OPPOSITION parties have united in condemnation over ministers' rejection of the "catastrophic failure" conclusion of an inquiry into the procurement of two lifeline Scots ferries which have hampered by soaring costs and up to five years of delay.

Scottish Labour’s transport spokesman Colin Smyth said: “Heads should roll over this shambles.

Connectivity and islands secretary Paul Wheelhouse hit back at the results of an extensive investigation by Holyrood's rural economy and connectivity committee insisting the government took "balanced, informed decisions following appropriate diligence and independent advice" and that securing hundreds of skilled jobs cannot represent failure.

Ferguson Marine's financial collapse in August, 2019 led to a state takeover, while the delivery of two lifeline island ferries MV Glen Sannox and Hull 802 which were due online in the first half of 2018 will be between four and five years late.

The owners of the last civilian Clyde shipyard went into administration following a dispute with Caledonian Maritime Assets Ltd - the taxpayer-funded company which buys and leases publicly owned CalMac's ships on behalf of the Scottish government - as the price of the construction of the ferries under a £97m fixed price contract more than doubled.

Around £45m in Scottish Government loans to keep the yard afloat have also been written off.

In their 129-page report, MSPs called for a “root-and-branch overhaul” of the ferry procurement process, declaring that established procedures are “no longer fit for purpose”

The report in December said the Scottish Government was too willing to press ahead with the ferry project despite the risks involved and stated CMAL and Transport Scotland’s due diligence was “inadequate”.

It also found “strong evidence” to suggest Ferguson Marine continued to build the ships incorrectly to ensure it would receive “milestone payments” that CMAL was legally obliged to give it after completion of certain stages of the project.

But Mr Wheelhouse has hit back saying: "While there are lessons to be learned, which we have acknowledged, we do not accept the Committee’s description of a 'catastrophic failure'.

"In the face of contractor non-performance at the yard in relation to 801 and 802, the Scottish Ministers took action to secure the future delivery of the vessels to serve the island communities which rely upon them, to secure the employment associated with continuation of those vessel contracts, and to secure the future of the yard in Inverclyde.

Scottish Ministers took balanced, informed decisions following appropriate diligence and independent advice. In reluctantly accepting increased cost and timescale for the delivery of the vessels, Scottish Ministers have acted and have secured hundreds of skilled jobs and wider economic activity. I do not regard those difficult decisions to represent a failure."

HeraldScotland:

Speaking about the two boats, the minister insisted: “I am satisfied that procurements in relation to 801 and 802 were undertaken fastidiously, in good faith and following appropriate due diligence.”

He said the CMAL was “already introducing improvements to its own processes” – but stressed that “these improvements should not be viewed as criticism of the process adopted in relation to 801 and 802, but build upon best practice exhibited in other areas”.

Mr Wheelhouse set out the Scottish Government’s view, that “contractor failure has been a very significant factor in the difficulties we have seen arise”.

And he said there was “disappointment” from ministers that the report did not “better reflect the contribution of the contractor’s non-performance, contract management and financial management” in relation to the problems experienced with the construction of the ferries.

But the response has been treated with disdain by all the major opposition parties.

Mr Smyth said: “The handling of the botched ferry construction was righty described as catastrophic by the cross-party committee. The failure of the SNP Government to accept any responsibility or even acknowledge the scale of failure shows the arrogance of a government in utter denial.

“Taxpayers are being forced to foot a bill that has doubled and our island communities are being made to wait years for delivery of these ferries, yet we have not had a single word of apology from SNP Ministers for their lack of intervention when they knew this contract was failing.

“Heads should roll over this shambles but, instead, we have a dismissive attempt by Ministers to brush this scandal under the carpet, showing contempt for taxpayers and the communities still without these lifeline ferries.”

Conservative infrastructure spokesman Graham Simpson said: “The SNP are in total denial over their ferries fiasco. The minister responsible is effectively saying that there is nothing to see here and that nothing has gone wrong.

“The cost of these two ferries has spiralled out of control and they are still not even built yet, which has been a disgraceful failure for the communities which rely on them.

“It is yet another prime example of the SNP splashing the cash but failing to deliver the infrastructure on the ground.”

Sottish Liberal Democrat rural economy and connectivity committee member Mike Rumbles said the ministers' response failed to address the millions of pounds of losses faced by the taxpayer and indicates that the government remains "fully supportive of our transport agency Transport Scotland, CMAL, and Calmac" despite the report heavily criticising all three bodies.

Mr Rumbles said: "This is an appalling government response to the committee's unanimous report. The failure to accept that there was a catastrophic failure in the procurement process suggests ministers have their hands over their eyes and their fingers in their ears.

"Meanwhile the government's response criticising the committee’s report for not blaming the contractor enough, suggests that complacency is well entrenched in the Scottish government, with an almost complete lack of understanding of the reality of their mistakes from the start to the finish of this sad episode.

"To top it off the Scottish government does not even mention in their response the millions of pounds lost to the taxpayer. This is the worst government response to a committee report I have ever seen. The minister must immediately appear before the committee to answer for this dereliction of duty."
