SILWA provides professional, expeditious, and accredited loss-control and maritime logistics services for beneficial owners, disponent owners, charterers, oil and gas operators, and insurance underwriters across West African ports and offshore terminals.
We provide 10 core specialized maritime and cargo services:
• Pre-Charter Vessel Inspection & Certification
• Surveying, Inspection and Superintendence Services (Draft surveys, bunker ROB/BOD surveys, on-hire/off-hire condition surveys)
• Inventory Management and Sales Monitoring at depots and tank farms

In the West African maritime corridor, poorly-maintained or malfunctioning vessels contribute to over 50% of losses in cargo, berth space, and vessel turnaround time (leading to costly demurrage). Our pre-charter inspections verify hull condition, cargo tank readiness, pumping machinery, and safety systems before charter agreements are executed, protecting charterers and owners from severe financial exposures.
Liquid petroleum or chemical cargoes that fail initial laboratory tests, or those specifically formulated to meet unique client or market criteria, can be precision-blended to acceptable commercial specifications under SILWA superintendence. Additionally, we certify Ship-to-Ship (STS) transfer equipment—including pneumatic rubber fenders, oil transfer hoses, manifold adapters, and emergency pumps—to ensure safe offshore STS lightering operations.
