Bay Valves

What Bay Valves does

Bay Valves ApS is a private Danish engineering firm headquartered in Nyborg, Denmark that designs, manufactures, and services high-pressure valves and integrated tank ventilation systems for the maritime and offshore industries. Its portfolio is built around a proprietary magnetic Mini-Slip technology — originally patented in 1972 and combining weight activation with magnetic force — that eliminates valve hammering and minimizes volatile organic compound (VOC) emissions on cargo tanks. Core products include High Velocity Valves (rapid 2-second cycle, certified to IMO MSC/Circ.677 and ISO 15364:2021), the digitally-instrumented SuperSat smart valve system with optional SCADA integration for continuous pressure and VOC monitoring, Pressure-Vacuum Relief Vent (PVRV) valves with ATEX certification for FPSOs, and portable / workshop test equipment meeting ISGOTT and IBC Code requirements.

The company sells primarily through an enterprise field-sales motion: skilled engineers conduct vessel-level assessments, co-develop custom solutions with shipowners, and close projects against long sales cycles. Revenue comes from hardware sales of valves and test equipment, custom engineering services for class-approved upgrades, and recurring service / overhauling work during dry-docking. Distribution is a hybrid of direct offices in Denmark, Romania, Greece, Turkey, China, and Korea, plus a network of regional resellers covering Spain, Italy, the US, Norway, Cyprus, Russia, Singapore, and the UAE.

Bay Valves targets four primary use-cases — FPSO operators, oil and chemical tanker operators, offshore support vessels, and methanol-fueled vessels — with a customer base that includes Shell, COSCO, PDVSA, MISC, Yinson, Sovcomflot, Sinochem, Stena Drilling, and others, spanning 72+ clients across 300+ projects. The firm competes on regulatory compliance depth, customization capability, and emissions-reduction economics (claiming up to 65% VOC loss reduction during FPSO operations), rather than on volume or price.

Products and services

• High Velocity Valves (HI Jet ISO) Advanced safety valves combining magnetic Mini-Slip technology with weight activation for rapid 2-second cycle opening, eliminating valve hammering and preventing flame passage. Certified as flame arresters per IMO MSC/Circ. 677, with close-to-zero VOC loss and high-speed venting for FPSO protection. Compliant with ISO 15364:2021 and ISO 16852:2016.
• SuperSat System Smart VOC emission control system featuring pneumatically operated actuator, 4-20 mA controller, and pressure/flow transmitters. Maintains continuous high-level cargo tank pressure at or above Saturated Vapor Pressure (SVP) to minimize VOC evaporation and cargo boil-off, with optional integrated SCADA software for monitoring, reporting, and verifying emissions.
• Pressure Vacuum (P/V) Valves Pressure-vacuum safety valves for maintaining stable tank pressure during loading, storage, and off-loading operations. Includes PVRV valves (pressure-vacuum relief vent valves) certified for FPSO vessels with ATEX certification, featuring adjustable negative pressure drop and in-situ maintenance capability.
• Test Equipment (Portable Test Kit and Workshop Test Bench) Valve testing equipment comprising a portable test kit for on-site testing of high velocity and PV valves on vessels without EEx-requirement, and a workshop test bench for establishing and adjusting set pressures and establishing leakage rates. Meets or exceeds ISGOTT and IBC Code requirements.
