Scana Skarpenord Langesund (Norway) has launched innovative marine precision level radar capable of providing ullage measurements of ±0.01%. First introduced as BM70/50 in 1992, the new upgrade BM70MP represents a two-year collaboration with Germany-based KROHNE. The new radar utilizes a high precision microwave board and a linear sweep controller. Its stand-alone operation, ease of servicing or replacing components and limited radar beam angle, makes it an optimal solution for crude oil tankers, as well as all other types of tank ships.

The ullage accuracy is ±2mm and the total measurement range 20 – 35 meters. The radar’s ±6 degree beam accommodates both low free space (footprint) and high trim/list. BM70MP is a stand-alone system and is fed from a single power source. It allows ullage measurements to be displayed even under a central computer failure. Major components (electronics, antenna and coupler) may be serviced/replaced without any gas pressure being released from the tank, due to a unique, heavy-duty glass/steel barrier incorporated below the antenna coupler. The software package helps shipyards to compile a detailed presentation of the total tank picture. Elements affecting correct microwave measurement, such as stringers or large pipes are easily identified and this potential interference can be easily eliminated.The new radar fully complies with marine standards, including EEx de IIC T1-T6, and is approved by all major classification societies.
