Vessel and Marine Assurance Services
Ensuring Safe, Compliant, and Efficient Marine Operations
ABL offers a comprehensive range of vessel assurance services designed to verify that marine assets meet the specific requirements of their contracts and operational environments. Our bespoke assurance process evaluates whether a vessel and its equipment are fit for purpose, taking into account the nature of the work, associated risks, and technical specifications.
Each assurance program is tailored to the vessel’s role and operational context, drawing on a wide range of disciplines. These may include assessments of marine systems, dynamic positioning, lifting equipment, and more.
With a team of certified OVID and CMID inspectors, ABL brings deep expertise across offshore renewables, oil & gas, and maritime sectors. Our global experience enables us to deliver detailed, risk-based assessments that support safe and efficient offshore operations.
