BJORK LEGAL Advokaadibüroo Riigihangete vaidlustuskomisjonile 12. jaanuar 2026.a. e-post: [email protected] Vaidlustaja: Osaühing Easy Agency Registrikood 12203033 esindaja: vandeadvokaat Kaimo Räppo e-post: [email protected] Hankija: Riigi Kaitseinvesteeringute Keskus Kolmas isik: BMG Energy OÜ Registrikood 16388644 Riigihange nr 303681 „Diiselmootori ostmine koos transpordi ja paigaldamisega Ämarisse“ VAIDLUSTUS Hankija Riigi Kaitseinvesteeringute Keskuse 9.1.2026. a otsusele riigihankes nr 303681, millega Easy Agency pakkumus lükati tagasi RHS § 114 lg 2 alusel ja tunnistati edukaks BMG Energy OÜ pakkumine TAOTLUSED: 1. Tunnistada kehtetuks Hankija Riigi Kaitseinvesteeringute Keskuse 9.1.2026. a otsus riigihankes nr 303681, millega Easy Agency pakkumus lükati tagasi RHS § 114 lg 2 alusel ja tunnistati edukaks BMG Energy OÜ pakkumine ning otsustati asuda ostutellimust ette valmistama BMG Energy OÜ-ga. 2. Mõista välja vaide esitaja kulud riigilõivuna 640 eurot ja õigusabikuluna 540 eurot (3 h õigusabi hinnaga 180 eurot tund). 3. Vaidlustuse eesmärk 4. Vaidlustaja palub tunnistada kehtetuks Riigi Kaitseinvesteeringute Keskuse 9.1.2026. a otsuse. BJORK LEGAL Advokaadibüroo Tatari 16-4 Tallinn | +372 51 35 215| [email protected] 5. Selle otsusega lükati riigihankes nr 303681 tagasi Easy Agency pakkumus RHS § 114 lg 2 alusel ja tunnistati edukaks BMG Energy OÜ pakkumine ning otsustati asuda ostutellimust ette valmistama BMG Energy OÜ-ga. 6. Asjaolud ja menetluse käik 7. Juunis 2025 sai Ämari Lennubaasi tuletõrjesüsteemi diiselmootor testimise käigus ulatuslikult kahjustada. 8. Augustis 2025 teostas vaide esitaja kahjustatud mootori tehnilise ülevaatuse ning järeldas, et olemasoleva mootori remont ei ole tehniliselt ega majanduslikult otstarbekas. 9. Septembris 2025 osales vaide esitaja hankija tehnilise osakonna palvel asenduslahenduse väljatöötamises ning 27.09.2025 soovitas radiaatoriga diiselmootorit koos jahutusvee temperatuurianduriga. 10. Sama kuupäevaga esitati hinnapakkumus summas 20 020 eurot + km, mis sisaldas ka paigaldust. 11. Mitu kuud hiljem ehk detsembris 2025 kuulutati välja siinne riigihange nr 303681. 12. Vaide esitaja ehk hankijaga varasemalt suheldu OÜ Easy Agency esitas riigihankele pakkumuse koos tehnilise spetsifikatsiooni ja tootja manuaaliga. 13. 15.12.2025 küsis hankija täiendavalt mootori tehnilist dokumentatsiooni, mis edastati 17.12.2025. 14. 09.01.2026 lükkas hankija OÜ Easy Agency pakkumuse tagasi RHS § 114 lg 1 ja 2 alusel ning tunnistas edukaks BMG Energy OÜ pakkumuse. 15. Vaide põhjendused 16. Tagasilükkamise põhjendus on, et pakutud mootoril pudus jahutusseade. Selline põhjendus on vale, sest jahutusseaduse on pakutud mootoril olemas. Jahutusseadme täpsemat spetsiifikat, mis nähtub enne hanke korraldamist poolte kirjavahetusest, hanke käigus ei küsitud. 17. Seega, pakutud mootoril oli jahutusseade – alus pakkumuse tagasilükkamiseks puudus. 18. Hankija lükkas vaide esitaja pakkumuse tagasi põhjendusel, et tehnilise kirjelduse punkti 3 nõue (jahutusseadme olemasolu) ei olnud täidetud. 19. See järeldus on faktiliselt vale ja dokumentaalselt ümber lükatud. 20. Vaide esitaja esitas hankijale tootja tehnilise dokumentatsiooni (lisa 4), millest nähtub, et pakutav mootor on jahutussüsteemiga mootor. Tegemist on tootja poolt määratletud mootorikomplektiga ENGINE COMPLETE – COOLING, osa nr 504190611, mis oma olemuselt ja tootja klassifikatsiooni järgi sisaldab jahutusseadet ning on ette nähtud töötamiseks koos vedelikjahutussüsteemiga. Viidatust nähtub, et „Kui jahutusvedeliku temperatuur ületab etteantud väärtused, sulgeb termostaatklapp osaliselt või täielikult tagasiringluse pumba suunas ning avab tee jahutusvedeliku / merevee soojusvaheti suunas. 21. Seega - jahutusseade oli olemas, tehnilise kirjelduse punkt 3 oli täidetud ja hankijal puudus faktiline ja õiguslik alus lugeda pakkumus mittevastavaks. Kõnekas on ka hankija varasem suhtlus vaidlustajaga ja siis ootamatu seisukoht, et vaidlustaja septembrikuine pakutud lahendus ei sobi (ei soovita vaidlustajaga jätkata). Selle asemel korraldati hoopis siinne hange. 22. RHS § 114 lg 1 ja 2 õigusvastane kohaldamine. RHS § 114 lg 1 kohaselt tuleb pakkumus tagasi lükata vaid juhul, kui see ei vasta hankedokumentides esitatud tingimustele. RHS § 114 lg 2 kohaselt on tagasilükkamine põhjendatud üksnes juhul, kui mittevastavus on sisuline ja kõrvaldamatu. 23. RHS § 46 rikkumine – selgituste küsimata jätmine. RHS § 46 lg 1 kohaselt on hankijal õigus ja vajaduse korral kohustus küsida pakkujalt selgitusi, kui see on vajalik pakkumuse sisu mõistmiseks. Kui hankijal tekkis kahtlus jahutusseadme olemasolu osas, tulnuks tal küsida selgitusi, mitte lugeda pakkumus automaatselt mittevastavaks. Selgituste küsimata jätmine ja kohene kõrvaldamine on ebaproportsionaalne. 24. RHS § 3 rikkumine – üldpõhimõtted. RHS § 3 sätestab riigihanke üldpõhimõtted, sh a) proportsionaalsuse, b) võrdse kohtlemise, c) läbipaistvuse ja d) säästliku ja otstarbeka rahakasutuse. 25. Vaide esitaja tehniliselt vastav pakkumus hinnaga 19 990 eurot + km lükati tagasi, samas kui edukaks tunnistati ligikaudu 60% kallim pakkumus hinnaga 32 760 eurot + km, ilma sisulise tehnilise põhjenduseta. 26. Hange puudutab Ämari Lennubaasi tuletõrjesüsteemi, mis on strateegilise tähtsusega objekt. Vaide esitaja pakkumuse põhjendamatu kõrvaldamine on viinud olukorrani, kus süsteemi taastamine on viibinud ning avalikke vahendeid kasutatakse põhjendamatult suuremas mahus. 27. Taotlused 1) Tunnistada kehtetuks Hankija Riigi Kaitseinvesteeringute Keskuse 9.1.2026. a otsus riigihankes nr 303681, millega Easy Agency pakkumus lükati tagasi RHS § 114 lg 2 alusel ja tunnistati edukaks BMG Energy OÜ pakkumine ning otsustati asuda ostutellimust ette valmistama BMG Energy OÜ-ga. 2) Mõista välja vaide esitaja kulud riigilõivuna 640 eurot ja õigusabikuluna 540 eurot (3 h õigusabi hinnaga 180 eurot tund).

The crankshaft is made in steel hardened by induction and Connecting Rods rests on seven mountings; inside the hollow shaft are the ducts for the lubrication oil circulation. Figure 7 On the front tang, the oil pump driving gear, the phonic wheel, the flywheel connecting hub and the driving pulley of the ancillary components are keyed on. On the rear tang the camshaft driving gear and the coupling flange to the engine flywheel are keyed on. The bench half bearings are in cast babbitt lining steel and the 6th is fitted with a shoulder ring to contain the end play of the driving shaft. Details 1 and 2 in the figure, assembled by negative allow- ance on the rear tang, are not replaceable. The front and rear retaining rings are of the slide type with radial seal and require special fixtures to be assembled and disas- sembled. 04_013_N They are made in steel, manufactured by pressing, with small end oblique edged and cap separation obtained by fracture splitting technique. The connecting rod half bearings are cast babbitt lining steel. Every connecting rod is marked on the body and on the cap by a number that identifies their coupling and the cyl- inder into which it is to be assembled; moreover, a letter is impressed on the body stating its weight class. In case a replacement were necessary, only one type of connecting rod is available as spare part of an intermediate class weight that can be used to replace any other. Therefore, connecting rods that are still efficient, do not need to be replaced even if they are of a different class weight. N67 MNS M22 1.16 N67 MNT M28 OVERVIEW JUNE 2007 Pistons Timing system driving gear Figure 8 Figure 9 1 04_015_N The timing system driving gear machine is a push rods and rockers type, with a camshaft (1) that is located in the crank- 04_014_N case and set into rotation directly by the crankshaft. The pistons integrate the high swirl combustion chamber; Figure 10 the annular chambers inside the junk ring enable an effective heat elimination obtained by circulating the lubrication oil delivered by the spray nozzles mounted on the crankcase. On the piston skirt the are three seats for the retaining rings; the first one of these is obtained by a special trapezoidal sec- tion cast iron insert. The piston rings have different functions and different geom- etry. 1 - The 1st piston ring has a trapezoidal section and ceramic chrome plating; 3 - The 2nd piston ring has a a torsional conical rectangular seal; - The 3rd piston ring has a double oil scraper with internal spring. 04_317_N 2 1.

The connection of the +B terminal of the alternator to the positive +30 terminal of the electric starter motor must be achieved with a conductor having a cross section of at least 20 mm2. On the engine wiring there is a 6 mm2 section conductor: a 16 mm2 section or – or higher – conductor must be connected to it. The connection of the positive +30 terminal of the electric starter motor to the positive pole of the battery, achieved with a conductor having a cross section of at least 70 mm2, allows to obtain, as shown in the figure, the simultaneous connection of the alternator to the battery. On the same +30 terminal of the start-up electric engine it is necessary to connect the eye battery lead connection marked with “+ BAT (MM)”. The connection between the engine ground and the negative pole of the battery must be achieved according to the guidelines provided in the Engine electrical ground paragraph. CAUTION Do not use any magneto-thermal activation protection items to stop engine. Using off-the-shelf equipment, you stop the engine energizing the proper solenoid valve. In lack of power supply you could not stop the engine.

When the user complains of poor performance or operat- ing anomalies, due consideration must be given to his/her indications, in order to derive useful information that will orient our actions. After ascertaining the existence of the anomaly, we recom- mend starting troubleshooting operations with tests and measurements, to obtain a picture of the overall operating conditions and identify the real fault causes. If adopted diagnostic modes provide no indications, proceed to check ratings and technical data provided in the “N67 MNS M22 Installation Directive” or “N67 MNT M28 Installa- tion Directive” document. We have provided, in the following pages, a TROUBLE- SHOOTING GUIDE organized by symptoms, describing the possible anomalies not recognized by the electronic unit, frequently mechanical or hydraulic in nature. For operation and maintenance instructions, see the indica- tions provided in Section 5. N67 MNS M22 4.90 N67 MNT M28 DIAGNOSTICS JUNE 2007 MAJOR DIAGNOSTIC ACTIONS Checking pressure in fuel supply line Checking component resistance value Figure 1 Figure 2 A 04_086_N Ensure that the system is not powered. The measurement must be taken on each individual compo- nent, isolated from its wiring or connected only to the instru- ment, set as ohmmeter on the appropriate end of scale value (see REFERENCE VALUE table in the pages that follow). At the end, restore the correct connection. B Checking line insulation Figure 3 04_307_N Gauges will be interposed in A and B by “T” unions. Measure- ments have to be carried out at various engine speeds from minimum to maximum at intervals of 200 RPM. 04_087_N Acceptable limit ratings Point Minimum Maximum Figure 4 A - 15 kPa 0 kPa B 0 kPa 30 kPa 04_088_N Ensure that the system is not powered. The measurement must be taken on each individual conductor, isolated from all the components to which it is normally connected.The measurement must be taken with the instrument set as ohm- meter on end of scale value ≥ 200 KΩ, and it must be taken both towards the positive potential and the negative battery potential. At the end, restore the correct connection.
