Project:

ALE has delivered an integrated solution to help complete a phase of a major offshore project in Mexico.

The global heavylifting contractors were tasked to perform weighing, jacking, load-out of the jacket and the platform.

The first stage of the three-phased project involved the 14m-high jack-up of the topside, weighing over 13,000t, using ALE’s innovative Mega Jack system. As the Mega Jack had its own starter beams, and has quicker assembly and jacking speeds, it is much more efficient than other systems on the market.

ALE configured the Mega Jack with eight towers, each with 5,200t capacity. This provided the strength needed to lift such a heavy weight whilst evenly distributing the ground loading pressure. The topside was jacked-up to 14m high in stages. Upon reaching the first jacking phase 5.5m high, the client could access the forklifts under the topside, which was a major advantage as they could continue operations and optimise the project schedule.

For the load-out of the topside, ALE – Offshore Services was the specialist team who designed and supplied the rapid ballasting system, with a system capacity of 16,000 Cu.M/Hr, as well as the associated ballast pipework specifically for this operation.

With a combined weight of almost 17,000t, ALE’s experienced offshore team worked in two shifts to pull the topside a total distance of 196.63m. By using strand jacks and kicker jacks to pull the topside onto the client’s barge, ALE completed the load-out in a timely manner.

The final stage involved the floatover in the Gulf of Mexico. Six 24PS ballast pumps, 18 10PS de-ballast pumps and ten 380HP HPUs were installed onto the client’s barge, along with associated ballast pipework.

Health, safety and the environment (HSE) was a paramount consideration throughout and underpinned the entire project. ALE ensured all operations were supervised centrally in real-time to ensure operational flow.

“This is a fantastic achievement for all of the ALE teams involved. Throughout this project, we have established a strong on-site partnership to meet our client’s technical and operational needs,” explained Simon Armstrong, Project Manager for ALE – Offshore Services.

“By finding a solution that could integrate our systems easily with the client’s needs, we delivered effective methodology, and the proven upscaling of the yard makes it a more attractive site for future operations.”
