2 2 JOHN GJERE ROCHURE 2016 JOHN GJERE guarding your values when safety counts! t the end of the day nothing is more important than the health and lives of the people working on board. ccidents sometimes happens and at sea help can be far away. In those situations, the HIE valve has one job: To guard the ship from taking in water, thus stabilizing the situation until the crew and finally the ship, can be brought safely ashore. John Gjerde is located on the west coast of Norway, in the middle of a big innovating maritime cluster - close to ship owners, designers, seafarers, and machinists. With 45 years of experience in the market of air-vent-check valves. We have developed our new optimized G-valve range, named HIE. We have focused on the critical safety aspects with these valves and developed the most reliable and optimized valve in the market That s why you should choose the G-valve HIE!

3 JOHN GJERE ROCHURE THE HIE-FMILY - the new generation G-valves What if the ship is listing heavily, with valves in the water zone or even under water, and the valves fail? For instance, by the float being stuck, damaged or simply gone. The valves will take in water! In the worst case scenario, the pumps could be out of order, either due to electrical failure or black-out, or the machinist having evacuated. This situation will rapidly become very serious for the ship. Which is why the valve s reliability is of the highest importance for safety at sea! What if the valve is slightly too narrow or too tight for the air-flow stream? Suction blocking will occur. With a blocked valve, suction forces will create tension in the tank - which may cause a breakdown in the tank s bulkhead structure. The opposite may also occur: High pressure-drop due to overfilling will force the tank to break down outwardly. Ensuring correct sizing could prevent tank breakdown! Our values and mission: John Gjerde believe in continuous innovation to improve the safety of the crew, their vessels and the environment. We have solid in-house competence using our own test facilities for studying the safety aspects of ships.

4 4 JOHN GJERE ROCHURE 2016 THE VNTGES of the HIE-valves 1. The guiding pin*, which ensures perfect performance even under tilted conditions 2. The unique disc-float shaped for optimal airflow with integrated lip seal gaskets a. Provides protection against damage from overfilling b. Provides efficient noise suppression c. Prevents leakage in dipping situations. This disc and pin concept protects the closing mechanism, and makes the HIE-valve the most reliable in the market. 3. The Hide valve is also small, no wider than the flange 4. The flow area inside is bigger than required by the regulations. This decreases the risk of suction blocking and structural breakdown 5. The flame screen is of robust construction and is re-enforced to prevent breakdown due to water overfill, or debris in the water. The screen is large, which minimizes pressure drop 6. The shield protects the closing mechanism from airborne pollutants such as dirt and spray painting 7. The heating (winterization) solution (option) a. Ensures working guarding function in icing conditions down to -50 degrees Celsius b. Is simple and robust for reliable operation c. ll valves are pre-prepared for heating as a standard for easy winterization at a later time d. Self-regulating heating system to provide ample heating and still minimize the total power consumption by 80% compared to conventional solutions e. Low power consumption reduce installation cost and generator size f. TEX approved g. IECEx approved 8. Corrosion resistant aluminium, to prevent corrosion by sea water. lso delivered in steel, or other materials 9. Fulfils the mportant requirements in P3.2.5, P3.2.3 and P pproved by all major classification societies: Options Flame-/ug-/Rat- sceen Heating /Winterization With mud chamber.

27 JOHN GJERE ROCHURE WTER TRP liquid water trap The John Gjerde water trap has been designed to prevent water loss from the stability tanks, preventing any decrease in the stability of the ship. In severe weather conditions, which will cause a lot of rolling and pitching of the ship and thus a high level of filling for the stability tanks, the John Gjerde water trap will prevent the accidental discharge of water through the air pipe heads. John Gjerde water trap is placed underneath the (John Gjerde) air pipe heads. This construction can also be used for ballast water tanks or tanks where similar situations could occur. nother positive side effect is that when the John Gjerde water trap is combined with our ERO and HIE air pipe head (with the patented HIE technology), extremely high inlet air speeds can be faced and so called suction blocking, e.g. vacuuming of the float, will no longer occur.
