New restrictions on the transportation of dangerous goods (DGs) could be a future problem for ferry capacity, an Argyll Councillor has warned.
Under new Maritime and Coastguard Agency (MCA) rules, DGs, including diesel, petrol, butane and propane, cannot be transported on CalMac’s new vessels when they are at full capacity.
Instead, the passenger numbers are restricted to whichever is greater out of 25 or one passenger per three metres of ferry.
Both recently delivered ferries, the MV Glen Sannox, serving Arran, and MV Isle of Islay, serving Islay, are the only in service vessels affected by the rule.
Old vessels in the fleet are not affected by the rule change.
Fuels such as these are essential for island life, and when they are delivered on these new vessels, they essentially cancel an entire sailing.
Councillor Alastair Redman worries that this poses a future crisis for CalMac’s capacity.
He submitted an FOI (Freedom of Information Request) to CalMac which confirmed his fears that the MV Isle of Islay would be affected by these new rules.
Redman said: "Our island communities rely on ferries not as a luxury, but as a lifeline. The idea that a brand-new vessel could actually reduce flexibility and capacity when carrying essential goods such as petrol, diesel, paraffin oil, heating fuels and Calor gas is deeply concerning.
"We are effectively being asked to accept a step backwards. That cannot be right.
"This creates a two-tier system where the level of service depends entirely on which vessel turns up. That is no way to run a reliable and resilient ferry network.”
He added: "This is not just a technical issue—it has real consequences for people and businesses across our communities. Farmers, crofters, fishermen and tradesmen all depend on the reliable movement of fuel, gas, and essential materials.
"Restricting the transport of key supplies places additional strain on already fragile supply chains and will inevitably drive up costs locally.”
This summer, just 0.3 per cent of sailings will be affected. But what happens, he says, when all the old guard are replaced?
“As more of the older vessels are retired, there is a real danger that these restrictions become the standard across the fleet. If that happens, it will create serious and ongoing problems for island communities," Redman said.
This is a problem looming decades down the line, but for now, CalMac says it is exploring its options to reduce disruption.
The Oban Times approached CalMac and the MCA for clarification on why the new rules were in place and whether or not they would affect all new ferries.
The MCA said that the limits imposed on these vessels were assessed in accordance with the International Maritime Dangerous Goods (IMDG) Code.
It also added that the exceptions granted to previous vessels to do mean a precedent is in place. The MCA is simply tightening its enforcement of existing rules in line with IMDG code updates.
A CalMac spokeswoman said: “To protect customers, crew, and the environment, the carriage of dangerous goods (DGs) on vessels is governed by strict international regulations.
"Until recently, for certain goods, the Maritime and Coastguard Agency (MCA) granted exemptions to these rules, but it has advised that these exemptions will not apply to newly built vessels.
"On the Islay route, there are two affected customers, and we are working directly with them to manage their bookings. MV Finlaggan can continue carrying these types of goods under her existing exemption, and we will review our approach ahead of MV Loch Indaal entering service.
“Looking ahead, we are exploring how best to manage the shipping of DGs while continuing to provide the capacity and frequency of service required on each route. We will continue to develop options in close collaboration with local communities and customers.”
