Decommissioning of disused oil & gas facilities are big business around the world as a lot of fields are becoming depleted and the authorities demand that all infrastructure, above and below surface, are removed and the seabed returned to it’s original condition.

Plugging and abandoning wells to ensure there will be no leaks in the future is important.  
Doing so cheaply and efficiently has become challenge especially sub sea wells in deep waters. This usually requiring full size drilling rigs and can take weeks and months to complete.  
Special riser less methods have been developed to allow smaller and cheaper vessels to perform this task:

Removing platform topsides and jackets has been done by cutting and lifting. This is costly, time consuming and represent a safety risk.  
Allsea’s Pioneering Sprit can reduce both cost, time and safety risks by lifting and transporting heavy topsides and jackets in one piece:

Unfortunately the P.S. cannot be used in the GoM due to local restrictions on foreign vessels transporting recovered topsides or jackets to a US port for demolishing.  
The alternative would be to do the demolishing in some other nearby country, or i

Makes me feel old.  
I was Towmaster for the towout of the Gyda jacket in 1989. Standing upright on the transport barge M-44 (LOA 600’ / 60000 DWT)  
Seen here at loadout in Verdal, Norway:  
 ![Gyda 1 (3)](https://us1.discourse-cdn.com/flex016/uploads/gcaptain_maritime_forum/original/3X/c/8/c88852c7a9b2987711fe64f0bdfd747aa1792fb4.jpeg)  
The jacket with slings and spreaders weight in at 8500 m.t. and stood 120 m. asl.

Under tow to the field;  
 ![Gyda 2 (4)](https://us1.discourse-cdn.com/flex016/uploads/gcaptain_maritime_forum/original/3X/c/3/c3babc5b7c9723f263f4b35a013b181c7f5c60a6.jpeg)  
Yes there is a 600’ barge under the jacket.

Delivered under the cranes of the SSCV Micoperi 7000 (now Saipem 7000):  
 ![Gyda 3 (3) (390x492)](https://us1.discourse-cdn.com/flex016/uploads/gcaptain_maritime_forum/original/3X/1/c/1c62313bb9eb408047e85ac35bd5e5ec5d5e5572.jpeg)

Lifted off the barge and set over a predrilled template on the seabed:  
 ![Gyda 4 (3)](https://us1.discourse-cdn.com/flex016/uploads/gcaptain_maritime_forum/original/3X/2/f/2fcacdb5049712b29f1140d8f881384cba0399d2.jpeg)  
This was the heaviest offshore lift ever performed at the time.

PS\> Looks like the jacket has grown in weight since installation. (Maybe it’s inflation, or OE operate in Short Tons)

PS\> I was on a ship that brought in supplies at the early stage of construction of the bauxite mine and processing facilities at Gove (1969-70)  
When we delivered the first cargo there were just an old pier from an earlier mission station, a camp and mess tent for the workers clearing the site for development of a large open pit mine, the processing plant (refinery) an air strip and the port facilities.

> [@](#):
>
> **Heerema Marine Contractors** and **AF Offshore Decom** have secured three contracts covering the removal and disposal of offshore platforms weighing more than 120,000 tonnes combined in the UK North Sea, setting up a multi year heavy lift and recycling campaign.
> 
> The contracts were awarded by an unnamed North Sea operator and cover the engineering, preparation, removal and disposal of three platforms. Heerema said the projects are expected to be completed within the next decade.
> 
> For the offshore transport and heavy lift market, the scale of the structures makes the programme a substantial decommissioning logistics operation. Removed infrastructure will have to move from offshore lifting sites to an onshore dismantling facility in Norway.
> 
> Once lifted and transported from their offshore locations, the structures will be delivered to AF Environmental Base Vats. The facility will handle the onshore dismantling, recycling and disposal stage of the programme.  
> Heerema said the complete programme is expected to be finished within the next decade, giving the consortium a long term offshore removal and recycling workload in the UK North Sea.
