Hydrodynamics Engineer - Monaco Internship

Purpose

• Introduction:

  Deepwater floating offshore units are generally moored offshore with a combination of chain and polyester segments in mooring lines (see pictures below).

  Polyester segments change in length over service life due to various phenomena including creep (elongation over time under a constant load) and construction stretch (permanent elongation resulting from a load level never experienced before).

  There is thus an incentive to monitor elongation over service life (required by most Classification Societies). This is generally done through tension monitoring with ALLMS (Anchor Line Load Monitoring System).

  When mounted on chainstoppers on vessel main deck (see pictures below), ALLMS are generally properly working. When ALLMS are mounted on a submerged chainstopper, general industry finding is that ALLMS are not reliable as subject to failure very early in service life.

  Purpose of the internship is to propose alternative techniques to ALLMS to monitor polyester elongation or level of mean tension in mooring lines. Intention is to cover units designed without ALLMS or existing units with failed ALLMS.

  Scope encompasses:

  • Rules requirements
  • Current state of the art, bibliography
  • Approach used in SBM
  • List potential alternatives and advantages / drawbacks (transponders on mooring lines, emitters giving position of accessories, sonar ….)
  • Liaise with Mechanical Equipment specialists to get feedback on feasibility, possibly with suppliers
  • Perform some mooring analyses to help define functional specification of such equipment (like accuracy required on accessory/line position to get acceptable accuracy on mooring line tension)
  • Practicality to deploy the solution

Responsibilities

• There will be three main steps to cover:

  1. Get understanding of the scope and prepare a bibliography
     1. SBM engineering practices
     2. Literature on the topic.

   

  2. List all potential alternatives and set a preliminary list of advantages and drawbacks

   

  3. Prepare input to functional specification on components used for new monitoring techniques

   

   

   

  Your Role

  • • Get a good understanding of the methods used
    • Work with a collaborative and multidiscipline approach (stakeholder in various engineering disciplines, in Operations, etc)
    • Perform numerical analyses and interpret results.
    • Present progress and conclusions to Hydrodynamics department and to various stakeholders.

   

  What it will bring to you:

  • • Exposure to engineering methods used in design and in operations
    • Exposure to multi-discipline environment and technical problem
    • Analytical thinking to compare potential solutions.

Education

• • Engineering schools , 2nd or 3rd year
  • Curious, able to work in multidiscipline team
  • Generic technical background required
  • Notions of instrumentation is a plus
