The heavy deck carrier KING ONE has entered technical management with Synergy Marine Group, adding a specialised vessel designed to support offshore wind logistics.
Constructed by Dajin Penglai Shipyard for Dajin Offshore, KING ONE is a 40,000 DWT deck carrier and the first in a new class developed to transport large offshore wind components.
These include monopile foundations for 15 to 25 MW turbines, jacket-type and floating foundations, and other large offshore modules.
At 240 metres in length and 51 metres in breadth, with a deck area of approximately 12,000 square metres, the vessel is designed for cargoes of a scale and profile not commonly handled by conventional vessels. This design supports the increasing size and complexity of offshore wind installations, where logistics capability plays a critical role in project execution.
Maiden Voyage from China to Tees Port
KING ONE recently completed her maiden voyage, covering nearly 12,000 nautical miles from Penglai, China to Tees Port in the United Kingdom. The vessel transported eight XXL monopiles, each approximately 10 metres in diameter and weighing over 1,200 tonnes, for a major offshore wind development.
This voyage highlights the operational demands associated with transporting large offshore structures across long distances, including planning, cargo handling and coordination between multiple stakeholders.

Ship Management for Heavy Deck Carriers
Heavy deck carriers operate within a specialised segment of maritime transport. Each voyage requires detailed deck load planning, stability assessment and engineered sea-fastening arrangements tailored to the cargo’s geometry and weight distribution.
Offshore wind cargoes require close coordination between shipboard teams, technical managers and project stakeholders from loading through to discharge. These operations demand precision, consistency and strong technical oversight.
Under Synergy Marine Group’s technical management, KING ONE is supported across:
- Planned maintenance and asset reliability
- Crew management and onboard readiness
- Regulatory compliance and safety management
- Operational oversight and voyage support
This approach ensures that specialised vessels such as KING ONE are managed with a focus on safety, performance and lifecycle integrity.
Supporting the Offshore Energy Transition
As offshore wind projects continue to expand in scale, the need for specialised transport solutions is increasing. Vessels designed for large structural components play an important role in enabling these projects, connecting fabrication yards with installation sites across global markets.
KING ONE represents a step forward in this segment, combining vessel design, cargo capability and operational management to support the evolving requirements of offshore energy logistics.
