Announcement from January 30, 2018:
Dear Valued SSC Members, Partners, and Liaisons:
The Ship Structure Committee is pleased to announce the publication of a new report, SSC-473, titled Methodology for Determining Technical Safe Speeds for Light Ice-Strengthened Government Vessels Operating in Ice, by Mr. John Dolny. The abstract for this exciting new report is below. This report is available for free at the SSC website, through the National Technical Information Service, or download it by clicking HERE. All SSC reports are available free of charge at the SSC website.
ABSTRACT: This report provides an overview of several existing approaches for determining operational limitations of ships in various ice conditions. A detailed technical methodology is proposed to determine technical safe speeds for different ice conditions that is founded on modern principles of modeling ice-structure interaction. The focus is on government vessels that are lightly ice-strengthened, which may be required to operate in pack ice conditions as part of an emergency response effort. A case study is presented of a 5000 ton Ice Class PC5 Patrol Vessel to demonstrate the ice capability assessment procedure and the influence of key parameters.
The SSC greatly appreciates the contributions of the individuals that volunteered their time to participate on the Project Technical Committee, listed below, and thanks them heartily! They were the subject matter expert representatives of the Ship Structure Committee to the contractor, performing technical oversight during contracting, advising the contractor in cognizant matters pertaining the contract of the which the agencies were aware, and performing technical peer review of the work in progress and upon completion.
