BIMCO's Documentary Committee has approved the Energy Saving Device Retrofit Addendum 2026, the Copenhagen-based shipping association's first standardised framework for splitting the cost of energy-saving retrofits between shipowners and charterers mid-charter.

The decision followed months of consultation with shipowners, charterers and the insurance sector. Drafting drew representatives from Swedish operator Stena Rederi and Cargill Ocean Transportation, the ocean freight arm of U.S. agricultural trader Cargill, BIMCO confirmed.

Why does this deadlock exist?

Under a standard time charter, owners pay for hardware bolted to hulls and decks. Charterers control voyage decisions and reap most of the resulting fuel savings during the charter period. Owners can ask for higher hire. In practice, retrofit deals have been stuck.

The mismatch has stalled investment even where efficiency gains were measurable, the organisation said. Owners who would otherwise fund scrubbers, rotor sails or hull coatings have balked when the payback runs to the charterer. Charterers have refused to pay for hardware they do not own.

What does the 2026 addendum actually change?

The framework covers three commercial buckets: installation costs, off-hire time, and the financial gains from reduced fuel burn. Rather than impose fixed percentages, it sets out a negotiation structure the parties adapt per project. BIMCO said the document is technology-neutral and accommodates different energy-saving systems, plus the cost implications of current and incoming environmental regulations.

Owners keep ownership of the equipment. The addendum introduces a contractual mechanism to recover part of the outlay from charterers, tied to fuel savings measured in service. Recovery terms stay negotiable case by case. No default split applies.

Who backed the drafting?

BIMCO said development reached its final stages in June, following consultation with industry participants and its Documentary Committee. The drafting committee included representatives from Stena Rederi and Cargill Ocean Transportation. Insurance sector voices joined the process too, though BIMCO named no specific underwriters.

When does it land, and where does it sit?

The text now ships through BIMCO's SmartCon contract platform, paired with explanatory guidance. The Documentary Committee — BIMCO's standing body for standard shipping contracts — gave the approval.

What does it mean commercially?

For shipowners, the addendum removes one barrier to retrofit spending where fuel benefits would otherwise flow to the charterer. For charterers, it formalises a share of retrofit economics they may already negotiate ad hoc, with less bespoke legal work per project. Insurance involvement in drafting signals coverage and liability questions were considered.

The timing matters. EU ETS shipping allowances now carry a price. FuelEU Maritime penalties ramp from 2025. IMO carbon intensity targets tighten from 2027. A 2026 addendum lands squarely in that trajectory, giving owners and charterers a common reference point before more tonnage heads into yards.

For forwarders and pool operators, the ripple effect runs indirect but real. Charter parties govern the tonnage they book. Any shift in retrofit economics eventually changes bunker consumption forecasts, contract pricing and the carbon-adjusted freight quotes major shippers now demand.

The first retrofit projects booked under the new addendum will set the precedent. Watch how 50-50 splits, or anything close, get priced in a tightening carbon market.
