Overview: This guide explains how to collect, label, and prepare ship samples for analysis, following the workflow from initiation to analytical preparation.

\n

Initiation

\n
    \n
  1. Collect the Port Time Sheet for information.
    2. \n
  2. Initiate ship in ODS, including details: Shipment, Shipment Analysis worksheet.
    3. \n
  3. Print the Mate’s Receipt and Stowage Plan. These are emailed to the site by Wilhelmsen Ships Service Pty Ltd in Geraldton.

Sample Preparation

\n

Note: Expect around 5-7 buckets of sample, one for each hatch loaded.

\n
    \n
  1. Label each bag with the ship number, ship name, B/L date and hatch number found on the bucket.
    2. \n
  2. Weigh each sample bag on the industrial top loading balance and record weight to 1 g.
    3. \n
  3. Split each bag using the riffle splitter. Split the sample down to the mass for that hatch as defined by the “Expected Sample Weight”. This will generate a total composite sample of 7 kg.
    4. \n
  4. Mix/Homogenise the composite sample by mixing it thoroughly on the bench.
    5. \n
  5. Split the composite sample with the riffle splitter for the following:\n
      \n
    • Reference ship composite - place 2 kg of uncrushed composite sample into a 2 L plastic container. Label with ship name, LM number, B/L date and Tonnes. Store in the sample storage room. All samples must be kept until the annual composite sample is collected.
      • \n
    • Particle Size Analysis – place approx. 500 g of uncrushed composite sample into a snap lock bag. Label it with a ship name, LM number, B/L date, and ‘Particle Size Analysis.’
      • \n
    • Colour Analysis - place approx. 500 g of uncrushed composite sample into a snap lock bag. Label it with a ship name, LM number, B/L date, and ‘Colour Analysis.’
      • \n
    \n
    6. \n
  6. Analytical Analysis samples (A&B) – In duplicate, crush approximately 1 kg of composite sample in the heavy-duty blender to achieve particle sizing of less than 2 mm. Place both samples in labelled plastic bags and seal them to prevent moisture loss. Processing of the moisture determination shall proceed without delay.

Analytical Preparation

\n
    \n
  1. Weigh 25.00 g +/- 0.01 g in duplicate for each sample into 250 mL volumetric flasks. Label the flasks A1, A2, B1, B2. Place the flasks on the flask shaker until all salt has dissolved,
