TNorth Atlantic fisherypro tection and inspection serviceof the Royal Danish Navy wasestablished in 1587 by a RoyalDecree and carried ou t by frigatesand other men-of-war. With onlyminor interruptions, the serv icehas operated ever since. AfterWorld War I, specially designedinspec tion ships were introdu ced ,and from 1932 sea-planes basedon the ships were used to extendthe range of inspection . Helicop­ters repla ced the sea-planes in1962. Thus the design and con­struction of the new »Thctis­class patrol frigates rest on morethan 400 years of expe rience inFaroe and Greenland waters,com bined with 30 years of ex­perience in the operation of ship­based helicopters in some of theroughest waters in the world.

In 1977. the Danish economiczone was expanded to 2(x) nauti­cal miles from the coast of Green­land and the Faroe Island s. It be­came clear that the next gener­ation of vesse ls for service inthese waters had to be faster. morelong-legged and better equippedthan the ships in service at that time.

Th e design of the »Th eti se classpatrol frigate is based on stand­ardization with existing Danishnaval eq uipment and softw are.Th e technological standardsachieved ensure reliable. safe andeconomic operations. It has beenpossible to construct the vessels

of this class at a very low price.Operating costs have also beenmarkedly reduced . due to thestandardization achieved and thehigh degree of onboard autom a­tion.

The Danish Naval Materiel Com ­mand is proud to present the pa­trol frigates of the »Thetis« classand its contractors.

In cruise liners, passenger shipsand yachts, the air conditioningsystem has a high priority. Gener­ally, the requirement s for interiorconditions are grea ter than thosefor cargo vess els.

The TWI N-PIP E system is thesolution for cabin areas . For pub ­lic compartments, the low-pres­sure VAV system (Variable AirVolume) comprises VAV airhand ling unit s, and a zone­divided low-pressure rectan gularduct system with grilles and dif­fusers integrated in the ce ilings.Thi s system is perfect for large

. Th e TWIN-PIPE system meet­ing more sophisticated requir e­ments , is mo stly used aboardpassenger ships and yach tsoften with fully automatic, indi­vidua l control in the cabins.

NOVENCO HI-PRES is the solu­tion when small duct dim ensionsare required , and individual con­trol in each cabin is required. Thelow sound level of the HI-PRESsystems, together with the con ­tinuous development of sound re­ducing measures, will also fulfilthe requ irements of tom orro w.
