Find answers to common questions about GOTEC's draft survey equipment, AI algorithms, ballast measurement, container weighing, and smart customs solutions. If you don't see your question here, please contact us.
A draft survey is a method to determine the weight of cargo loaded or discharged from a vessel by measuring the vessel's draft (how deep it sits in the water) before and after loading. It is critical for commercial settlement, customs declaration, and trade compliance. GOTEC's AI-powered approach replaces risky manual boat-based observation with machine vision and semantic segmentation, achieving millimeter-level accuracy. Explore our draft survey equipment to see how we reduce traditional 2-4 hour surveys to under 30 minutes.
GOTEC combines HD cameras with computer vision algorithms. Our semantic segmentation neural networks separate waterline and scale digits, then compute accurate draft values using wave-resistant curve fitting and perspective tilt correction. The system outputs traceable digital records suitable for settlement and regulatory review. Learn more about our visual AI algorithms that power millimeter-level maritime measurement.

GOTEC (Shandong) Equipment Technology Co., Ltd. is headquartered at No. 68 Changsha Road, Shibei District, Qingdao, China. We serve ports, customs authorities, inspection agencies, and cargo owners globally, with deployed solutions across multiple major Chinese ports and growing international presence.
GOTEC's portable ballast water level meter achieves ±5mm precision sensing. It uses high-sensitivity sensor streams combined with rule models to validate touch-water and touch-bottom states, producing reliable tank-level results with one-click operation and automatic data storage for 10,000+ local records. Browse our full range of port measurement instruments, including draft observation and ballast measurement devices.
Yes. GOTEC designs its platform for integration. Our cloud connectivity, API access (available on PRO and Enterprise plans), and support for standard data formats allow integration with weighbridge systems, customs data platforms, and port management software. Contact our team to discuss your specific integration requirements.
Timelines vary by scope. Pilot projects with a single product line typically deploy in 2-4 weeks. Full-scale deployments covering multiple terminals or integrated draft survey + container weighing solutions typically take 2-4 months, including on-site installation, integration, and operator training.
GOTEC employs end-to-end encryption for data transmission, role-based access controls, and full audit trail capabilities. Our Enterprise plan includes SLA-backed security reviews and audit support. All measurement data is traceable from capture to sign-off, supporting regulatory compliance requirements for customs and trade.
GOTEC provides comprehensive support: on-site installation and commissioning, operator training for field teams, technical documentation and integration guides, email and phone support, and optional named technical account management for Enterprise customers. We work alongside operations teams to ensure digital tools deliver real efficiency.
