Norwegian ocean science know-how supplier Kongsberg Discovery has launched EM®SBP software program system, which presents sub-bottom profiling functionality for Kongsberg’s deep-water multi beam echo sounder (MBES) techniques EM 124 and EM 304, with out the necessity for extra {hardware}.
A sub-bottom profiling system enhances MBES surveys tailor-made to map the seabed and sub-seafloor.
Gathering sub-bottom information is important to grasp sediment thickness and distribution, in addition to for detecting buried objects or infrastructure, resembling boulders or pipelines.
A sub-bottom sign will need to have particular properties and be personalized for the sub-bottom goal.
Historically, this has required tools that’s usually fairly massive, particularly for probably the most highly effective techniques that may penetrate sediment in very deep water.
EM®SBP presents sub-bottom profiling functionality with out the necessity for any devoted transducers or cupboard of electronics, in line with Kongsberg Discovery.
Which means no extra {hardware} past what’s used for the EM 124 or EM 304 MBES techniques – which is normally already accessible on board the vessel. This functionality saves price, area, complexity, and energy consumption, the corporate claims.
The set up contains solely a pc and the software program. The applying can be utilized as needed, additionally with versatile sub-bottom versus bathymetry protection relying on undertaking necessities.
Primarily, the EM®SBP software program ‘borrows’ the EM 124/304 {hardware} to transmit the downward-looking sub-bottom alerts at a given interval. The sequence of sub-bottom versus multibeam alerts, or pings, is consumer selectable.
The EM®SBP software program configures the sub-bottom transmit and obtain parameters, picks up the returned echoes, and processes the information to create sub-bottom photographs which might be visualized and logged to file.
The efficiency of the sub-bottom information is determined by the utilized MBES frequency vary and configuration. EM®SBP generates sub-bottom alerts from the first multibeam frequencies, in addition to parametric low-frequency alerts. The software program handles, processes and pictures the first and parametric alerts concurrently.
