API Marine has signed a contract with Arctech Helsinki Shipyard for delivery of Tank level Remote Sounding System TSS/BMS4 for icebreaking platform supply vessel (NB 511) and icebreaking stand-by vessels (NB 512-514).

TSS/BMS4 is the next generation of electro-pneumatic systems for level and draught measurement, developed by API Marine, featuring improved modular design, enhanced capabilities and reduced costs.

TSS/BMS4 is designed to measure level in ballast and service tanks and vessel’s draught.

Level measurement principle of TSS/BMS4 is based on periodic purging of compressed air from the system to the tank bottom through an air tube and measurement of the settled air pressure in the tube.

This series of vessels will be built for the Russia´s largest shipyard company Sovcomflot. Vessels will serve the North East Sakhalin Offshore region oil and gas field.

Icebreaking supply vessel (NB 511) will be used as supply between land bases and the offshore drilling and production sites. On the other hand, icebreaking stand-by vessels (NB 512-514) will be used as supply vessels for cargo transfer, stand-by, and rescue duties and for oil spill recovery.
