Analyst notes (75)

Engine flags each clause needing customer review. First 5 shown below.

  • CANCELLATION_CLAUSE: customer verify laycan window em CP. Laydays = earliest NOR; cancelling date = latest arrival before charterer pode cancel. Vessel early: charterer pode delay laytime start. Vessel late: charterer cancels sem liability. Owner improper cancellation: damages for market loss (ballast + freight). BIMCO Cancelling Clause 2002 standard.
  • LAYCAN_RIDER_EXTENSION: customer verify rider clauses. "Slip laycan" permits N-day extension via mutual consent. "Firm laycan" no slippage. "Substitute laycan" entire window replaced. LATAM CPs (Synacomex/Norgrain): laycan tied to grain elevator availability. Brazilian iron ore: mining production schedule. Argentine grain: Up-River elevator. Mutual consent required (no unilateral). Addenda document changes.
  • NOR_VALIDITY_BASIC is draft-pre-sme: does not check WIPON/WIBON/WIFPON/WCCON, free pratique, customs, pumping readiness
  • NOR_NOTIFICATION_METHOD: customer verify CP notification method clause. Asbatankvoy Cl. 6: telex/written. BPVoy 3: fax confirmed by telex. Modern CPs: email increasingly accepted. Default English law: any reasonable method. The Port Russell: enumerated list = exhaustive (closed). Recipient: charterer ou authorised agent (não pilot/port authority/terminal). Waiver via subsequent action sem protest cures defect.
  • ANTI_TECHNICALITY_CLAUSE: customer verify CP. NYPE 2015 cl. 11(b) standard 3 banking days cure. BIMCO Anti-Technicality 2002 standard. Three notice elements required: (1) identify default; (2) state cure period; (3) warn of withdrawal. The Afovos [1983]: premature notice invalid. The Li Hai [2005]: clear banking days computation excluding day of notice. The Nanfri: bona fide deductions bar withdrawal. Cannot validate fundamentally bad NOR — só minor defects.

Sample dispute letter (FS-004)

Below is the actual letter our engine would draft for this case. Sent by you, the Charterer, to the Owner. Cites CP clauses + LMAA precedents + your engine calculation. Editable in the platform before sending.

**Subject:** DEMURRAGE DISPUTE — MV CARGILL VOYAGER — VOYAGE 2026-Paranagua-Rotterdam-006 — USD 38,000 claimed, despatch USD 22,000 owing

**To:** Pacific Basin Shipping Ltd.
Demurrage Department
Hong Kong

**From:** Cargill International SA
Marine Operations — Geneva
Reference: CARG-INT-DEM-2026-006

**Date:** 28 May 2026

---

Dear Sirs,

We refer to your demurrage invoice dated [date], claim sum **USD 38,000.00**, in respect of voyage 2026-Paranagua-Rotterdam-006 (MV CARGILL VOYAGER, soybean Brazil GMO, Paranaguá→Rotterdam, Norgrain 89 form).

We have completed an independent audit and respectfully dispute the claim. The vessel was entitled to **despatch USD 22,000.00**, producing a net amount **due to Charterer of USD 60,000.00**. The principal issue is whether the **berth-charter doctrine** correctly excludes the pre-berthing congestion time from laytime — your calculation appears to have included this incorrectly.

## 1. Engine calculation

- **Laytime allowed:** 48.00 h (Norgrain 89 + SHINC + 6h turn time per CP Box 16)
- **Laytime used:** 24.00 h (per SoF events, **excluding 2-day berth congestion wait at anchorage**)
- **Delta:** -24.00 h
- **Despatch rate:** USD 11,000/day × 24 h = **USD 22,000.00 owing to Charterer**

## 2. Norgrain 89 berth-charter doctrine

The Norgrain 89 form is by default a **berth charter** (Charterparty Clause 2; Norgrain Code §3.1). Under the ARRIVED_SHIP_DOCTRINE and COMMENCE_AT_BERTH_ONLY rules in our engine (sources: Schofield §2.40, Cooke Ch. 15, *The Johanna Oldendorff* [1974] AC 479 HL):

a. The "arrived ship" doctrine requires vessel to **reach the berth** (not merely the port) before NOR is validly tendered as a berth-charter NOR.
b. Time spent waiting at anchorage for berth availability is **owner's risk** under a pure berth charter without WIBON.
c. Norgrain 89 does **not** include WIBON by default.

SoF p. 1 ¶1 records: *"Anchored — Paranaguá anchorage"* at 06:00 UTC 8 May 2026.
SoF p. 1 ¶5 records: *"Berthed after waiting — Berth 215 Cattalini"* at 16:00 UTC 10 May 2026.

The 2-day, 10-hour period at anchorage (**58 hours**) is **owner-risk berthing time**, not laytime. Laytime commenced at berthing per Norgrain 89 berth-charter default. Your calculation includes this period and is therefore wrong by 58 h × USD 22,000/day = **USD 53,166.67 over-claimed**.

## 3. Cattalini Terminal efficient turnaround

Once berthed, 60,000 MT of soybean cleared in 5 days at Cattalini Terminal. Despatch crystallised at COB on 15 May 2026 at 19:30 UTC.

## 4. Applicable authorities

- **Norgrain 89 Clauses 2, 16, 19** (berth charter, laytime, despatch)
- **The Johanna Oldendorff** [1974] AC 479 HL (arrived-ship doctrine — port vs berth charter)
- **The Maratha Envoy** [1978] AC 1 (WIBON construction)
- **Schofield "Laytime and Demurrage" 8th ed** §2.40 (berth charter strict)
- **Cooke "Voyage Charters" 5th ed** Ch. 15

## 5. Demand

We demand withdrawal of the USD 38,000 invoice and payment of despatch USD 22,000 within fourteen (14) days.

## 6. Reservation of rights

All Charterer's rights expressly reserved.

Yours faithfully,

**Cargill International SA**
