San Jose, CA, April 22, 2017 --( PR.com )-- California State Lands Commission (CSLC) recently completed a validation exercise of three indicative sampling tools while developing their draft compliance assessment protocols. They evaluated the sampling tools with three different ballast water treatment systems – one UV system and two Electrochlorination systems. In all three assessments, the Ballast-Check 2 results were very similar to the microscopy and flow cytometry results (mean results over three replicates showed a maximum difference of 3 cells/mL, always matching the risk of exceedance level). Chris Brown, Senior Environmental Scientist with the Commission’s Marine Invasive Species Program, presented the results of their validation at the March 16, 2017 ICES/IMO Ballast Water Workgroup meeting. He detailed the planned compliance assessment protocols, if adopted, would be multi-tiered – 1) paperwork, calibration, & functionality; 2) indicative sampling; and 3) full scale testing. Indicative tools such as the Ballast-Check 2 would be employed when the second tier of indicative sampling is deemed necessary.The Turner Designs Ballast-Check™2 is a small, lightweight, highly durable handheld fluorometer ideal for quick indicative compliance checks of ballast water.

Type: Journal Article | Journal: Biofouling | Year: 2016
Biofouling exerts a frictional and cost penalty on ships and is a direct cause of invasion by marine species. These negative consequences provide a unifying purpose for the maritime industry and biosecurity managers to prevent biofouling accumulation and transfer, but important gaps exist between these sectors. This mini-review examines the approach to assessments of ship biofouling among sectors (industry, biosecurity and marine science) and the implications for existing and emerging management of biofouling. The primary distinctions between industry and biosecurity in assessment of vessels biofouling revolve around the resolution of biological information collected and the specific wetted surface areas of primary concern to each sector. The morphological characteristics of biofouling and their effects on propulsion dynamics are of primary concern to industry, with an almost exclusive focus on the vertical sides and flat bottom of hulls and an emphasis on antifouling and operational performance. In contrast, the identity, biogeography, and ecology of translocated organisms is of highest concern to invasion researchers and biosecurity managers and policymakers, especially as it relates to species with known histories of invasion elsewhere. Current management practices often provide adequate, although not complete, provision for hull surfaces, but niche areas are well known to enhance biosecurity risk. As regulations to prevent invasions emerge in this arena, there is a growing opportunity for industry, biosecurity and academic stakeholders to collaborate and harmonize efforts to assess and manage biofouling of ships that should lead to more comprehensive biofouling solutions that promote industry goals while reducing biosecurity risk and greenhouse gas emissions.

As a result of damage from the 2010 Chile and 2011 Japanese teletsunamis, tsunami risk to small craft marinas along the West Coast of the United States has become an important concern. This paper outlines an assessment tool that can be used to quantify the tsunami damage potential in small craft harbors. The methodology is based on the demand and capacity of a floating dock system and uses a Monte Carlo framework to address the uncertainty of input parameters. Detailed numerical modeling and damage calibration data from recent tsunamis are used to benchmark the approach. Results are provided as fragility curves and give a quantitative assessment of survivability. This tool yields an indication as to the survivability and/or failure of a floating dock system of vessels and floating components/piles subject to tsunami events. The objective of the presented effort is to quickly evaluate whether a floating dock is likely to survive or be destroyed by a particular tsunami scenario. © 2016 American Society of Civil Engineers.

Earthquake Spectra | Year: 2011
The Port de Port-au-Prince is the largest seaport in Haiti, and is essential to the country's economy. The Haiti earthquake severely damaged the Port, which disrupted the transport of cargoes into Haiti that were vital to the country's emergency response and post-earthquake recovery. Major contributors to this damage were widespread soil liquefaction, the poor performance of batter piles, and the poor pre-earthquake condition of many components of the Port's waterfront structures. Immediately after the earthquake, a U.S. military task force was deployed to the port to perform emergency repairs needed to reestablish cargo throughput. These repairs restored a significant cargo-throughput capacity at this small but vital seaport within weeks after the earthquake. © 2011, Earthquake Engineering Research Institute.

This paper describes the development and use of objective and subjective evaluation criteria for hydrostatic pressure tests of oil pipelines at marine terminal facilities by a California state agency. Many regulatory agencies require a periodic hydrostatic pressure test (hydrotest or static liquid pressure test) to re-validate the integrity of a pipeline. Performance variables for a typical test include: test duration, test pressure, test medium temperature, ambient environment temperature, and volumetric changes. At California State Lands Commission, Marine Facilities Division, an Excel spreadsheet is used to evaluate test results. The spreadsheet is also used by many marine oil terminals and contracted testing companies. The spreadsheet aids the user to: perform pretest checks, record input, quantify numerical output, and plot graphical output. The pretest checks include calculating fill volume and determining significant trapped air. The graphical output provides a visual presentation for the test variables of time, test medium temperature, ambient environment temperature, actual test pressure, theoretical test pressure, and allowable pressure variance. Acceptable pressure range is shown as a plus or minus bandwidth around the theoretical test pressure, and is based upon the thermal expansion sensitivity of the test medium. For those test results that fall partially outside the acceptable pressure range, interpretive criteria are used involving data trends and correlations. The spreadsheet software is the property of the State; however, it is freely distributed to anyone who requests a copy. An acceptable hydrostatic pressure test is achieved by adequate test preparation, quality data collection, and quantitative, and often times, interpretive results evaluation.

Multifarious proposals for siting, design, construction, and operation of onshore and offshore liquefied natural gas (LNG) import terminals in California have recently undergone a rigorous federal and state regulatory appraisal. The regulations call for compliance with various environmental, public safety, and security mandates encoded in legal statutes. Public safety from the hazards of a large-scale LNG spill over water, during LNG tanker transit or marine terminal operation, emerged as the dominant concern for the affected local communities. To address their apprehension, extensive modeling of potentially perilous beyond design basis spill scenarios, ensuing from natural, accidental, and malevolent intentional events was conducted. It entailed finite element modeling for vessel collision with diverse LNG tanker types and applying computational fluid dynamics to predict the extent of LNG spread over water, atmospheric dispersion of vapor cloud, and the consequences of ignition. The objective was to appraise the adverse impacts of cryogenic fluid, fire propagation, and thermal radiation on humans and property not associated with these LNG terminals. Based on insights from risk analyses for three LNG projects in California, challenges in developing complex mathematical models, assessing public safety, and specification of safety criteria are delineated to benefit others planning similar ventures in California or elsewhere. © 2014 American Society of Civil Engineers.

An overview of the doctrine and the factors considered by the US Supreme Court in a case involving the States of Florida and Georgia for equitable apportionment is presented. The State of Florida filed a case against the State of Georgia in 2013, alleging that Georgia had been extracting an increasing amount of water from interstate rivers to meet its agricultural, industrial, and municipal demand for water. Florida urged the Supreme Court to equitably aportion the Apalachicola-Chattahoochee-Flint Basin water between the two states to solve this problem. The Supreme Court considered the doctrine and the factors from earlier similar cases to decide the case.

Natural Hazards Review | Year: 2016
California's marine oil terminals (MOTs) transport the bulk of the state's requirement of petroleum and petroleum products and constitute a vital infrastructure link to mount successful emergency response after disasters. The ARkStorm scenario may simultaneously affect multiple MOTs and potentially trigger a major disruption in crude supply to refineries and petroleum products to the public, cause likely closure of ports, and significantly impact the economy of the western United States. As disaster relief necessitates timely supply of petroleum products, the feasibility of continuing operations at the state MOTs during the ARkStorm scenario is assessed, taking into consideration the existing design, and operational and procedural safeguards that were primarily built in to address public safety, health, and environmental effects from other hazards. The expected runoffs from ARkStorm are estimated to overwhelm MOTs' drainage design and site-specific flooding analysis and review of mooring analysis for extreme currents is recommended. It is also prudent to formulate strategies to address regional and simultaneous impact of this common cause scenario. © 2014 American Society of Civil Engineers.

This paper outlines an assessment tool which can be used to assess the tsunami hazard to small craft harbors. The methodology is based on the demand and capacity of a floating dock system. Results are provided as fragility curves and give a quantitative assessment of survivability. This tool is not exact and is provided only to give an indication as to survivability and/or failure of a floating dock system of vessels and floating components/piles, subject to tsunami events. The purpose is to quickly evaluate whether or not a floating dock is likely to survive or be destroyed by a tsunami having the input properties. © ASCE.
