Tugboat Danum 61 requires comprehensive afloat repair, mechanical refurbishment and restoration of key vessel systems to return the vessel to safe and reliable operational service. UNDP is supporting the procurement and implementation of the rehabilitation works. The scope includes overhaul and repair of major propulsion and auxiliary machinery, underwater and hull-related works, piping and safety systems, navigation/electrical systems, testing, sea trials and final handover. Given the technical complexity of the works and the need for independent verification of contractor performance, UNDP requires a qualified Marine Project Supervision Consultant to provide technical supervision, quality assurance and progress verification throughout procurement and implementation, including any post-completion or defects follow-up falling within the six-month assignment period. Objective of the Assignment The objective of the assignment is to provide independent and professional marine engineering and technical support to UNDP throughout the procurement and implementation stages of the rehabilitation of Tugboat Danum 61, within the six-month assignment period. The Consultant will support preparation and review of technical requirements, procurement-stage technical inputs when requested, field supervision, quality assurance, progress monitoring, testing and handover activities, ensuring that the works are undertaken in accordance with approved contract documents, technical specifications, applicable marine standards, manufacturer requirements, agreed schedules, and health, safety and environmental requirements. The Consultant will inspect, verify, document and technically certify completed works and milestones and will provide UNDP with clear recommendations for acceptance, corrective action, testing, provisional completion and final completion. All contractual decisions and payment approvals remain with UNDP. Scope of Work and Responsibilities The Consultant shall provide technical support across the procurement, implementation, testing and handover stages, and any post-completion/defects follow-up falling within the six-month assignment period, as requested by UNDP, including the following: Procurement Preparation and Tender Support During the first month of the assignment, and thereafter as required until contract award, provide technical inputs to UNDP for the preparation and finalization of the procurement package for the vessel rehabilitation, including review and refinement of the scope of work, technical specifications, equipment/spare-parts requirements, drawings, schedules, inspection/testing requirements, acceptance criteria and other technical documentation as requested by UNDP. Review available vessel records, previous assessments, equipment data, OEM information and site conditions, and identify technical gaps, inconsistencies, ambiguities or missing information that could affect competitive bidding, implementation, testing or acceptance of the works. Coordinate with UNDP and relevant YASPC/Mukalla Port technical representatives to validate technical information and operational requirements, reconcile conflicting or incomplete technical inputs, and ensure that the final requirements are clear, internally consistent and sufficiently detailed for procurement purposes. Any material differences, concerns, assumptions or unresolved technical matters raised by stakeholders shall be documented and referred to UNDP for decision. Support UNDP during the solicitation process by participating, when requested, in pre-bid/site visits or technical meetings and by preparing or reviewing technical responses to clarification requests received from prospective bidders. All communications with bidders shall be issued through UNDPs authorized procurement channels. Support UNDP in reviewing proposed technical alternatives, substitutions or equivalent solutions submitted during the solicitation process and provide documented technical recommendations against the published requirements, without changing the solicitation requirements unless formally approved and communicated by UNDP. Participate in the technical evaluation of offers as a technical evaluator or technical resource to the UNDP-appointed evaluation panel, when formally designated by UNDP. The Consultant shall assess submissions only against the published evaluation criteria and tender requirements, document the technical basis of findings, and comply with applicable confidentiality, impartiality and conflict-of-interest requirements. Provide technical continuity between procurement and implementation by maintaining a clear record of final technical requirements, bidder clarifications and accepted technical interpretations for use during contract implementation, while ensuring that no bidder receives information or access outside the formal UNDP procurement process. Mobilization, Contract Review and Work Planning Following contract award, review the signed works contract, final technical specifications, drawings, bill of quantities/schedules, contractor methodology, implementation schedule, inspection and test plans, HSE documentation, agreed clarifications and relevant OEM requirements. Participate in the joint site handover/kick-off process and establish a practical supervision, inspection, reporting and document-control arrangement with UNDP, YASPC and the contractor. Prepare an inception/supervision note identifying critical technical interfaces, hold points, key risks, required inspections/tests, documentation requirements and the proposed supervision approach for implementation. Mechanical, Electrical and Marine Works Supervision Supervise dismantling, condition assessment, overhaul, repair, reassembly and commissioning of the main engines, auxiliary generators, gearboxes, pumps and associated systems included in the rehabilitation scope. Review dimensional checks, NDT results, inspection findings and repair recommendations against applicable OEM tolerances and approved technical requirements. Inspect and verify materials, spare parts and equipment delivered for the works, including identification, quantity, technical conformity, condition and supporting documentation, and maintain inspection/acceptance records. Supervise installation, integration and testing of piping, fuel treatment/filtration, oily-water separation, fire-fighting, navigation, control, electrical and other systems included in the contract. Witness and document underwater inspections and works, including hull cleaning, anode replacement and underwater welding, using available dive reports, photographic/video evidence and approved procedures. Identify non-conformities, incomplete works or deviations from approved requirements and recommend corrective actions to UNDP. Quality Assurance, HSE and Progress Monitoring Monitor contractor compliance with approved quality-control procedures, method statements, inspection/test plans and applicable marine HSE requirements, including hot works, confined-space activities and diving operations. Monitor progress against the approved programme, identify delays or critical-path risks, and recommend practical mitigation measures to UNDP. Maintain concise site records, inspection notes, photographic evidence, issue/non-conformity logs and risk/action trackers. Submit a concise monthly progress report covering activities performed during the reporting period. During the procurement stage, the report shall summarize technical inputs provided to the procurement package, site/pre-bid support, clarification support, evaluation activities (where applicable), key technical issues and decisions requiring UNDP action. During implementation, it shall cover progress achieved, inspections/tests witnessed, key findings, non-conformities, risks, actions required, and the Consultants level of effort. Significant safety, quality, procurement-integrity, schedule or contractual risks shall be reported to UNDP immediately and shall not wait for the monthly report. Testing, Sea Trials and Handover Witness and verify quayside/static testing of machinery, generators, switchboards, pumps and associated systems prior to sea trials. Review and agree with UNDP and the contractor the readiness checklist and test protocol for sea trials. Witness the approved sea-trial programme, including warm-up, sustained load/full-power testing as applicable, maneuvering and emergency/functional tests, and record results and deficiencies.
