Technical Reporting

Forms compliance plus engineering insight.

A vessel files dozens of technical forms a month. Two questions matter: Are they being submitted on time? (compliance) and What do the numbers in them actually tell us? (analysis) Most forms-management systems answer only the first. This pipeline answers both, on every monthly submission, automatically.

Two views, one pipeline

Submission view  →  Is each form in, on time?
Analytical view  →  What do the filed numbers say?

The submission view catches the forms problem. The analytical view catches the engineering problem. They are independent failure modes: a vessel can have 100% submission rate and still have a wear-down problem buried in the deflection report nobody read.

Submission — lateness buckets

For every required form, the pipeline tracks last submitted date, next due date, and lateness. Three windows are reported: previous month, rolling 12 months, and DOC-wise rollup.

Window	Bucket
0–7 days late	Acceptable slip
8–30 days late	Concerning
31+ days late	Compliance gap — escalate
Not submitted	Black box — dependent analyses are blind

Submission rate per vessel per period:

Submission rate % = N_submitted_on_time / N_mandatory × 100

Worked example — MV POSUN

End-of-April submission review:

Form	Last submitted	Status	Notes
ME performance	2026-04-05	In Order	—
AE performance	2026-04-08	In Order	—
AE LO consumption	2026-03-12	Late 18 days	Recurring — late 3 of 6
LO shore analysis	2026-02-25	Compliance gap	35 days late
ME bearing clearance	2026-04-15	In Order	Crosshead 4 wear at 78% — monitor
ME scrape-down	2026-04-15	In Order	Iron 165 ppm — normal
Paint inventory	2026-03-30	Late 8 days	Recurring — late 3 of 6
Walkie-talkie inventory	2026-04-12	In Order	All 8 units OK

Submission rate: 84% — below the 95% threshold, flagged.

Analytical findings routed to other pipelines:

ME crosshead 4 bearing at 78% wear → ME performance and PMS for replacement planning.
LO shore analysis 35 days late → blind spot on lube oil for the past month, escalated.

What each form tells us

ME bearing clearance — wear-down analysis

Main bearings, bottom-end bearings, crosshead bearings, thrust-pad clearance — measured against the maker’s wear-down curve:

Wear % = (C_measured − C_new) / (C_condemn − C_new) × 100

Wear %	Status
≤ 50%	OK
50% to 80%	Monitor
80% to 100%	Plan replacement
> 100%	Condemn — must be replaced

ME scrape-down — iron content and liner wear

Iron content from cylinder oil scrape-down samples, residual BN variation, stuffing-box leakage status. Iron content is a leading indicator of liner / ring-pack wear:

Iron content	Interpretation
< 100 ppm	Normal break-in
100 to 250 ppm	Active wear, monitor
250 to 500 ppm	Accelerated wear, investigate
> 500 ppm	Severe — engine inspection required

Stuffing-box leakage logged here cross-references the lube-oil consumption variance form.

All forms covered

Form	What the analytical layer extracts
ME performance	Running hours, SFOC, Pmax, Pcomp, exhaust temp, feed rate → routes to ME performance
AE performance	Per-AE equivalent → routes to AE performance
ME bearing clearance	Wear-down % per bearing position
ME scrape-down	Iron content, residual BN, stuffing-box status
ME scavenge inspection	Feed rate, lubrication, deposit formation, coating thickness, axial clearance
Deflection (ME and AE)	Crankshaft web deflection vs tolerance — major-overhaul flag
Lube oil condition	TBN, water content, viscosity, renewal status → routes to lube oil
Lube oil monthly	ROB, consumption, FOC, renewal status
ICCP performance	Aft / midship / forward current outputs and reference voltages
Motor condition	Megger readings and current draw on critical motors
Paint inventory	ROB vs reorder threshold, drydock prep adequacy
Chemical inventory	Water-treatment and cleaning chemicals vs spec
Walkie-talkie inventory	Count, condition, charging — PSC inspectors check this
Month-end consolidated	Roll-up: every analyzed form, worst findings first

Repeat-delay detection

A form that’s late once is a slip; a form that’s been late three months in a row is a process problem. The pipeline surfaces forms that have failed three or more consecutive periods:

RECURRING LATE SUBMISSIONS

ME deflection           →  Late 4 of last 6 months
Lube oil shore analysis →  Late 5 of last 6 months
Paint inventory         →  Late 3 of last 6 months

Recurring late submissions usually trace to one of:

Form owner rotated off vessel, handover incomplete
Form moved into master compliance system but engineers not notified
Form depends on a sample or measurement that is itself overdue
Form deprecated but not removed from the mandatory list

The first three are recoverable with one conversation.

Submission status — code snapshot

def compute_submission_status(forms, today):
    rows = []
    for form in forms:
        last_submitted = parse_date(form.get("submittedDate"))
        next_due       = parse_date(form.get("nextDueDate"))

        if last_submitted is None:
            status = {"text": "Never submitted", "color": "red"}
        elif next_due is None:
            status = {"text": "In Order", "color": "green"}
        else:
            days_diff = (next_due - today).days
            if days_diff < 0:
                if abs(days_diff) <= 7:
                    status = {"text": f"Late {abs(days_diff)} days", "color": "orange"}
                elif abs(days_diff) <= 30:
                    status = {"text": f"Late {abs(days_diff)} days", "color": "red"}
                else:
                    status = {"text": "Compliance gap", "color": "red"}
            elif days_diff <= 14:
                status = {"text": f"Due in {days_diff} days", "color": "orange"}
            else:
                status = {"text": "In Order", "color": "green"}

        rows.append({
            "form":           form["name"],
            "last_submitted": last_submitted,
            "next_due":       next_due,
            "status":         status,
        })
    return rows
