Vattenfall increases WTG servicing capability
Vattenfall is increasing its offshore turbine servicing capabilities by signing a multi-year framework contract with Van Oord for the charter of its jack-up vessel, MPI Resolution. The contract will provide guaranteed availability of the vessel for several months each year, primarily during the peak maintenance season from early March to late October. With an option to extend beyond the initial term, this partnership is expected to mark a substantial step forward in Vattenfall’s operational efficiency.
“By ensuring the availability of the MPI Resolution, we anticipate significant improvements in our operations and maintenance activities when it comes to main component replacements,” said Pavlo Malyshenko, head of Offshore Generation at Vattenfall.
MPI Resolution will be given the task of servicing Vattenfall turbines of up to 5 MW in capacity across Northern Europe and the UK.

CPH2, the UK-based green hydrogen technology and manufacturing company, that has developed an IP-protected membrane-free electrolyser (‘MFE’), has successfully completed the Factory Acceptance Test (FAT) for its MFE110 electrolyser, marking a major milestone for the company’s technology. This success confirms the first customer acceptance and validation of CPH2’s membrane free technology, proves that it works at scale, and paves the way for a commercial roll out of the MFE220, CPH2’s flagship 1MW system. The FAT was completed after a formal demonstration of the MFE110’s successful operation and performance, independently witnessed by Lagan MEICA the Principal
Contractor, and Arup, representing Northern Ireland Water. The MFE110 has successfully produced separated hydrogen and oxygen at the pre-determined specifications for commercial deployment.
For CPH2 this means it has a viable and potentially competitive alternative to PEM and Alkaline electrolysers. The next stage is the deployment of the MFE 110 unit to Northern Ireland Water’s site for installation leading to commercial hydrogen and oxygen production. The final stage of the MFE110 FAT involved successfully verifying the safe and fully automated startup, operation, performance, and shutdown of the MFE110 unit to the pre-
determined specification. During this operation, key metrics such as the unit’s hydrogen and oxygen output pressure, flow rate, and purity levels were recorded. All metrics achieved the necessary thresholds, confirming that the unit can function effectively. The MFE110 will now be shipped to Northern Ireland Water for site installation, integration, and commissioning, before commencing commercial hydrogen and oxygen production.
CPH2 will now move to the commercialisation phase, which involves delivering on three existing customer contracts for MFE220 units, activating the licensees and supporting them, and continued technology and product improvement.
Safety oriented multimeter
Fluke, a prominent manufacturer of compact, professional electronic test and measurement tools and software, has introduced its Fluke 283 FC Solar Digital Multimeter and the Fluke a283 FC True-RMS Wireless Clamp, designed to enable solar professionals to work more confidently, without compromising safety in high voltage environments such as a testing individual panels, strings or invertors in utility-scale solar photovoltaic arrays.
The 823 FC/PV Solar Kit includes CAT III 1500 V DC safety rated accessories that enable technicians to work confidently in high-voltage environments. With Staubli MC4 test leads, professionals can quickly make secure connections to modules or strings to test DC voltage up to 1500 V DC, well suited to utility operations.
The TL175-HV CAT III 1500 V / CAT IV 1000 V rated silicone test leads offer flexibility for testing voltage, millivoltage, resistance, continuity, and capacitance on inverters, combiner boxes, PV arrays, and individual PV modules.
Fluke says that the key benefits and 40 | November/December 2024|

features include highly accurate and precise voltage measurements for accurate frontline troubleshooting; 60 amp AC/DC current capability for safely troubleshooting individual strings of modules using the a283 FC wireless current clamp; visual and audio polarity indicators to help prevent accidental module wiring issues.
Other features include a user-defined
limit gauge, what it calls a unique multimeter readiness self-check, and a large bright backlit display and illuminated keypad.
The a283 FC True-RMS wireless current clamp is said to simplify the troubleshooting process without compromising safety and reliability. It measures both AC and DC current up to 60 A, ensuring precise readings for solar installations, electrical systems, and industrial equipment. Its thin jaw is designed specifically for cramped spaces like combiner boxes or inverters. The non-contact design allows for safe connections without touching live wires, which prioritises safety at every step, while wireless connectivity eliminates the tangling of wires and allows for measurements from a safe distance.
With the digital multimeter and its wireless current clamp, technicians can measure voltage and current simultaneously and automatically calculate VA power. This feature eliminates the need to change the measurement setup. Measurements can be transmitted to a smartphone or tablet for detailed analysis.
