EFFICIENT LIFTING AND LOAD-OUT OF SUCTION ANCHORS, EGYPT SECTOR: » Oil and Gas

KEY BENEFITS: » On schedule » Increased safety » Minimised disruption

PROJECT: ALE has demonstrated its efficiency when performing the lifting and load-out of four suction anchors, weighing between 185t-220t, for the Zohr gas project in Alexandria, Egypt.

ALE had a tight timeframe to complete the manoeuvres and needed to ensure that all remaining port operations could continue uninterrupted.

At the Port of Alexandria, ALE used an 850t capacity crawler crane, operating with a radius of up to 30m, to transport the suction anchors, weighing 185t, 190t, 215t and 250t, from the storage area to the side of a barge.

ALE then used the same crane to load-out the suction anchors onto the barge.

In addition to these pieces, ALE loaded-out other smaller parts, including an upper circular hub, weighing 65t, and a rectangular ladder piece, weighing 95t.

ALE completed the installation of all the parts safely and within the deadline set by the client while also managing to minimise disruption at the port.

The Zohr gas field is the largest ever natural gas discovery in the Mediterranean Sea and the project is being developed 150km from the Egyptian coast.

CHALLENGING 2,100KM TRANSPORTATION OF ENGINES ACROSS FOUR COUNTRIES, GHANA TO GUINEA SECTOR: » Mining

KEY BENEFITS: » In-house logistics expertise » International transportation experience » Innovative equipment

PROJECT: ALE has completed the transportation and installation of three engines, weighing 153t each, at Siguiri Mine, Guinea, working alongside Rohlig France’s Project department, who were the freight forwarder for the operation.

ALE used their Trojan truck as part of the convoy to transport the engines from the Port of Takoradi, Ghana.

The engines had to be transported 2,100km over demanding roads of variable quality. They also needed to pass through four countries: Ghana, Burkina Faso, Mali, and Guinea, before arriving at a power plant on a mining site at Siguiri, Guinea.

At the power plant, ALE placed transport beams under the engines using a fixed gantry for the jacking points. The engine and alternator were then installed by jacking them down in two stages.

ALE completed the operation in just eight weeks.

ALE’s vast experience enabled them to overcome several challenges. The administrative procedures of crossing three country borders were managed by carrying out detailed planning in advance of the transportation.

Additionally, the capabilities of ALE’s Trojan truck made it easier for ALE to negotiate the poor road conditions. This and the other equipment selected for the operation were chosen because they were especially resistant to the route’s harsh conditions.

This was part of the power plant expansion at Siguiri Mine, which plans to have the new facilities in operation by the end of 2018.

SWIFT MOBILISATION FOR GUY WIRE MAINTENANCE IN OMAN SECTOR: » Oil and Gas

KEY BENEFITS: » Short mobilisation

PROJECT: Conbit was contracted to perform the tensioning work on a flare stack for OXY OCCIDENTAL in Oman.

The end termination of the wire ropes had to be reinstated to the prescribed minimum of seven cable claps per connection. To perform the guy wire maintenance, Conbit utilised PIAB guy wire tension measurement equipment and total station for verticality check.

One of the challenges Conbit faced was the mobilisation of the crew with calibrated equipment within a short timeframe. The client was impressed with Conbit’s swift action and successful execution.

Conbit based the engineering tension values on the temperature as they recognised the impact they had. They engineered the new tension values, ensuring that the final pretension values and angle deviations were within the prescribed pretension values of -10%/+15% or within a pretension tolerance of -15%/+20%. By cross-checking the influence the temperature had on the values, Conbit could determine a more precise measurement of the pressure.

INNOVATIVE CRANE ACHIEVES RECORD-BREAKING LIFTS OF FPSO MODULES IN NIGERIA SECTOR: » Oil and Gas

KEY BENEFITS: » Innovative equipment » Reduced costs » Aids overall production schedule » Bespoke solution » Record-breaking

PROJECT: Using its unique and innovative AL.SK350 crane, ALE has been able to break another world record to lift modules as heavy as 3,000t during its contract lifting and installing six FPSO modules for Total’s Egina FPSO module integration project in Nigeria.

For Total’s Egina project, ALE was contracted to lift and install six modules from the yard onto their final position on the FPSO. The lift weights were between 335t and almost 3,000t.

An engineering feat like this was only achievable by using the AL.SK350 crane, the world’s largest capacity land based crane.

For the 3,000t lift, it was rigged in its biggest configuration with a 124m a-frame main boom, 49m ballast radius and a newly developed 38m heavy duty jib for additional outreach, along with a heavy winch system and 4,000t ballast.

The jib, with a patented design, was used for the first time on this project. It boosted the overall lifting capacity and extended the outreach so the crane could be strategically positioned to lift from one location. As the yard has restricted space, this configuration was the ideal solution and reduced the overall project schedule.

The crane has also provided significant time and cost savings to the client as it has allowed them to build fewer, yet bigger modules locally.

“The project really showcases the capabilities of the AL.SK350 and the jib to perform some of the world’s heaviest ever crane lifts in a congested site. When combined with the unique heavy duty jib and the largest crane configuration, this represents another record-breaking achievement for ALE,” explained Carlito Alberto, ALE Project Engineer.

The client also praised ALE’s work: “I want to thank the ALE crew on behalf of SHIMCI for their outstanding efforts that allowed us to complete 100% of the expected lifts before the first shipment. Despite challenges on site, ALE has been able to complete the lifts on time,” commented the SHI-MCI Egina Project Manager.

GAS TURBINE DELIVERY DEMONSTRATES TEAM CO-ORDINATION, IRAQ SECTOR: » Oil and Gas

KEY BENEFITS: » Extensive equipment fleet » Multi-service operation

PROJECT: ALE has successfully received, transported and installed four gas turbines and four gas turbine generators for the Zubair Oil Field Development Project, Iraq.

The heavy equipment was shipped to Umm Qasr Port, where ALE received and transported them to the temporary storage area inside the port on 16 axle lines of hydraulic trailers in a 4 file 8 configuration.

The gas turbines, weighing 357t, and gas turbine generators, weighing 234t, were stored whilst clearing customs. ALE then reloaded the items onto the trailers and transported them over 70km to site.

The route was very challenging and involved negotiating several high, medium and low voltage power lines that needed to be shutdown to allow safe passage of the transport convoy.

Once the heavy equipment arrived on site, they were delivered to their foundations and installed using ALE’s heavy duty jacking and skidding equipment.
