# Complete steel-hulled diesel general cargo vessel manufacturing

## 1. Scope and Applicability

Manufacture of complete new steel-hulled dry general cargo vessels with mechanical diesel propulsion and a declared fixed-pitch propeller: hull-section fabrication and erection, actual surface finishing, purchased propulsion/piping integration, cargo-hold closures and ship outfit integration, launching, harbour/sea acceptance trials and net-mass acceptance. Select one actual hull number, released design and delivery configuration. This is a narrower methodology than CPC49314.

Exclude tankers, container-only ships, ro-ro/passenger ships, self-discharging ships, unpowered barges, fishing/work/naval vessels, LNG/hybrid/electric propulsion, separately sold hulls/parts, repair and remanufacture. Cargo/passengers, commercial voyages, tonne-km, use-stage bunkering, maintenance, demolition and port service infrastructure are outside manufacture. Actual construction transfer/tow and acceptance trials are manufacturing support and require explicitly bounded measured modules; no service life or cargo-performance equivalence is assumed.

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Actual supplier ship plates/profiles and released bought-in marine propulsion/outfit received at declared yards. Rolling, engine/propeller manufacture and utilities are upstream unless explicit measured site modules; declare supplier cut/form/coating state. |
| starting_condition_role | foreground_manufacturing_module |
| product_classification_scope | Manufacture of complete new steel-hulled dry general cargo vessels with mechanical diesel propulsion and a declared fixed-pitch propeller: hull-section fabrication and erection, actual surface finishing, purchased propulsion/piping integration, cargo-hold closures and ship outfit integration, launching, harbour/sea acceptance trials and net-mass acceptance. Select one actual hull number, released design and delivery configuration. This is a narrower methodology than CPC49314. |
| recursive_input_rule | Same-category purchased complete ship cannot replace a hull-block input or generate recursive full-ship manufacture. Purchased blocks/equipment replace contained site material/work. Internal block/system transfers counted once; receipt and supplier-boundary scope govern. |
| upstream_dataset_requirement | Expanded assessment requires compatible actual steel, chemicals, propulsion/outfit, utility, outsourced finish, inbound/interyard transport/tow and waste treatment datasets with provider/version/coverage; this foreground alone is not complete cradle-to-gate. |
| disclosure | hull number/model; approved released drawings and revision; hull plate/section grades and certificates, thickness and make-or-buy; hold/tween-deck/hatch design and fitted cargo gear; marine engine supplier/model/count and independent measured mass, gearbox/shaft/propeller scope; generator/pump/pipe/valve supplier containment; electrical voltage/cable and radar configuration; safety, accommodation and insulation fit list; actual coating formulation/route; yard/sites, intersite tow, period and accepted count; current vessel-specific lightweight survey and hydrostatic/reference-position evidence; controlled acceptance net M and corrections; empty cargo/tank delivery state; retained technical oil/coolant versus excluded bunkers/ballast/stores; supplier prefill scope; survey/test instruments and uncertainty; upstream utilities/transport/treatment coverage |

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| boundary_configuration | finished_machine | Restrict the complete ship to the declared steel-hull dry general cargo, mechanical marine diesel and fixed-pitch configuration. Damen case architecture supports cargo-hold and propulsion specificity, not a universal size, power, cargo rating or efficiency factor. Actual current released drawings govern; optional hybrid/battery/biodiesel routes are excluded here. | damen-cf5000 |
| boundary_manufacture | manufacturing | Actual fabrication, finishing, outfitting, launch support and acceptance trials/rework are included where performed. Process sequence is site-specific: supplier-cut stock, outsourced blocks/finish and pre/post-launch fitting must be declared. Each alternative operation needs its own physical exchanges, not a placeholder collection. | bodewes-build |
| boundary_trials | trials | Include actual trial fuel and measured emissions only within declared trial start/end/loads and manufacturing transfer/tow support. Independent contracted tug service has measured trip/time, endpoints, actual provider and fuel/utility coverage; do not duplicate its fuel in vessel trials. No commercial service inventory or assumed full-load tanks. | bodewes-build |
| boundary_water | sea_resource | Direct seawater resource intake is distinct from purchased municipal water. For actual cooling/ballast trials, reconcile measured withdrawals, retention and returns at recorded salinity/temperature; specify actual return medium/composition and thermal state in separate exchanges. Product-type seawater candidates do not establish an elementary resource. Oily bilge treatment and its evidenced final discharges are separate. |  |

## 7. Allocation and Co-product Handling

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| allocation_causal | shared_operations | First subdivide yard/work orders by hull, design and stage. Shared cutting, welding, blast/paint, lifting and dock/shore trial utilities use exchange-specific actual measured causal load/time or demand from cp_allocation, reconciled to supplied total and excluded work. No default deadweight, GT, engine power or hull-area shares. |  |
| allocation_variants | hulls | Each hull configuration retains its own measured M and numerator. Rework/reject burden attributed to accepted construction; pooled results only after separate normalization with disclosed measured weights. Residual physical/economic fallback needs actual causal records, sensitivity and review, not invented percentages. |  |
| allocation_recovery | outputs | Recovered shot/flux/steel/water within yard are transfers, not automatic coproduct or avoided-production credits. External scrap/waste retains measured condition, treatment and responsibility. Saleable coproduct claims require actual quality/market records and reviewed handling; no future ship-recycling credit. |  |

| cp_machinery | machinery | each atomic process row | measurement | supplier part/model; engine actual count and independent measured dry/installed mass; scope/mass of gearbox/shaft/propeller/genset/pump/pipe/valve; prefill list; alignment and installation records; electricity | Count actual supplied assembled marine engines in Item(s), preserving the public property; independently weigh or obtain traceable actual engine weighing records for complete vessel mass reconciliation. Measure each other part supply and separately added fluid, reconcile contained versus installed configuration to hull-specific BOM. | kg; MJ; Item(s) | each hull/work order; stock/meter closure each reporting period | whole declared construction cycle including rework; accepted hull count matched | all actually included yards/outsourced operations | attributable exchange amount / accepted units | calibration; supplier fit-list; work orders; issue/return and acceptance records; missing-data log |
| cp_outfit | outfit | each atomic process row | measurement | hatch/steering/closure model and mass; actual insulation/facing; cable specification/mass; board voltage/inclusions; radar scope; safety/accommodation fit-list with measured masses; electricity | Measure each actual released installed part supply; split different product specifications and remove duplicates contained in bought-in modules.

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| normalize_mass | hull_plate; hull_profile; weld_wire; weld_flux; hull_power; steel_scrap; weld_slag; particle_air; blast_shot; epoxy_primer; antifoul_coat; finish_water; finish_power; spent_shot; paint_residue; xylene_air; diesel_engine; reduction_gear; propeller_shaft; propeller; diesel_genset; ballast_pump; steel_pipe; butterfly_valve; machinery_power; hatch_cover; steering_gear; watertight_door; insulation; copper_cable; switchboard; navigation_radar; outfit_power; trial_fuel; engine_oil; trial_water; sea_resource; trial_power; used_oil; oily_bilge; fossil_co2_air; nitric_oxide_air | q_ref = q_item / M; q_item = exchange amount per one accepted finished unit; q_ref = exchange amount per 1 kg reference flow. | q_item; M; cp_mass | q_ref |  |

q_item is attributable actual same-hull/configuration exchange after issue/return, stock, waste/recovery and rework reconciliation divided by matched accepted units. Preserve each numerator kg, MJ or engine Item(s); separate independently measured component mass closes the vessel fit-list, never numerically add engine count to kg. Any volume/density, installed part count/mass or concentration/formulated-mass conversion requires actual same-product/state measurements and declared uncertainty; no assumed density or catalogue weight. The survey-to-net M derivation is a separate physical evidence rule below, not an additional algebraic clause in normalize_mass.

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| quality_survey | finished_machine | cp_mass acceptance records must originate in a current actual vessel lightweight/weight survey by a qualified responsible party. Retain original dated hull-specific draft/freeboard positions/readings and repeat checks, water density, verified reference geometry and hydrostatic model at actual trim/heel/deformation conditions, inspected/sounded tank contents and measured add/remove items. Retain traceable instruments, calculation/software/version, signatures and propagated uncertainty; reconcile to complete released fit-list and independent weighed stock/component balance. A displacement figure alone is insufficient. The NMA2020 example supports this method architecture only, not current statutory compliance or numeric thresholds. Missing physical survey/correction evidence blocks dataset use. | nma-lightship-2020 |
| quality_delivery_mass | finished_machine | Survey lightship condition and PCR net delivered condition must be explicitly reconciled. Include actual installed hull/outfit and declared retained technical oil/coolant in M once; exclude cargo/persons, bunkers, ballast, stores, temporary staging/test weights, packaging and detached spares. Document each correction from actual measured quantities/state, complete missing fit items before final acceptance or independently verify their measured installed mass. Fuel full-load mass, deadweight, gross/net tonnage, design/catalogue lightship estimates and residual guessed mass cannot replace M. No whole-vessel platform scale is presumed. | current survey; signed delivery correction; independent measured fit-list |
| quality_prefill | components | Independently measured engine dry/installed masses and received module-contained prefill must reconcile to whole-vessel M. Separately issued oil/coolant counted only beyond supplier-contained fill; trial consumption/removed fluids and retained technical fill separated. No lubricating oil added twice through engine and trials; generator package engine not duplicated as propulsion engine. | supplier scope; weighing/fill records; hull BOM |
| quality_identity | flows | Require actual grades, chemical/formulated supply, route/state and supplier-contained part scopes; preserve public reference property. Particle/xylene/fossilCO2/NO need actual immediate-air submedium/species evidence; direct seawater resource separate from product water and oily wastewater. No unmeasured default fuel carbon/sulfur, emissions or lifetimes. | supplier certificates/SDS; outlet samples and calibration; identity audit |
| quality_acceptance | trials | Retain current hull/weld inspection, watertight/pressure-system, alignment, steering/electrical/safety and actual harbour/sea trial acceptance records as required by released design. Actual authority/class approvals when held must be traceable; manufacturer marketing cannot establish compliance, numerical pass limits or universal test load. | released vessel plan; actual survey/test approvals; bodewes-build |
| quality_coverage | dataset | Declare actual measured/calculated/estimated/missing/excluded/not-applicable states for every fit-list and route exchange; expand atomic rows for all actual equipment/chemicals/emissions and purchased tow/treatment services. Record primary coverage, uncertainty, provider versions and gaps. Sources supply architecture, not complete plant LCI. | work orders; meter/stock closure; complete fit-list; coverage register |

## 9. Validation Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| validation_reference | finished_machine | Require1kg complete accepted output and same-hull controlled net M with quality_survey and quality_delivery_mass physical evidence. Do not accept a scale fiction, catalogue/deadweight/tonnage or displacement-only proxy. The finite measurement check validates declared q_item/M relation, not actual survey adequacy. | nma-lightship-2020 |
| validation_basis | inventory | Match accepted hull count, construction period, configuration and numerator units to normalize_mass and declared protocol. Engine Item(s) needs separate independent mass reconciliation; do not overwrite property or make power-to-mass assumptions. |  |
| validation_modules | manufacturing | Audit supplier blocks, propulsion/generator/outfit containment and prefill against installed BOM; actual missing outfit and alternative finish/joining/support routes require separate atomic inventories. Check trial versus commercial-operation scope and external tow/fuel duplication. |  |
| validation_releases | elementary | Verify species/CAS and actual medium/submedium/time after controls. NO is not total NOx as NO2 or N2O; fossilCO2 requires measured fossil origin. Size fractions replace unspecified duplicates. Clean seawater return, thermal exchange, treated effluent and actual pollutants individually evidenced, never assume all as oily bilge or marine emissions. |  |
| validation_completeness | dataset | Keep identity and physical-data gaps explicit. Complete actual survey/correction, production records, fit-list, supplier/transport/utilities/treatment coverage and applicable acceptance before use. Structural check pass does not grant scientific approval or full cradle-to-gate coverage. |  |

## 10. Published Dataset Profile

| Field | Value |
| --- | --- |
| dataset_role | foreground_manufacturing_module |
| downstream_use | secondary_dataset; background_dataset |
| allowed_use | Manufacture of complete new steel-hulled dry general cargo vessels with mechanical diesel propulsion and a declared fixed-pitch propeller: hull-section fabrication and erection, actual surface finishing, purchased propulsion/piping integration, cargo-hold closures and ship outfit integration, launching, harbour/sea acceptance trials and net-mass acceptance. Select one actual hull number, released design and delivery configuration. This is a narrower methodology than CPC49314. |
| excluded_use | Exclude tankers, container-only ships, ro-ro/passenger ships, self-discharging ships, unpowered barges, fishing/work/naval vessels, LNG/hybrid/electric propulsion, separately sold hulls/parts, repair and remanufacture. Cargo/passengers, commercial voyages, tonne-km, use-stage bunkering, maintenance, demolition and port service infrastructure are outside manufacture. Actual construction transfer/tow and acceptance trials are manufacturing support and require explicitly bounded measured modules; no service life or cargo-performance equivalence is assumed. |
| required_metadata | hull number/model; approved released drawings and revision; hull plate/section grades and certificates, thickness and make-or-buy; hold/tween-deck/hatch design and fitted cargo gear; marine engine supplier/model/count and independent measured mass, gearbox/shaft/propeller scope; generator/pump/pipe/valve supplier containment; electrical voltage/cable and radar configuration; safety, accommodation and insulation fit list; actual coating formulation/route; yard/sites, intersite tow, period and accepted count; current vessel-specific lightweight survey and hydrostatic/reference-position evidence; controlled acceptance net M and corrections; empty cargo/tank delivery state; retained technical oil/coolant versus excluded bunkers/ballast/stores; supplier prefill scope; survey/test instruments and uncertainty; upstream utilities/transport/treatment coverage |
| required_quality_disclosure | Current released design, supplier containment and fit-list; survey original method/readings/calculation/version/uncertainty; corrected net M and delivery fluids; engine count and independent actual mass; yard/period/trial/rework/stock balance; actual missing exchanges and provider/upstream/tow/treatment gaps; allocation sensitivity; unresolved identities; evidence limitations and scientific review state. |
| update_trigger | Hull/design/plate grade, propulsion or cargo/outfit configuration, supplier/make-or-buy/coating route, yard/utility/trial method or period, survey/delivery state, physical evidence or identity resolution changes. |
