A machinery work list is easier to review when each request identifies a particular unit, the reason for the work and the decision still needed. For a yard stay, distinguish planned maintenance from an unresolved fault before grouping the jobs into one engine-repair enquiry.

Gisan Shipyard’s machinery services include main and auxiliary engines, pumps, and hydraulic and pneumatic equipment. This guide focuses on preparing information for those machinery items.

Identify each engine and its onboard function

Give the main engine and each auxiliary engine a separate equipment reference. Use the vessel’s own labels so that drawings, reports and parts lists point to the same unit. For an auxiliary generating set, distinguish the engine item from an alternator or electrical item rather than treating the set name as a complete repair scope.

  • Vessel name and IMO number, where available, followed by the machinery location and onboard equipment tag.
  • Maker, model and legible serial or engine number from the existing records or nameplate.
  • The unit’s onboard function and the particular components included in the request.
  • Available operating-hour records, with their date and the source of the figures.
  • Photographs already available, including a readable nameplate image if one exists.

Keep a missing or conflicting identity field open for clarification. Equipment identity helps locate the relevant documentation; it does not establish a service provider’s authorization for that maker or model.

Separate planned jobs from faults awaiting investigation

For planned maintenance, reference the existing maintenance task, previous service report or owner-issued work instruction. State the requested job and the components involved. If the planned-maintenance-system record gives a due date or operating-hour basis, retain that reference without turning it into a general maintenance interval.

For unresolved repair items, describe the observation and its history: when it was recorded, which unit was affected, the operating circumstances already documented and any inspection or troubleshooting previously undertaken. Attach existing alarm or trend records when relevant. Keep the observation separate from a confirmed diagnosis.

Label the work list as planned work, a request for inspection or technical assessment, or an option awaiting a decision. A description such as “engine overhaul” needs a component boundary and supporting instruction or finding. It should not become the assumed answer to an unexplained fault.

Connect machinery records to individual work items

Use a consistent item reference across the job list and attachments. A previous report for one auxiliary engine should not be applied to another unit without explanation. Identify drawing numbers and revisions, report dates, component references and any known modifications.

Provide the existing maker documentation relevant to the requested work, where available. Record what is missing or subject to confirmation. Ask which technical instruction will govern an agreed item and who will resolve conflicting records. The initial enquiry should communicate existing information, not create an overhaul procedure or acceptance limit.

Describe pumps and associated machinery as separate items

An engine job may share access or system interfaces with other equipment. List a pump, cooler, heater, separator, turbocharger or governor as its own requested item when work on it is being considered. State whether it is connected to the engine request or is an independent job.

For pumps and hydraulic or pneumatic equipment, identify the unit and its system connection, the condition already recorded, the requested intervention and available drawings or reports. Preserve existing component and connection references. Describe a symptom without assuming a replacement specification, setting or test value.

Keep the pump or machinery item distinct from connected pipe and valve work. Where a request includes an electric motor or other electrical equipment, separate that item and discuss the relevant electrical services scope. A machinery enquiry should not silently assign every adjacent discipline to the same party.

Make spare-parts assumptions visible

Attach an available parts list against the relevant machinery item, using the existing part numbers and revisions. Identify whether each entry is an owner-proposed supply, a request for the yard to quote, or an unresolved supply question.

  • What parts are already available, and what evidence identifies them for this unit?
  • Which quantities or component references remain unconfirmed?
  • Who will confirm suitability and any proposed substitution?
  • Who is expected to procure, receive and check the parts?
  • Are there known delivery constraints or items awaiting an OEM response?

Keep parts availability and the scope decision separate. Having a spare on board does not prove that its use, compatibility or installation has been agreed. Do not assume that procurement or maker support is included in the repair request.

Show access and dependencies within the yard period

Use existing photographs or sketches to identify the equipment location and known access constraints. If removal is being considered, flag the proposed route and any adjacent work that may affect it. Ask who will establish the removal and lifting arrangements; a photograph is not a lifting plan.

Record known operating restrictions, other scheduled work and owner requirements that may affect equipment availability. Ask how machinery items would be sequenced with those constraints. Isolation, safe access and execution arrangements require a separate agreed plan rather than assumptions in the quotation list.

Clarify owner, yard and OEM responsibilities

For each work item, ask who is expected to provide the technical instruction, carry out the agreed work, supply parts and answer maker-specific questions. If OEM attendance or advice is proposed, identify the requested involvement and its current confirmation status.

State any inspection, testing or completion records the owner is requesting, together with the existing requirement behind them. Ask who will perform, review or witness each activity and whether it is included in the proposed scope. This enquiry does not assign class or OEM authority, test parameters or acceptance criteria.

Assemble a focused machinery enquiry

Bring together the equipment schedule, referenced work list, condition and maintenance records, parts questions, access information and preferred yard window. For vessel-level information and the wider repair package, use the ship repair RFQ preparation guide. Keep the machinery list specific to engines and associated equipment; propeller, shaft and rudder jobs need their own component scope.

Share the machinery particulars, available findings and planned yard window through Gisan Shipyard's contact page. Mark missing information and responsibility questions so the first discussion can address the actual units and requested work.
