Shipping, Demurrage & Market Intelligence built on Experience, Structure, and Facts

a2b Ltd provides specialized shipping and commercial support across the shipping industry, with a strong focus on chartering, voyage execution, post-fixture performance, and demurrage.

We help trading companies, shipowners, and operators protect margins, control exposure, and resolve disputes by rebuilding positions properly — using facts, contracts, and operational reality.

Modern shipping moves fast — and the cost of being slightly behind is real. We stay ahead by combining market awareness with operational detail and strict charter party logic — to protect margins, prevent leakage, and build positions that stand up under scrutiny.

ABOUT

a2b Ltd is an independent shipping advisory firm focused on tanker chartering, voyage operations, and post-fixture matters, including demurrage.

Our work is built on more than three decades of hands-on experience in shipping, covering chartering and daily operations through to post-fixture handling and final settlement. Alongside execution, we follow the markets closely and continuously — maintaining extensive historical and live datasets covering chartering activity, freight behaviour, and the day-to-day factors that ultimately drive time, cost, and exposure.

This perspective is shaped by long involvement in real fixtures and real voyages, across a wide range of ports and terminals. It allows us to recognise, early and reliably, where inefficiencies arise, where assumptions fail in practice, and where cost exposure quietly builds.

We operate where shipping decisions are actually made: under time pressure, commercial constraint, and operational reality — where small, overlooked details quietly accumulate and turn into real cost. By applying experience to fine-tune decisions at each stage, we help clients avoid unnecessary exposure and deliver measurable savings, ensuring positions hold up in practice, not just on paper.

Services

From fixture to final settlement — we focus on the decisions that protect margins and prevent unnecessary cost.

In shipping, cost leakage rarely comes from one major failure. It comes from a series of small, overlooked decisions — at fixture stage, during execution, and in post-voyage handling — that quietly compound into significant financial exposure.

Our role is to intervene across the full chain, where experience, structure, and precision directly translate into measurable cost savings.

Chartering & Market Intelligence

The most expensive demurrage cases are usually decided before the vessel is fixed.

With decades of direct chartering and shipping experience, we identify where standard fixtures hide future operational and demurrage risk. Vessel selection, laytime terms, additional clauses, and operational flexibility are rarely neutral — they either protect margins or erode them later.

We focus on:

  • Avoiding vessels and structures that limit operational control
  • Closing contractual gaps that later become demurrage exposure
  • Aligning charter party wording with how voyages actually perform
  • Using market context to validate assumptions and challenge unrealistic expectations
  • Strengthening commercial positions during disputes with factual market reality

Small details at fixture stage often decide the final cost — long before execution begins.

Operations & Voyage Execution

Most cost exposure materialises during execution.

Delays, missed notices, weak documentation, and unclear instructions are rarely isolated issues. They are operational failures that directly translate into time, cost, and weakened claims positions.

We provide hands-on operational oversight to:

  • Maintain control of charter party performance
  • Identify exposure before it becomes irreversible
  • Ensure records and statements of facts withstand scrutiny
  • Prevent avoidable time loss from turning into claims

Operational discipline is one of the most effective — and underused — cost control tools in shipping.

Post-fixture & Final Settlement

Weak structure after the voyage is where money leaks quietly.

Post-fixture handling is where positions are either consolidated properly — or allowed to fragment into disputes, delays, and unnecessary concessions. Many outcomes are determined by documentation quality, internal consistency, and the discipline applied during close-out.

We support clients with:

  • Rebuilding complete and defensible post-voyage files
  • Aligning recaps, charter parties, SoF, and voyage records into one coherent position
  • Identifying where exposure accumulated — and why
  • Strengthening settlement strategy before escalation becomes expensive

Post-fixture is where final outcomes are decided — and where precision protects value.

Demurrage & Time-Related Matters

Demurrage is where margin leakage becomes visible.

In practice, most demurrage is challenged — but very little is challenged in a way that actually holds once pressure increases. Weak structures, fragmented documentation, and selective arguments collapse quickly when escalated.

Demurrage is a specialist discipline within our wider shipping expertise. We rebuild cases properly, using the full contractual, operational, and market framework — not isolated arguments.

Our involvement regularly results in:

  • Material reduction of demurrage exposure
  • Recovery of amounts that would otherwise be conceded
  • Faster, more favourable settlements
  • Avoidance of prolonged and costly escalation

We build positions that survive scrutiny — and deliver real financial outcomes.

When shipping is managed correctly from the outset, outcomes become controlled — not recurring surprises.
