Project Scope

Our Client needed a fast turn-around on this project.  DMS conducted a stability analysis on two barges, which contained excavators.  These barges supported construction work on an Army Corp of Engineers (COE) job.

The COE requires a naval architect analysis (NAA) for any ship or barge that contains a crane.  (Reference:  EM385-1-1, section 16.L)  The NAA required a combination of stability analysis and structural assessment and guards against three major dangers:

Vessel capsizes, resulting in loss of crane and vessel. Massive insurance claims.

Crane breaks through deck of vessel.  Damage to vessel and lost project time.

Regulators issue stop work order.  Results in delays of weeks to obtain appropriate engineering approval.

Return on Investment

DMS delivered flexible engineering, which helped our Client in several regions. 

1. Incomplete Documentation

The vessel was missing much of the required engineering drawings and calculations. This is common for any used equipment.  Files go missing, drawings get tossed out.  DMS found a way to supplement the minimal documentation with surveys and conservative assumptions.  In this case, conservative estimates allowed our Client to get back to work, with minimal interruption to schedule.  DMS takes the time to understand your priorities, and we customize our project to those needs.

2. Rapid Development

Throughout the process, our Client’s schedule needed results before engineering was completed.  DMS developed a staged approach that allowed our Client to continue work, while we finished the engineering.  We worked with the regulators to understand their concerns and first obtain temporary authorization.  A few weeks later, we delivered a full engineering analysis for permanent authorization to continue.  This increased our Client’s profit, preventing the loss of millions of dollars in lost revenue.

3.  Emergency Engineering

Our Client received a stop work order and needed the engineering completed immediately.  With less than 24 hr notice, we traveled to the Client’s site and conducted an emergency lightweight survey.  DMS then worked through the weekend to complete our analysis.  By Monday morning, the Client had the required engineering to prove safe operations and continue work.  In total, our Client only lost two days of project time.  DMS understands.  Engineering should not burden the project schedule.

Stability Test

The stability test determines the weight and center of gravity for your ship, which is a critical first step in any stability analysis. At DMS, you get preliminary results on the day of the test.

Light Ship Survey

Light ship surveys check on your weight growth. DMS utilizes computer systems to log our light ship survey and provide fast results. You get preliminary results that same day.

Vessel Modifications

Vessels change a lot during their life. You need an engineer to provide some constructive guidance on all that change.
