Independent engineering oversight for new build, refit and survey.
T6 Marine provides independent owners' representation, engineering support and project management for superyacht new builds, refits and marine surveys. From specification through to delivery, we protect the owner's interests with clear technical advice, practical project oversight and impartial decision-making.

An engineer's eye, working entirely in your interest.
T6 Marine operates without shipyard retainers or supplier commissions, ensuring all technical assessments, recommendations and project decisions are made solely in accordance with the owner's operational, commercial and compliance objectives.
Understand the brief
Recommendations are developed only after on-board inspection, review of the vessel's technical history, assessment of maintenance records and verification of operational condition.
Set the technical baseline
Scope definition, applicable standards and class requirements are established at project outset, providing a controlled technical baseline against which contractor performance, deliverables and compliance can be objectively assessed.
Manage the work
Regular presence with the yard or contractor, tracking progress, cost and quality against the plan.
Sign off with confidence
Commissioning, sea trials and handover are verified in person before anything is accepted.
Two and a half decades across sea and shipyard.
Our approach is shaped by time spent both running engineering departments at sea and managing projects dockside — a rare combination that means we know what a yard promises and what a vessel actually needs.
- 3rd Engineer, British Flagged Commercial Fleet — auxiliary machinery maintenance
- 2nd Engineer, 90m Super Yacht — routine maintenance & ISM routines
- Chief Engineer, 90m Super Yacht — engineering department, contractors & class liaison
- Shipyard project teams — new build & refit delivery
Eun Dunbar
Eun established T6 Marine following 26 years of continuous sea-going and shipyard-based engineering experience, most recently as Chief Engineer with technical authority for the engineering department of a 90m superyacht. The role required direct interface with OEMs, specialist contractors and Lloyd's Register to maintain class compliance, machinery reliability and vessel operational readiness.
This combination of senior engine-room command and shipyard project delivery underpins T6 Marine's approach to new builds, refits and surveys: technically informed decision-making, practical yard interface management and owner-focused assurance from specification through to acceptance.
