Teavitame TrAmi, et plaanime teostada ajavahemikul 14.04. – 31.07.25 Saare-Liivi meretuulepargi (SLOWP) merealal Liivi lahes geotehnilisi uuringuid. Uuringuid teostatakse jack-up pargaselt JAKUP. Läheduses viibi Alfons Hakans puksiir, mis jack-up pargast opereerib. Pargase ja Kihnu sadama vahel hakkab sõitma CTV, mis vahetab 12h tagant tehnikumeeskondi. Tööd toimuvad ilmastikust lähtuvalt 24/7. Teiseks palume väljastada poiluba. Plaanime veesata merealal lainepoi. Lainepoi on kollane ning varustatud märgutulega. AIS puudub. Lisasin kirjale tootelehe. Poi luba palun väljastada aasta lõpuni. Lainepoi asukoht: Lat: 58° 04' 56.8712" N Lon: 023° 37' 45.1555" E Vastan võimalikele küsimustele.
