BUNKER QUANTITY SURVEY
As bunker fuel is often the largest contributor to the operational costs of a ship, it is critical that the fuel purchaser ensures the correct amount of fuel is received, or has sufficient information to substantiate their claim in the event of any dispute.
As bunkering operations often take place some distance from the fuel purchaser’s office, it is in their interest to engage a surveyor to verify the quantity delivered and oversee fuel sampling for laboratory analysis.
Responding to these concerns, Aegis offers impartial and independent bunker quantity surveys (BQS) through our network of laboratories and offices, covering around 20 ports in over 5 countries. Bunker fuel measurement, sampling and testing are conducted to accepted industry standards and accreditations, including ISO 13739, SS600, TR48, ISO 17020 and ISO 17025. In addition, clients’ own procedures can also be followed when stipulated.
The Aegis surveyor will also oversee and supervise bunker fuel sampling before arranging fuel quality testing at a convenient laboratory.
Reports issued for bunker quantity surveys include:
- A quantity delivered calculation based on density and water testing
- Detailed bunker survey and analytical fuel reports
- Photographs as requested and when permitted
DRAFT SURVEY
Draft surveys are used to determine the weight of bulk cargo such as iron ore, coal, steel scrap, grain and some specific quantities of liquid cargo loaded onto, or discharged from, a vessel.
Draft surveys are convenient and economical means of ascertaining the quantity of cargo loaded or discharged from a ship by reading the vessel’s drafts, measuring the ballast water, fuel and diesel oil and other liquids on board, and calculating the final quantity by using the vessel’s approved deadweight scales and tank tables, etc.
In principle, draft surveys require only a measurement of the water displaced by the vessel before and after the cargo is transferred, along with a measurement of the water’s density. Water displacement is measured through draft marks on the ship and converted to a volume using draft tables. The weight of displaced water is calculated by multiplying its volume (displacement) by its density. The difference between the weights of water displaced before and after the cargo transfer will equal the weight of the cargo within measurement accuracy limits.
BUNKER DETECTIVE SURVEY
221B or bunker detective surveys are carried out by our surveyors on behalf of the charters to find concealed (hidden) bunker fuel onboard.
In order to prevent the loss of bunker fuel, our qualified bunker surveyor's will offer impartial, independent quantity measurement inspection services for marine fuel, providing a detailed bunker survey report highlighting and assuring the not declared fuel on board.
How Bunker Fuel is Concealed?
There are many ways to conceal fuel on a vessel - some of the examples are:
•Hidden compartments
•Use of 'magic pipes'
•Altered sounding pipe lengths
•Non-class approved and / or altered sounding tables
•Sounding tapes not properly calibrated
On/Off Hire Condition Survey
This inspection is conducted to the vessel at the beginning and/or end of the chartering and aims at checking the overall condition of the vessel.
The on/off hire condition survey is an inspection of vessel’s holds, main deck, cargo working areas and external shell plating. It is performed in order to identify any damage present prior to the vessel going on/off hire.
By doing it repetitively for many years, our surveyors became experts in analysing a vessel. The eyes of an experienced professional inspect every bulkhead, ladder, pipe, corrugate, lower and upper hoppers, bilge, tank top plating, manhole, hatch coaming, hatch covers and many other structures.
Aegis Surveys start the attendances of on/off hire condition surveys at berthing time, before the commencement of loading operation, or, at the end of a discharging operation, in order to inspect the holds without cargo inside to be more precise.
Our company details the findings of the inspection in the Survey Report that includes the anomalies found, general particulars of the vessel, relevant documents and a photography list showing the actual condition of the vessel. Aegis works to issue the Survey Report within three days after the completion of inspection.
This survey is compared with the previous condition survey carried out to the vessel, in order to determine if new damage have occurred to the vessel from cargo operations and/or stevedores damage.
