LPG Vessel Substitution: Reopen the Right Decisions

Overview

The coordinator should identify the current authorised candidate, the proposed substitute and the decisions that depend on vessel identity. This allows the commercial team to assess the change without either assuming acceptance or treating every historical document as if it must be recreated from the beginning.

Key takeaways

• Record a substitution as a proposal until the relevant authority and reviews are complete.
• Link existing decisions to the vessel and programme they actually cover.
• Ask responsible reviewers what remains applicable and what needs a new response.
• Reconcile commercial terms and receiving information before issuing revised instructions.
• Preserve the earlier candidate's record as part of the decision history.

Define the proposed substitution precisely

Capture the requester's identity, the proposed replacement reference, the reason stated and the timing of the request. Identify the current programme version and the point at which the business needs a decision.

Do not rely on informal similarity descriptions. The relevant parties need the replacement's actual information through the authorised source and the proposal it is intended to perform. The coordinator should obtain that evidence without interpreting technical equivalence.

Also establish the authority for the substitution process. The relevant agreement may contain provisions that require commercial or legal interpretation. Check the current wording and refer the question appropriately instead of assuming that a party's ability to propose a replacement establishes its right to implement one.

The working record should keep the existing candidate and proposed substitute distinct. Until the change is authorised, recipients need to know which is the current basis and which is under consideration.

Map decisions tied to vessel identity

Review the file for responses and instructions that name the original candidate or rely on its information. These may include specialist reviews, receiving correspondence, commercial approvals and document requests.

Ask each responsible decision owner whether its earlier response remains useful and what evidence it needs for the substitute. Some information may remain relevant to the cargo or programme; other elements may need a fresh review. The coordinator should record that distinction rather than applying an indiscriminate reset.

The map helps the team direct effort to affected decisions while retaining useful evidence that does not depend on the original vessel. It also identifies gaps that would otherwise remain hidden behind a broad substitution status.

Keep commercial and specialist responses distinct

A counterparty may be commercially willing to consider the substitute while a specialist review is still open. A receiving contact may acknowledge the proposal without confirming its arrangement. Preserve each response's actual meaning.

Use a decision register with separate rows for commercial authority, evidence receipt and scoped review responses. Do not collapse them into a single approved label until the authorised process supports that conclusion.

If a reviewer requests additional information, route the precise question to the designated source. Record the next action and expected response rather than interpreting the request as rejection or treating it as an administrative formality.

Where timing pressure increases, escalate the unresolved decision and its commercial consequence. The coordinator should not infer technical acceptability from urgency. Management needs to see what remains unknown so it can assess the available options with appropriate advice.

Preserve the option to retain the original programme

A substitution enquiry can consume attention while the status of the original candidate becomes uncertain. Ask the responsible commercial parties whether and until when the existing option remains available.

Record the fallback in concrete terms. If the substitute is not accepted within the decision window, what proposal will the business pursue? Does it retain the original candidate, seek another arrangement or revisit the cargo commitment? The answer belongs in the commercial decision note.

Avoid assuming that withdrawing the substitution request restores the earlier state automatically. Another party may have acted on an instruction or released an option in the meantime. Reconcile the actual status before describing the fallback as available.

If the desk asks parties to investigate both candidates, label the parallel work clearly. They should know which information requests are exploratory and who will issue the final authorised direction.

Fictional case: the similar candidate

A fictional LPG operator proposes a replacement candidate during negotiation. The commercial message describes the vessel as similar to the original. The charterer's coordinator updates the working schedule with the new name and assumes the receiving correspondence can be reused.

A reviewer notices that the earlier response specifically identifies the original vessel. The coordinator restores separate records for the current candidate and the proposed substitute, then sends a scoped request asking what information is needed for the replacement.

The receiving contact requests updated evidence, while the commercial lead reviews the substitution process under the relevant agreement. The programme estimate is also refreshed through the responsible source. The team records each workstream separately rather than waiting for a vague overall approval.

Once the necessary responses and authorised commercial direction are available, the coordinator issues a controlled change note. The earlier instructions are superseded explicitly, and the current programme reference identifies the replacement. The similarity description no longer carries a decision it was never meant to prove.

Release a reconciled change package

The approved change note should identify the new candidate, current programme, supporting response references and any conditions that remain. It should explain which earlier instructions are replaced and who needs to acknowledge the update.

Review the surrounding documentation for stale vessel references. A changed schedule can coexist with an old document request or customer note unless the coordinator checks the affected records systematically.

Do not redistribute restricted review material merely to demonstrate completion. The change package can identify the scoped decision and authorised evidence route while respecting access arrangements.

After release, assign any residual tasks to named owners. A substitution can be commercially authorised while some follow-up documentation remains due; those tasks should not disappear behind the closed change status.

Retain a useful history

Keep the original candidate's file linked to the earlier proposal rather than deleting it. It explains the negotiation and the basis of decisions made before substitution.

Record why the change was selected and what alternatives were available at the time. This supports later review of the process without relying on the eventual outcome to reconstruct what the team should have known.

Common mistakes

A similar vessel description is not evidence that earlier scoped decisions cover the replacement. Ask the responsible parties to confirm applicability.

Another mistake is to update the vessel name before establishing whether the proposal is authorised. Keep current and proposed states distinct during review.

Finally, avoid assuming the original candidate remains available as a fallback. Confirm its status through the responsible commercial route before relying on it.
