Update On Sunken Vessel On River Waveney At Bluneston Marshes. Now In The Middle Of The River


Recommended Posts

Dear all,

Update on sunken vessel on River Waveney (08 April)

The sunken vessel on the River Waveney at Blundeston Marshes has shifted position and is now in the middle of the river causing a clear and obvious obstruction. It is currently marked with yellow buoys and is being checked on daily.

The Authority is in communication with the owner of the vessel and given the hazard it is causing, we have contracted engineers to complete the removal operation before Monday 12 April.

Further updates will be issued by the Authority as appropriate, thank you for your cooperation.

Best,

Tom

Dear All

The vessel which was in the navigation channel at Blundeston Marshes on the River Waveney has now been recovered to a bay at the side of the river. The vessel is marked with yellow buoys and will be removed early next week.

Kind Regards

In case anyone was wondering (like me) this is about half a mile downstream of the junction with Oulton Dyke. 

Good to hear it's been moved out of the channel. Wonder what it was?

The vessel is marked with yellow buoys

They should, of course, be blue and yellow. Taken from "Guidelines on the provision and maintenance of local aids to navigation" published by Trinity House:

"7.1.2 Any AtoN established to mark a dangerous wreck is required to comply with the IALA Maritime Buoyage System. The use of the Special Mark Category for the marking of dangerous wrecks is not appropriate for this purpose. The use of Special Marks should be confined to marking wrecks of historical interest and those considered non-dangerous, but for which a surface marker is required for future location purposes."

And from the Trinity House website, the description of the correct buoy:

"Characteristics

The buoy has the following characteristics:

A pillar or spar buoy, with size dependent on location.

Coloured in equal number and dimensions of blue and yellow vertical stripes (minimum of 4 stripes and maximum of 8 stripes).

Fitted with an alternating blue* and yellow flashing light with a nominal range of 4 nautical miles where the blue and yellow 1 second flashes are alternated with an interval of 0.5 seconds.

If multiple buoys are deployed then the lights should be synchronised.

Consideration should be given to the use of a racon Morse code “D” and/or AIS transponder.

The top mark, if fitted, is to be a standing/upright yellow cross."

I thought Trinity House only dealt with matters relating to the sea.

Trinity house are also the body responsible for ensuring that aids to navigation deployed by harbour authorities etc. conform to the IALA standards. The Broads Authority is a harbour authority and the rivers are navigable by seagoing vessels, so all navigation marks should conform to the IALA standards. The document I quoted above is their guidance for local harbour authorities, which includes the BA.

It rather depends on if this particular wreck is considered dangerous or not. If it is purely causing an obstruction, then temp special marking is acceptable, I would think.

Surely an obstruction is, by definition, dangerous. If it's an obstruction It can be hit. And anyway, the Trinity house doc goes on to say:

"The use of Special Marks should be confined to marking wrecks of historical interest and those considered non-dangerous, but for which a surface marker is required for future location purposes."

The obvious one that occurs to me is the Mary Rose special mark in theeastern Solent. It marks the site of the Mary Rose wreck, where there is still significant archaeology and diving is restricted. It is in no way a hazard.

SIGNI, an interesting document and not yet adopted. As no UK inland waterway has adopted CEVNI and as we are no longer part of the EU, I cannot see it applying in the UK, but it acually has no conflict with the requirements for a harbour authority as defined in the Trinity House doc.  However it does use the same buoy as the IALA Temporary Wreck Marker for a new danger:

4.2.3 Marking of new dangers The term “New Danger” is used to describe newly discovered hazards not yet shown in nautical documents. New Dangers include naturally occurring obstructions such as sandbanks or rocks or man-made dangers such as wrecks.

Figure 4.3 Colour: blue and yellow vertical stripes in equal number dimensions (minimum 4 stripes and maximum 8) Form: pillar or spar Topmark (if any): vertical or perpendicular yellow cross Light (when fitted): Colour: yellow/blue. alternating Rhythm: one second of blue light and one second of yellow light with 0.5 seconds of darkness between.

Unfortunately the pictures won't copy from a PDF, but here is an image from another source.

maybe the different markings are a convention adopted for inland waterways, as techically as soon as you pass uder haven bridge you are no longer in a harbour area, 

i dont know, but the yellow post has been the standard marking on the broads as long as i know.

Technically, the whole of the Broads is a harbour area, at least to the extent that the Broads Authority carry out their navigational functions as a Harbour Authority. From the BA website:

"The Broads Authority (Pilotage Powers) Order 1991 confirms that the Broads Authority is a “Competent Harbour Authority” as defined the Pilotage Act 1987"

I am sure that they should terefore be applying the principles in "Guidelines on the provision and maintenance of local aids to navigation" although I suspect it isn't very high on Trinity House's list of things to check.

I cannot remember having read so much gobbledygook in all my life. It is in a river, on the broads.  A hazard. A danger. It is not high season. Is it not beyond the wit of man to move it.  Surely the BA have the resources to deal with this matter without all this silly malarkey.

Why are we even discussing the matter. Just move it.

I don't think there are many places to moor in that area although I seem to remember there is a little 'cove' on the left going upstream. I wonder if it had drifted before it sank?

up near thorpe I can recall several boats that had been run up onto the bank of the river, maybe the recent high tides refloated one of these and took it downstream, if it had been run up the bank due to hull damage, then understandably it would then sink, just musing out loud so to speak. doing what the forum does best, speculating on a basis of no fact.

They used to be red, but that tin of paint ran out in about 2002.

Might red be potentially confusing in locations where there are marker posts for the channel?

Even without channel markers red would be very wrong, it would still be a PHM.
