180DAYS
Ocean Guardian has entered the D-180 drydock window
Class due date February 2027 (Special Survey + docking). The Chief has already drafted scope, schedule and a preliminary budget: it is waiting for your approval.

How the agent built this scope
1 Read the class due date in the registry and opened the project at D-180
2 Crossed PMS routines coming due with the history of the last 2 drydocks
3 Pulled crew-reported corrective items that require the dock
4 Ordered everything by precedence and built the 18-day critical path
5 Priced each item from fleet history and previous quotes

Drydock · Financial & cash
Drydock cash flow
Projected monthly spend · 2027 and 2028 · illustrative figures
2027 concentrates 3 drydocks while 2028 has only 1.
Ocean Titan's class window allows docking as late as Feb 2028 without touching the due date (36 months from her last docking), and she is deployed on charter in the Western Pacific until Q4 2027. Moving her drydock from Nov 2027 to Feb 2028 relieves $2.3M of 2027 cash, satisfies the one-docking-per-half-year constraint and keeps class compliance at 100%.

Rules the agent respected
✓ Class window: no docking beyond the 36-month limit (ABS/IACS)
✓ Operational rule: at most 1 drydock per half-year
✓ Charter commitments: no docking during a committed deployment
✓ Cash: half-year peak below the ceiling set by Finance

Conflict detected: 2 drydocks in H2 2027
Ocean Lee (Aug 2027, class due) and Ocean Titan (Nov 2027, planned) violate the one-docking-per-half-year rule and the half-year cash ceiling ($4.05M > $2.5M). Titan is also still deployed in the Western Pacific. The agent evaluated 6 valid combinations and highlighted the best 2:
Option A · move Ocean Titan to Feb 2028
- Class window respected (limit: Feb 2028; Special Survey due Apr 2028)
- One drydock per half-year across the whole plan
- 2027 cash relieved by $2.3M; half-year peak drops 43%
- Returns from the Pacific deployment with no early demobilization
Option B · keep Nov 2027 and relax the rule
- Requires leadership approval for 2 drydocks in the half-year
- $2.3M of additional cash concentrated in 2027
- Early demobilization from the Pacific charter (penalty exposure)
- No class benefit: the due date remains Apr 2028
How the engine decides
On every change (a new corrective item, a vendor delay, a window update), the agent re-evaluates the entire fleet plan: each vessel's class window, cash per half-year, yard slot availability and charter commitments. If every rule passes, the plan stands. If one breaks, it presents alternatives ranked by total cost, including the off-hire cost of $38k/day per vessel out of service. The final call is always human.

Specialist clash detected
The OEM-certified thruster engineer (the only one qualified for the overhaul) is booked on Ocean Guardian Oct 23 to Nov 1 and also on Ocean Valor's drydock planned for May 2027. No clash in this cycle, but the agent has already blocked his calendar for both windows and will alert you if either docking moves.

Fleet view: if Ocean Valor docks in the same window next spring, the same paint and steel crew covers both projects, with an estimated $34k saved in mobilization.
How the agent staffs the dock
1 Reads the approved scope and flags items that require certification (thrusters, welding, NDT)
2 Checks who in-house is qualified and who must come from outside (OEM, contractor)
3 Schedules each professional for the day their task starts, not day one
4 Cross-checks clashes with the fleet's other drydocks over the next 18 months
5 Prices flights, lodging and per diems into the drydock budget

Equipment
What became a drydock item
Trigger rule
Every piece of equipment carries a manufacturer service interval (in running hours) and a drydock flag: items that can only be done out of the water enter the scope automatically when the hour projection lands inside the dock window. Past 85% of the interval, the agent flags it; past 100%, the item becomes mandatory and moves to the top of the priority list.
