Guidance Information
1Definition
Workplace policies andproceduresrefers to the documented procedures and policies providing guidelines of the tasks and activities carried out in the workplace. This typically includes relevant health and safety policies to manage risk in the workplace.
2Evidence of the performance criteriaof this unit standard must be presented across the following contexts:
apower plant components – the engine (petrol or diesel) and its subframe, plus ancillary equipment and systems, (including water jacketed manifolds and exhaust system including waterlocks, mufflers, anti-syphon devices, lagging, securing devices, and instrumentation), cooling system (including controls, valves, plumps, skin fittings, filters, condensers, heat exchangers, and intercoolers, and securing devices), raw water pumps, charging systems, drives (hydraulic and electric), refrigeration system, engine controls and instrumentation, steering system (mechanical, hydraulic, and electronic), fuel system (including filters, pumps, controls, tankage, pipework, securing devices, and instrumentation), and ventilation system (including water traps, water locks, and securing devices);
evidence is required for an engine plus eight other items.
bpower train components – includes flywheel damper, clutch, gearbox (mechanical and hydraulic reverse production), damper assemblies, propeller shaft, and propulsion device (propeller, jet unit, or surface drive) drive lines (flexible and rigid), bearings, rawwater seals, struts, couplings, constant velocity joints, universal joints;
evidence is required for a gearbox plus six other items.
3All work practices must meet recognised codes of practice and workplace policies and procedures (where these exceed code) for personal, product, and workplace health and safety, and must meet the obligations required under the Health and Safety at Work Act 2015 and Resource Management Act 1991, and any subsequent amendments.
Outcomes and performance criteria
Outcome 1
Analyse motive power requirements for specific boats.
Rangeyachts, launches, power boats, surveyed craft.
Performance criteria
1.1Analysis of customer’s requirements establishes the expected price range and expectations of product performance.
1.2Analysis of existing, supplied, and proposed components establishes their suitability to meet customer’s requirements.
Rangecustomer’s requirements – performance, operating environment, insurance requirements, warranty requirements, noise, vibration, fuel usage (including fuel economy).
1.3Analysis of boat type and intended end use identifies applicable regulatory and survey requirements.
1.4Analysis of boat structure establishes the viability of achieving customer’s requirements for motive power without compromising boat safety and/or compromising customer’s requirements for boat usage.
Outcome 2
Produce specifications to meet motive power requirements.
Performance criteria
2.1Specifications are matched with customer’s, regulatory, and survey requirements.
2.2Specifications are matched with existing components and boat structure.
2.3Terminology used meets the requirements of users.
Outcome 3
Select components to match motive power requirements.
Performance criteria
3.1Selected components meet customer’s, regulatory, and survey requirements.
3.2Selected components are available within customer’s time and cost requirements.
3.3Customer acceptance that the selected components meet their requirements is documented in accordance with workplace policies andprocedures.
