Ireland’s Largest Tug Initially Assists Cocaine Busted Bulker Bound for Bulgaria

18th July 2026
MV Matthew’s departure from Cork Harbour saw the powerful Irish-flagged tug Ocean Challenger play an important role as part of a complex towage operation. According to Revenue, an international shipping company has acquired MV Matthew for a nominal $1 with an agreement to tow the vessel to Varna in Bulgaria under a single voyage exemption by way of a dead-ship tow. This involves the tug Foreini Z, and it is expected the bulker is to be engaged in the Black Sea grain trade.

Following a technical issue with a tug, the cocaine-busted bulker MV Matthew finally left Cork Harbour yesterday, as Afloat reported, after a 24-hour-plus delay to its voyage bound for Bulgaria, writes Jehan Ashmore.

Assisting operations was Ocean Challenger, the largest Irish-flagged tug, which Afloat tracked from its Dinish Island base off Castletownbere. The powerful 62-tonne bollard pull (tbp) tug joined Cork-based tugs and an accompanying Greek-flagged tug, Foteine F, which also tracked from Aviles, northern Spain. It is assigned as the sole tug to tow the 28,647-tonne bulk carrier from the Port of Cork to the Black Sea port of Varna, where it is expected to arrive around the first week of August.

With minor repairs completed on a tug, it joined three more yesterday evening that assembled at Marino Point Jetty. The busy scene saw Atlantic Marine & Towage’s Ocean Challenger aid the MV Matthew amidships on the port side, while Doyle Shipping Group’s (DSG) green-hulled pair DGS Alex (55 tbp) was to starboard, and DGS Titan (77 tbp) managed astern with the bow handled by Foteine F, also involved in the complex towing procedure that began to head downriver.

The crew of Ocean Challenger has facilities comprising a galley, a mess room, an office, a laundry room, and a gym. As for accommodation, cabins are based on the configuration of 3 single cabins and 3 double cabins. The tug also forms Ireland’s largest fleet of tugs and workboats.

As for the 2001 built-in-China bulker, which had been previously named Honmon, it had lain idle at the jetty since September 2023 following Ireland's largest-ever cocaine interception of €157 million, which involved a daring Army Ranger Wing storming the vessel at sea by helicopter, with state agencies assisting, among them the Naval Service, with warning shots fired from LÉ William Butler Yeats (P63). The record-breaking drug interdiction off the Irish south coast led to eight criminals being prosecuted.  

Since MV Matthew’s seizure, arrest, and detainment in September 2023, it has cost the State (Revenue Commissioners), which have confirmed to be in the region of almost €17m through berthing fees, crewing, maintenance, and security coupled with surveys and legal fees.

Carrier's New Career

It transpires the Panama-flagged bulker carrier just shy of 190 m is not to be scrapped but sold to new shipowners and refurbished. However, the proceeds from the 25-year-old bulker will not generate sufficient funds to cover these expenses.

Its destination is Varna with an arrival delivery date of 9 August, Afloat understands, and it is to be used in the Black Sea grain trade.

Now that the bulker has finally vacated the centrally located Cork Harbour jetty, local residents will no longer be complaining of noise generated from the ship for almost the last three years.

As MV Matthew was towed downriver, it first passed the slipways used by the Cross River Ferries, and when off nearby Rushbrooke is Cork Dockyard, where owners Doyle Shipping Group (DSG) are notably reviving vessel building at the former V.C.D. shipyard, albeit in the form of small vehicle ferry on the short service crossing. 

When the sold MV Matthew entered the open sea off the entrance of Cork Harbour, an Afloat source says the bulker no longer required services from the Ocean Challenger, which then set off to its homeport in West Cork.

Cork Harbour Information

It’s one of the largest natural harbours in the world – and those living near Cork Harbour insist that it’s also one of the most interesting.

This was the last port of call for the most famous liner in history, the Titanic, but it has been transformed into a centre for the chemical and pharmaceutical industry.

The harbour has been a working port and a strategic defensive hub for centuries, and it has been one of Ireland's major employment hubs since the early 1900s. Traditional heavy industries have waned since the late 20th century, with the likes of the closure of Irish Steel in Haulbowline and shipbuilding at Verolme. It still has major and strategic significance in energy generation, shipping and refining.

Giraffe wander along its shores, from which tens of thousands of men and women left Ireland, most of them never to return. The harbour is home to the oldest yacht club in the world, and to the Irish Navy. 

This deep waterway has also become a vital cog in the Irish economy.

‘Afloat.ie's Cork Harbour page’ is not a history page, nor is it a news focus. It’s simply an exploration of this famous waterway, its colour and its characters.

Cork Harbour Festival

Ocean to City – An Rás Mór and Cork Harbour Open Day formerly existed as two popular one-day events located at different points on Cork’s annual maritime calendar. Both event committees recognised the synergy between the two events and began to work together and share resources. In 2015, Cork Harbour Festival was launched. The festival was shaped on the open day principle, with Ocean to City – An Ras Mór as the flagship event.

Now in its sixth year, the festival has grown from strength to strength. Although the physical 2020 festival was cancelled due to Covid-19, the event normally features nine festival days starting on the first week of June. It is packed full of events; all made possible through collaboration with over 50 different event partners in Cork City, as well as 15 towns and villages along Cork Harbour. The programme grows year by year and highlights Ireland’s rich maritime heritage and culture as well as water and shore-based activities, with Ocean to City – An Rás Mór at the heart of the festival.

Taking place at the centre of Ireland’s maritime paradise, and at the gateway to Ireland’s Ancient East and the Wild Atlantic Way, Cork is perfectly positioned to deliver the largest and most engaging harbour festival in Ireland.

The Cork Harbour Festival Committee includes representatives from Cork City Council, Cork County Council, Port of Cork, UCC MaREI, RCYC, Cobh & Harbour Chamber and Meitheal Mara.
