Another 70 metre Palfinger for Extreme Wind

UK based Extreme Wind Services has purchased another 70 metre Palfinger WT700 from distributor Skyking for wind turbine maintenance work in the UK.

Extreme specialises in the servicing of wind turbines combining a cleaning service with inspection, video analysis and non-destructive testing, including ultrasonic, acoustic and thermography. Resultant blade repair services can also be scheduled by the operator to help prolong the life of the blades.

Skyking supplied Extreme’s first 70 metre platform in 2009 and have worked closely with the company to ensure that the platform can safely accommodate the company’s specialist attachments which clean and inspect the blades. The machine has provided trouble free service during the period.

Aerolia runs up A350 panel production

EADS' France-based aerostructure subsidiary Aerolia plans to deliver the first two Airbus A350 cockpit fuselage sections this summer in continuation of the former Airbus operation's tradition to build the "front end" of the European aircraft family. However, the target for the company is to be sold to an external investor and to balance out its nearly exclusive Airbus workload against other manufacturers.

Production is running up in the new 18,000m² (194,000ft²) composite unit at Aerolia's assembly site in Méaulte, 30km (18 miles) northeast of Amiens, which opened at the end of November 2010, even though means of production were still being installed in late May. The first A350 nose fuselage section is to be delivered "between June and September", says chief executive Christian Cornille, adding that the second one is to follow "within a month".

Non-Destructive Compression Testing of Concrete

Introduction

The use of the non-destructive testing methods for determining the compressive strength of high performance concrete ensures high quality. Compressive strength test results are mainly used to determine whether the concrete mixtures used meet standard specifications. Structural failures because of concrete mixes that do not have the necessary strength for the specific application can be catastrophic and may lead to loss of life. Hence it becomes extremely important for construction companies to carry out such tests prior to opening structures such as buildings for service. Non-destructive testing also has the advantage that it is quicker and far more economical than destructive testing on samples.

Bluestream Comeback Marked By ROV Order

An order on Saab Seaeye for a new Cougar XT light-work ROV is markting Bluestream's comeback in the market. The Netherlands-based offshore subsea and rope access services company will use the ROV for light construction tasks, remote tooling, HP cleaning, diver support, salvage, drill support, well intervention, non-destructive testing, pipeline survey work, inspection, repair and maintenance. The ROV will join their fleet of five Saab Seaeye Tigers, and two Surveyor Plus systems.

Managing director of Bluestream, Rolf de Vries, says there is a strong focus within Bluestream's business model on ROV support services, in addition to contracted diving and rope access services.

Ronacrete provides concrete repair and protection in Hove

Elastomeric anti-carbonation coating and anti-carbonation coatings used to protect high-rise flats from sea damage. Concrete Repair & Protection range.

Ronacrete products were used in the restoration of 1 Grand Avenue Hove, a late 1960/70s multi-storey private residential block situated in a prime seafront location.

As is common in coastal locations, the reinforced concrete elements of the building had suffered severe deterioration, including spalling to the concrete of private balconies and to ring beams. More critically, the ring beams supporting the outer brick skins of the flank walls had suffered serious structural damage, with an imminent risk of failure of the brick cladding.

The main contractor Ellis Builders of Eastbourne appointed Cemplas Waterproofing and Concrete Repairs Limited to undertake over £100,000 worth of specialist remedial repairs.

Permeable Concrete Tested To Reduce City Street Flooding

The drainage system in New Orleans is so strained that after ten minutes of rainfall, cars wade through ponds on the street and pedestrians wear rubber boots just to reach the corner drugstore. To minimize those sloshes, city officials, along with green-builders Make It Right Foundation and others, are experimenting with pervious pavement--a porous material with an underlying layer that captures water and oily contaminants.

Cedric Grant, New Orleans Deputy Mayor of Facilities, Infrastructure and Community Development, said last week that the city is testing the benefits of using pervious concrete in the Lower Ninth Ward.

"About 300 feet of heavily deteriorated asphalt on North Prieur Street between Jourdan and Deslonde was repaved with pervious concrete this spring," he said. That was the first local, street application of the material. "The city partnered with Hard Rock Construction, Lafarge North America and the Make It Right Foundation to test this project."

University of New Orleans engineering students did the design work needed to pave the project's single, city block.

"At this time, the city is testing the installation of the newly paved road for strength and durability," and to see whether pervious concrete can drain water from streets, Grant said. He noted that "all Make It Right homes utilize pervious concrete sidewalks and driveways, totaling more than 35,000 square feet in the Lower Ninth Ward."
