Cadeler F-class can convert from being a basis set up vessel (WFIV) to a wind turbine set up vessel (WTIV)
The two X-class and two F-class vessels on order on the COSCO Heavy Industries shipyard in China for Danish wind turbine set up vessel specialist Cadeler A/S will use a mixture of medium- and high-speed MAN engines to allow them to ship the biggest lifting capability up to now seen within the section.
Scheduled for supply from 2024 via 2026, Cadeler’s X-class vessels are designed to function at among the most troublesome websites across the globe with a deck area of 5,600 sq. meters, a payload of over 17,600 tons and major crane capability of >2,000 tons at 53 meters. The F-class has comparable specs however is uniquely versatile and could be rapidly transformed from a foundation-installation unit to a wind-turbine-generator set up vessel.
”We are at present constructing 4 distinctive, pure-play, offshore vessels that goal at putting in the foundations and wind generators of the long run,” mentioned Cadeler’s CEO, Mikkel Gleerup. “In order for our vessels to optimally operate, we need engines that meet our requirements by delivering the needed lifting capacity. Our cooperation with MAN has been a good and steady one throughout the years. We chose them as supplier as they have demonstrated the ability to deliver a product that is innovative and of high standard, which will be a good fit with the rest of the vessels’ capabilities.”
Each vessel will function an engine configuration primarily based on a combined MAN medium- and high-speed engine idea with two 6L32/44CR and two 9L32/44CR medium-speed engines plus two 12V175D high-speed engines. Each engine may even function SCR (Selective Catalytic Reduction) and meet IMO Tier III emission requirements.
“This is a unique application that will set a new standard for offshore turbine installation and sustainable marine operations, as well as being a great showcase for our mixed-engine concept,” mentioned Elvis Ettenhofer, head of marine four-stroke APAC, MAN Energy Solutions.”With its reliability and lengthy occasions between overhauls, the 175D has the DNA of a medium-speed engine, which is why it matches so effectively with our 32/44 items. Only MAN can present this distinctive engine-configuration with the best effectivity, decrease weight and a better payload; this represents actual worth for our buyer, Cadeler.”
The F-class jack-ups will be capable of transport and set up seven full 15MW turbine units per load or six units of 2XL monopile foundations per round-trip – a considerable enchancment in effectivity over present vessels. The vessels may even function a singular design that allows their conversion from foundation-installation to wind-turbine-installation vessels (WTIVs).
The MAN medium and high-speed engine idea includes frameless 2 × MAN 6L32/44CR + 2 × MAN 9L32/44CR + 2 × MAN 12V175D engines and presents an a variety of benefits:
- area financial savings – together with small complete genset footprint and compact SCR sizes – minimises engine room and funnel area, resulting in bigger deck space;
- optimized energy/weight ratio with the combined engine idea together with the frameless design for the medium-speed 32/44CR engines. In this occasion, the full engine weight of the Cadeler undertaking is round 200 tonnes. This is a brand new benchmark that saves gas, CO2 emissions and will increase the payload
- optimized OPEX via low SFOC throughout low-load operation and off-engine when not required. This delivers an environment friendly gas consumption and decreased engine-operating hours
- elevated redundancy – the 32/44CR and 175D lead in engine dynamics and cargo ramp-up. Hence, it’s doable to have a minimal variety of gensets on-line
The engines are outfitted with the newest era of common-rail programs and could be tailored to function on low or impartial CO2 fuels.
