Aarsleff BIZ together with client Van Oord carried out a Mock-up test of the Fryslan OWF Concrete Work Platforms (CWPs).
The purpose of the – successful executed - CWP Mock-up test was to simulate all the steps of Van Oord operations regarding the lift and installation of the CWP as they are planned to take place during offshore operations later this year.
In that regard the installation methods, the lifting/rigging plans, EPIC (External Platform Installation Cone) installation guide, tag lines and winches were assessed to avoid potential mistakes prior to Van Oord’s offshore works execution.
Additionally, the Mock-up CWP (which also will be installed offshore) was weighed with loadcells to verify the design weight.
Today we have sailed out two giant 2000t concrete caisons to the Port of Ystad.
They will be directly submerged from the barge and placed on the designed location during coming weekend. The production lasted since November 2019. See video from this project in the project tab.
Today we have completed last major milestone in constructing two 2000 ton caissons for Ystad Harbour
We have installed deck elements on both caissons, each consisted of 4 precast concrete elements weighing 60 ton each. Operation took several hours without the need of rotating of the barge.
We have delivered full ship with the elements for the Expansion of Port of Skagen — Phase 3.
The concrete precast elements are front wall elements of the quay wall, suitable for both sheet pile walls and combi walls (371 units). Besides that we have produced 50 units of 15m and 18m long reinforcement steel cages ready to install in the new quay wall construction. In total we have delivered 850 tons of concrete and reinforcement steel elements.
115 pcs of L-walls combi-wall
256 pcs of L-walls sheet pile wall
44 pcs of 18m reinforcement cages
6 pcs of 15m reinforcement cages
96t of loose reinforcement steel rebars
AARSLEFF BIZ ongoing with production next 2 giant 18m high caissons.
2000t structures to depart in April 2020 and to be submerged at the port of Ystadt.
OFFSHORE CONCRETE WORKING PLATFORMS in 2020
„We are pleased to announce that we have been awarded with 2 offshore contracts for production of CWP in 2020. We will produce 165 pcs of platforms for Hornsea 2 Project in UK as well as 89 pcs for FRYSLAN Project in Netherlands. It is a big challenge for us and require an extreme casting schedule of one platform each working day.”
We have performed the skidding operation of 2 heavy reinforcement cages XXX ton each on Carrier 16 barge deck. This operation will begin the on-barge production of two Caissons structures (2500t each) for Ystad harbour. The plan is to completely fabricate, deliver and submerge the caissons before May 2020.
COASTAL VIRGINIA OFFSHORE WINDFARM
„AARSLEFF BIZ has produced and shipped 2 trial offshore concrete working platforms for US Coastal Virginia offshore windfarm. The platforms were shipped to Rostock were our installation team have assembled aluminum railings and other outfitting accessories.”
2 pcs of 90t offshore concrete working platforms for the US market
„We have loaded and sent out the last 3 ships with 43 pcs of special precast tunnel elements for the Copenhagen Airport. The 32 ton elements will be shipped to Koge harbour where they will be unloaded on trucks and transported directly on Copenhagen Airport site. We have produced 118 pcs of elements of 7 different sizes. Total of 3760 tons of element delivered on 3 ships within 2 months.
„The production of Cubipods’ is over. We have produced 3452 pcs of various elements with 22 000 m3 of concrete volume and 62 000 t total weight. Since May 2018 we have loaded and shipped 8 north sea barges to Denmark for Hansthom harbour expansion Project.,
„We have started a serial production of prefabricated concrete columns for 120 meters high Carlsberg Tower which will become the tallest residential building in Copenhagen”.
Production of precast concrete columns for:
⦁ Parking house: 789 pcs
⦁ Tower: 746 pcs
Concrete strength: C60/75
„Aarsleff BIZ just sent its biggest concrete element so far (16m high, 40m long, 23m wide and ca. 7.000 tons heavy) to Denmark (Hanstholm harbour). Watch our movie showing the production process.
„Aarsleff BIZ has started the production of various concrete precast elements for the Ystad harbour in Sweden. The plan is to deliver full range of elements, starting from small sized units like: anchor plates, quay wall front wall elements, going through light mast foundations, wells and ending up on 2 large scale Caissons of 2300 tons each”. This week we have loaded 129 pcs of anchor plates.
Anchor plates: 129 pcs
Quay wall front wall elements: 151 pcs
Wells: 40 pcs
Light mast foundations: 37 pcs
Caissons: 2 x 2500t
„We have completed all works and sent out last five Urban Rigger 2.0 floating pontoons. The great opening of all 5 ones is planned for October 2019”
„We have loaded out and sent fully packed Carrier 7 barge to Ronne Harbour at Bornholm. We completed this project since summer 2018 where we produced and delivered a wide range of various concrete elements e.g. anchor plates, cable wells with decks, quay wall L-walls, light mast foundations and 2 large precast ro-ro ramps 225 t each”
Ro-ro ramp 225t – 2 pcs
Light masts 43t – 13pcs
Cable wells and decks – 32pcs
Quay wall front L-wall elements: 336 pcs
Anchor plates: 327 pcs
L-walls A and B 16t – 30pcs
We are ongoing with production of 89 pcs of 75 ton cwps for Fryslan wind farm
We are planning to finish the project till the end of October. The platforms will be delivered on site in four batches by self loading ships.
