Q4 2022 and Q2 2024. They will be installed on jacket and monopile bottom fixed structures as well as on substations. One such order is for 60 units for
the Moray West Offshore Wind Farm in the outer Moray Firth off Inverness in Scotland, UK. Palfinger is also delivering a PTM1200 jetty crane to the farm’s operations and maintenance base at Buckie Harbour. The large-scale project is being developed by Ocean Winds, a 50-50 joint venture formed by EDP Renewables and Engie. Each of the 60 wind turbines has a generating capacity of 14.7MW. Once operational, the Scottish wind farm is expected to meet the power requirements of about 650,000 households in Scotland for the next 25 years. ●
