SOLAS Pipefitting study plan

SOLAS Pipefitting · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Safety, Regulations and Code Requirements & Pipe, Fittings, Valves and Materials

  • List the SOLAS chapters and identify which ones drive piping requirements for fire main, bilge, ballast, fuel and steam systems, writing a one-line summary of each relevant chapter.

  • Map at least 15 specific regulatory requirements (fire main pressure and diameter, bilge suction sizing, fuel oil tank fittings, valve material limits) to the system or component they govern in a personal reference sheet.

  • Classify 20 common piping materials (carbon steel, copper-nickel, stainless grades, galvanized steel, GRE/GRP) by typical marine service, corrosion behaviour and where class rules restrict or prohibit them.

  • Identify the function, standard and selection criteria for at least 10 fitting and valve types (gate, globe, butterfly, check, ball, strainer, expansion joint, flanged and welded fittings) and record pressure/temperature ratings.

  • Explain the difference between SOLAS, classification society rules, flag state requirements and IMO codes, and note which takes precedence when they conflict on a piping detail.

Your checkpoint

A 4-6 page personal regulation-and-materials reference sheet with a requirement-to-system mapping table and a 20-material, 10-component selection matrix.

Week 2

Pipe, Fittings, Valves and Materials & Piping Systems and Components

  • Describe the layout, key components and failure points of five shipboard systems: fire main and sprinkler, bilge and ballast, fuel oil transfer and service, compressed air, and steam/condensate.

  • Trace a bilge suction line from strum box to overboard discharge and label every component, valve, non-return device and regulation that applies along the route.

  • Select pipe schedule, wall thickness and pressure class for three worked examples using design pressure, temperature derating and corrosion allowance.

  • Compare valve actuation and end-connection options (flanged, welded, threaded, butt-weld) and justify a choice for a fuel oil isolation valve and a fire main section valve.

  • Explain how system segregation, cross-connection prevention and backflow protection are achieved in bilge, ballast and potable water systems.

Your checkpoint

Five hand-drawn system schematics with annotated component lists, plus three written pipe-sizing calculations showing pressure class and wall thickness selection.

Week 3

Pipe Layout, Measurement and Preparation & Tools, Equipment and Safe Work Practices

  • Perform take-offs from a simple arrangement drawing and produce a cut list of at least 20 pipe spools with sizes, lengths, end preparations and material grades.

  • Calculate true lengths, cut lengths and bend allowances for 90-degree and 45-degree offsets, including two rolling offsets, showing all working.

  • Demonstrate correct use of tape, laser measure, spirit level, plumb bob and angle finder, and record the tolerance you would accept on each measurement.

  • Select and inspect cutting, bevelling and threading tools, and state the inspection criteria for a bevelled end before welding (bevel angle, land, root gap, cleanliness).

  • Write a job hazard analysis for a pipe-cutting and grinding task covering hot work, fume, noise, eye injury and manual handling controls.

Your checkpoint

A measured take-off package for one drawing: cut list of 20+ spools, worked offset calculations and a completed job hazard analysis.

Week 4

Pipe Joining and Fabrication Methods & Tools, Equipment and Safe Work Practices

  • Sequence a butt-weld joint from fit-up to final inspection, naming the standard, consumable and acceptance check at each step.

  • Compare welding, brazing, threaded, flanged, grooved and adhesive-bonded joining methods and state where each is permitted or prohibited in marine piping.

  • Identify at least eight common weld defects (lack of fusion, porosity, undercut, slag inclusion, incomplete penetration, cracking) and their likely causes and prevention measures.

  • Explain preheat, interpass temperature and post-weld heat treatment requirements for carbon steel and stainless steel, and when dissimilar-metal joints need special electrodes.

  • Assemble a safe hot-work permit checklist and describe fire watch, gas-freeing and adjacent-space precautions for welding in a machinery space.

Your checkpoint

A written joining-method selection guide plus a weld-defect cause-and-prevention table and a completed hot-work permit checklist.

Week 5

Pipe Supports, Hangers and Expansion Control & Piping Systems and Components

  • Calculate thermal expansion for three pipe runs using material expansion coefficients and convert results into anchor, guide and expansion-loop requirements.

  • Select support type and spacing for horizontal and vertical runs of at least four pipe sizes, referencing span tables and accounting for valve and fitting weight.

  • Explain how fixed points, sliding supports, spring hangers, guides and expansion joints share load and movement, and identify what goes wrong when each is omitted.

  • Size and position an expansion loop or offset for a given run and temperature change, showing the calculation.

  • Identify vibration, water hammer and settling risks in a supported system and propose a corrective detail for each.

Your checkpoint

A support and expansion calculation package for three pipe runs, including a marked-up sketch showing anchors, guides, supports and loop dimensions.

Week 6

Pressure Testing, Inspection and Quality Control & Safety, Regulations and Code Requirements

  • Write a hydrostatic test procedure for a piping system covering test pressure, hold time, water quality, venting, isolation and acceptance criteria.

  • Explain when hydrostatic testing is replaced by pneumatic or alternative testing, and state the additional safety controls pneumatic testing demands.

  • List non-destructive examination methods (visual, dye penetrant, magnetic particle, radiography, ultrasonic) and match each to the defect type and joint it best detects.

  • Describe the documentation trail for a tested system: test pack contents, pressure gauge calibration, witness signatures, defect records and reinstatement after repair.

  • Link test and inspection requirements back to the SOLAS and class-rule clauses that mandate them, and note surveyor attendance points.

Your checkpoint

A complete hydrostatic test pack template with procedure, NDE selection table, gauge calibration record and sign-off sheet, plus a regulation cross-reference list.

Week 7

Isometric Drawings, Specifications and Documentation & Pipe Layout, Measurement and Preparation

  • Read a piping isometric and extract line number, size, specification break, flow direction, component tags, coordinates and bill of materials.

  • Produce a hand-sketched isometric for a three-run line with two changes of direction, an offset and two valves, correctly using standard symbols.

  • Interpret a piping specification and material take-off, and identify at least five discrepancies or missing data that would stop fabrication.

  • Explain the purpose and content of line lists, weld maps, spool drawings, as-built markups and punch lists, and who signs each.

  • Apply revision control: identify what changed between two drawing revisions and describe how the change flows to the shop floor.

Your checkpoint

A hand-drawn isometric with full bill of materials, plus a written discrepancy report identifying five issues in a supplied specification extract.

Week 8

Safety, Regulations and Code Requirements & Pipe, Fittings, Valves and Materials & Pipe Joining and Fabrication Methods & Pressure Testing, Inspection and Quality Control

  • Complete a timed 60-question mixed mock exam across all nine domains and score each domain separately to expose weak areas.

  • Re-study the two lowest-scoring domains using condensed notes and re-test with 20 targeted questions per domain.

  • Recite from memory the key numeric limits (fire main pressure and diameter, test pressure ratios, support spans, expansion coefficients, weld acceptance limits) without reference.

  • Explain aloud, in under three minutes each, five high-risk topics: fuel oil system fittings, hydrostatic test acceptance, expansion loop sizing, weld defect causes and isometric reading.

  • Build a one-page exam-day sheet of formulas, limits and checklists, and confirm logistics and permitted reference material.

Your checkpoint

Two scored mock exams with a domain-by-domain score log showing improvement, plus a one-page final revision sheet.
