Mjellem & Karlsen Of Norway To Build Two Oceanographic Vessels

Two oceanographic research vessels, one for the University of Mexico, the other for the University of Bergen, Norway, will be built by the Norwegian firm A / S Mjellem & Karlsen, specialists in the design and construction of such vessels. Both universities will be carrying out similar investigations covering a wide range of activities in physical and chemical oceanography, geology, geophysics and biology.

The ships are based on the yards Nansenclass research vessels, of which four have been built so far. These flexible vessels have a very low hydroacoustic noise level, enabling the use of hydroacoustic instruments at near full speed. Various stern trawls are employed for launching, towing, and retrieving oceanographic sampling equipment. Several cranes and winches, arranged for maximum flexibility, are mounted around the spacious aft deck so as not to obstruct it.

The laboratories and instrumentation are designed for adaptability and easy expansion if the need arises.

The Norwegian vessel will have built-in seismic capability, while the Mexican vessel will use skid-mounted equipment when necessary.

Main particulars for the Mexican vessel are as follows: length overall, 50.25 meters (165 feet) ; breadth, 10.30 meters (34 feet) ; depth to shelter-deck, 6.50 meters (21 feet) ; draft, 4.30 meters (14 feet) ; speed, a p p r o x i m a t e l y 13 knots, and duration of cruises, one month.

The A / S Mjellem & Karlsen yard, which employs approximately 500 people, was established in 1891, and is situated near the center of Bergen.
