TOEIC Link Vocabulary — Cargo Hold Inspection and Hatch Cover Weathertightness Survey Cluster

Cargo hold and hatch cover condition is one of the most inspection-heavy areas of a dry-cargo ship, and the correspondence it generates — condition reports, class recommendations, pre-loading survey certificates, and off-hire dispute letters — recycles a compact vocabulary with unusual consistency. A surveyor who can read a hold coating breakdown grade or a compression bar deformation note at speed is reading the same lexical field the TOEIC Link reading section samples when it builds workplace passages around inspection, maintenance, and reporting. This cluster gathers the 60 highest-frequency terms into six functional groups, each with the collocations that actually appear in survey English and a register note that flags where a word belongs on the formality scale.

Vocabulary in a technical field is not a memorization problem — it is a precision-and-collocation problem, the same discipline described in the vocabulary precision and collocation discipline guide. Learning corrosion in isolation does little; learning that surveyors write advanced corrosion, grooving corrosion, and corrosion allowance — and never big corrosion — is what converts a memorized word into rubric-scoring output.

Group 1 — Hold structure and access

The physical vocabulary of the hold itself anchors every inspection report.

• cargo hold — the primary compartment; collocates hold cleanliness, hold survey, empty hold.
• tank top — the plating that forms the hold floor above the double bottom; tank top plating, tank top damage.
• hopper side and topside tank — the sloped and upper wing structures; hopper plating, topside sloping plating.
• transverse bulkhead and corrugated bulkhead — the divisions between holds; bulkhead corrugation, shedder plate.
• frame and web frame — the stiffening members; side frame, frame bracket, lower stool.
• access ladder and manhole — the entry points; hold access, cargo hold ladder.

Register note: these are neutral technical nouns, appropriate in both spoken briefings and formal reports.

Group 2 — Corrosion and wastage grading

This is the highest-value sub-cluster because it carries the report's core judgment.

• corrosion — collocates general corrosion, localized corrosion, advanced corrosion, grooving corrosion.
• wastage — measured loss of steel thickness; diminution, thickness measurement, gauging.
• pitting — localized pits; scattered pitting, pitting intensity, pit depth.
• corrosion allowance — the margin built into the scantling; within allowance, below the allowable limit.
• substantial corrosion — a class-defined threshold, not a casual adjective; use it only in its technical sense.
• renewal — replacement of wasted steel; steel renewal, cropping and renewal, insert plate.

Register note: substantial corrosion and diminution are formal-tier terms tied to survey standards. See how tier matching works in the tone and register control guide.

Group 3 — Coating condition

Coating grade often predicts the corrosion story, so surveyors report it precisely.

• coating — collocates coating condition, hard coating, coating breakdown.
• breakdown — the graded loss of coating; coating breakdown ratio, edge breakdown.
• The three-tier scale most reports use: GOOD, FAIR, and POOR coating condition — these are terms of art, written in that fixed form.
• blistering, flaking, and peeling — modes of coating failure; blistered coating, flaking paint.
• anode and sacrificial anode — in ballast spaces adjoining the hold; anode wastage, depleted anode.

Group 4 — Hatch cover mechanics

The moving-steel vocabulary of the hatch cover set.

• hatch cover — collocates folding hatch cover, side-rolling hatch cover, pontoon cover.
• coaming — the raised frame the cover seats on; hatch coaming, coaming top plate.
• compression bar — the steel bar that compresses the seal; compression bar wastage, deformed compression bar.
• cleat and wedge — the securing devices; quick-acting cleat, cleat adjustment.
• panel — an individual cover section; panel alignment, panel-to-panel.
• hydraulic — the operating system; hydraulic cylinder, hydraulic ram, oil leakage.

Group 5 — Weathertightness and sealing

The words that decide whether cargo stays dry.

• weathertight — the pass/fail concept; weathertight integrity, maintain weathertightness.
• rubber packing and gasket — the seal itself; packing renewal, permanent set, hardened rubber.
• cross joint and drainage channel — where water is stopped and led away; cross-joint sealing, non-return drain valve.
• hose test, chalk test, and ultrasonic test — the three weathertightness test methods; hose test failed, ultrasonic tightness test.
• ingress — water entry; water ingress, ingress of water into the hold.

Register note: ingress is formal-tier and near-universal in marine reports; the everyday leak appears in speech but rarely in the written finding.

Group 6 — Findings, actions, and reporting verbs

The verbs and outcome nouns that frame every entry.

• note, observe, and record — reporting verbs; it was noted that, the surveyor observed.
• recommend — the class action word; a recommendation was issued, recommendation to be cleared.
• rectify and make good — repair verbs; to be rectified before loading, defects made good.
• satisfactory and defective — outcome adjectives; found satisfactory, defective packing.
• fit to load — the pre-loading conclusion; holds fit to load the intended cargo.

How to drill this cluster for the test

Reading passages in the professional-band TOEIC Link reward readers who process a technical noun phrase as a single chunk rather than word by word. Drill coating breakdown ratio and compression bar wastage as units, not as three separate words. The same chunking discipline that speeds a survey report speeds a test passage, and it pairs directly with the transition and connector work in the transition signal precision guide, because inspection reports link findings to actions with exactly the causal and concessive connectors the writing rubric samples.

Build a weekly routine: take one recent hold or hatch condition report, extract every term that appears in the six groups above, and write two collocations for each from memory before checking. Precision comes from collocation, and collocation comes from repeated, tested exposure — not from a longer word list.

Summary

The cargo hold and hatch cover weathertightness field is compact, repeatable, and high-value: sixty terms in six functional groups cover the overwhelming majority of what a surveyor reads and writes and what a professional-band TOEIC Link passage samples. Learn each term with its collocations and its register tier, chunk the noun phrases, and the vocabulary stops being a list to memorize and becomes a field you read at speed.
