Our team of accredited marine surveyors operates at major ports across all three regions โ from Mumbai, Chennai, and Kandla in India, to Algeciras, Barcelona, and Bilbao in Spain, to Jebel Ali, Fujairah, and Port Rashid in the UAE โ delivering fast attendance and calibrated, precise measurement wherever your vessel calls. We specialize in loss control, ROB/OBQ assessments, bunker quantity surveys, and on-hire/off-hire inspections, combining decades of combined maritime experience with strict MARPOL compliance. Fully independent and trusted by shipping lines, charterers, and fuel suppliers worldwide, we exist to protect our clients' commercial interests through complete transparency, regulatory integrity, and accurate, actionable data โ 24/7, at every port we serve.
Independent, tailored to industry needs โ the same rigorous standard at every port we cover.
Accurate Remaining On Board (ROB) and On Board Quantity (OBQ) assessments are essential for transparent fuel accounting before and after charter periods or major voyages. Our experienced marine surveyors thoroughly sound all bunker tanks, inspect sounding pipes, apply precise trim/list corrections, and rigorously calculate fuel quantities using the latest API/ASTM tables. This leaves no room for ambiguity, ensuring all parties have a reliable baseline for fuel consumption and cost allocation.
Our independent Bunker Quantity Surveys (BQS) provide meticulous measurement and verification of marine fuel quantities during supply operations. Acting as an impartial third party, we protect owners and charterers against short-delivery and "cappuccino" bunkering effects. We gauge tanks on both the receiving vessel and the bunker barge before and after delivery, closely monitoring the transfer process to ensure that the exact quantity stated on the Bunker Delivery Note (BDN) is physically received and properly accounted for.
Comprehensive on-hire and off-hire bunker surveys are critical for preventing disputes when a vessel enters or completes a charter agreement. Our surveyors conduct meticulous inspections of all fuel oil and diesel oil tanks to certify the exact quantities on board at the specific time of delivery or redelivery. By providing detailed, independent survey reports accompanied by photographic evidence and signed certificates, we deliver the indisputable documentation needed for seamless commercial handovers.
Professional bunker sampling is the first line of defense in ensuring marine fuel quality compliance and preventing costly engine damage or MARPOL disputes. We strictly adhere to MARPOL Annex VI regulations and continuous drip sampling methods at the ship's manifold. Our surveyors securely seal, label, and document each representative sample, ensuring a verifiable chain of custody that holds up under scrutiny during any potential commercial or regulatory claims.
Accurate measurement and documentation of sludge and slop quantities are vital for environmentally compliant disposal operations. We conduct detailed sludge disposal surveys to verify the volumes of waste oil offloaded from the vessel to reception facilities or barges. Our independent reports help ship operators maintain accurate Oil Record Books (ORB), ensure strict compliance with international environmental regulations, and avoid penalties associated with improper waste tracking.
To guarantee the structural integrity of your engine and compliance with global sulfur caps, we offer comprehensive fuel analysis through external ISO-accredited testing laboratories. We manage the fast-tracked dispatch of bunker samples and provide detailed analytical reporting on critical parameters including viscosity, density, sulfur content, cat fines, and water content. Our swift turnaround times ensure that you have actionable quality data before the fuel is consumed.
