This is political and may not be suitable for this site.
Some issues have already been mentioned above, but we will give points as to why this absolute national industrial gem has a case and is so important to the local area and nationwide.
1. Here at Pallion, an already exsiting facility and it's older sister Harland and Wolff at Appledore is a great facility though it is far smaller, less capable but is the only comparable facility. Babcock at Rosyth is building a similar assembly hall but with no integrated under cover dry dock, it is a load out shipbuilding/factory facility in which the final product is loaded out onto a barge or floating dry dock. Portsmouth ship factory has been lost and was similar to the new Babcok facility. Both Babcock and VT's are not strictly ship factories as in the single building that Pallion is. Only the New Scotstoun facility if built, will compare to New Pallion and even this potentially superb facility would have it's dry dock separate from the other steel production facilities at Scotstoun.
2. Excuses used. Asbestos present yet asbestos walls have been removed and other facilities have or had asbestos and many are older too. Pallion is not an old facility.
2a. Business rates. If allowed to do what it was designed to do, with other services to offer, can far outweigh the damaging unfair business rates that have led to much decline in industries. When down turn comes many are demolished which is enforced decline and usually what replaces it is a far less important development. When the market returns the UK loses the opportunity to capitalise on . The rates are paid for by the rentees as shown in the Dunlop property website.
2b. Upkeep. As the landlord has enjoyed companies renting the facility and must have made money from this arrangement, no real maintenance by the landlord looks to have been made and possibly, it has been in their interest to allow the run down of such an important facility, for short term future profits, as in redevelopment which is a classic practice taken to build houses on. The question must be, what did The present owner pay for New Pallion? Would it be the equivalent cost/price to build in the 1970s or the possible cost in today's prices which judging by the new Scotstoun facility some years ago could well be around 200 million pounds or even more to create. Not all blamed be targetted at the present owners. They have faced certain interests that want The Wear to take a pre 2007 direction, so different to the Tyne, Tees, Blyth and the Humber.
The fact BAE has not yet gone ahead with the New Scotstoun ship factory even with 8 Type 26 frigates to build and the vast profits from this contract say much. The 9.87 billion pounds (2017 prices) yet no investment in such a New Pallion like facility. The slow down in production of the Type 26 ship does not help, but the main reason was the reduced number of Type 26 ships.
2c. Dredging.
The river Wear being dredged will have to he addressed at some point in time. The river in areas is a disgusting disgrace to the City and a sad indictment to the powers that be. It is also very ungreen to a Council that plays on it's green credentials! But! Could the dredging provide a resource than just a waste? Could the value mitigate some of the costs in dredging? An example is the material being dredged from the channel of the Ardesier facility. Any dredged material has a use and value. The dredging problem is purely smoke and mirrors and a red herring excuse by certain interests.
3. Wealth creation.
Labour, land and capital. This area has brought wealth making industry to people and the city in the past years. Wealth in which products were made services given etc. Money goes into workers pockets and companies invest. Any future development is likely to be a wealth extracter in which after a short term development has been built, wealth will be extracted from people
as in Bills from council tax, water rates, gas and electricity costs, if a housing development were built. That is not including rent or mortgage for hugely over priced dwellings which we hear about some being affordable homes which must mean most are unaffordable and shows the total dysfunctional housing sector which is completely rigged for the developer who is really just a land dealer.
The thirty acreas that the present owner gained for a fraction of the price compared to what it cost to be redeveloped into a state of the art shipbuilding facilitg. How much more after the hope value gained after planning permissions. In the south, planning permission can give a one acrea agricultural piece of land up to 250 to 300 times upside this making house ownership unaffordablea it can take up to 15 times peoples salaries, which is totally unacceptable, a scam and would not be accepted in any other sector. No one goes to the only 5% affordable new cars section of a dealership.
Any learning and historical centre will not create wealth of a maritime contract. Manufacturing produces a real tangible product and the area makes and puts money into people's pockets and in many cases, stop tax payers money going abroad with contracts lost abroad. A huge amount of learning is done in working marine facility anyhow and the facility still has story that is on going and history to make!
4 New Pallion ship factory is a facility that lends itself to improving/increasing productivity.
5. Being green.
Overrall emissions, population and per capita.
China, Spain, South Korea Germany and Japan. Not having the Pallion facility could well (most likely) lead to services and products coming from Countries that are dirtier and which actually mean the UK is helping to more emissions, not less.
6. Capacity in facilities and people is mentioned in this article yet Pallion and a local skill set exists.

Median wage rate in Sunderland compared to the national median average.
8.
Is a modern dredger for the North East rivers but obviously looking at the Wearside needed? Should be noted that Hi-Spec digger buckets manufactured at Pallion are for (ironically) certain types of dredging.
9. New Pallion is a security and extra capacity asset to partner MoD and any UK taxpayer funded projects. Obvious ones being the Fleet Solid Support Ships the future Type 83 Destroyer and ships required for coastal services etc... The obvious renewable sector goes without saying. Pallion is national asset for the UK marine industry as a whole and anything that was put in it's place will come no where near it in importance and cost.
10.
Pallion is privately owned.
But Pallion is of national and political significance and importance. The owners are the guardian's of this facility and have a moral duty to protect it.
11.
Where is the business plan from the various interests who want to demolish this one off facility?
12.
The New Pallion marine facility has still not fulfilled it's potential.I
13.
There was only a moratorium on shipbuilding. That has been over for many years.
