White Paper Summary
Marine insurance at Berkshire Hathaway Specialty Insurance has evolved far beyond its traditional maritime-focused origins, with only a small part of the company’s marine portfolio actually involving vessels on water, while the remainder encompasses diverse modern risks from data centers supporting artificial intelligence to construction equipment and supply chain coverage. This transformation reflects broader industry shifts as marine insurers adapt to contemporary business needs while maintaining the collaborative expertise that has historically defined the sector.
The term “marine insurance” has become something of a misnomer in today’s market. “When I say marine, everyone thinks about ships, yet our marine portfolio at BHSI is only about 5% on water,” explains Ben Wyatt, Head of Marine, U.S. at BHSI. “The portfolio is comprised of inland marine risks, domestic transportation and warehousing through the cargo stock throughput product.”
This evolution encompasses contractors’ equipment, including everything from warehouse forklifts to construction cranes and port equipment. Oil and gas equipment falls within this category, as does much of the emerging data center work. The marine team also handles smaller builders’ risks, highlighting how construction projects now fall under marine insurance coverage.
“We also have an excellent team that specializes in more complex, larger builders’ risk projects, and we remain very collaborative with them, sharing knowledge, expertise and experience,” he said.
Stock throughput products offer comprehensive transit and storage coverage—essentially cradle-to-grave protection for goods and inventory throughout the supply chain. Despite the product’s value, Wyatt notes that “we’re still having conversations educating established large companies about the benefits of the stock throughput coverage, whether they have a risk manager or not.”
