Earlier this month, Thialf and our team completed the offshore operations to remove the Kinsale platforms on behalf of our client PSE Kinsale Energy Ltd, and now the last of the decommissioned structures have been safely moored at the Hoondert Services & Decommissioning (HSD) location in Vlissingen.
The project included removing the Kinsale Alpha and Bravo platforms, which were the only two platforms in Irish waters.
In total, we removed 24,000 metric tons of steel, and 97% of this material will be reused or recycled ♻️
The infrastructure removed during the decommissioning project includes:
- 2 topsides
- 4 accommodation modules
- 14 conductors
- 2 jacket top sections
- 2 bottom sections
We want to thank everyone involved for their contribution to the completion of the Kinsale project! This includes our client, team, and all subcontractors involved in the preparation and ex*****on of the project onboard Thialf and in the yards.

📣 Last week, Heerema Marine Contractors' Aegir installed jacket 111 out of 111 for Ørsted's Greater Changhua offshore wind farm, reaching another key milestone for the project!
This achievement would not be possible without our team, and we congratulate them for their hard work! With grouting operations now complete, the next step for these final jackets is to install armour rock protection to protect the structures against scour.
Earlier this year, Heerema Marine Contractors installed Equinor’s Johan Castberg FPSO lower turret for our client Aker Solutions. Now, these two giants will meet again!
Sleipnir will soon install the remaining structures, namely the manifold and gantry module, at the Aker Solutions quayside in Stord, Norway.
22/08/2022
Last week, Heerema Marine Contractors' Aegir and our team successfully installed the first three 100% Taiwanese-made foundation jackets for our client Ørsted's Greater Changhua offshore wind farm! The SDMS constructed jackets were loaded out from the Sing Da Harbor in Kaohsiung City, Taiwan, on Sunday and installed on Thursday morning.
The jackets are specially designed to perform under the unique local weather and seabed conditions, with a height of around 80 meters.
We are proud to be a part of this important milestone for Taiwan's offshore wind industry!

Sleipnir's cranes can each lift an enormous 10,000 metric tons, almost the same weight as the Eiffel Tower!
The cranes were constructed and delivered by Huisman and can lift this heavy weight due to a range of specially designed engineering details. One interesting feature is that the cranes each have a winch room at the back that we call the 'backpack,' which also acts as a counterweight and keeps everything in balance. Sleipnir's crane booms can also be raised in only ten minutes, and the cranes can rotate using their custom-designed slew bearing system.
Another important feature is the cranes' redundancy, which means that they have extensive backup systems that are duplicates of critical components.
Start making an impact with a career at Heerema and join us in making the impossible possible! At Heerema Marine Contractors, we do something new every day. We operate the world’s largest crane vessels, and with them, we transport, install, and remove offshore structures for the energy markets. Our projects range from installing huge offshore wind monopiles to removing decades-old oil and gas platforms, as well as being able to install platforms up to 50,000 metric tons! You will play an important part in our unique maritime adventure by joining us.

Sleipnir's crane hooks are the world's largest, each capable of lifting 10,000 metric tons, but constructing these giants was no easy task!
The hooks were made using a unique process of casting, where molten steel is poured into a specially engineered mold made of clay.
Some interesting facts about constructing Sleipnir's crane hooks:
⚖️ 240 metric tons of steel were used for each hook
↕️ 6.5 meters high
📅 4-5 months were required for the cooling down process
After the long cooling process was complete, we tested the hooks with 40% more than Sleipnir's maximum load (as seen below). This action means that both huge hooks lifted 14,000 metric tons on two prongs!

Not your everyday office view! As seen from Aegir, these wind turbine jacket foundations were recently installed by Heerema Marine Contractors for Ørsted's Greater Changhua wind farm.
There are several steps involved in installing one of these jackets! The first is leveling the seabed and installing a layer of filter rock. Then we place the Heerema Fabrication Group constructed pre-piling template onto the filter layer and drive the pin piles to pe*******on using the template to ensure correct placement. While we work on pile-driving, we use noise mitigation measures to ensure we are protecting the local marine life. 🐬
After Aegir has installed the piles, we can move on to the jacket installation after cleaning any marine growth inside the piles. Once the jacket is in place on the piles, we secure it by grouting, and later the structure is protected against scour with armour rock protection.
Once these steps are finished, the jacket has been successfully installed! ✅

Why do we transport decommissioned structures in our cranes? 🏗️
There are many reasons, but mainly because it can reduce time and steel use and is a safer way to ensure decommissioned structures are delivered for reuse and recycling! ♻️
Where possible our crane suspension transport method removes weather sensitivities by avoiding the need for backloading barges and securing the structures with seafastening offshore.

Last week, Heerema Marine Contractors and consortium partner AF Offshore Decom successfully completed the Brae Alpha West Drilling Rig and Brae Bravo upper main jacket removal on behalf of our client TAQA Group.
The project involved safely removing and transporting more than 12,000 metric tons of steel to the AF Offshore Decom yard in Vats, where it will be reused and recycled by more than 95%.

The PSE Kinsale Energy Ltd Bravo deck and topside have returned to shore! This short video shows the roughly 3,600 metric ton jacket being transported from barge H-541 onto the quayside at the Hoondert Services & Decommissioning (HSD) yard.
To load in a structure like this, we must use ballasting to ensure everything is level and aligned with the quayside. This action was achieved by using both H-541’s internal ballasting system and Mammoet’s ballast pumps to displace a massive 25,000 cubic meters of water!
Next will be the load-in of the Kinsale Alpha topside and jacket top section, various accommodation modules, and the jacket bottom sections.
Once finished, the Kinsale platforms will be recycled around 97% ♻️
