Re: MSC Napoli - the salvage teams are coming back.
At about 1445 hours earlier today I noticed a fixed wing aircraft about 2 miles south of the wreck site appearing to spray a substance on the water from a low height - it then climbed and headed inland across Branscombe.
It may have been either a treatment detergent or possibly dumping fuel.
The crane barge currently working out at the wreck site is the Missing Link - operated by Hapo Barges. Other examples of the 'missing link' can also be seen in Sidmouth leaving Carina's every weekend at about 2 am.
Interested watchers would have noticed the tug and crane barge leave the area a couple of days ago - they moved to a position just north of Torbay, probably to shelter from recent winds.
They are now - as of 1500 hours today - due south of Sidmouth heading back to the wreck site where they will be joining offshore supply boat Captain Joe which is already on station.
Recent work at the wreck site appears to have been successful:-
DRILLING SUCCESS AS REMOVAL OF MSC NAPOLI’S STERN PROGRESSES
The operation to remove the stern section of the container vessel MSC Napoli from the East Devon coast has passed its first milestone.
The project team, led by Global Response Maritime B.V. of The Netherlands, has successfully positioned the first of a series of lifting chains under the wreck by underwater drilling.
The first chain was positioned by a special subsea drilling system. This task marks the first successful, totally subsea, use of the drilling system in an offshore wreck removal. A novelty in the history of salvage.
Twelve lifting chains are being drilled into position under the stern, which has a weight of around 3,800 tonnes. All 12 chains should be positioned by the end of April although operations of this type, naturally, are weather dependent.
The MSC Napoli became a casualty during a violent Channel storm in January 2007. The vessel was beached deliberately, in order to prevent total loss. Subsequent operations, by other contractors, recovered bunkers, containers and the forepart of the ship.
The drilling system employed consists of a 110 tonnes subsea drilling module powering a remote-operated, transponder-guided drilling rod. The first lifting chain was pulled into place on withdrawing the drilling rod. The drilling and positioning of the lifting chains was subcontracted to a joint-venture consisting of Belgium company DISA, specialists in subsea works based in Beerse, and drilling technologists Gebr van Leeuwen Boringen of Harmelen, in The Netherlands. Another subcontractor, Hapo International Barges, has mobilised the crane barge Missing Link, now acting as the main surface platform for the project team.
With all lifting chains in position, the main operational phase will commence in early May. Global Response Maritime will mobilise two 140 m flat-top barges rigged with heavy mobile cranes, together with two support tugs. A series of 24 chain-pullers, installed on the flat-top barges, will be connected up to the lifting chains ready on location. The two lifting barges will be moored parallel to MSC Napoli’s stern. When preparations for the main lift are completed, the barges will be ballasted down, to compensate for the forces acting on the pullers and reduce movement in the swell.
Global Maritime Joint Managing Director Paul Glerum added:
“Having brought MSC Napoli’s stern to the surface with the pullers, wreck sections of around 100 tonnes each will be cut and lifted onto the main decks of the barges, using the mobile cranes. This work will progress until total weight is reduced to around 1,200 tonnes. At that point a decision will be taken on whether to lift the remains as one unit, or to continue to cut until the weight is within the capacity of the larger of the two deck-mounted cranes (rated at 500 tonnes). This crane will also recover the poop deck, rudder and propeller, which are all already detached from the stern.”
Global Maritime Joint Managing Director Klaas Reinigert said:
“There is nothing new in drilling under a wreck. What is new is drilling entirely subsea, without the use of jack-ups or working from a quayside. The success of the subsea drilling system is crucial to our wreck removal plan.
Hugh Shaw, the Secretary of States Representative in Maritime Salvage and Intervention said
" I am delighted with the progress to date. There is still much work to be completed however the success of the entire operation crucially depended on the ability to drill below the wreck in order to place the lifting chains. This has now been successfully achieved and the methodology has been proven. Subject to weather conditions, it is likely that this phase of the operation will be completed ahead of schedule".
Tug Eurosund and tow - crane barge Missing Link have now left the wreck site and heading back to Rotterdam. They've done well if they've managed to get all 12 lifting chains in place - at least a month ahead of schedule.
The operation to remove the stern section of the container vessel ‘MSC Napoli’ from the UK’s Devon coast has reached its second milestone.
A multicat style workboat delivers chains to the crane barge.
Following a successful test, the project team, led by Global Response Maritime B.V. of The Netherlands, has completed positioning all 12 lifting chains under the wreck.
The 12 lifting chains were put in place by a revolutionary subsea drilling system in less than three weeks. This marks the first successful, totally subsea use of the drilling system in an offshore wreck removal.
The drilling system employed consists of a 110 ton subsea drilling module powering a remote operated, transponder guided drilling rod. The first lifting chain was pulled into place on withdrawing the drilling rod. The drilling and positioning of the lifting chains was subcontracted to a joint venture consisting of Belgium subsea specialists DISA and drilling technologists Gebr van Leeuwen Boringen of the Netherlands. Another subcontractor, Hapo International Barges, mobilised the crane barge ‘Missing Link’, which is now acting as the main surface platform for the project team.
With all lifting chains in position, the main operational phase will commence in early May. Hapo will mobilise two 140m flat-top barges rigged with heavy mobile cranes, together with two support tugs. A series of 24 chain pullers, installed on the flat-top barges, will be connected up to the lifting chains now on location. The two lifting barges will be moored parallel to MSC Napoli’s stern. When preparations for the main lift are completed, the barges will be ballasted down to compensate for the forces acting on the pullers and reduce movement in the swell.
When the MSC Napoli’s stern section has been lifted to the surface with the pullers, wreck sections of around 100 tons each will be cut and lifted onto the main decks of the barges, using the mobile cranes. This work will progress until the total weight is reduced to around 1,200 tons. At that point a decision will be taken on whether to lift the remains as one unit, or to continue to cut until the weight is within the capacity of the larger of the two deck mounted cranes.
Recent reports are that there are some 'sheerlegs' and a couple of dutch tugs loitering at or off Portland - this could be a massing of the troops for the final push.
Re: MSC Napoli - the salvage teams are back - really.
The salvage teams have returned to our waters today - probably to book some bank holiday overtime.
Earlier today, tug Eurosund returned with crane barge Missing Link in tow accompanied by a smaller, as yet unidentified, work boat. Tug Mustang has just rounded Portland Bill and should be on scene later tonight.
Expect a few more assets to arrive very shortly - interesting times are ahead.
Re: MSC Napoli - the salvage teams are back - really.
The two cranes are right over the wreck this morning - it certainly looks as though the final stage has started. My only concern is that this phase will disturb the resting stern section and there is certainly a chance that any remaining heavy oil will be disturbed. I hope they will have a boom deployed.
