Marine Type Approvals
The entire marine temperature sensor program from Kjaerulf Pedersen a/s is type approved by six of the world’s leading classification societies: DNV, Lloyd’s Register, Bureau Veritas, ABS, ClassNK and RINA. These approvals cover your vessels wherever they operate, ensuring global compliance.
Six classification societies behind one program
The marine temperature sensor program holds a type approval from each of the six societies below.
What a marine type approval means
A marine type approval is an official certification from a classification society, confirming that a product type meets the society’s rules for safety, quality and performance in maritime use. For temperature sensors, that means documented performance under the conditions of life at sea: vibration, saltwater, moisture and extreme temperatures.
Each society issues its approval separately, against its own rules. At Kjaerulf Pedersen a/s, the six approvals cover the marine temperature sensor program — from exhaust gas sensors on the main engine to room sensors in the provision cold store.
Why six approvals
Marine operations are global. Fleets are classed by different societies, vessels change owners and routes cross every register — and equipment on board may need to meet the standards of the society that classes the vessel. Six type approvals mean the same marine temperature sensor program can be specified across fleets classed by DNV, Lloyd’s Register, Bureau Veritas, ABS, ClassNK or RINA — on newbuild projects at the yard as well as for a single replacement sensor in service.
Where the approved program works
The approvals follow the sensors into every temperature measurement on board. The applications are described in depth on the Marine industry page:
Engines
Exhaust gas, cooling water, lube oil and bearing temperature on two- and four-stroke engines.
Marine: Engines →Stern tube
Continuous stern tube bearing monitoring — early warning of lubrication failure, misalignment and seal degradation.
Marine: Stern tube →Ballast
Temperature measurement in ballast systems, auxiliary loops and control stations.
Marine: Ballast →Rooms & HVAC onboard
Provision cold stores, freezer compartments, damp rooms and air handling.
Marine: Rooms & HVAC →Frequently asked questions — marine approvals
What is a marine type approval?
A marine type approval is an official certification from a classification society, confirming that a product type meets the society’s rules for safety, quality and performance in maritime use. For temperature sensors, that means documented performance under the conditions of life at sea: vibration, saltwater, moisture and extreme temperatures. Each society — DNV, Lloyd’s Register, Bureau Veritas, ABS, ClassNK and RINA — issues its approval separately.
Which classification societies have type approved Kjaerulf Pedersen a/s marine temperature sensors?
The entire marine temperature sensor program from Kjaerulf Pedersen a/s is type approved by six of the world’s leading classification societies: DNV, Lloyd’s Register (LR), Bureau Veritas (BV), American Bureau of Shipping (ABS), Nippon Kaiji Kyokai (ClassNK) and Registro Italiano Navale (RINA).
Why do marine temperature sensors need approval from more than one classification society?
Because marine operations are global. Vessels are classed by different societies depending on owner, flag and market, and equipment on board may need to meet the standards of the society that classes the vessel. With six type approvals, the same marine temperature sensor program can be specified across fleets classed by any of the six societies — for newbuild projects as well as replacement sensors in service.
Where are marine-approved temperature sensors used on board?
Across the ship’s temperature measurements: exhaust gas, cooling water, lube oil and bearing monitoring on two- and four-stroke engines; stern tube bearing monitoring; ballast systems; and provision cold stores, freezer compartments and HVAC onboard. Each application is described on the Kjaerulf Pedersen a/s Marine industry page.
