Geoquip Marine Operations AG v Tower Resources Cameroon SA & Anor

A contractual payment obligation triggered by delivery of a compliant preliminary report is not defeated merely because the report is late, unless the contract makes timely delivery a condition or time is expressly of the essence. Contractual invoicing provisions do not themselves create an entitlement to charges absent an independent contractual basis.

An estoppel by convention requires a clear shared assumption or acquiesced assumption, conduct manifesting assent, reliance connected with subsequent dealings, and circumstances making resiling unjust or unconscionable. Contractual estoppel cannot be founded on recitals which record facts but do not allocate legal responsibility. A guarantor remains liable after a variation where the guarantee contractually permits the principal parties to make the variation.

Geoquip provided offshore geotechnical investigation services to Tower Cameroon under a contract guaranteed by Tower plc. Geoquip claimed the unpaid balance of the contractual lump sums and standby charges arising while its vessel awaited governmental approvals and security arrangements.

The defendants argued that the balance was not payable because a compliant preliminary report had not been delivered within the contractual period, and that no contractual or estoppel-based entitlement to standby charges existed. They also disputed Tower plc’s continuing liability as guarantor after an extension agreement was signed by Geoquip and Tower Cameroon alone.

The court therefore considered the construction of the contract and extension agreement, estoppel by convention, contractual estoppel, and the effect of the extension on the guarantee.

1. Contract price. Geoquip was entitled to the outstanding contractual lump sums. Payment was conditional upon completion of the work and delivery of a compliant preliminary report. The report first supplied was non-compliant because it omitted the required spudcan analysis. Once that information was supplied, Tower Cameroon’s payment obligation engaged. The reporting timetable was not a contractual condition or a term making time of the essence. Even if it had been, the available remedies were prospective termination and damages, neither of which had been exercised or claimed.
2. Standby charges. Geoquip was not entitled to standby costs under the contract. The provisions concerning company representatives, faulty company data, force majeure and suspension did not apply. The exchanges between the parties did not amount to a contractual notice of suspension. Although the necessary approvals and security arrangements might ordinarily fall within the word facilities, the contract was expressed to be contingent on the permits and licence extension being obtained before the vessel departed for Cameroon. The parties therefore did not objectively intend the standby clause to cover delay in obtaining those matters. The invoice-dispute machinery regulated billing mechanics and did not create an independent entitlement to charges.
3. Estoppel by convention. The required elements were a clear assumption of fact or law, manifested assent, actual reliance, subsequent mutual dealing, injustice or unconscionability, and an assumption of responsibility for the reliance. Tower Cameroon’s correspondence, reports and conduct did not clearly accept legal responsibility for standby costs. Geoquip also failed to establish sufficient detrimental reliance. The estoppel claim therefore failed.
4. Estoppel by contract. The extension agreement recorded standby hours but did not state that Tower Cameroon was legally liable for them. The recitals did not create a contractual estoppel or alter the proper construction of the agreement.
5. Guarantee and disposition. The extension agreement did not discharge Tower plc’s guarantee. Tower plc had signed the original contract, its chairman signed the extension for Tower Cameroon, and clause 28.6 permitted the principal parties to amend the contract in writing. Judgment was therefore entered for Geoquip for US$610,091.68, its standby-cost claim was dismissed, and Tower plc remained liable as guarantor.
