After a string of fixtures where “war risk surcharge” felt like a black box, you want line-of-sight: who pays, how it’s calculated, and what to do before your ship noses into a listed area. This guide breaks down Additional Premium (AP), crew bonuses, K&R/LOH add-ons, and the clauses that make charterers, rather than owners, carry the bill when their orders send a ship into harm’s way.
Understand Additional Premium (AP), crew war bonuses, K&R/LOH add-ons, and who pays under time vs voyage charters in 2025.
What Is the War Risk Surcharge?
When a voyage order passes through a “Listed Area” (high-risk zone), owners must buy extra war cover for the period of exposure. Insurers charge an Additional Premium (AP) for a short window (commonly 7 days) as a percentage of hull value. Owners may also need add-ons: K&R, War Loss of Hire, and crew war bonuses set by employment terms or union agreements.
Typical Components
- Hull War AP (7-day breach)
- P&I War (excess/extended)
- War Loss of Hire (optional)
- K&R (optional, voyage-dependent)
- Crew war/area bonus & security costs
Who Pays Under Charterparty?
| Scenario | Time Charter (CONWARTIME 2025) | Voyage Charter (VOYWAR 2025) |
|---|---|---|
| Orders into a Listed Area | Charterers reimburse “Insurance Costs” (war AP, agreed add-ons, crew bonuses) when their orders expose the ship to war risks. Owners notify costs as practicable, preferably before entry. | Similar principle: if the agreed voyage requires entry, freight/terms should reflect war risk; owners may refuse unsafe orders not contemplated or claim revised terms. |
| Refusing Dangerous Orders | Owners may refuse where risk is unacceptable, subject to clause thresholds (e.g., actual/expected exposure). Safety overrides. | If risk escalates pre-loading or mid-voyage, owners may seek alternative safe orders or expenses; wording matters. |
| Proof & Discounts | Owners to evidence premiums/bonuses; reimbursement is net of any discounts/no-claims benefits for that voyage. | Practice varies by form/addenda; align on documents accepted as proof. |
Anatomy of AP & Add-Ons
Hull War AP
% of Agreed Hull Value for a 7-day “breach” period. Reset/extend if exposure lasts longer. Rate depends on corridor, security posture, threat level.
P&I War / Excess
Restores liability limits while inside the area. Wordings follow club circulars; may require separate binders or notice.
Crew & Security
War area bonuses, guards/embarked security, convoy fees, re-routing watches. Evidence via payroll or crewing manager letters.
Quick Calculator: Estimate War Risk Cost Pass-Through
Approximate the AP and per-day recovery for a transit. This is a simplified tool—insurer quotes and your charterparty govern.
AP ≈ Hull Value × (AP% / 100) × (Exposure ÷ 7). Results are indicative; actual quotes can differ by routing, escorts, and underwriter terms.
Charterer & Owner Playbook (Actionable)
Before Fixing
- Identify any legs passing through Listed Areas and estimate exposure days.
- Agree who buys what: AP, K&R, LOH, crew bonuses, security, convoys.
- Insert cost-recovery language mirroring CONWARTIME/VOYWAR 2025.
- Require owners’ timely notice and evidence (invoice, crewing confirmation).
Pre-Entry to the Area
- Owners to notify AP quotes and validity; share route and speed plan.
- Confirm security posture (escorts, convoy, guards) and who pays.
- Align on safe alternatives if risk escalates (re-route, delay, cancel).
- Clarify documentary proof required for reimbursement (net of discounts).
Clause Focus: What to Check
Definitions
“War Risks,” “Area exposed to War Risks,” “Insurance Costs.” Ensure alignment with the 2025 wording used in your form/addenda.
Evidence & Netting
Invoices, crewing confirmations, and any no-claims/discounts netted off the reimbursement.
Refusal & Alternatives
Right to refuse unsafe orders and process for nominating an alternative safe route/port.
Note: 2025 Hotspot Example
Red Sea / Bab el-Mandeb / Gulf of Aden routes continue to attract heightened underwriting scrutiny. Expect dynamic AP quotes, possible crew bonus triggers, and documentary evidence requests prior to entry.
Treat war risk surcharges as a transparent pass-through: define the exposure, collect quotes early, share evidence, and peg reimbursement to the actual risk window. With the 2025 clause updates, most disputes vanish when both sides agree the paperwork—and the safety triggers—upfront.
