01
What SVC Marine Does at Drydock
SVC Marine provides drydock supervision in Vietnam for shipowners, vessel buyers and ship managers who need owner-side attendance during repair, class survey, coating, steel renewal, machinery repair and delivery close-out. We attend the vessel and the yard, control the repair scope, drive vendors and class items, verify progress with photo evidence, report cost and delay exposure, and close pending items before undocking or delivery.
SVC Marine attends the vessel and monitors the appointed repair scope at the yard. We track steel renewal, hot work, blasting and coating, machinery repair, variation orders and class deficiencies through to undocking readiness and delivery close-out.
02

- NDT / UTM follow-up
- Class item tracking
- Hot work permit visibility

- Pipe & tank items
- Test run / dock trial / sea trial
Vendor & Service Team Control
How We Attend a Drydock

03
Owner-Side Yard Attendance Process
SVC Marine attends the vessel and yard from pre-docking scope review through undocking and final report - with onsite progress checks and reporting to the owner.
- 01
Pre-docking scope review
We review the repair worklist from the execution side, flag unclear scope, missing materials and items that drive variation orders before docking.
- 02
Yard, vendor & class readiness check
We verify yard capacity, vendor mobilisation and class survey timing so the vessel does not arrive into an unready yard.
- 03
Arrival & docking attendance
We attend docking, block landing and initial inspection, recording vessel condition and opening the pending-item list.
- 04
Daily repair progress follow-up
We check the work on board and report completed, pending, delayed and owner-action items each day.
- 05
Steel / coating / machinery control
We follow steel renewal, blasting and coating standards, and machinery repair through inspection readiness and photo evidence.
- 06
Variation order & delay risk review
We check each VO against actual work, original scope and class comments, and report cost and off-hire exposure before approval where possible.
- 07
Class survey & pending item close-out
We track class survey items, surveyor comments and recommendations, and chase pending items toward close-out.
- 08
Undocking, sea trial & final report
We confirm undocking readiness, attend dock trial / sea trial where required, and issue the final owner report with delivery close-out.
04
Class Survey & Deficiency Close-out
Drydock work depends on class timing and survey comments. SVC Marine follows and reports class-related items on the owner's behalf - and drives deficiencies to close-out before undocking.
Class Survey Items Followed
- Hull inspection & structural comments
- Thickness measurement / UTM
- Sea valves, sea chest & underwater fittings
- Ballast & cargo tank inspection
- LSA / FFE service items
- Radio / GMDSS where applicable
- Machinery & safety survey items
Deficiency Close-out Execution
Final class, flag or statutory acceptance remains with the relevant class society, flag administration or competent authority. SVC Marine follows and reports class items on the owner's behalf and does not act as the class society.
- Deficiency list compiled from the vessel side
- Survey attendance & surveyor liaison
- Class recommendation tracking
- Rework identification before survey
- Evidence & close-out document collection
- Dock trial / sea trial attendance
- Final owner report & delivery close-out
05

Propeller & Stern Work - Vessel in Dock
Owner-side attendance on real drydock execution: propeller polishing, stern gear, hull and underwater work tracked and verified at the yard.
06
Cost, Delay & Variation Order Control
During drydock, the owner's risk is not only technical quality. Cost escalation, unclear variation orders, standby time, delayed class items, missing materials and poor sequencing all extend the vessel's off-hire period. SVC Marine tracks these from the vessel side and reports owner-side facts before they become commercial disputes.
Variation Order Review
Each VO checked against actual work, original scope and class comments before owner approval.
Manpower & Vendor Visibility
Daily observation of yard manpower, productivity and vendor attendance on the vessel.
Critical Path Tracking
The items that actually move undocking date - tracked and flagged before they slip.
Material Delay Monitoring
Owner-supplied and yard materials tracked so late delivery does not block the sequence.
Class Pending Item List
Live list of open class items and recommendations driven toward close-out.
Off-hire Exposure Reporting
Delay and cost exposure reported to the owner as decision-ready facts.

Frequently Asked Questions
What does a drydock supervisor do for the shipowner?
SVC Marine attends the vessel and yard on the owner's behalf - controlling repair scope, tracking class items, driving vendors, reviewing variation orders and reporting actual site facts daily. The owner sees what is really happening at the yard and can make timely technical and commercial decisions.
Does SVC Marine act as a shipyard?
No. SVC Marine is not a shipyard. SVC Marine represents the owner during drydock by attending the vessel and yard, controlling repair progress, tracking class items, checking vendors, reviewing VO exposure and reporting site facts to the owner or manager.
Can SVC Marine attend drydock on behalf of overseas owners?
Yes. SVC Marine attends the vessel and shipyard on behalf of overseas owners and managers, following repair progress, tracking pending items, reviewing class comments, verifying work evidence and reporting key issues throughout the docking period.
Does SVC Marine replace the class society?
No. SVC Marine follows and reports class-related items on the owner's behalf but does not act as the class society. SVC Marine acts on owner-side mandate - statutory class, flag and certification authority remains with the relevant class society and administration.
Can SVC Marine follow steel renewal and hot work?
Yes. SVC Marine controls crop-and-renew areas, insert plates, welding sequence, NDT/UTM follow-up, class-related steel comments and hot work permit visibility, with before-and-after photo evidence.
Can SVC Marine follow sandblasting and coating?
Yes. SVC Marine follows surface preparation, blasting standard, stripe coat, DFT checks, curing windows and weather/humidity risk that can block the coating schedule.
Can SVC Marine handle machinery and vendor follow-up?
Yes. SVC Marine controls main and auxiliary engine items, pumps, valves, compressors and auxiliary machinery, and drives service vendors - UTM, LSA/FFE, radio/GMDSS, diving, coating and workshop teams - from the owner's side.
Can SVC Marine help control variation orders?
Yes. SVC Marine reviews VO exposure by checking whether the item is linked to actual work, was in the original scope, is required by class comments, and affects the undocking schedule - and reports cost and off-hire exposure before approval where possible.
Does SVC Marine handle local agent formalities during drydock?
SVC Marine can attend to practical local formalities around the drydock - yard liaison, local service coordination and port-side attendance in Vietnam - as part of owner-side execution. Statutory port clearance, customs, immigration and flag formalities remain with the appointed local agent and competent authorities; SVC Marine does not replace the official ship's agent or any authority.
What information is required before drydock attendance?
Vessel name, IMO number, vessel type, expected yard or port, ETA, repair worklist, class status and due items, known deficiencies, required attendance period and reporting format. The more complete the information, the tighter the scope and cost control.
Can SVC Marine support post-purchase drydock after vessel acquisition?
Yes. Buyers of second-hand vessels often need drydock soon after delivery for class renewal, repair defects or trading readiness. SVC Marine executes buyer-side drydock planning and owner's representative attendance after vessel delivery.
