Allseas - Support (ongoing)

Allseas - VPM (2005-2016)

A set of applications to support the daily progress reporting of the pipe lay vessels Solitaire, Lorelay, Audacia and the subsea support vessel Calamity Jane.
Components include tools for Field Engineers to report production and downtime. Also facilities for Bridge (Weather and positions), Warehouse (consumables and pipe supply), Personnel and Safety Officers (safety drills and incidents).
Data from all vessels is collected via satellite into a central SQL Server database in Delft. The VPM portal provides management and users with valuable insight into the status and performance via summaries, operating details and progress charts on a daily basis.
In particular the achievement of a 'single source' database provides management consistent view of operations across all departments (Planning, Cost Control, Quality Control, Piping Department and Technical Services). Since the introduction of VPM, measurement against Key Performance Indicators and 'End of Year' reporting has improved significantly.

Allseas - MPP (2005-2017)

Single–handedly designed and implemented an ASP.Net MVC/Razor based portal to track all externally contracted Quality Control Inspectors.

Functions include:

  • scheduling inspection tasks
  • optimizing inspectors over worldwide located fabrication yards
  • management reports on actual and forecasted project expenses

The timesheet module generated detailed billing instructions per task for the contracting agencies.
This module significantly reduced billing errors and conflicts with the agencies

Allseas - PTS (2005-2017)

PTS

Software application for tracking offshore pipe line construction. Single–handedly designed, developed and deployed a system of software modules to track pipes and structures (PLEMs PLETs etc.) as they are welded into the pipe line. Pipe line laying data is transmitted in near real-time to Delft where progress is reviewed by the project managers. Included tools for QC (Quality Control) Supervisors and Inspectors to report on weld inspections for approved/rejected welds. Included a custom replicator to retrieve vessel pipe laying data in near realtime from the vessels to Delft. Data retrieval used expensive satellite connections so efficiency and speed were essential. Implemented management performance charts on the internal management portal VPM (see below). Efficiency improvements since the introduction of this system are: less errors in pipe numbers and accurate daily reporting to the client representative. The system also allows more accurate and timely post-project reporting to the pipeline owner (data book) requiring less resources.
