"The leaking unit is probably the 2022 starboard 316L manifold — but the call did not confirm it."
Source documents
svc_call / call_intake.mdthe call
Caller was not certain which hull or which genset. Said "the newer one" then corrected to "the one from a few years back." Equipment identity is not confirmed from the call alone. Caller did not have a serial number or a Riverbend job number.
harborline_records / ticket_2024_0677.mdopen finding, same symptom
This is an open issue on the 2022 starboard unit (RMW-CM-22-0233). The 2026 service call describing weeping on a Riverbend manifold may be a continuation of this unresolved 2024 finding.
Why "probably," not "confirmed": The system connects the 2026 symptom to the 2024 open finding on the same unit — that's the strongest available signal. But it's an inference from symptom-match, not a confirmation. The brief says "probably" and routes identity confirmation to the dispatch checklist.
"Two Riverbend records disagree on the 2019 unit's install date — five weeks apart, unreconciled."

harborline_records / equipment_2019.mdequipment record · 2019-03-18
Install date on this record: 2019-03-18. The install date on this equipment record does not match the install date on install record HMS-INST-2019-04 (2019-04-22). The discrepancy has not been reconciled. Do not treat either date as confirmed.
harborline_records / install_2019.mdinstall record · 2019-04-22
Install date: 2019-04-22. Riverbend job reference RMW-2019-0331. Equipment: coolant manifold assembly, 304L stainless, serial RMW-CM-19-0114.
Why this is the centerpiece: Two Riverbend documents, same unit, dates five weeks apart. The system surfaces the conflict rather than picking the more convenient date — and notes that warranty math depends on resolving it. In this case, both dates land the unit out of warranty anyway (see the warranty claim), so the conflict does not change the outcome here — but the brief still refuses to paper over it.
"The 2024 service finding on the starboard unit is still open — no resolution record on file."
Source documents
harborline_records / ticket_2024_0677.mdservice ticket · open
Resolution: OPEN — no resolution record on file. Technician recommended a follow-up grommet replacement visit. No follow-up ticket was created and no resolution record was filed. This service event was left open.
harborline_records / equipment_2022.mdequipment record
One open service issue: HMS-SVC-2024-0677, an unresolved early-grommet-seep finding at outlet 7. No resolution record on file. Recommended grommet replacement was never scheduled.
Why this is flagged open: Two documents independently record the 2024 finding as unresolved. The brief does not treat the issue as closed just because time has passed — an open finding with no resolution stays open until a resolution record says otherwise.
"Harborline reports intermittent coolant weeping at a branch outlet; the caller could not identify the unit."
Source documents
svc_call / call_intake.mdthe call
Caller reports intermittent coolant weeping at one of the branch outlet fittings on a Riverbend-built coolant manifold. Says it "started a few weeks ago, getting worse." Caller was not certain which hull or which genset. Caller did not have a serial number or a Riverbend job number.
Why this is the starting point: The brief records the call as it was received — symptom, timing, and the gap. The equipment-identity gap is not a flaw in the brief; it's a fact about the call, carried forward honestly rather than guessed away.
"Riverbend has two manifolds at this customer: a 2019 304L port unit and a 2022 316L starboard unit."
Source documents
harborline_records / install_2019.mdthe 2019 unit
Equipment: coolant manifold assembly, 304L stainless, serial RMW-CM-19-0114. Installed on Harborline support vessel "Tidewatch" — port main genset. 8 branch outlets, 1.5" OD branch tube.
harborline_records / install_2022.mdthe 2022 unit
Equipment: coolant manifold assembly, 316L stainless, serial RMW-CM-22-0233. Installed on Harborline support vessel "Tidewatch" — starboard main genset. 10 branch outlets, 1.25" OD branch tube.
harborline_records / account_note.mdaccount consolidation
Known Riverbend equipment at this account: at least two coolant manifold assemblies. See install records HMS-INST-2019-04 and HMS-INST-2022-11.
Why this matters: The two units differ in material, outlet count, and tube size. Establishing that there are two — and how they differ — is what makes the rest of the brief possible. The obvious move, assuming it's the newer unit, is exactly the one the brief is careful with.
"2020 — routine first-year inspection on the 2019 port unit. No fault, no parts."
Source documents
harborline_records / ticket_2020_0117.mdservice ticket
Equipment: coolant manifold, serial RMW-CM-19-0114 — Tidewatch port genset. Routine first-year service check. No fault reported. Grommets in good condition. No weeping, no corrosion noted.
harborline_records / resolution_2020_0117.mdresolution record
Routine service completed. No parts consumed. No follow-up required. Manifold and grommets within normal condition for service age. Ticket closed same day.
Why this is cleanly assigned: Both the ticket and its resolution name the serial directly — RMW-CM-19-0114. This is what a confidently-assigned service event looks like, and it's the contrast that makes the 2023 ticket's ambiguity visible.
"2021 — grommet replacement on the 2019 port unit. Identity inferred from the genset reference; the ticket is a scanned legacy record."
Source documents
harborline_records / ticket_2021_0288.mdscanned legacy · medium OCR
Document origin: scanned legacy PDF, OCR confidence medium. Serial number field on this scanned ticket is not fully legible. The ticket says "port genset" — and the only Riverbend manifold on the port genset is the 2019 unit, serial RMW-CM-19-0114. Equipment identity inferred from the genset reference, not read directly from the scan.
harborline_records / resolution_2021_0288.mdresolution record
Equipment: Tidewatch port genset coolant manifold (2019 unit, RMW-CM-19-0114). Grommet replacement completed. Two LORD isolation grommets consumed (VND-LORD-01).
Why "inferred," not "read": The scan's serial field isn't legible. The brief is explicit that the identity comes from the genset reference plus the fact that only one unit sits on the port genset — a sound inference, but labelled as an inference, not presented as if the serial were read off the page.
"2023 — a routine check on 'the Tidewatch coolant manifold' that cannot be assigned to either unit."
Source documents
harborline_records / ticket_2023_0451.mdservice ticket · ambiguous
This ticket cannot be confidently assigned to either the 2019 or the 2022 manifold. It says "Tidewatch" and "coolant manifold" but not which genset, and the contract technician did not record a serial. Treat this service event as ambiguous.
harborline_records / resolution_2023_0451.mdresolution record
Resolution record carries the same gap as the ticket: it does not record which manifold was inspected. Cannot be used to establish service date for a specific serial.
Why the brief does not guess: Both the ticket and its resolution name "Tidewatch" and "coolant manifold" but never the genset side or a serial. The system does not silently attach the event to one unit. An unassignable service event does not reset either unit's service clock — which is why the 2019 unit still reads as overdue.
"The 2024 finding — dampness at outlet 7 of the starboard unit — has no resolution; the 2026 call may be a continuation of it."
Source documents
harborline_records / ticket_2024_0677.mdservice ticket · open
Confirmed slight dampness at the outlet the customer described — outlet position 7 of 10. Technician's note: "Looks like early grommet seep. Recommend grommet replacement at next opportunity." The 2026 service call may be a continuation of this unresolved 2024 finding.
Why "may be," not "is": The symptom matches and the unit matches, which is a strong link — but the brief does not collapse a likely connection into a certain one. It surfaces the probable continuity and lets the technician confirm it on site.
"The 2019 port unit is overdue for routine inspection by more than four years."
Source documents
standing_docs / service_interval_std.mdinterval standard
A manifold with no confirmed service in more than 30 months should be treated as overdue. 2019 unit: last confirmed service 2021-09-30. As of the 2026 call, that is more than 4 years — well past the 30-month overdue threshold. An ambiguous ticket that cannot be assigned to a serial does not reset the interval clock.
harborline_records / equipment_2019.mdequipment record
Last confirmed service: grommet replacement in 2021 (HMS-SVC-2021-0288). No confirmed service since 2021 that can be definitively tied to this serial.
Why the 2023 ticket doesn't count: The interval standard is explicit — confirmed service means a ticket and resolution tied to a specific serial. The 2023 ticket can't be tied to this serial, so it doesn't reset the clock. Last confirmed service stays at 2021, and the unit reads as 4+ years overdue.
"The 2019 port unit is clearly out of warranty — both disputed install dates land it outside."
Source documents
standing_docs / warranty_policy.mdwarranty policy
2019 unit: install date is in conflict between two Riverbend records (2019-03-18 vs 2019-04-22). Either way, a 36-month window from early 2019 closed in 2022 — this unit is well out of warranty regardless of which date is correct.
Why the conflict doesn't change this: The install-date conflict is real and the brief surfaces it — but here it happens not to be decisive. A 36-month window from either March or April 2019 closed in 2022. The brief is honest about both facts at once: the conflict exists, and in this instance it doesn't move the warranty answer.
"The 2022 starboard unit's window closed in 2025 — but the 2024 reported issue may keep a repair warranty-eligible."
Source documents
standing_docs / warranty_policy.mdreported-issue exception
An issue reported in writing while the unit is inside the warranty window remains eligible for warranty consideration even if the repair visit happens after the window closes — provided the original report is on file as a service ticket.
harborline_records / equipment_2022.mdequipment record
Warranty window: 2022-11-08 through 2025-11-08. As of the 2026 call, this unit is outside the original warranty window — though the 2024 open issue was reported while the unit was still under warranty.
Why this stays conditional: The build guide's hardest must-not-claim — the brief must not say the 2022 unit is "in warranty" or "out of warranty" flatly. Its status genuinely depends on whether a 2026 repair can be traced to the 2024 written report under the exception. The brief flags it as "confirm," and routes the question to the office.
"A repair on the 2022 unit needs 1.25" LORD grommets, not the 1.5" grommets used in the 2021 repair."
Source documents
standing_docs / lord_vendor_file.mdvendor file · part numbers
1.5" tube → LM-150-ISO, used on 2019-era 304L manifolds. 1.25" tube → LM-125-ISO, used on 2022-era 316L manifolds. The two grommet sizes are not interchangeable — they look similar but will not seal correctly if swapped.
harborline_records / parts_record.mdparts history
The 2021 repair consumed 1.5" grommets — but that was the port-side 2019 unit. A repair visit for either unit needs the correct grommet for that unit's tube size — confirmed against the serial, not assumed from the 2021 replacement.
harborline_records / ticket_2024_0677.mdtechnician note
Technician's note: "did not have 316L-compatible grommet stock on the truck for this configuration."
Why the part is contingent: The correct grommet depends on which unit it is — and identity isn't confirmed yet. The brief carries the right part forward for the likely unit, explicitly conditioned on confirming the serial. The 2024 technician's stock note is why "confirm before the truck rolls" is in the checklist.
"Grommet lead time for the 316L configuration should be confirmed before dispatch."
Source documents
standing_docs / lord_vendor_file.mdlead time
LM-150-ISO: typically in stock. LM-125-ISO: typically in stock; confirm before dispatch as 316L-config demand has been higher.
Why flagged: The vendor file itself singles out the 1.25" grommet as the one to check. The brief carries that instruction through rather than assuming stock — particularly since the likely unit is the 2022 316L one, which takes exactly that grommet.
"Confirm the unit on site — serial and genset side — before the visit."
Source documents
svc_call / call_intake.mddispatch note
Two Riverbend coolant manifolds may be in service at Harborline. Pull the install history before assigning a technician — do not assume this is the most recent unit.
Why this is the first checklist item: The dispatch note itself sets the rule — don't assume the recent unit. The brief's identity work points strongly to the 2022 unit but does not establish it, so confirming the serial on site is the gate before any parts or warranty decision is final.
"Carry 1.25" LORD grommets for the likely 2022 unit, and confirm 316L-configuration stock before the truck rolls."
Source documents
harborline_records / parts_record.mdfor the current call
If the equipment turns out to be the 2022 starboard unit — which the open 2024 issue suggests — the visit needs 1.25"-configuration LORD grommets, not the 1.5" grommets used in the 2021 port-side repair.
standing_docs / lord_vendor_file.mdservice note
A repair visit must confirm the unit's tube OD — by serial, against the equipment record — before pulling grommet stock.
Why "likely," carried into the checklist: The brief doesn't make the technician arrive empty-handed waiting for confirmation, nor does it pretend the unit is settled. It says: bring the part the records point to, and confirm both the unit and the stock before relying on either.
"This is most likely a continuation of a known 2024 open finding — not a new failure — and the warranty question turns on the reported-issue exception."
Source documents
harborline_records / ticket_2024_0677.mdthe open finding
The 2026 service call describing weeping on a Riverbend manifold may be a continuation of this unresolved 2024 finding. Recommended grommet replacement was never scheduled.
standing_docs / warranty_policy.mdreported-issue exception
An issue reported in writing while the unit is inside the warranty window remains eligible for warranty consideration even if the repair visit happens after the window closes.
Why this is the closing context: The brief hands the technician a frame, not just facts — most likely a known issue resurfacing, with a live warranty question the office should settle before the visit. Every piece of it is sourced; none of it is asserted past what the records support.
