DSM AMBITION (IMO 9472672) detained at Shanghai, October 2026
The 18-year-old Panama-flagged general cargo ship DSM Ambition has been detained in Shanghai on 6 October 2026, the third detention recorded against the vessel in just eight months. The vessel changed ownership, management, flag, and name in August 2026, and her deteriorating PSC record under these new operators marks a sharp departure from more than a decade of detention-free service.

Request accessThe detention
DSM Ambition was detained in Shanghai on 6 October 2026 by Chinese port state control authorities operating under the Tokyo MoU. The recognised organisation is Nippon Kaiji Kyokai (ClassNK) and the listed ISM company is Union Sky Corp Limited. The number of deficiencies cited has not yet been published. At the time of the report, the vessel was at anchor on the China coast with an AIS destination of Kuantan, Malaysia, and an ETA of 15 October.
The vessel
DSM Ambition is a 7,727 GT, 9,049 DWT general cargo ship built in 2008 by Kanasashi Heavy Industries in Shimizu, Japan. She measures 104.83 metres LOA with a beam of 20 metres and a current draught of 8 metres. The vessel is Panama-flagged and classed with Nippon Kaiji Kyokai (ClassNK), which has maintained classification since delivery. She was originally named King Fisher at delivery, became Westwind Bliss in May 2014, and was renamed DSM Ambition in August 2026. She previously flew the Philippine flag from 2014 until returning to Panama registry in August 2026.
Inspection history
The vessel has accumulated 54 PSC inspections since May 2008, all under the Tokyo MoU, with 94 deficiencies recorded for an average rate of 1.7 per inspection. Two prior detentions appear in the record, both in 2026: an initial inspection in Busan on 23 February 2026 that found six deficiencies and resulted in detention, and an initial inspection in Shanghai on 16 August 2026, also with six deficiencies and a detention. A follow-up inspection in Shanghai on 18 August cleared that detention with zero deficiencies. The current detention on 6 October marks the third in roughly eight months. What makes this record striking is the contrast with the vessel's earlier history. From delivery in 2008 through the end of 2025, across approximately 48 inspections spanning 17 years, the vessel was never detained. Deficiency counts during that period were modest: a spike of 10 deficiencies at Wakamatsu in September 2023, and another 10 at Kobe in October 2013, but no detention in either case. Inspections in Japan regularly returned zero deficiencies. The breakdown began in 2026. The Busan detention in February came while the vessel was still under the previous management of Baliwag Navigation Inc. Following the ownership and management change in August, Shanghai PSC detained the ship within 12 days, and now again in October. The deficiency count at recent initial inspections, consistently six, is notably higher than the vessel's long-term norm.
Ownership and management
The vessel underwent a complete change of ownership and management in August 2026. The registered owner is now DS Ambition Shipping Co Ltd, sharing an address in Chai Wan, Hong Kong, with the ship and commercial manager Vina Bridge Shipping Co Ltd; both took their roles on 4 August 2026. ISM management passed to Union Sky Corp Ltd, a Hong Kong-based company operating a fleet of just two vessels, effective 7 August 2026. Prior to this, the vessel had been managed and ISM-managed by Baliwag Navigation Inc of the Philippines since May 2014, with registered ownership held by Blissful Maritime Investments. Before Baliwag, the vessel was managed by P&F Marine Co Ltd from late 2008, and at delivery by Wako Kaiun YK under the ownership of Ibis Maritime SA. The August 2026 transaction therefore ended a 12-year period of stable management under Baliwag and brought in an entirely new ownership chain with no prior track record visible in this vessel's history. The simultaneous changes to name, flag, owner, and both managers are consistent with a sale and change of beneficial ownership.
Risk profile
VesselScore rates DSM Ambition at 44.5 out of 100, placing her in the "very high risk" calibration band with an observed detention probability of 11.6%. The two heaviest contributors are the detention component (c2), which scores the maximum 20 out of 20 points reflecting the two recent detentions already in the system, and the age baseline (c6), also at maximum with 10 out of 10 points for an 18-year-old vessel. The deficiency rate component (c1) adds 13.2 out of 15 points. The flag and class combination contributes 6 out of 10 points, reflecting the Panama flag's mid-tier standing in the Tokyo MoU targeting matrix. AIS behaviour scores 3 out of 5 points, with three loitering events recorded and no AIS gaps. No sanctions or casualty flags are present. Manager churn, despite the recent wholesale change, scores zero; this component does not appear to have captured the August transition in its current calculation.
What to watch
The vessel is currently at anchor at Shanghai awaiting release. Given that three detentions in eight months will place DSM Ambition in the highest-priority target category for any Tokyo MoU port she calls at next, the planned voyage to Kuantan should be monitored closely. Under Tokyo MoU rules, a vessel with multiple detentions in the rolling 36-month window faces an expanded inspection regime and potential refusal of access if a further detention occurs. Charterers and underwriters should verify that Union Sky Corp Ltd and Vina Bridge Shipping have established adequate safety management systems and that all outstanding conditions of class and statutory certificates are current. The ISM manager's fleet of only two vessels offers limited benchmarking data on operational standards.
