Design Concepts

Non-Standard Structural Designs for Increased Resistance to Collision and Grounding. (pdf format)

This paper was developed some time ago and is very general in nature.  It is intended to encourage comments on alternative vessel structural arrangements to improve resistance to collisions and groundings.  It is suggested that comments be divided into two categories:

A) General Energy Absorbing Schemes (as discussed below):
B) Specific Examples of Structural Alternatives – as for example they appear in more recent publications such as:
• Kim, Y.K., et al, “Behavior of Double Hull VLCCs in Collision.” PRADS 95.
• Kitamura, O., “Comparative Study on Collision Resistance of Side Structure,” SNAME, Marine Technology, Oct. 1997.

It is suggested that in providing the specific examples, a description of the structural alternative and sketch can be provided.  If it is envisioned that there will be impacts on steel weight and production costs, these should be noted as well.  At a later date we may likely consider developing dimensions and scantlings for a specific vessel and apply the procedures from the other working groups in order to carry out a comparative analysis.
 

Objectives

• Identify important reference work to define the state of the art in designing for collision and grounding
• Identify the goals to be achieved by vessel structure in collisions and groundings. Subdivide by vessel type, cargo and mission. Interface with WG-2 and WG-3.
• Identify structural mechanisms that hold promise in achieving these goals. Interface with WG-1 and WG-2.
• Postulate new structural arrangements that hold potential in maximizing the goals. Identify the potential impact on other vessel functions.
• Evaluate the performance of the novel structural arrangements and compare to more conventional schemes. Interface with WG-1 and WG-2.

Work Plan, Tasks and Methods

• Material compiled by workgroup members will be posted on the workgroup web pages for comment and question throughout the work of the panel.
• Work will follow an iterative process:
• Team leaders - post material for other members to review and discuss.
• WG members - provide comment, critique, alternative approaches, supporting or conflicting data, etc.
• Team leaders - integrate feedback, model, assess, post feedback

• Designs developed by WG4 will be assessed by WG1. WG1 and WG4 will work together to identify important design parameters to be included in the damage models.
