CELTIC MARINER (IMO 9377925) detained at Drogheda, October 2026
The 2010-built general cargo ship Celtic Mariner has been detained in the Irish port of Drogheda, marking her third detention in a 16-year operational life and the first under new UK-based owners Charles M Willie & Co, who took over the vessel just seven months ago. The detention comes after a wholesale change of ownership, management, flag, and name in March 2025, a transition that the vessel's risk score had already flagged as a concern.

Request accessThe detention
Celtic Mariner was detained at Drogheda, Ireland on 1 October 2026. No detail on the number or nature of deficiencies, the recognised organisation, or the ISM company has been published in the THETIS listing at this stage. The vessel was flagged as Portuguese and classified as a general cargo ship. She was moored at the time of the report, with AIS showing her position in the North East Atlantic as recently as two hours prior to the data pull.
The vessel
Celtic Mariner is a 2,967 GT, 4,927 DWT general cargo ship built in 2010 at the Chowgule yard in Goa, India. She measures 89.94 metres LOA with a beam of 14.43 metres and an air draft of 22.5 metres. She is gearless, single-hold (205 cubic metres capacity recorded), powered by a Daihatsu 6M25 four-stroke diesel engine driving a controllable pitch propeller, with a service speed of 11.5 knots and a 250 kW bow thruster. She is classed with DNV, which has maintained her classification since delivery. The vessel was originally named Amisia, renamed Meerdijk in May 2010, and took her current name Celtic Mariner in March 2025 when she reflagged from the Netherlands to Portugal (Madeira international register). At 16 years old she is firmly mid-life for the segment, though the age component of her risk score is at its maximum penalty, reflecting the elevated baseline detention risk of vessels in this age bracket.
Inspection history
The PSC record comprises 29 inspections across three MoUs (20 Paris, 7 Mediterranean, 2 Black Sea) between August 2010 and April 2025, yielding 89 deficiencies for an average rate of 3.1 per inspection. Before the current detention, the vessel had been detained twice: once at Fos-sur-Mer in May 2014 with just two deficiencies, and once at Ghent in November 2020 with 15 deficiencies spanning 11 categories, including an inoperative emergency generator, ISM-related failures, fire safety defects, and hatch cover issues. The Ghent detention was a serious event and occurred under the previous manager SCG Management BV. After the Ghent detention the vessel's record improved markedly. Inspections at Corigliano Calabro (June 2021, six deficiencies), Kocaeli (February 2022, three), Rouen (June 2022, zero), Poti (October 2022, four), Tom Roes Point (April 2023, four), and Liverpool (April 2024, four) all passed without detention. The most recent inspection at Saint-Malo in April 2025, the first under the Willie management, recorded a single deficiency related to the MLC Declaration of Maritime Labour Compliance Part I. That finding is notable: the vessel's Maritime Labour Certificate, reissued in April 2025, carries a short-term expiry of 4 October 2025, consistent with a provisional certificate issued during a change of management. Ireland has featured repeatedly in the inspection history. Previous inspections at Tom Roes Point (2019, 2023) and Foynes (2012) all passed without detention, making this Drogheda detention the vessel's first in Irish waters.
Ownership and management
Celtic Mariner has been through three distinct management regimes. She was delivered in 2010 under Navigia Shipmanagement BV (ISM) and Shipcom Bereederungs GmbH (commercial manager), both based in the Netherlands/Germany. In July 2017, she transferred to SCG Management BV as ship manager and ISM manager, with registered ownership moving to Meerdijk 2.0 BV, both Dutch entities. The vessel's two prior detentions occurred across these first two management periods. In March 2025, a wholesale change took place. Charles M Willie & Co Shipping of Cardiff assumed all three roles: registered owner, ship manager/commercial manager, and ISM manager. The vessel simultaneously reflagged from the Netherlands to Portugal and was renamed from Meerdijk to Celtic Mariner. Willie is a well-known family-run short-sea operator with a fleet of around 15 vessels. The breadth of the March 2025 change, affecting ownership, management, flag, name, and certificates simultaneously, is significant. While it is not unusual for an acquisition to trigger a full transition, the VesselScore model penalises this level of churn heavily, and for good reason: vessels in transition are statistically more likely to present operational gaps.
Risk profile
The VesselScore at the time of the detention was 59.4 out of 100, placing Celtic Mariner in the "above average risk" calibration band with a modelled detention probability of 4.26%. The score was driven primarily by three components. Manager churn (C4) scored the maximum 10 out of 15 penalty points, reflecting the complete ownership and management change in March 2025. The age baseline (C6) also hit its ceiling at 10 out of 10, a standard penalty for a 16-year-old general cargo vessel. Severity mix (C3) contributed 10 out of 10 penalty points, indicating that the types of deficiencies recorded, including ISM and emergency systems failures from the Ghent detention, remain in the scoring window. On the positive side, the recent detention component (C2) scored zero penalty points, as the 2020 Ghent detention had aged out of the rolling window. The deficiency rate (C1) contributed only 5.6 of 15 possible penalty points, reflecting the moderate post-2020 improvement. Flag and class (C5) added just 2 of 10, consistent with a Portuguese flag under DNV class. AIS behaviour (C9) added 3 of 5 points, noting three loitering events and no dark gaps. Sanctions and casualty screens were both clear. The overall picture is a vessel whose fundamentals are respectable but whose transition risk was clearly elevated. The model correctly identified this vessel as above average risk before the detention materialised.
What to watch
Several items warrant monitoring. First, the release conditions and deficiency details from Drogheda, which have not yet been published. Second, the Maritime Labour Certificate and Safety Management Certificate both carried provisional expiry dates of 4 October 2025, meaning they should have been reissued by now; any lapse or delay could be a factor. Third, this is the vessel's first detention under Willie management and the first significant test of their operational transition. The quality and speed of rectification will be telling. Finally, as this detention falls within the Paris MoU region and follows the March 2025 management change, the vessel's targeting profile will be elevated for subsequent port state calls across Europe. Charterers should request confirmation of release and a copy of the rectification action report before fixing.
