DRAFT SURVEYS & MARINE SERVICES

Draft survey is a means of determining the weight of any materials being loaded into a vessel or discharged from a vessel. Our experienced and highly qualified professionals can conduct draft survey on your behalf and produce an independent draft survey report.

Vessel draft survey measures the displacement of the water both before and after the loading or unloading, with the resulting difference between the two displacements representing the weight of the cargo. Our surveyors work according to defined international guidelines when determining the weight of the cargo and consider several key factors while making their surveys. These factors include:

Water density of the sea, river or other waterway
Changes in the ballast quantity between initial and final draft readings
Changes in the vessel’s consumables (e.g., fuel oil, drinking water) between initial and final draft readings
Trim and deformation corrections (we use data from the vessel’s draft tables)
The accuracy of a weight determined by draft survey also depends upon the sea conditions (pitch and swell) at the time of loading or discharge.

VESSEL HOLD (HATCH) INSPECTION

This inspection is very crucial especially when bulk commodities are transported through vessels. By performing this inspection, both the parties can have the confidence that the cargo will not be contaminated by material that is already in the hold, or affected in any way by vessel defects, etc. Our inspectors photograph, document, and report on any abnormalities they encounter. After completing the assessment, we provide a certificate of inspection.

Hold Inspections Our inspector verifies that the ship’s hold is ready and fit to receive intended cargo. A number of factors are considered when performing hold inspections that may affect the quality of cargo.

Our experienced inspectors:

Ensure that the hold is free from rust, or paint-chips that could contaminate or discolor cargo
Provide assurance that the hold is free of previous cargo remnants, including inaccessible areas
Look for evidence of wooden partitions or dunnage that may react with cargo and may ignite
Examine the ship’s log for evidence of previous cargo containing materials that may put the intended (new) cargo at risk
Pay special attention to previous cargos including seed or grain that may lead to consequences due to quarantine requirements
Check for any signs of moisture or previous water damage in the hold or bilge

Hatch Inspections A high number of cargo defects and rejections occur due to inadequate ship’s hatch cover seals and securing arrangements. Our hatch inspections provide evidence that the condition of the hatch covers does not pose any threat to the cargo.

Our experienced inspectors:

Visually inspect hatch covers at departure and arrival for water tightness and proper operation
Look for obvious damage, holes and leak points that may jeopardize the quality of the cargo
Conduct Chalk, Hose and Ultrasonic Leak Detection (ULD) tests for objective assessment and verification
Complete, independent hatch and hold inspections services offered by us.

BUNKER SURVEY

Bunker Survey, also commonly known as Bunker Delivery Survey, Bunker Quantity Survey (BQS) or Bunker Stem Survey forms a critical part of preventing bunker delivery losses.

Bunker surveyors are mainly engaged to independently check and determine the barge delivered quantity and the vessel received quantity. These two quantities should be within acceptable tolerance (usually 0.5% of received quantity) and if not, the surveyor must investigate the cause of the discrepancy.

In addition to the pre and post transfer meeting and documentation, our bunker surveyor requires to:

Conduct a full initial gauging of all vessel’s tanks and record the actual initial quantity of bunkers on board the vessel.
Compare the actual figures with the vessel’s declared figures and if a discrepancy is noted, re-gauge the ship’s tanks.
Conduct a full initial gauging of all the barge tanks and record the actual initial quantity of bunker fuel on the barge.
Ensure that the sampling equipment is set up properly to draw the bunker drip samples from the manifold during the bunkering.
Check that standard safety procedures for bunker transfer are complied with.
Monitor the ship’s bunker tanks regularly during the bunkering for any signs of abnormal bunkers or entrapped air, etc.
Conduct a thorough final gauging of all barge tanks and record the actual quantity of bunker fuel remaining on the barge.
Conduct a thorough final gauging of all the vessel’s tanks and record the actual quantity of bunkers onboard after completion of bunkering.
Establish the Barge delivered quantity and the vessel received quantity.
Seal and label the bunker samples.
