Excerpt: Why are invasive species problematic? As unavoidable as it might sound for any successful species to expand its geography, today’s world is one in which a species can end up transported 10s of 1000s of km away from its native range, which can quickly create an unnatural imbalance, and which is why compliance is now mandatory. Invasive species are problematic for various reasons: Factors (ie predators) that limit the invasive species where it came from are either absent in the new area, or Invasive species outcompete native species for resources and quickly become dominant, or Invasive species act as a vector for viruses and diseases that the native species do not have resistance for. The latter has been a particularRead more

Excerpt: How does Invasive Species Dispersal in Ballast Water Occur? As vessels take on ballast water in one location, they can inadvertently pick up aquatic organisms. Such organisms can then be transported to a different location when the ship discharges its ballast water. If the new environment is suitable for the organisms, they can establish populations, becoming invasive species. Ballast water discharge can occur in both coastal and open ocean environments, increasing the potential for invasive species to spread to new areas. What are the Ecological Impacts of Ballast Water Invasive Species Dispersal? The ecological impacts of invasive species dispersed by ballast water can be significant. These species can outcompete native species for food and habitat, altering entire ecosystems. They canRead more
Invasive Species in the Marine Environment
23.01.2023Excerpt: FastBallast is capable of determining the phytoplankton cell density of ballast water at the IMO D2 & USCG Discharge Standards (10 to 50 µm range) with a higher degree of confidence than laboratory analysis. As well as its established presence in Europe and Asia, Chelsea Technologies’ FastBallast is in use worldwide, to help ensure industry tools for portable ballast water testing standards. What is an Invasive Species? An invasive species is an organism that is not indigenous, or native, to a particular area; it has ‘invaded’ an area and hence the very specific description ‘invasive’. It is not the same as a successful or rampant species that’s native to the area. Successful species can and do of course extend theirRead more
Compliance Testing on Sea Vessels
15.12.2022Excerpt: The IMO was established following agreement at a UN conference held in Geneva in 1948 and came into existence ten years later, meeting for the first time in 1959. Headquartered in London, United Kingdom, IMO currently has 175 Member States and three Associate Members. Amongst other regulatory responsibilities, the IMO also has responsibility the prevention of marine and atmospheric pollution by ships and for the prevention of invasive species in ballast water. Wash water compliance On January 1st, 2020, a new IMO compliance limit on the sulphur content (SOx) in the fuel oil used onboard ships came into force. Known as IMO 2020, the rule limits the sulphur in the fuel oil used on board ships operating outside designated emissionRead more
Excerpt: Fluorescence ballast water testing tools come in two varieties: STAF (Single Turnover Active Fluorometry) and PAM (Multiple Turnover Pulse Amplitude Modulated). In this article, we’re taking a look at some of the key differences that set these two techniques apart, and how these differences impact the results of ballast water compliance testing. Ballast water testing: why? Ballast water is defined as water taken on board a ship to control trim, list, draught, stability or stresses of the ship. Ballast water operations are essential for the safe operation of ships and a perfectly standard part of shipping – ballast water provides stability and maneuverability both during voyages and during loading and unloading operations. Ships are designed and built to move throughRead more
