The changing dynamics of global maritime business create new and emerging risks for all aspects of the sector, from onshore and onboard technology to the drive for new vessel design and cargo throughput systems.

Our dedicated in-house international surveying and investigations team has a proven track record of supporting our major clients on a range of complex projects worldwide.

As coastal states, regulators, and maritime agencies play an ever-greater role in the event of a marine loss; it has created a demand for timely incident response and support.

Our team will provide expert incident response support and resource tracking, cost auditing alongside third-party risk and claims management. As restricting the environmental impact of complex marine losses becomes a priority, our team delivers comprehensive environmental risk management and natural resource damage assessment.

New cargo system technology drives cargo movement across the world, both onboard and onshore, in major ports and terminals. The growing size of vessels and ports creates new aggregation risk levels, exacerbated by the rise in extreme weather events’ frequency and severity.

In turn, we see the growth in significant cargo loss events and the theft and damage to cargos in ever more disparate areas of the world.

Our dedicated teams take the complexity out of your claims and risk management requirements.
