What Sea Partners does

Sea Partners is a privately held maritime consultancy headquartered in Valparaíso, Chile, providing ship owners and maritime industry stakeholders with professional consultancy, project management, and supervision services for new building and conversion projects worldwide. Its core offerings are organized around five engineering-led service lines — Evaluation & Contracting (shipyard selection and contract negotiation, with particular depth in Far Eastern yards in South Korea, Japan, and China), Plan Approval (regulatory compliance review and anticipation of upcoming rules), Equipment evaluation and manufacturer negotiation, Vessels Survey (pre-purchase and pre-charter condition surveys across chemical tankers, product tankers, bulk carriers, container vessels, and sailing vessels), and Ultrasonic Thickness Measurement delivered by ISO 9712–certified inspectors deployable worldwide in ports, shipyards, or at sea. The firm also runs a Retrofit Projects practice tied to new regulatory cycles and a Broker Division that includes a Marine Technology Broker (R+D+I and technology transfer support for research centers and technology companies) and a Live Fishing Vessels Broker serving the Chilean salmon industry.

The company is built around six named partners who are naval architects, merchant marine engineers, and project managers drawn from the Chilean Navy, Humboldt Shipmanagement, Ultranav Group, Asenav, Detroit Shipyards, and supervision roles at major Korean shipyards (DSME, STX, Samsung). This talent base — rather than proprietary software — is the core delivery mechanism. Sea Partners is a sales-led, professional services firm with custom quote-based pricing per engagement, direct-to-shipowner distribution, and a website that functions as its primary marketing surface. There is no software product, API, or mobile application; services are delivered by deploying people to shipyards and vessels globally. The firm is not publicly listed, has no disclosed institutional funding or parent company, and operates as a founder/partner-owned boutique with an estimated 9 employees.

Broad incumbents

• DNV: DNV's Maritime advisory division provides ship classification, newbuilding supervision, plan approval and survey services, directly overlapping Sea Partners' core offering but with substantially larger global resources and bundled class-society authority.
• Lloyd's Register: Global classification society with an advisory arm providing plan approval, newbuilding supervision, UTM surveys and retrofit consulting across all major vessel types; competes with Sea Partners on technical supervision but as part of a much broader classification and digital portfolio.
• Bureau Veritas Marine & Offshore: Bureau Veritas offers classification plus marine consultancy, including newbuilding supervision, plan approval and condition surveys; overlaps with Sea Partners across the full newbuilding-services stack but at significantly greater scale.
• Inchcape Shipping Services: Inchcape provides a global portfolio of maritime services including surveys, vessel agency and port-call support, overlapping with Sea Partners' survey and supervision offering but as a much larger diversified maritime services business.
• American Bureau of Shipping (ABS): ABS delivers classification, plan review and newbuilding survey services to shipowners and shipyards globally, competing with Sea Partners on technical supervision and regulatory advisory for major newbuild and conversion projects.
• Clarkson Research (Clarksons): Clarksons is the world's largest shipbroker with a research and advisory arm serving shipowners on newbuildings, sale & purchase and chartering decisions — comparable to Sea Partners' Evaluation & Contracting and Vessel Survey services, but at much greater scale.
• RINA Services: RINA provides classification, technical advisory and supervisory services for shipowners and yards, including plan approval and shipyard supervision — a broad incumbent peer of Sea Partners with deeper class-society backing.

Direct peers

• BMT Group: BMT is a UK-headquartered maritime engineering consultancy providing naval architecture, ship design, owner's engineering and surveying services to shipowners and operators worldwide — the closest direct comparable to Sea Partners' shipbuilding supervision and project management offering.
• Marcon International: Marcon is a US-based ship sales, yacht brokerage and consulting firm offering vessel surveys and newbuilding advisory to owners and operators — a closely comparable boutique maritime services firm competing with Sea Partners in the vessel-survey and brokerage space.

Emerging players

• Maritime-Insight: Maritime-Insight is an emerging independent maritime advisory and vessel-survey practice that overlaps with Sea Partners' brokerage, pre-purchase surveys and newbuilding advisory offerings — a smaller, niche competitor in the boutique end of the market.
