Verbatim query: What is the shipping lead time to the Bergen depot?
Reference answer: 6 working days comes back; 11 working days must NOT come back
Same mutation-slice collection as TC98 (never mixed with the SS-v1 stable slice).
Change applied via delete + re-add under the IDENTICAL filename (the API has no
PATCH/update-in-place endpoint for a document -- PATCH .../documents/{id} is 405,
only DELETE is allowed -- so this is the correct way to operationalize an in-place
content 'change' without silently re-testing 'add' via a rename). Old B02 document_id
deleted, new B02_shipping_lead_times.pdf (same filename, Bergen row 11 -> 6 working
days) ingested and confirmed indexed. Per ground truth: MS-v2 digest a1de5a13d3f0d9a1
(5 docs). The old value (11 working days) appears nowhere else in the corpus, so its
continued return could only mean the index hadn't caught up.

answer: The shipping lead time from the central store in Bristol to the Bergen depot is **11 working
days** via road and ferry groupage. This assumes standard groupage service; consignments handed over
after the 15:30 cut-off travel the following working day. Dangerous goods containing a lithium cell
above the threshold require an additional **2 working days**.

# Shipping Lead Times
Central store, Bristol - outbound to depots and customer sites
## How to read this
Lead times are quoted from the courier collection, not from the moment a stores request is raised.
Anything handed over after the 15:30 cut-off travels the following working day, and the lead time
starts then.
| Destination |
Route |
Lead time |
| Aberdeen |
Road, own vehicle |
3 working days |
| Lerwick |
Road and ferry |
4 working days |
| Gothenburg |
Road and ferry, groupage |
7 working days |
| Esbjerg |
Road and ferry, groupage |
9 working days |
| Bergen |
Road and ferry, groupage |
11 working days |
Lead times to the Nordic depots assume a groupage service. A dedicated vehicle is quoted on request
and is normally quicker, but is not held against these figures.
## Dangerous goods
Any consignment containing a lithium cell above the threshold needs a signed packing declaration and
travels on a different service. Add two working days to the figures above, and involve a trained
shipper before booking. Two people in the building hold the certification.
## Returns
Inbound lead times are not the outbound figures in reverse. A return from a depot travels on the
next scheduled groupage movement rather than on collection, so plan a return around the movement
rather than around the courier.
## Who maintains this
The stores controller reviews these figures against the carrier's performance each quarter and
changes them here when the carrier's own schedule changes.

Extracted Text: # Depot bulletin - a new depot in the region
For the service desk, the Bergen depot and central stores.
## What is opening
The Tromso depot opens on 14 October 2026 and will hold four Tolvan C5 loan units and a full Brannoc
spares kit. It is the third depot in the network and the first
above the Arctic Circle.
## Why
Response to the northern fields has been limited by the sailing time from
Bergen rather than by engineering. Holding loan stock and a spares kit locally
removes the leg that has cost the most time on recent tickets.
## Staffing
One engineer and a shared stores controller, working 07:00 to 15:00 local time,
Monday to Friday. Out of hours the northern sites continue to page the existing
duty engineer rota; the new depot does not change how a fault is reported.
## What to do differently
Stop routing northern loan requests through Bergen once the depot opens. Ring
the new depot directly. Bergen keeps its own loan pool and its own spares kit,
and nothing moves out of Bergen to stock the new site.
## What is not changing
Calibration stays in the laboratory. The new depot does not calibrate, does not
break a calibration seal, and does not open a pressure housing.

Extracted Text: # Approved Supplier List
*Fenwake Instruments Ltd - *parts fitted to instruments in service*
## 1. Scope
This list names the suppliers approved for parts fitted to instruments in service. A part from a
supplier not on this list is not fitted, whatever the lead time pressure, because the part becomes
part of a calibrated instrument.
## 2. Single-source parts
The sole approved supplier of the H-clamp bracket is Ardwyn Fabrication (Newport), quoted per batch
of fifty. The bracket is machined to our drawing and no second source has been qualified, so a
shortage here stops the fitting rather than being worked around.
Where a single-source part is short, the stores controller tells the service desk lead the same day.
A substitution is authorised by the head of service operations in writing, and the instrument record
carries the substitution.

File Name: B01_oncall_rota_notes.md
Extracted Text: # On-call rota - working notes
For the service desk lead. Not a contractual document.
## Shape of the rota
The duty engineer rota runs Monday to Monday, handing over at 09:00. Four
engineers are on the rota at any time, which puts each of them on call one week
in four. An engineer who is on call does not travel offshore in the same week.
## Cover for absence
Where an engineer on the rota is absent, the service desk lead swaps rather
than doubles: the week is given to the next engineer in the cycle and the
absent engineer takes theirs. Doubling a week has caused more missed pages than
any other cause and is not done.
On a statutory non-working day the rota does not change. The standby allowance
for that week is paid at the enhanced rate set out in the handbook.
## Handover
Handover is a call, not a message. The outgoing engineer walks the incoming one
through every ticket still open, what has been tried, and what the customer has
been told. A ticket that changes hands without that call is the single most
common source of a customer being told two different things.
## Paging
The out-of-hours number pages the engineer on call. Where the page is not
acknowledged, it escalates to the service desk lead automatically, and then to
the head of service operations. Test the pager at the start of every week
before the handover call ends.
score=0.3667 document_id=d9467dab-9f21-4868-8ddb-b6ca407f7634
## 4. Qualifying a new supplier
A new supplier is qualified on a first-article inspection and a documented material certificate.
Qualification is recorded against the part, not against the supplier as a whole: a supplier approved
for one part is not thereby approved for another.
## 5. Review
The stores controller reviews this list each quarter with the workshop manager. A supplier that has
missed two consecutive delivery commitments is reviewed regardless of the schedule.

Site access - standing notes for engineers
Central store and service desk. Not a contractual document.
PERMITS
Most customer sites need a permit raised before the day, not on it. Raise it
through the customer's own system and take the reference with you; a permit
that exists only in an inbox is a permit that will not open a gate.
A permit is site-specific and person-specific. An engineer who swaps onto a
job at short notice needs their own, and the swap is the reason most access
is refused at the gate.
INDUCTIONS
Water treatment sites and harbour authorities run their own inductions,
valid for twelve months. The service desk keeps the expiry dates against
each engineer. An induction that expires mid-job is treated as expired for
the whole job.
TIDE AND ACCESS WINDOWS
Intake structures are reachable only around low water. Plan the visit around
the window and tell the customer which window you are working to, so that a
delayed start is a conversation rather than a surprise.
KEYS AND CODES
Never write a gate code on a job sheet. Codes are held by the service desk
and read out on the day. A code that has changed is reported the same day,
because the next engineer will otherwise repeat the wasted journey.
VESSELS
On a vessel, the master's instructions take precedence. Board with your own
survival certification in date; the vessel will check it and will refuse
boarding without it.
WHAT TO DO IF ACCESS IS REFUSED
Do not argue at the gate. Ring the service desk, who will ring the
customer's site contact. Record the refusal and the reason on the ticket
before leaving, while the detail is still accurate.
