Navigation of the Northern regions is becoming increasingly viable and correspondingly the interest in research and commercial exploitation has been steadily rising. Increased maritime activity in the region results in a need for greater presence by the Navy, Coast Guard and other government agencies. In turn this increases the need for government vessels, and their equipment, to be designed to operate in low temperature environments.
This course was developed with input and guidance from ASNE and BMT Technology to provide participants with an enhanced knowledge of the state-of-the-art low temperature environment technologies, design assessment procedures, regulatory requirements and other aspects to be considered for government vessels operating in ice conditions.
Regulations for operating in polar waters: UNCLOS, IMO, Arctic Council and National Arctic regulatory regimes
