Research Vessels (R/V's) and Cruises of the IMS - METU

IMS - METU Research Vessels (R/V's)

Institute owns three research vessels: the 433 gross tons R/V Bilim-2, which is used for ocean research including fisheries, and two smaller vessels of 16m length: the Lamas-1 and the Erdemli for daily trips in near shore regions.

As a contribution to the history of the institute, an initiative has been started to rescue, organize and publish information about the cruises.

Finding complete 30 years old files (and sometimes even not so old ones) was not easy and not always possible, because some of them are missing.

Contribution of any readers to complete these data are welcome.

Detailed info about IMS METU cruises you can get at the Cruises Web Page of Activities section

R/V Bilim-2 (Bilim before 2006)

The Institute of Marine Sciences' main research vessel Bilim was designed as an oceanographic vessel and was launched in 1983. Steel hull, Length: 40.36 m, Beam: 9.47 m, Tonnage: 433 gross, 190 net tons, Draft: 3.80m, Speed: 11.5 knots max, 9.5 knots cruising, 1.0 knot min, Range: 6500 miles, Propulsion: MWM diesel, 820 HP, variable-pitch propeller, Schafran bridge control unit, fuel capacity 120 m3. A Global Positioning System (GPS) is used for navigation. The vessel also has conventional radar with 60 miles range. The ship has central partial air conditioning and central heating. 

The R/V Bilim-2 (Bilim before 2006) has quarters for a crew of 12, and can support a scientific party of 14 for a period of about 45 days at sea.

Physical and chemical data on board of the Bilim are obtained utilizing a Sea-Bird Model 9 CTD profiling system together with a General Oceanics rosette sampler having 12 bottles of 5 liter volume. The CTD and the rosette are operated using a Lebus hydrographic winch with a 2000m cable. For on-board analyses an automatic Winkler titration system, an auto-analyzer, an in-situ spectrofluorometer, an irradiance meter as well as other instruments are available.

The vessel is fully equipped for fisheries and marine biological studies. Some of the major equipments for these investigations are a Norlau hydraulic trawl winch of 7.5 tons and 2 X 1500m wire capacity, a hydraulic net winch of 6 ton capacity.

Marine geological investigations are carried out using an EG&G Uniboom shallow seismic system, side-scan sonars, and various corers. An underwater remotely operated camera (Mini Rover Benthos MK II) is also utilized in sea floor surveys.

Electrical Power Supply

380v-220v AC power is supplied by two 175 HP (each) MWM diesel generators which can be connected in parallel if needed. 220v AC is supplied to the laboratories through a 10kVA isolation transformer, and also by a 3kVA continuous power supply unit. One 12 Kw MWM diesel generator for emergency power supply is also available.


9x8 m2 lab space is available on the main deck for analytical and wet labs, where chemical, and nutrient analyses are carried out. A data-collection and processing room, equipped with computers, IEEE-488 interface, A/D converters, parallel/serial interfaces, accommodating deck units of various instruments, is located adjacent to the labs. Biology, and optical labs, and small machine-shop are located below the deck.
