Offshore Structural Analysis Computer System (SACS)

Introduction

The training on the application and usage of the SACS software will be carried as per the attached proposed plan. However on confirmation of the training, the same can be altered as mutually suitable. Software access to each individual candidate will be provided by us.

Objectives

By the end of the course, participants will be able to use of the SACS software.

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.
