Capabilities

Surveying the working waters of the Gulf Coast.

From quiet barge fleets on the Sabine to deep-draft vessels calling Port Arthur, our surveyors document tonnage that holds up under underwriter review.

Draft Surveys

Initial and final draft readings, density sampling, ballast soundings, and constant verification — issued with full calculation worksheet.

What it is

A draft survey measures how deep a vessel sits in the water before and after cargo operations. The change in displacement, corrected for water density and onboard liquids, gives a precise cargo weight without ever weighing the cargo itself.

How we do it
  • Read forward, midship, and aft drafts on both port and starboard
  • Sample dockside water density with a calibrated hydrometer
  • Sound all ballast, fuel, fresh-water and diesel tanks
  • Apply hydrostatic tables and density correction
When you need it

Required at every load and discharge port for bulk and breakbulk cargoes — and a standard condition of most cargo and hull insurance policies.

Reported to the industry-standard tolerance of ±0.5% of cargo weight.

Bunker Surveys

On-hire and off-hire bunker quantity surveys — HFO, LSMGO, ULSFO and MGO measured and documented with full ROB statements.

What it is

A bunker survey determines the precise quantity of fuel oil, diesel oil, and lubricants remaining on board at a specific point in time. Measurements are corrected for temperature and density to produce an accurate mass figure for contractual and operational purposes.

How we do it
  • Sound all fuel oil and diesel oil tanks using calibrated tape and paste
  • Record fuel temperatures and apply density correction from lab certificates
  • Sample and verify fuel grade against bunker delivery note
  • Compile a signed ROB statement with calculations and supporting photographs
When you need it

Required at on-hire and off-hire of every time charter; before and after bunkering operations; and whenever an underwriter or charter party requires independent fuel verification.

Industry-standard measurement with temperature and density correction applied.

On/Off Hire Condition

Pre-charter and redelivery condition surveys aligned to BIMCO clauses and underwriter requirements.

What it is

When a charterer takes delivery of a vessel ("on-hire") or returns it ("off-hire"), an independent surveyor documents bunker quantities, hold/tank condition, and any pre-existing damage. The report becomes the contractual baseline for that voyage.

How we do it
  • Joint inspection with master, charterer and owner reps
  • ROB bunker measurement on every fuel grade
  • Photographic record of holds, hatches, and lashings
  • Statement of facts and condition certificate issued same-day
When you need it

At delivery and redelivery of every time charter; before any bareboat handover; whenever an underwriter requires a baseline.

BIMCO-clause aligned, accepted by major underwriters.

Loadmaster

On-site cargo loading coordination and stowage planning to maximize safe tonnage and vessel stability.

What it is

A loadmaster directs the safe and efficient loading of bulk cargo, ensuring proper weight distribution, trim, and stability while maximizing cargo intake within regulatory limits.

How we do it
  • Review vessel stability booklet and loading manual before operations
  • Coordinate with terminal operators on loading sequence and trimming plan
  • Monitor cargo distribution across holds to maintain acceptable GM and draft limits
  • Verify securing and lashing of project or breakbulk cargoes
When you need it

Required when loading bulk or breakbulk cargoes where proper weight distribution is critical to voyage safety — especially deep-draft vessels or uneven cargo parcels.

Stability-compliant loading within class-approved limits.

Supervise Loading

Independent attendance during cargo operations — tallying cargo and observing, documenting and reporting loading and discharge operations to assure your cargo is handled properly.

What it is

Loading supervision ensures cargo is handled, stowed, and documented according to the contract of carriage, charter party, and letter of credit requirements. Our surveyors witness each stage — tallying cargo, observing operations, and documenting conditions — then issue a statement of facts.

How we do it
  • Attend pre-loading hold inspection and document condition
  • Tally cargo and observe loading or discharge operations, documenting every stage
  • Monitor for damage, contamination, or non-conforming cargo
  • Report findings and issue statement of facts and tally certificates with time logs
When you need it

Required when the shipper, charterer, or receiver needs independent verification that cargo was loaded in apparent good order and condition — standard for letters of credit and insurance-backed shipments.

Independent attendance with same-day statement of facts.

Cargo Sampling & Lab Transport

Representative cargo sampling followed by chain-of-custody transport to the laboratory of your choice — or we can recommend one.

What it is

We collect representative samples of bulk cargo during loading or discharge, seal them under witnessed chain-of-custody, and transport to a certified laboratory for testing — either your designated lab or one we source for you.

How we do it
  • Determine sampling plan based on cargo type, parcel size, and contract specs
  • Collect samples during loading or discharge using approved equipment and methods
  • Seal, label, and document chain-of-custody under joint witness
  • Coordinate transport to local or third-party lab and track delivery confirmation
When you need it

Required when cargo quality must be verified against contract specifications — moisture, sulfur content, ash, HGI, or any cargo-specific assay.

ASTM/ISO-compliant sampling with documented chain-of-custody.
Core Materials

The materials we know best

While we survey a wide range of bulk cargoes across the Gulf Coast, the majority of our experience is concentrated in these materials:

Green Petroleum CokeCalcined Petroleum CokeAnodes (Green and Calcined Baked)Coiled Wire RodPig IronOther Scrap Metals

We are eager to learn new industries so we can provide services for the movement of any dry bulk materials by ship or barge.
