SHIP SOUNDING SURVEY IN SAUDI ARABIA

EIWAA Marine Survey services offers Ullage Survey, 3D Laser Calibration Services and Ship Sounding Survey Services in Saudi Arabia Ports and offshore.The process of precisely calculating the cargo tank volume to ascertain the precise cargo or products, whether in liquid or solid form, is known as ship cargo calibration. The act of gathering data for a cargo tank and using those measurements to calculate an accurate tank capacity is known as ship tank calibration. The liquid depth in a tank is called “sounding,” and it is determined by measuring the liquid’s surface to a point at the bottom of the tank;commonly known as Ship Sounding Survey. Ships may need sounding table or ullage survey reports in order to load or discharge items as part of cargo tank calibrations. Our skilled naval architects and marine engineers can use EIWAA’s sophisticated tank gauging system software to calculate the sounding table or trip capacity table for cargo ships.

Internal Electro-Optical Distance Ranging Method (EODM) by 3D laser scanning supported by our advanced software is required where  Cargo tanks undergo major repair/alterations. Supply of Dipstick or ullage bar are engraved with large legible markings used for dip measurements. After Barge/Vessel tank calibrations, our deliverables are ullage tables and sounding tables with calibration charts

The volume of liquid cargo, such as crude oil, petroleum products, chemicals, and similar products loading  or discharging  on tanker ships, is determined by using ullage survey method. It is, in short, a weight calculation method. Based on measuring the empty space above the cargo in the tanks and performing basic static calculations, this method is used. By using the ullage survey , ship’s cargo weight easily determined by advanced 3D Scanning technology.

The ullage method refers to the measurement of the distance (i.e., the space) between the liquid’s surface and the top of the inner surface of a tank. These ullage tables are produced in relation to a tank’s interior volume as measured from a reference point. Method of Sounding Survey Services is the reverse to the ullage survey services. This approach involves measuring the distance between various reference points at the tank’s bottom and the liquid’s surface to determine the depth of a tank of liquid.

BARGE TANK CALIBRATION

Sounding surveys come in two varieties: automatic and manual. The manual method of barge tank calibration services  involves placing a sounding tape within the sounding pipe and lowering the bob until it reaches the bottom. Marine Services offers onsite calibration services such as ship tank calibration, barge tank calibration, offshore surveying, ship sounding survey, and ullage survey, among other onsite calibration services in Saudi Arabia. According to IMO regulations, ship sounding services must be provided to the every five years to ensure the cargo tanks operate smoothly. 

Deliverables of Barge tank Calibration Services are,

  • Ship Sounding Survey Chart
  • Calibration Table
  • Temperature Correction Chart
  • Sounding chart

The ship’s cargo tanks have been charged to capacity because of modifications or inaccurate calculations. This situation calls for the use of our sophisticated software’s internal Electro-Optical Distance Ranging Method (EODM) via 3D laser scanning. While this approach works well for any ship, it is particularly useful for floating storage vessels, transport barges, chemical tankers, bunker tanks, and other structures where precision is crucial. For ease of reading, large, readable markings are etched on dip sticks and ullage bars. Deliverables are ullage tables, which are used in load calculations to determine whether ships are transporting liquid cargo, following barge/vessel tank calibrations.

ULLAGE SURVEY IN SAUDI ARABIA 

Ship and vessel cargo tank calibration according to sounding/ullage booklet basis for various increment level and trim. The volume correction factor, expansion coefficient, trim correction temperature, and ullage of each cargo tank are all thoroughly analyzed in a cargo tank ullage survey report. By using modern Total Station Survey or laser measurement services for ship or vessel tanks, the Electro optical distance ranging method, also known as EODR, can be evaluated by 3D scanning remote sensing. Utilizing modern remote sensing techniques for 3D imaging and modeling services, safe fill height and tank capacity calculations must be made. Asbuilt drawing preparations and ullage survey services  are created using LiDAR scanning services for cargo tanks for onsite calibration. Tank as-built models are produced by Offshore Services’ 3D Rendering. The volume of liquid cargo, such as crude oil, petroleum products, chemicals, and similar products loading  or discharging  on tanker ships, is determined by using ullage survey method. It is, in short, a weight calculation method. Based on measuring the empty space above the cargo in the tanks and performing basic static calculations, this method is used. By using the ullage survey , ship’s cargo weight easily determined by advanced 3D Scanning technology.

The ullage method refers to the measurement of the distance (i.e., the space) between the liquid’s surface and the top of the inner surface of a tank. Ullage tables are located on the ships. These tables are produced in relation to a tank’s interior volume as measured from a reference point. The sounding method is the opposite of  Ullage method. This approach involves measuring the distance between various reference points at the tank’s bottom and the liquid’s surface to determine the depth of a tank of liquid.
