Maritime Developments Ltd (MDL) and Jumbo Maritime have accomplished a deepwater polyester mooring rope set up within the Gulf of Mexico.
The challenge moored a brand new floating manufacturing unit (FPU) at depths of 1,200m (4000ft). The operation was carried out utilizing an MDL mooring unfold mobilized on-board Jumbo’s Heavy Load Service, the Fairplayer.
The MDL unfold consisted of a Technology 1 Reel Drive System and stage winder for exact transpooling of mooring line ropes from a complete of 24 transport reels onto a purpose-built, heavy-duty deployment reel; in addition to a Technology 2 Reel Drive System for the overside set up of the product.
The polyester rope transport reels had been mobilized on deck in two parallel bays, permitting for 15 reels to be dealt with on the highest deck, with the remaining reels deployed from the center deck.
The specialist 8.6m OD set up reel was designed by MDL’s in-house engineering crew and includes a spoked part to separate the polyester rope and mooring chain. The reel had a twin perform on the challenge: firstly, permitting the transpooling of the product from the storage reels beneath again rigidity, and secondly for deployment of the traces overboard. MDL Technology 2 RDS’ 150Tem of torque allows dealing with of a great deal of as much as 75Te, revving in each instructions.
An extra bespoke characteristic designed and manufactured by MDL was a skid body to permit the HPU to skid with the Technology 1 RDS down the tracks.
This challenge was the primary joint set up by MDL and Jumbo within the Gulf of Mexico, however follows different mooring scopes within the Mediterranean and offshore Brazil in 2020-21.
Paul Marshall, MDL Venture Engineer, mentioned, “From the onset MDL and Jumbo collaborated as One Group to assist every shopper and mooring challenge at each stage. We acquired excellent suggestions, the place each our on-board and office-based groups have been acknowledged for his or her professionalism, proactive and educated strategy, and our gear to be match for Jumbo’s asset.
“Contemplating the variety of reels to be deployed, the mixture of a giant again deck and our compact however extremely succesful gear resulted in a fit-for-purpose resolution that was way more environment friendly than utilizing conventional approaches, reminiscent of deploying an Anchor Handler.
“The Fairplayer’s mixed footprint on the higher and center deck meant that the entire set up was carried out in a single journey – decreasing the price and impacts of port calls, transit and the general size of the mission.”
Andrew Blaquiere, Managing Director at MDL, mentioned, “I’m so happy that our profitable collaboration with Jumbo has delivered efficiencies to a Gulf of Mexico operator and their new improvement start-up. This challenge has allowed us to show that there are various approaches obtainable even for conventional operations reminiscent of moorings – and for deepwater basins.
“MDL is creating a status for figuring out new, leaner, safer approaches to conventional operations, to assist challenge groups meet their schedule and funds targets in an more and more demanding market. That’s precisely the place we need to be.
“Our in-house mixture of market-leading, moveable and adaptable gear, along with PM&E expertise and a long time of collective experience, permit us to successfully analyze the problem at hand and formulate an answer – both to go well with the shopper’s fleet or any vessel they’ve handy entry to.”
Within the meantime, an set up of a sheathed Spiral Strand Wire Rope (SSWR) within the APAC area is utilizing an MDL mooring unfold with a 4-track tensioner because the grasp system to moor in an FPSO.
Up to now, MDL gear has put in over 145km of polyester rope, in addition to torpedo anchor pennants SSWR and metal wire rope, throughout three continents.
